Re: [JBoss-user] JBoss On Linux

[David Ward]

Rod,

Input appreciated and respected, however I think to help Peter we need 
to keep off the performance bunny hole.  He never said performance was 
his problem.

As a side note, you're right: what you tested (startup time) was far 
from a valid performance benchmark.  JVMs intended to boost server 
performance don't try to be fast for startup times (if you want that, 
use the -client jvm option, not -server).  They care more about being 
fast for things servers care about after they're already up and running 
- like handling multiple threads quickly, optimizing server hotspots 
like network connections, and effective memory management of large heaps 
under load, etc.  Besides, I take benchmarks with a grain of salt - each 
custom app does different things, and thus it's impossible that a 
generic benchmark is going to tell you what you really need to know - 
how does tool A stack up against tool B with YOUR application...

Oh shoot, now you got me goin' down the bunny hole.  Seriously, Peter - 
  my guess is you've either got a resource leak or an inappropriate 
resource configuration.  Start by looking at file descriptors.

Just my 2 cents (again),
David

Downloaded JRockit and launched a large J2EE application in debug mode. JBoss started in 1:24. Using Sun's JDK 1.4 JVM the same application started in 1:32. I would call that a noise-level improvement given JRockit is a commercial product focused on performance. Not a valid benchmark but then if your compiled code is really all that you would expect to see more than a fraction of 1% improvement. Conclusion: JRockit is not worth the disk space it's sitting on:)

Peter,

I've read others' responses to your problems, and they all seem to be
addressing the wrong thing: performance.  What you describe does not
sound like a performance problem (neither of speed nor memory
management).  You never said the app was slow, so why do you care about
"SPECjAppServer2002 benchmarks" and the like?

It sounds more like a resource leak to me, my first guess being of file
descriptors.  On Linux/UNIX based systems, socket connections (like to
your mailserver and database) - not just files - use file descriptors.
If that's the case, something - or a growing number of "things" - are
holding onto sockets or files (same thing to UNIX) and not letting go.

If I were you I would do 2 things:

1) In the short term, increase your system setting for max # of file
descriptors (in my experience, OS defaults are stunningly low for
production systems).  This will require a system reboot to take effect.

2) Find out where your resource leak is.  It may be there's one in your
application (that runs in jboss), and then the cron runs that might
require a lot of descriptors too.  Together, they could use up to your
limit.  To diagnose this you might have to employ more than just one
tool.  netstat (comes with Linux/UNIX), filemon
(http://www.sysinternals.com/linux/utilities/filemon.shtml) , Optimizeit
(http://www.borland.com/optimizeit/optimizeit_profiler/), etc.

Last, maybe there really isn't a leak, but the nature of your
application, plus the crons that run at specific times, just simply
require more file descriptors than what your system has configured.
Upping that value might prove to be all you need to do.  If it never
grows past that max, you're set - no leak.  Unfortunately, without doing
some surfing, I can't tell you where to set it for your system, or what
the best value should be.  I'll leave that as an exercise for you.  ;)

Anyway, hope this helps.  And sorry in advance if it ends up leading you
down the wrong path.  I just wanted to share what your problem "smelled
like" to me.

After roughly a week many of the boxes start to experience weird

cases we cannot contact our database; in the latest case we're unable to 
get a connection to the local jndi server (localhost:1099). Sometimes a 
simple restart of jboss will sometimes solves the problems, othertimes 
we have to restart linux. The times of the crashes are roughly 4am and 
sometimes 6am, so it's likely caused by a cron job running at those 
times, which we're currently looking into. Has anyone experienced 
similar problems?

Re: [JBoss-user] How to develop Weblogic Startup Class like feature in JBoss 3.2? Please Help

[David Ward]

The MBean option would work, however if you need to implement startup/shutdown
capability that is agnostic across app servers, may I suggest the following:

In the Servlet 2.3 spec, ServletContextListeners were introduced. Implement one
of those and enter it a war's web.xml file. Then add this war file to your ear
that also contains your ejb-jar files (if you need more than just a web app).
Then, you can trigger startup from the contextInitialized() method and shutdown
on the contextDestroyed() method. This is a standard J2EE way of doing
startup/shutdown hooks of J2EE applications, and is therefore appserver agnostic.

If you can't use Servlet 2.3 spec, you can use a similar (though not as elegant)
mechanism in 2.2. Write a Serlvet instead of a ServletContextListener, and do
your startup/shutdown code in the init()/destroy() methods, respectively. Then
in web.xml, register the servlet *and be sure to add* a
1 element (the # doesn't really matter unless
you want to order it with other servlets).

If you are using the 2.3 spec, double check the following:
1) Make sure you have the appropriate listener tag in web.xml.
2) Make sure your web.xml is referring to the servlet 2.3 spec in the dtd line
at the top, NOT 2.2.
3) Make sure your listener class ended up in your war file in the correct place,
with the packaging matching that noted in your web.xml listener tag.

Hope this helps,
David

[JBoss-user] Cocoon war dir hot-redeploy causes JBoss Shutdown

[David Ward]

Hi, all.  My company has found a bug, which I've since entered at 
SourceForge.  Thought I'd copy/paste the details here to give it some 
visibility and see if others have seen the same problem.  Thanks!

Bug: 840496
https://sourceforge.net/tracker/?func=detail&atid=376685&aid=840496&group_id=22866
I've discovered a problem that only happens with jboss
3.0 + tomcat + cocoon 2.0 + expanded war directory,
relating to hot-redeploy. Basically, if you have a
cocoon.war/ *directory* web application, and touch it's
web.xml file, JBoss shuts down! Here are the steps to
re-create:
1) Download a completely fresh
jboss-3.0.7_tomcat-4.1.24 from sourceforge.
2) Download a completely fresh cocoon-2.0.4 (vm14) from
apache.
3) Dropped cocoon.war in jboss' deploy directory.
4) Started up jboss.
5) Hit the cocoon servlet (got a sitemap error but
didn't care)
6) "touch" cocoon.war.
7) NO REDEPLOY PROBLEM
8) Hit the cocoon servlet (got same sitemap error but
still didn't care - at least could still hit it).
9) Stop jboss.
10) Delete the db, tmp and log dirs to be completely
clean distro again.
11) Explode the cocoon.war file into cocoon.war/
*DIRECTORY INSTEAD*.
12) Start up jboss.
13) Hit the cocoon servlet (sitemap error; still don't
care)
14) "touch" cocoon.war/WEB-INF/web.xml
15) *** REDEPLOY PROBLEM: jboss shuts down!! ***
JBoss/Jetty does not do this. JBoss 3.2.x does not do
this. A JBoss/Tomcat webapp without Cocoon does not do
this. JBoss/Tomcat with a Cocoon war *file* does not
do this. It has to be JBoss 3.0/Tomcat with a Cocoon
2.0 war *directory*, and you touch it's web.xml file to
cause a redeploy. I have tested it on many different
combinations, and here is the breakdown:
1) jboss-3.0.7_tomcat-4.1.24 + cocoon-2.0.4 - FAILED
2) jboss-3.0.8_tomcat-4.1.24 + cocoon-2.0.4 - FAILED
3) jboss-3.0.8_tomcat-4.1.27 + cocoon-2.0.4 - FAILED
4) jboss-3.0.8_tomcat-4.1.29 + cocoon-2.0.4 - FAILED
5) jboss-3.2.2 (tomcat_4.1.27) + cocoon-2.0.4 - PASSED
6) jboss-3.0.8_tomcat-4.1.24 + cocoon-2.1.2 - PASSED,
though 500 errors
Something was fixed in JBoss 3.2.2 / Tomcat that fixed
this problem. Does anyone have any idea what this was?
Unfortunately, we cannot upgrade to JBoss 3.2.2 right
now. If the fix is known, can it be backported back to
3.0? A jboss-3.0.9_tomcat-4.1.29 with the backported
fix would be awesome and greatly appreciated!
BTW, with JBoss 3.2.2, it looks like the shutdown was
intercepted; here's a line from the console:
22:43:58,980 INFO [STDOUT] Mon Nov 03 22:43:58 EST
2003 SHUTDOWN : System.exit() was not called
When I see that line with 3.2.2, the redeploy finishes
and JBoss does not shutdown. Maybe find where that log
is done and see what can be similarly done in 3.0.x to
intercept the shutdown?
Last bit of info: This is using Sun JDK 1.4.1 and
1.4.2. It is recreateable on Windows; not sure about
Linux and MacOSX.
Thanks!
David
PS: Scott, I apologize if it was bad for me to assign it to you.  I did 
it because I know you've been the one in the past that has dealt with 
web-tier integration into jboss, so I thought you'd be interested in 
this one.

[JBoss-user] weblogic -> jboss transition/translation project?

[David Ward]

Hi, all -

Didn't there used to be a project that given weblogic-specific deployment
descriptors, jboss could automagically translate it to it's own needs and use it
(dynamically at deployment time)?

I thought this was undertaken to try to ease migration from weblogic to jboss.
Am I smoking something or am I remembering correctly?  Any pointers to
documentation, list/form threads, etc. appreciated.

Thanks,
David

Oh yeah, what version of weblogic -> jboss was this?  My current project
assignment is running weblogic 8.1, and thinking of moving to jboss 3.2.2...

Re: [JBoss-user] Invoking executables from J2EE world

[David Ward]

Manoj,

java.lang.Runtime.getRuntime().exec(String);
(There are 6 different overloaded exec methods to choose from.)

Don't do this from an EJB as it is not allowed per ejb spec.
No problem doing it from your web tier, though.

Hope this helps,

Re: [JBoss-user] execute some command at end of deployment/startup

[David Ward]

Ittay,

I know you want to initialize your beans; I am telling you how you can do it
using a standard j2ee technique.

If you have an ear with an ejb-jar and a war in it (even if the war is just for
this purpose), once your entire app is started up, the contextInitialized method
will be called in your ServletContextListener.  It is in that method that you
can get a handle on some local (or remote if you want) interfaces to your beans
and do your initialization.  All this should happen as part of (the end of) the
deploy of your app before traffic starts hitting it.

The above mechanism is 100% appserver-agnostic, and pure j2ee.  Using MBeans and
 and stuff like that is not guaranteed to work on all appservers.

David

Re: [JBoss-user] @jboss-net: xdoclet module

[David Ward]

I think it would be a *great* idea to have this downloadable at jboss'
sourceforge page.  The jar could be available either:

1) As part of the jboss download (maybe in ${jboss.home}/lib or
${jboss.home}/docs/xdoclet/ or...)

2) As a separate download, but still contextual to each jboss release (just in
case it changes due to a change in jboss for that version).

I'm guessing #1 is easier, and it's the one I would vote for!

Thanks for bringing this up!
David

Re: [JBoss-user] execute some command at end of deployment/startup

[David Ward]

Ittay,

Implement a javax.servlet.ServletContextListener, add it to your web.xml of your
war (if you have one, otherwise make one), and then you can put stuff in the
contextInitialized(ServletContextEvent) and
contextDestroyed(ServletContextEvent) methods.  It's a good appserver agnostic
startup/shutdown hook mechanism.

Re: [JBoss-user] Jetty and work files

[David Ward]

Quote from: 
http://www.coredevelopers.net/technology/jetty/jetty-jboss-faq.jsp

"I want to change where Jetty writes it's temporary files. (revised: 
02/06/2003)
Jetty, being a good java citizen, respects the 'java.io.tmpdir' property 
(defaults to /tmp on Unix). Try setting this as you start up JBoss (see 
the following item) to your required directory e.g. 
$JBOSS_HOME/server/default/tmp."

So basically, set the java.io.tmpdir -D property when jboss starts up 
(edit your run.sh script or set it in your $JAVA_OPTS).

Hope this helps,
David
Lars Hoss escribió::
Hi all!

Is it possible to tell Jetty not to store the work files below /tmp 
(using Linux)?
Currently whenever I start Jetty it creates a directory like 
"Jetty_0_0_0_..." below /tmp.
This isn't very feasible because our cronjob removes files below /tmp 
after some days
of inactivity. Setting the "scratchdir" variable in webdefault.xml isn't 
very useable as well for the work
files of all webapps will go into one single directory.

Any suggestions?

Thanks in advance,
Lars

[JBoss-user] Re: [JBoss-user] J2EE en españa

[David Ward]

I did translate it (I put it in quotes), but here it is again:

"It is clear that we do not make distinction of (per) country.  The idea is to
construct a Hispanic community of (on/about) JBoss."

Just so everyone understands, the point of all the messages in Spanish was that
a new list/forum was being created.  Postings on jboss-user were to get
interest/support/ideas for and advertise this new community to those jboss-user
subscribers who speak Spanish.

Here's the list: http://listas.javahispano.org/cgi-bin/mailman/listinfo/jboss
Here's the initial forum:
http://www.javahispano.org/forums.thread.action?forum=2&thread=67384417&id=1801690075

Personally, I am in full support of spin-off language-specific lists/forums if
it helps people - especially if it helps them spread the use of JBoss!  ;)  That
being said, I am happy to see other languages on the main jboss-user list,
because they need a place to start from and meet other people, right?

[JBoss-user] Re: [JBoss-user] J2EE en españa

[David Ward]

I think it's a great idea to have a Jboss list in Spanish (I'm looking forward
to participating in it).  I also agree it's probably a good idea that the main
jboss-user list stays mostly in English, since it seems to be the common
denominator for programmers.

However, let's all try to be just a bit more tolerant of a few postings here and
there in other languages.  (I've also seen German and some French - like from
Marc Fleury himself.) This is supposed to be a leading *world-wide community*,
right?  Let me translate Jorge's message for you, so you can catch the drift of
the postive attitude the recent Spanish postings have had:  "It is clear that we
do not make distinction of (per) country.  The idea is to construct a Hispanic
community of (on/about) JBoss."

A new Spanish-speaking list has been created, and I expect to see the traffic
move over there.  But again, please tolerate a few initial messages in Spanish
here for people who haven't heard of the new Spanish list, so that those of us
that speak Spanish can help direct them over to the other list.

Thanks for your patience/understanding/tolerance,
David

[JBoss-user] sychronization problem with flushAuthenticationCache?

[David Ward]

Using jboss-3.0.6_tomcat-4.1.18 on Solaris 9, Sun JDK 1.4.1_01, web+ejb+db app,
all using J2EE declarative security.

There are times in our application where we have to use the MBeanServer to call
flushAuthenticationCache("ourdomain") on the JaasSecurityManagerService.  We are
looking forward to 3.0.7 being released so we can just clear out roles for
specific users, but in the meantime we have to flush the whole thing.  Even with
the fix, though, there seems to be a problem...

It turns out that if it's timed just right, flushing the auth cache during a
request to a secure resource on the server could cause
HttpServletRequest.isUserInRole(String) to return false when it should return
true.  We are able to recreate this by hitting a servlet (that calls the flush)
multiple times in one browser while someone else is using the application
normally in another.  At some point the user ends up with a "you do not have
access to this URL" error - when they should have access.

I've poured through the mailing list, forums and sourceforge tracker, and see a
handful of other people who have experienced *similar* problems (including
myself in a bug that was patched in 2.4.7+patch - thanks Scott! ;) ).  Please
let me know if this is a known issue or not.  If not, I can enter a bug at
sourceforge.  If need be, I can also provide a test case.

Thanks muchly,
David

Darren,

Can you try something like this?
(Make sure these tags create the xml you need, but you get the idea.)


/**
 * @ejb.interface-method
 */
public void setStartDate(Date pStartDate) {
setActualStartDate(pStartDate);
setDeadlineDate( new Date(pStartDate.getTime() + 43200) );
}

/**

 */
public abstract void setActualStartDate(Date pStartDate);

/**
 * @ejb.interface-method
 * @ejb.persistence column-name="DEADLINE_DATE"
 */
public abstract void setDeadlineDate(Date pDeadlineDate);


Hope this helps,

Re: AW: [JBoss-user] JBoss: Not Ready For Prime Time

[David Ward]

You've said that many times; you're starting to sound like a broken record.

Everyone has a right to their opinion, however the jboss-USER list is a place
for USERS of jboss to voice theirs.  Go set up a NOT-jboss-user list and voice
your opinion there.  If you're not going to contribute, and especially if you're
not going to even use it, then get off this list.  I'm surprised the list owners
haven't booted you off already.

Bet of luck to you with your $XX,XXX bills,

[JBoss-user] managed transaction problem

[David Ward]

Hello, all.

I'm having transaction trouble with jboss-3.0.6/jetty, jdk 1.4.1_02 and Oracle
9i w/ojdbc14.jar.  Please see the ASCII-art diagram below (hopefully it will
line up for everyone).

  Client
|
   (1)
|
V
  SLSB--(2)-->[Oracle]
|^
   (3)   |
||
V|
 JMS Topic  (5)
||
   (4)   |
||
V|
Subscriber---+

Step:
(1) Client calls SLSB (stateless session bean)
(2) SLSB puts new data into Oracle database
(3) SLSB sends a message to a JMS Topic saying data has been created
(4) Topic notified Subscriber
(5) Subscriber pulls new data from database

All that gets sent to the Subscriber is the key for the new data that was
successfully inserted by the SLSB.  The problem is that when the Subscriber goes
to pull the data from Oracle, it's not there (yet!).  From what I can tell, the
JDBC Connection the SLSB was using hasn't been commited yet, so the Connection
the Subscriber is using can't see the inserted data yet.

Right now I have transaction type of Required on the SLSB, but I've tried
RequiresNew and that doesn't work.  I've also tried NotSupported and Never for
hope of doing my own JDBC Connection commit, but then the
org.jboss.adapter.jdbc.local.LocalManagedConnection complains that I can't do my
own commit (or change the autoCommit setting) during a managed transaction.

Please help!  Any and all suggestions welcome.

Thanks,
David

[JBoss-user] jboss-3.0.7?

[David Ward]

Curious when 3.0.7 is going to be released.  There's 2 things that are
supposedly fixed that would be very helpful for us (and probably others) to get
our hands on:

1) Getting shutdown client class to work again (don't know the tracker id but
I've seen talk about this on the user list).

2) [ 677614 ] method to remove single Principal from authentication cache
http://sourceforge.net/tracker/index.php?func=detail&aid=677614&group_id=22866&atid=376688

Thanks!
David

Re: Re[2]: [JBoss-user] simple Class-Path/ jar dependency question

[David Ward]

Try:

import org.apache.log4j.*;

instead of:

import org.apache.log4j;

Better yet, just import the Logger class specifically.  You don't need the whole
package.

Now, if the bad import line was just a typo on your part (which now that I think
about it, it probably is - otherwise you wouldn't be able to compile), double
check that there is a a log4j.jar in $JBOSS_HOME/server/default/lib/.

Re: [JBoss-user] simple Class-Path/ jar dependency question

[David Ward]

Log4J comes with JBoss, and you have *no need* to include it in *any* of your
application units.  Ready to use, out of the box - no messing with classpath! 
Why would you want log4j available *only* to one app?  IMHO a logging service is
a nice thing for an app server to provide to all deployed applications, and
Log4J's the way to go...

Re: [JBoss-user] Starting threads from session beans

[David Ward]

Alex,

It is not permissible.  It is not in the j2ee spec; it is in the ejb spec.

ejb-2_0-fr2-spec.pdf: 24.1.2 Programming restrictions, page 495:

"The enterprise bean must not attempt to manage threads. The enterprise bean
must not attempt to start, stop, suspend, or resume a thread; or to change a
thread's priority or name. The enterprise bean must not attempt to manage thread
groups.

- These functions are reserved for the EJB Container. Allowing the enterprise
bean to manage threads would decrease the Container s ability to properly manage
the runtime environment."

Someone else who knows more than me can answer your last question, but I'll
guess you're right - the tx (and probably security) information is probably
related at the thread level.  A possible implementation is the
java.lang.ThreadLocal class.

David

Re: [JBoss-user] OT: Data Internationalisation Best Practice

[David Ward]

(Sending this again as my first reply somehow didn't appear to make it...)

Maybe you could do something like this:

++
| product|
++
| product_key  number pk |
| name_i18n_id number|
| desc_i18n_id number|
++
| sequence: product_key  |
++
 |
 V
++
|i18n_text   |
++
| i18n_keynumber pk  |
| i18n_id number |
| locale  varchar(5) |
| value   varchar|
++
| sequence:i18n_key  |
| contstraint: i18n_id + locale = unique |
++
example data:

product
===
product_keyname_i18n_iddesc_i18n_id

25 41   42
i18n_text

i18n_keyi18n_idlocalevalue

  182 42 en_US freakin' easy to use
  183 42 esmuy fácil utilizar
DB note:

Unless you only care about Western/European languages, I suggest you 
*install* your database as Unicode, UTF-8.  You will then be able to 
support Japanese, Simplified Chinese, etc.

Possible Code:
==
You could either do the CMR's to pull the strings for the value objects, 
or you could have a singleton, caching I18NTextFactory that returns 
I18NText objects that maintain the Locale->String mappings.

Maybe:

ProductValue.java
-
public long getDescriptionId() {
return mDescriptionId;
}
public String getDescription(Locale pLocale) {
if (mDescriptionText == null) {
mDescriptionText =
I18NTextFactory.getInstance().getText(mDescriptionId);
}
return mDescriptionText.getValue(pLocale);
}
private I18NText mDescriptionText = null;
productPage.jsp
===
<%= productValue.getDescription( request.getLocale() ) %>

Let me know how you decide to do it as i18n is very interesting to me.

Hi all,
 
This is way off JBoss as a topic, but because of the expertise in
developing J2EE apps and because the xpetstore applicaiton shows
off using JBoss as a J2EE server I thought I'd ask this design
question here anyway. Hope that's okay.
 
we are looking at internationalising the
xpetstore application http://xpetstore.sourceforge.net
 
Luckily, Herve build the application using Resource bundles for
the front end, so all the JSPs can grab all the web-site's labels
from the correct language Resource Bundle. Great!
 
However, some data that is represented in the database might
not be so easy to internationalise. For example, the application is
a basic webstore, so it has a product catalogue with the following
database structure:
 
+--+
|Category   |   
+--+
|  name  |
|  description  | 
|   etc|

Now, some of this information must obviously be displayed on
the website, such as names, descriptions and prices. However
they are currently entered in the database as english.

Re: [JBoss-user] new datasource

Put it in the deploy subdir, and it will be hot-deployed.  Make sure you 
have the appropriate jdbc driver in the lib subdir first.

eg:
$JBOSS_HOME/server/default/lib/ojdbc14.jar
$JBOSS_HOME/server/default/deploy/oracle-ds.xml

Re: [JBoss-user] somewhat off topic - Operations logging

[David Ward]

Have you read *any* of the Log4J docs (api or otherwise) or tried using it!?!?

Log4J is very solid and very robust.  It can log not just to file (including
rolling) but to a database, to email, to jms, to syslog, etc.  It can be
configured via xml (preferred) or properties.  Filtering and log levels are easy
to use.  You can use standard formats or define your own.  It can be managed via
JMX.  Logging can be done asyncronously. ... The list goes on and on.

http://jakarta.apache.org/log4j/docs/documentation.html
http://jakarta.apache.org/log4j/docs/api/index.html

And what do you mean by "lose packets?"  You mean lose a log record?  I've never
seen it happen with Log4J.

As an aside, as much as I love Log4J (and use it in all my apps now) - I don't
use its API directly.  I use Jakarta Commons Logging, which sits on TOP of Log4J
(or JDK1.4 logging, or whatever - it's pluggable).  It works very well, and I
don't lose any of my Log4J features.  It just allows the site administrator to
change the actual logging implementation if he want to.  The code just uses the
interfaces.  Of course, I don't see why anyone would NOT want to use Log4J for
the logging implementation...

Hello!
I am having problems after flushing the authentication cache at runtime. I
am using the code which is at the bottom of the email. The flush is done
correctly, although, the user which executes this code looses all its
permissions after this. According to the documentation this code drops all
cached credentials and flushes them to the specified DataSource. How can I
avoid to have the credentials being dropped from memory, or how can I reload
them.
I am using this code only when I update User's data (Roles and/or
Password).
Any help would be welcome.
Thanks in advance,

Re: [JBoss-user] Jetty and form based authentication

[David Ward]

But then everyone would have to log in to access any of your pages.  If you need
to know who the user is on all pages (if they're logged in) why don't you just,
on successful login (ie: there is a non-null Principal in the request), stuff it
into the httpsession yourself, then access that variable from your pages?  It
gets cleared out on logout (ie: session.invalidate()).  If you don't have a
single servlet controller that fronts your app to put the Principal in the
session, you could instead do it via a javax.servlet.Filter that is configured
to intercept everything in your servlet context.

Hope this helps,
David

Re: [JBoss-user] Form based authentication

[David Ward]

Silvester,

I'll share what I do.  I have a single servlet that is a central controller that
delegates processing and dispatches requests to jp's (based on pathInfo). 
However, *I have 2 servlet mappings to it*.

/myapp/web/pathInfo - myapp is the context, web is the servlet, pathInfo (and
request params) tell me how to process and where to request dispatch to.

/myapp/sweb/pathInfo - same as above except sweb (notice the "s") is a different
mapping *to the same servlet*, except it also is a web protected resource.

I have a dynamic login/logout link on each page (based on principal in request),
which simply links back to itself except replacing "web" with "sweb".  After the
user logs in, he/she ends up visually back to where he/she started, though the
path in the url is a bit different.

Now, it sounds like you have an actual login form on each of your pages.  I've
not done that, but I'm guessing you could do the same thing as me, except just
pass along the username and password to a dummy login with no display that
onLoad (JavaScript) simply submits for you.  But 1) that seems hokey, and 2) you
would want to make sure you're using SSL otherwise your username and password
are plain-text'ing over the net.  What do other people do in this circumstance?

David

Re: [JBoss-user] j_secuity_check

[David Ward]

Gabriel,

Sorry; I didn't know what you initially meant.

Well, I just edited my login page to spit out some debug.  I enumerated 
over and logged all request headers, request attributes and request 
parameters, and  the only stuff that was visible in the implicit 
request object on the login page were headers.  Of the headers, the only 
one that might be remotely useful is the "referer" header, which says 
where you came *from*.  I didn't see anything about where you were 
trying to go *to*.

If you figure this one out, please share.

Thanks,
David

Brian,

Look at the "Deprecated and Removed" section on this page: 
http://xdoclet.sourceforge.net/development/design.html .  Yes, 
@use-soft-locking is going to go away (at least in XDoclet 2.0).

Now that I think of it, wasn't some version of JBoss (3.2 or 4) going to 
support Optimistic Locking?  Can someone tell me which version?

Thanks,
David

(PS: Sorry for the cross-post.)

Brian Wallis escribió::
XDoclet (1.2b1) generates code for optomistic locking when given the

increment in the ejbStore() method of the CMP class.

But this doesn't work in JBoss 3 (3.0.4) and probably cannot be guarenteed to 
work in any CMP implementation since (according to the spec)  ejbStore() can 
be called at any time and must be called *before* ejbFind(...) calls. 
(section 10.7.4 5th para, 10.5.1 7th bullet, ..  and thanks to Dain on the 
Jboss-User list for pointing this out to me). 

Perhaps this use-soft-locking option should be deprecated?

brian wallis...

P.S.  I'm not sure why it needs to call ejbStore() rather than ejbLoad() but 
that is what the spec says (Version 2.0, 14 August 2001)

Re: [JBoss-user] JBossMQ, JMS & MDB

[David Ward]

Yong,

I don't know the answer to your question, but I thought I'd share with 
you something we learned on a past project:

We also *thought* it would be a good idea to have an MDB receive 
messages for the sake of queing up email to send (the MDB used the 
JavaMail api inside it), thinking it would return application flow back 
to the user faster.  We learned it's not.

Using OptimizeIt!, we found the serialization of the objects sent to the 
MDB took longer than the actual time sending the email inside the 
onMessage method of the MDB.  The MDB container had to serialize the 
objects, even though it was in the same JVM, since it needed to 
guarantee durability.

Just something for you to consider before you go too far down this path. 
 The only thing you might be buying yourself is a slower, more 
complicated app - and maybe a little experience working with MDB's.

David

Kim, Yong escribió::
Hi,
I am really in a state of confusion with regards to JBossMQ, JMS & MDB.  I
am not sure if my configuration is screwed up or the fact that I have
believed as true has turned out to be false!  Please bear with me.

I have created a MDB called EmailManagerMDB.  Currently, it has nothing in
it.  It's basically a skeleton code.  Inside the onMessage method, it only
has System.out.println method.  I also created a stand-alone Java
application that sends a message to a queue called, "queue/EmailQueue" which
seems to be working fine.  I have checked that this is working from
jmx-console.  QueueDepth increases everytime I send a message.

Basically, the problem was that MDB wasn't being invoked when a message is
sent to the queue.  The client code was sending a message to a queue called
"queue/EmailQueue" and the EmailManagerMDB was configured to listen to
"queue/EmailQueue" in the jboss.xml file.  I have included both jboss.xml
and ejb-jar.xml files at the end of this email.  I also have includes both
MDB and the client code.

Here is the dillema.  The way I made the MDB gets invoked was that I changed
the client code to send the message to "queue/EmailManagerMDB" not
"queue/EmailQueue".  Now, my state of confusion starts.  First, when I
deployed the MDB, I got some strange message from the console saying,
"[JMSContainerInvoker] destination not found: queue/EmailManagerMDB reason:
javax.naming.NameNotFoundException: EmailManagerMDB not bound
 [JMSContainerInvoker] creating a new temporary destination:
queue/EmailManagerMDB"  I don't understand why I get this message.  In the
jbossmq-destinations-service.xml, I have added following queue entry.

  
	 name="jboss.mq.destination:service=Queue,name=EmailQueue">

optional-attribute-name="DestinationManager">jboss.mq:service=DestinationMan
ager
  
.

Why does JMSContainerInvoker creates this temporary queue when it was
configured to listen to "queue/EmailQueue".  I thought that MDB listens to a
queue and it's onMessage method gets called when a messages get inserted
into the queue!

Am I wrong?

Thanks in advance.

Re: [JBoss-user] help clearing a single user from authentication cache

[David Ward]

Thanks, Scott.  I noticed you assigned yourself to the RFE I submitted 
for this.

Just curious - by "next release" do you mean 3.0.7 or when 3.2 goes final?

Also, we tried implementing our own CachePolicy, but had trouble since 
it didn't seem like the CachePolicy interface had all the information it 
needed to know to make the decision to clear a particular user, and 
when.  Anyway, if there's going to be a jboss-3.0.7_tomcat-4.1.18 soon 
that includes the new JaasSecurityManager method, I'm happy enough to 
wait for that.

Thanks again,
David

I'm trying to clear from the authentication cache JUST a single user.
Invoking flushAuthenticationCache(String) on the mbean works fine, but
it flushes *all* users' security infos.

I want to call the CachePolicy's remove(Principal) method, so I tried
looking up the CachePolicy in JNDI and calling it.  Though I found a
TimedCachePolicy in jndi under java:/timedCacheFactory/docs (docs is our

successfully, it doesn't seem to do anything.

Then, I tried extending JaasSecurityManagerService, configuring the use
of my class in jboss-service.xml.  I see it in the JMX-Console, but for
some reason my added method isn't showing up there (under list mbean
operations), and I don't know how to register an MBean interface to
expose it.

Please help.  Again, my end goal is to flush the authentication cache
for just a single user.  Unfortunately, there's not a public, exposed
method in the JaasSecurityManagerService that does this.

Also, below is some output from the jmx console JNDIView.

Using JDK 1.4.1_01, jboss-3.0.4_tomca-tomcat-4.1.2 on Linux.

I'm trying to clear from the authentication cache JUST a single user. 
Invoking flushAuthenticationCache(String) on the mbean works fine, but 
it flushes *all* users' security infos.

I want to call the CachePolicy's remove(Principal) method, so I tried 
looking up the CachePolicy in JNDI and calling it.  Though I found a 
TimedCachePolicy in jndi under java:/timedCacheFactory/docs (docs is our 
app's security name), and called the remove(Principal) method 
successfully, it doesn't seem to do anything.

Then, I tried extending JaasSecurityManagerService, configuring the use 
of my class in jboss-service.xml.  I see it in the JMX-Console, but for 
some reason my added method isn't showing up there (under list mbean 
operations), and I don't know how to register an MBean interface to 
expose it.

Please help.  Again, my end goal is to flush the authentication cache 
for just a single user.  Unfortunately, there's not a public, exposed 
method in the JaasSecurityManagerService that does this.

Also, below is some output from the jmx console JNDIView.

- What's up with the "Failed to lookup: timedCacheFactory?"

- When I looked up the timedCacheFactory, it's actually a $Proxy class 
(EJB?)

- java:jaas/docs says it's a SecurityDomainContext below, but when I 
look it up in code, I get a ClassCastException saying it's *really* a 
JaasSecurityManager!  Why the descrepency?  If it *was* actually a 
SecurityDomainContext, I could call 
sdc.getAuthenticationCache().remove(new SimplePrincipal("username"))!

Thanks again,
David

Re: [JBoss-user] Can two separate client threads make simultaneouscalls?

[David Ward]

Are you hitting a Stateful Session Bean or a Stateless one?  According 
to the EBJ spec, it is illegal to hit a transactional Stateful one from 
two threads simultaneously that have the same bean handle.

David

Beau Cronin escribió::
I have a Swing app which is essentially single-threaded, accessing the 
server in the usual way through a session facade.  I'd like to do some 
background loading of certain data for performance reasons, but when I 
try to do this by using a separate thread (and separate session 
instance), I get various transaction collision problems if these two 
threads access the server at the same time.

I'm obviously missing something here--shouldn't different remote client 
threads from the same client be able to access JBoss simultaneously in 
the same way that entirely different clients can?  I.e., shouldn't they 
spawn separate transactions which are scheduled appropriately by JBoss?

Any clarification appreciated,

Re: [JBoss-user] Could not enlist in transaction on entering meta-awareobject

[David Ward]

Igor, thanks for your help.  My code has many places where a SLSB puts 
data into a DB, all with Transaction set as Required.

My app is basically like this (sorry for the ASCII art):

  HttpServletRequest
 |
 V
HttpServlet
- Look up and start UserTransaction
- Translate and hand-off call to SLSB
 |
 V
Stateless SessionBean (TX=Required)
- Delegates work to Application processors
 |
 V
Application processors
- Some might do JDBC via DataSource; - Some might use CMP
|  |
|  |
V  V
Custom JDBC  CMP EntityBeans (TX=Required)

 V
HttpServlet (Flow returns)
- If no errors, commit UserTransaction
- If errors, rollback UserTransaction


The JDBC work delegated to the application processors uses the same 
JNDI-looked-up DataSource as the CMP Entity Beans are configured to use. 
 We also have a custom login module that uses the same JNDI looked up 
DataSource.

I will create a small test case as you mentioned.  I just thought that 
describing how my app is set up might spark some thoughts from you or 
others though while I'm doing that.

I've used earlier version of JBoss (2.4.x) that do all of the above 
fine.  Of course, that was with Oracle 8i + classes12.zip instead of 9i 
+ ojdbc14.jar, and using jdk 1.3.1 instead of jdk 1.4.1.

Thanks again,
David

Re: [JBoss-user] Could not enlist in transaction on entering meta-aware object

[David Ward]

Thanks for the response, Manoj.  I have answered your questions below:

Sasidharan, Manoj escribió::

Here are my few cents:

1. Try re-starting JBoss and see if it helps


Tried.  Doesn't help.


2. Have you run the Oracle JVM initialisation SQLs on the database.. This is
required for using XA with Oracle. There is a script/sql to verify whether
this is installed fine.


I have run initjvm.sql and initxa.sql.  Anything else I need to run? 
Which script is the verifier you've mentioned?

3. Oracle provides separate JDBC drivers for use with JDK 1.4, can you try
using this too.


I am using the latest ojdbc14.jar.

Thanks again,
David

3.2.0RC1
Date: Thu, 16 Jan 2003 10:09:32 -0500

I'm using jboss-3.2.0RC1_tomcat-4.1.18 with Sun JDK 1.4.1_01 on 
Mandrake 9.0 Linux 2.4.19-16, with half a gig of RAM and an 800mghz 
i686 cpu.

I've noticed that on JBoss startup (using the default server), this 
line takes upwards of ** 15 seconds **:

10:13:24,288 INFO  [SARDeployer] looking for nested deployments in :
file:/home/david/data/packages/jboss/3.2.0RC1_tomcat-4.1.18/server/default/deploy/jbossmq-service.xml 


Why so long?  On jboss-3.0.4_tomcat-4.1.12, it just flew by with 
everything else.

I use the jbossmq-service.xml file out-of-the-box.  I notice there are 
differences between the 3.0.4 and 3.2.0RC1 versions of this file, but 
that's how they came - I didn't touch them.

I do tweak the jbossmq-destintations-service.xml file, but diffing my 
3.0.4 and 3.2.0RC1 versions show only one difference: the date comment 
at the top of the file.

Any ideas?

Yes, you need to set Pad=true.



3) Is there any other file I have to touch?


No.

[JBoss-user] oracle-xa-ds.xml vs. oracle-xa-service.xml

[David Ward]

The oracle-xa-service.xml file seems like the old 3.0 style...

1) Do we need it?  Can we just use oracle-xa-ds.xml?

2) If I just use oracle-xa-ds.xml, do I still need to use the "Pad" true 
for the XidFactory in transaction-service.xml?

3) Is there any other file I have to touch?

Has anyone here used hibernate in preference to cmp? If so how has it worked
out for you in jboss? We are considering it or cmp. Hibernate certainly
seems more flexible, but I was thinking it doesn't abstract the app from the
data as much as cmp forces you to.

Our application has fairly straightforward tables and relations, typical
ecommerce type data, no big transaction concerns. I guess my main question
is this, is hibernate better, or does it come down to just a different
method than cmp (ie a strong argument for using a standard api vs
hibernate).

[JBoss-user] DataSource or XADataSource: autocommit problem

[David Ward]

Using jboss-3.0.4_tomcat-4.1.12, JDK 1.4.1_01 on W2K, Linux, Solaris 9, 
hitting Oracle 9.2.0.1.0...

We have an app where all traffic goes through a single Servlet that 
wraps all application calls in a UserTransaction gotten from JNDI.  All 
database work gets done through a single DataSource mapped in JNDI, but 
unforunately some of that jdbc work is done in CMP's, some in SLSB, and 
some (gasp) in JSP's.  There is only one app server hitting one 
database, and we are using the latest ojdbc.jar (using thin) from Oracle.

My first question is, given the above scenario, do I have to use an 
XADataSource or is DataSource sufficient?  We have upgraded our 
architecture from JBoss 2.4.7 to 3.0.4, and in 2.4.7 we used 
XADataSource, though granted with the (I think Minerva?) wrapper.  We 
also had to configure to use Oracle's Xid class, not sure if that's 
necessary now or not.

My second question is, if we need to use an XADataSource, does 
oracle-xa-service.xml work in JBoss 3.0.4?  I think I remember seeing 
some questionable threads on this list about it.

The problem we're seeing now is that even though we're using a single 
UserTransaction around everything, it doesn't matter since Connections 
are being retured from the DataSource with autocommit ON, and stuff is 
being committed in the database before the UserTransaction commits it. 
I'm assuming this is because we're not using an XADataSource, but could 
I get by with a regular DataSource, but configure the oracle-service.xml 
somehow to hand out Connections with autocommit off?  Trying to turn 
autocommit off programatically throws an Exception since the server 
realizes we're using a UserTransaction.

Thanks for all your help,
David

You say that like it's so easy Scott...  ;)  Seriously, what is Oracle

Anyway, if you are going to indeed write your own jca adapter, instead 
of starting from scratch here is a possible place to start.  Granted, 
there is nothing in the code that has anything to do with the JCA spec, 
but it points out some stuff you will need to keep in mind when you

Re: [JBoss-user] Store large pdfs with JBoss

[David Ward]

I have been able to put CLOBs and BLOBs into Oracle 9i using JBoss 
3.0.4, though admittedly after jumping through several hoops.

1) yes, ejb's aren't supposed to do i/o - I do my work delegated from 
the servlet level.

2) You have to have autocommit off.  For some reason autocommit is on by 
default in JBoss 3 (wasn't in 2.4) from Connections from DataSources. 
Please someone tell me how to turn this off in a global config somewhere!

3) You have to first insert a row using an empty lob.  For example,
insert into my_table (key, data) values ('1', empty_blob())
.  You could have used empty_clob() if you were using CLOBS instead of 
BLOBS.

4) You can then update the BLOB, hower you have to re-select *** using 
select for update ***.  If you don't use select for update, ** it won't 
work **.  For example,
select data from my_table where key = '1' for update

5) You then can update the BLOB from the ResultSet.  Notice I said 
oracle.sql.BLOB not java.sql.Blob. I had to use an Oracle-specific type 
here.  I couldn't get it to work any other way, and I spent hours (no, 
setBinaryStream does not work)...  For example,
BLOB blob = (BLOB)rs.getBlob(1);
BufferedOutputStream bos =
new BufferedOutputStream( blob.getBinaryOutputStream() );
// write to the output stream
// safely close everything up

6) Don't forget to commit the work you did.  This will commit the insert 
and the data your wrote to your BLOB.

7) I set the autocommit on the Connection back to what it was when I 
first got it from the DataSource, before I close it (the Connection, 
which returns it to the pool).  Again, I'd like to see autocommit off 
since I wrap everything in a UserTransaction and it should be committed 
there instead...

Hope this will save you some of the painful time I had to go through if 
you decide to go this route.

David

Scott,

Thank you for your prompt reply.  Can you point me to some docs/examples 
of how to configure security caching and implementing my own security 
cache policy for 3.0 (and maybe also 2.4)?  I looked through 
JBossBook_304.pdf and nothing jumped out at me.

Thanks again,

This is the expected behavior due to caching. If caching is enabled then
a given login module stack is not executed unless the cache credentials are

[JBoss-user] LoginModule methods not always being called on login

[David Ward]

Hello, all - we've got an issue where interface methods of our custom 
login module are not being called after a first successful login.  Our 
guess is somewhere in the security info caching.  We see it in both 
JBoss-2.4.7_Tomcat-3.2.3 and jboss-3.0.3_tomcat-4.1.12 on W2K, Linux, 
Solaris, using JDK 1.3.1 and JDK 1.4.1.  We are using form-based 
authentication, per J2EE spec.

When a user is authenticated the first time (successfully), the login() 
and commit() methods of our custom LoginModule are called and all is 
well.  The second time the user logs in (successfully), he is 
automatically logged in, however, login() and commit() are not being called.

We have custom code in login() and commit() that always need to called 
during a login.  If we clear the jboss security authentication cache 
between logins, the methods get called again, however this solution is 
undesireable since it clears all the roles for other users also and 
causes us to have to query the database for the roles again.

Here are the 3.0 config files associated with the login module:

jboss-web.xml:
  
java:/jaas/docs
...
  

web.xml:
  
FORM
WebDOCS

  /login.jsp
  /authenticationError.jsp

  

login-config.xml:
  

  
flag = "required">
java:/DocsDS
  

  

Here are the 2.4 config files:

auth.conf:
  // The docs login module
  docs {
org.jboss.security.auth.spi.ProxyLoginModule required
moduleName=corp.docs.security.DOCSLoginModule
dsJndiName="java:/DocsDS";
  };

jboss.jcml:
  
  

="SecurityManagerClassName">org.jboss.security.plugins.JaasSecurityManager

="LoginConfig">Security:name=DefaultLoginConfig
  
  
="Security:name=DefaultLoginConfig">
auth.conf
  

web.xml:
  
FORM

  /login.jsp
  /authenticationError.jsp

  

jboss-xml:
  
java:/jaas/docs
...
  

Has anyone else seen this?  Is there a way to configure jboss to always 
call all methods on the custom LoginModule during a login, but cache

Re: [JBoss-user] Accessing EJB remotely

[David Ward]

Weber,

You need to use the GLOBAL jndi name for your bean from remote clients. 
 JBoss has yet to support remote clients using the env/ejb context.
Change your xdoclet ejb.bean tag to have both jndi-name and 
local-jndi-name attributes (and view-type="both").  Use the 
local-jndi-name when code runs in the same vm as jboss and use the local 
interface, with NO PortableRemoteObject.  For remote clients, use the 
jndi-name WITH PortableRemoteObject and the remote interface.

Hope this helps,
David

Hi folks,

as you will notice, i'm a newbie to JBoss. My doubt is about how to
access an EJB remotely.

The first thing i did was trying to access the EJB from a local client
application. So far, so good. The client ran smoothly and i thought that
was pretty much all there was to it. Nevertheless, every time i try to
run the same client application remotely, it crashes because the lookup
call on the InitialContext instance always returns null.

As far as i can see, its a problem on the absolute path of the context
i'm passing to the lookup method. The EJB is being deployed correctly
and the client application finds and connects to the server, as shown in
the following tcpdump output:

Re: [JBoss-user] Fastest (and stable) way to turn existing EJBs into Web Services?

[David Ward]

If you make sure your value objects adhere to the javabean spec, you can 
use Axis' custom BeanSerializer and BeanDeserializer to automatically 
encode/decode them for you.  I do this and it works fine.  Initially the 
cvs version of xdoclet (1.2) was not making "true" javabeans for the 
value objects, but I submitted a patch that has long since been applied 
that fixes that.  As for the WSDL, adding "?WSDL" to your service URL 
creates it for you dynamically with JBoss.net/Axis.  Granted, I haven't 
tested this with a .net client yet...

not basic data types. Also the client is a ".net" client and not a plain

I've been looking for a product that can do the above 2 things, ie (1)

Depends on which JBoss version you want to use and which Web Service
requirements you have.



1) Use JBoss with Axis (what version?)
2) Use JBoss.net (what version?)



JBoss.net really is Axis with a bit of comfortability around. I will have
backported the JBoss4(head)+Axis1(release) combo into
JBoss3.2(beta)+Axis1(release) by the end of this year. If 

- that stability is what you are content with and 
- you stick pretty much with the "SLSB as Web Service, JavaBean as
XML-Structures" approach and
- you are satisfied with http-auth security and
- you do not want sophisticated XML-registry support

I guess that jboss.net could be your choice, especially since the xdoclet
task makes it very easy to build. We will also care about smoothly migrating
to the J2EE1.4 spec from the web service archive design.


3) Use 3rd party tools like GLUE.



I have no experience with it. But they make a good and advanced impression
(which they should for the money ;-), nevertheless seems to be somewhat
proprietary.

What about Altoweb?

No experience (havent tested it) but Apache will only slow you down as you

Be careful of one-size-fits all suggestions.  I do have experience, and 
whether it helps or hurts depends on your situation.

Even if all your pages are dynamic, if you have a bunch of static images 
it often helps to have Apache serve them up.  Also for security reasons, 
many people put Apache in the DMZ, and have JBoss/Tomcat on a server 
behind the firewall next to their database box.  The only allowed port 
through the firewall is for the mod_jk communication, and allowed only 
from one (or a specific list if you've got more than one Apache box) IP 
address.  Lastly, I do usually maintain that the web container (Tomcat) 
co-exist in the same JVM process as the EJB container (JBoss) so you can 
avoid serialization and use local interfaces (allowing pass-by-reference).

In the end, you should do your own performance testing, and weigh it 
against your security needs, your configuration tolerance, and last but 
not least, your budget.

reasons initially), or is it the thead that carries the reference to 
the transaction (context)?  If it's the later, that's when I suggested 
that InheritableThreadLocal could come into service.  Each spawned 
thread could still access the tx from the InheritableThreadLocal.  If 
it's the prior, then I'll have learned something and retract with my 
tail between my legs - no problem.


I think you would have a very difficult time building a transaction 
manager that could allow multiple threads in a single transaction.  Just 
to start with, you would have a huge problem with serialized isolation.  
Then you would have a big problem with connectors as everyone assumes 
you only have one thread in a tx at a time (this is a huge step forward 
from the days when you could only have a single thread per tx and it 
always had to be the same one... old junk).

Anything is possible, but is it worth it, when you can get 95% of the 
need from a JMS queue and new transactions?

David,

Read this:
http://www2.theserverside.com/resources/articles/MonsonHaefel-Column3/article.html
(this is the 2nd article - the first one talks about endpoint interfaces).

In the 2nd article, take a look at the "Introduction" and the "JAXM" 
sections for one person's possible explanation.

Now, here's the weird part: If you look at ejb-2_1-prd-spec.pdf (from 
Sun), they still have a couple places in the spec where they do mention 
JAXM message-driven beans.  For example, like this:

"The message-driven bean class's implementation of the 
javax.xml.messaging.OnewayListener or 
javax.xml.messaging.ReqRespListener interface distinguishes the 
message-driven bean as a JAXM message-driven bean."

Do a search in the spec for JAXM and you'll see them.  *However*, it 
seems like these were just places that Sun forgot to remove the text, 
because they *were* going to support them?  However, nowhere in the spec 
do I see any examples of using JAXM message-driven beans, only JMS.  No 
figures, no XML examples, no code, no nothing!

Maybe I'm just missing something here.  Either they did a poor job 
cleaning out the document when they decided not to support it, or they 
are supporting it but were lazy filling out the spec with figures, 
examples and code...

Can anyone else clear this up?

Thanks,
David

I don't get this excerpt:

"JBoss will not be a complete implementation of J2EE 1.4, though. Fleury 
said APIs for XML-based Web services were excluded because of a lack of 
demand. The APIs will be included should that change, he said."

JBoss 3.0.x+ includes Apache AXIS integration... isn't that most of the 
way there (to web services)?  Correct me if I'm wrong, but since it 
appears that JAXM based Message Driven Beans isn't going to make it in 
EJB 2.1, the only thing left is JAXR endpoint interfaces to SLSB's (and 
resource factories to external web services).  If JBoss re-aligns the 
.wsr archive stuff to accomodate SLSB endpoints, why exclude it?

BTW, I'm assuming J2EE 1.4 support is what JBoss 4 stuff is targeted 
for, right?

JBoss Elite!

I have tried any number of ways to get the JBoss-3.0.4/Tomcat
4.1.12-LE-jdk14 Integrated bundle to serve up a simple jsp/servlet web
application.  Each of the approaches has been unsuccessful. The deployed
JSP works, but the called servlet does not.  I have successfully taken
the example.war file and copied it into my standalone tomcat and it
worked. I have installed the JBoss-3.0.4 with JBossWeb (Jetty) and
deployed the example.war and had it work.  Could someone please take a
look at the included .war file and my steps and tell me what I did
wrong?

Thanks,

Will


Here's the readme that I created...

1. Create the following 4 directories wherever you like:
	1. example
	2. example\src
	3. example\web
	4. example\descriptors

2. Cut and paste the contents of the following 5 files saving them in the
appropriate directories - the content is at the bottom of this file:
	1. example\build.xml
	2. example\descriptors\application.xml
	3. example\descriptors\web.xml
	4. example\src\HelloWorld.java
	5. example\web\index.jsp

3. Open a command prompt in the example directory and type:
	ant
	
	note: you might have to set the classpath for the servlet.jar, ie. set 
	classpath=D:\jboss-3.0.4\tomcat-4.1.x\common\lib\servlet.jar
	before calling ant if it complains.

4. Should have had no errors and created a build directory with the structure:
build\deploy
build\descriptors
build\ear
build\ear\META-INF
build\src
build\war
build\war\WEB-INF
build\war\WEB-INF\classes

5. To deploy the Web Application on Tomcat, simply copy the file:
build\deploy\example.war
into the %TOMCAT_HOME%\webapps directory

5a. To deploy the Web Application on JBoss, simply copy the file: 
build\deploy\example.war into the jboss-3.0.4\server\default\deploy 
directory.

6. To test the deployment of the JSP browse to: 
http://localhost:8080/example/index.jsp

7. To test the deployment of the Servlet, browse to:
http://localhost:8080/example/index.jsp
and click the hyperlink:
Click here to execute the Servlet 

or browse to:
http://localhost:8080/example/servlet/HelloWorld

8. Good job and well done! (Cry if it's JBoss + Tomcat)

Scott,

Worked like a charm.  Thanks muchly.

Others:

For the tomcat bundle, the attribute goes in this file:

/opt/jboss/server/default/deploy/tomcat41-service.xml

here:


	name="jboss.web:service=EmbeddedCatalina41">
...
	false
...


I don't know where to do it for Jetty.  I tried putting it in 
deploy/jbossweb.sar/META-INF/jboss-service.xml under the JettyService 
mbean, but I got a DeploymentException "No Attribute found with name: 
DeleteWorkDirs."  Where should it go for Jetty?

Thanks again,
David

Subject: [JBoss-user] how to not blow away work dir on undeploy?



Hello, all.

My env:
jboss-3.0.3_tomcat-4.1.12
Sun JDK 1.4.1_01
Linux 2.4.19-16mdk, Mandrake 9.0, i686
Apache 2.0.43 w/JK2.0.2->Coyote

When I was using jboss-3.0.3_tomcat-4.1.12, undeployment of my app 
caused a stack trace in the jboss server console.  That seems to be 
fixed in jboss-3.0.4_tomcat-4.1.12, BUT I"ve got a new problem: The 
undeploy blows away my tomcat work directory!

To be more specific, actions of redeploy/undeploy/shutdown all make this 
directory:
/opt/jboss/tomcat-4.1.x/work/MainEngine/localhost/MyAppDir
get blown away.

The side effect of this means that whenever I re(hot)deploy my app, all 
my JSPs have to recompile all over again, even if they haven't changed. 
 This absolutely kills iterative development by increasing 
redeployment/retest time drastically.

Is there someway I can disable this behavior?  I've used JBoss for a 
LONG time (many versions of it), and this is the first version I've seen 
that blows away the web container's already-compiled JSPs.  I'm just 
fine with this happening on a production server - but not when I'm 
trying to develop.

I haven't seen if this happens with the latest Jetty bundle, but I'm 
guessing it does... See the very recent email on this list by Todd Benge 
"Change Jetty Deployment Dir" - he says "...and also instruct Jetty not 
to clean the directory on undeployment?"

Thanks for any and all help,
David

Re: [JBoss-user] Howto get server/container (real) name/id ? request.getServerName()does not...

[David Ward]

Joao,

Because IP_LIB fronts the actual servers, it is correct behavior that 
request.getServerName() returns IP_LIB.  This way, you can use the 
request to build URLs to forward with that the client will actually be 
able to access.

Now, if you want to know the *actual* server the app is running on, do 
not use the Servlet API.  Use java.net.InetAddress.  It has many helpful 
methods.  The specific one you are looking for is this:

java.net.InetAddress.getLocalHost().getHostName().

Note that in JDK1.4 there are a lot more methods added, and also two new 
subclasses (Inet4Address and Inet6Address) that you might find useful.

Hope this helps,
David

If i use a "request.getServerName()" I always get IP_LB as the answer

maybe jboss api has it?

Re: [JBoss-user] Same deployment unit?

[David Ward]

Serlvet goes in war, EJB in jar.  Servlet can use local interface to ejb 
since war and jar both in an ear (the "same deployment unit").

A Servlet can *not* use a local interface of an ejb that's on a 
different app server.  That would, by definition, imply "remote."

You can find out the nitty-gritty details by reading the J2EE, EJB, and 
Servlet specs.

Hope this helps,
David

SainTiss wrote:
Hi,

I've read that a servlet for example could have access to an EJB's local
interface, if the servlet is in the same deployment unit as the EJB...

Does this mean it has to be on the same application server? Or does this
mean it's got to be in the same jar? 

In the second case there seems to be a problem, since servlets seem to
go in war files and EJB's in jar files...

Thanks

Does anybody know why public void valueUnbound(HttpSessionBindingEvent) 
isn't being called on objects stored in an HttpSession with a hot 
redeploy or shutdown/startup of jboss with jboss-3.0.3_tomcat-4.1.12?

It's causing us major problems as we need that hook.  I'm guessing it's 
related to this:
http://www.mail-archive.com/jboss-user@lists.sourceforge.net/msg5.html

Does anyone think this is related to the stack trace on web app undeploy 
that was broken in 3.0.3 but supposedly fixed in jboss-3.0.4-tomcat_4.1.2?
http://sourceforge.net/project/shownotes.php?release_id=120145
See see the Jett/Tomcat comment:
"# comments: Obtain the working dir from the context before removing the

Re: [JBoss-user] configuring security if web and ejbs on differentmachines

[David Ward]

Good point.  Now you're introducing a more clustered approach.  It 
really depends on what his needs are - and from the sounds of it the 
performance requirements don't seem very well known.  I didn't know if 
he wanted to go that far.

When it comes to applications, I usually warn people not to invent a 
perceived performance problem.  Often times people go overboard and 
their design suffers from something that "might be" when there is no 
data to support it.  I say, design for best design, but test early and 
often so if you do need to modify the design for performance reasons 
you're not too far down a certain path.

Feel free to run your own performance tests (always run your own tests

cummulative wisdom and experience that exists on this list (it's very 
significant here) as a good starting point.

Generaly speaking, the advice I gave you (supported by others' 
comments) holds true in most circumstances.  If you've got an extra 
box laying around, then cannibalize the CPU and RAM out of it and 
stick it into your main box.

Also know that serialization is not the only issue.  If you split the 
boxes up, you've *also* introduced network latency between the two, 
other RPC/RMI issues, and quite possibly more container 
interceptors/invokers that need to get involved (not positive about 
this one, others on this list could verify).

Whether or not (or how) you explain it to your customer(s) is up to 
you.  Mostly what we suggested has become the domain of common 
knowledge, but if you need to back it with hard numbers either do some 
searching online, ask people on this list if they've run some tests 
that they could share with you, or - last but not least - run the 
tests yourself.

Have fun,

What *I* don't understand is why you think having your web container 
on one machine and your ejb's on another would perform better.  
Having your servlets run in the same JVM as your ejb's allows your 
servlets to access them with local interfaces, and you can pass your 
objects by reference instead of by value (read: serialization 
unecessary).  You will get much better performance if everything is 
in the same JVM.  Just beef up your box instead of spending $$$ on two.

Now, if you want to have Apache serve up some static content and 
front your app, that's fine (especially if for security reasons you 
want your app server behind a firewall and your web server in the 
dmz).  However, it will forward dynamic requests to your app server 
- where your web container and ejb tier coexist in the same process.

Re: [JBoss-user] configuring security if web and ejbs on differentmachines

[David Ward]

Pavel,

Feel free to run your own performance tests (always run your own tests 
since applications and configurations differ), however leverage the 
cummulative wisdom and experience that exists on this list (it's very 
significant here) as a good starting point.

Generaly speaking, the advice I gave you (supported by others' comments) 
holds true in most circumstances.  If you've got an extra box laying 
around, then cannibalize the CPU and RAM out of it and stick it into 
your main box.

Also know that serialization is not the only issue.  If you split the 
boxes up, you've *also* introduced network latency between the two, 
other RPC/RMI issues, and quite possibly more container 
interceptors/invokers that need to get involved (not positive about this 
one, others on this list could verify).

Whether or not (or how) you explain it to your customer(s) is up to you. 
 Mostly what we suggested has become the domain of common knowledge, 
but if you need to back it with hard numbers either do some searching 
online, ask people on this list if they've run some tests that they 
could share with you, or - last but not least - run the tests yourself.

Have fun,
David

OK, thanks for you response, I understand your point.

But what should I do, if there's a need for better perfomance
and customer says "well, I could buy another CPU or more RAM, but
I have also an extra unused machine here - couldn't we use it
instead of buying new CPU or RAM?" Should I try to explaint him
it's not a good idea?

I thought splitting my app between two machines should also give
me a significant performance even though the serialization overhead, 
shouldn't it?

[JBoss-user] connections autocomitting?

[David Ward]

Hello, all - seeing some weird behavior since we upgraded from JBoss 
2.4.7 to 3.0.3.  I have attached our old jboss.jcml and our new 
oracle-servic.xml to this email, and have included full environment 
listings at the bottom of this email.

Our application has a servlet in the web tier that calls a SLSB that 
delegates to a chain of other "processor" classes that do database work 
using a Connection gotten from a DataSource.  Each processor in the 
chain shares the same Connection as it gets passed from processor to 
processor.  The servlet is the one that wraps all work in a 
UserTransaction gotten from JNDI.  The SLSB is marked as tx Required. 
If any of the processors throw any kind of Throwable, it bubbles back up 
to the servlet who makes sure the UserTransaction gets rolled back, 
otherwise it (the servlet) commits it.

Now, in our old environment, if processor A (in the chain) put data in 
the database, but the next processor B throws an exception, everthing 
(including that data put in by A) got rolled back.  However, in our new 
environment, it looks like the data put in by processor A is getting 
committed, even if B throws an Exception and the Servlet rolls back the 
UserTransaction.  The only way I can see this happening is if the 
Connection is auto-committing...

Does anyone think this is a change of defaults Oracle made between their 
old and new JDBC drivers?  How can I configure oracle-service.xml such 
that Connections are handed out from the DataSource as auto-commit false 
(I'd rather not do it programatically)?  Is there any other reason this 
could be happening?

One last thought I had is that in our old config, we specified the class 
as an XADataSource, but in the new version, just DataSource (we did not 
use the example oracle-xa-service.xml example).  I did this because I 
thought the XADataSources were only necessary when a transaction needs 
to span multiple JVMs or systems.  Is this not true?

Thanks muchly for all your help/input,
David

Thanks,

Derek,

JBoss 2.4 and 3.0 come with easy ways to connect with a mail server:

2.4: $JBOSS_HOME/conf/default/mail.properties
3.0: $JBOSS_HOME/server/default/deploy/mail-service.xml

You can then look up in JNDI (java:Mail, for example) and use the 
JavaMail API.

As far as bundling an actual java mail server, I'm not sure - but I tend 
to doubt it.  It probably wouldn't be too hard to write an MBean (if one 
doesn't already exist) around James - http://jakarta.apache.org/james/ - 
 and hot-deploy it in JBoss, but I've never used it so I don't know.

If you are deploying your app at at even a small-sized company, they 
probably already have a mail server running you can connect to...

Hope this helps,
David

Re: [JBoss-user] JBoss on Solaris?

[David Ward]

This could be it, or it could be that there is a process already bound
to the port, thus the conflict.  You could use netstat or something
similar to figure this out.

As an aside, I would suggest that you don't run JBoss as root.  Instead,
have a start-up script (that would work in /etc/init.d) that runs as
root but su -c 's to a jboss (or whoever) user.  That way, the process
can bind to lower ports, but the process (java/jboss) runs as the other
user.  Also, your "jboss" user should have minimal rights on the system
in case 1) someone compromises the system or 2) rogue code accidently
tries to delete directories (ie: system files) it shouldn't.

And oh yeah - make sure you nohup the su -c 'd process also.  That way
disconnecting your terminal won't signal your process to shut down.

Just my 2 (or maybe 3) cents -
David

[JBoss-user] jsp->javac logging in jboss-3.0.3_tomcat-4.1.12

I am using:
Red Hat Linux 7.1.
Sun JDK 1.4.1
jboss-3.0.3_tomcat-4.1.12

I have attached my log4j.xml and tomcat41-service.xml files.

Obviously, I could change my ConsoleAppender's Threshold to ERROR (from 
INFO), but then it cuts out a lot of logging that I want (app's 
deploying, services starting, etc.).

Limiting the org.apache.jk category to ERROR helped me get rid of all 
the coyote/jk2/ajp13 chunk data, so I tried limiting the 
org.apache.jasper category too, but to no avail.  Maybe something in 
org.jboss.web.catalina?  But what?

Thanks for any and all help!

Sincerly,

[JBoss-user] but I don't want SESSIONS.ser

[David Ward]

Hi, all.  I am using jdk1.4.1 with jboss3.0.3_tomcat-4.1.12.  I am 
trying to get tomcat to NOT save a 
/opt/jboss/tomcat-4.1.x/work/MainEngine/localhost/myapp/SESSIONS.ser 
file when I stop jboss or redeploy my app.

I tried putting a  element in my tomcat41-service.xml file 
underneathe the DefaultContext element, and tried not setting the 
pathname attribute (the tomcat source says a null value of this for the 
StandardManager implementation will mean no file will be written), and 
tried setting it to an empty string, but to no avail.

I do not have the  element in my web.xml, as it is still 
using servlet spec 2.2, not 2.3.

Any help?

Thanks,
David

[JBoss-user] servletContext.getRealPath(String) always null w/JBoss3 + Tomcat4.1

[David Ward]

I am porting a JBoss 2.4.x + bundled Tomcat 3.2.3 / JDK 1.3.0_02 .ear 
app to JBoss 3.0.3 + bundled Tomcat 4.1.12 / JDK 1.4.1.

In the past, I had no problem calling servletContext.getRealPath(String) 
and it returning something as my previous bundle always unpacked the 
.war file that was in the .ear file.  However, with this newest bundle, 
getRealPath(String) *always* returns null.  I tried changing 
tomcat41-service.xml's  element to contain an unpackWARs="true" 
attribute, but that didn't help.  JBoss 3.0.3 + bundled Jetty doesn't 
seem to have this problem.

Can anyone help me figure out how to force tomcat to unpack the war that 
was in my ear?

Thanks,
David

Re: [JBoss-user] CMR Problem: Chicken and Egg

[David Ward]

Currently in JBoss, you have to have your cmr foreign keys nullable 
since they can only be set in ejbPostCreate().  From what I understand, 
Dain Sundstrom ("the" JBossCMP guy) is very aware of this and is looking 
at supporting setting cmrs in ejbCreate() (so you can have NOT NULL 
foreign keys) in a not-to-distant future version.  Dain, please correct 
me if I'm wrong.

[JBoss-user] JBoss/Jetty: Realm Not Configured

[David Ward]

I have an app that works great with jboss-2.4.3_tomcat-3.2.3, but I 
can't get it to work with jboss-3.0.3 (w/ integrated Jetty).  It has a 
secure area that when I access it via a web browser, I get:

HTTP ERROR: 500 Realm Not Configured
RequestURI=/docs/sweb/david_cust/david_site/PrintItSimple

Again, this worked in jboss-2.4.3_tomcat-3.2.3, though of course the 
config files are slightly different now.

login-config.xml:


   
 
 corp.docs.security.DOCSLoginModule
 java:/DocsDS
   


DOCSLoginModule.class is in a jar file in server/default/lib/.

jboss-web.xml:

java:/jaas/docs

web.xml:


   
 Secure WebDOCS
 /sweb/*
   
   
 DEFAULT
   


Non secure areas of the app work fine.

Thanks for the help,
David

Re: [JBoss-user] JBOSS on solaris

[David Ward]

None to worry about.  I do notice that large .*ar extraction takes a bit 
longer when deploying than it does on, say, a Linux box - or even on a 
non-fragmented Windoze box.

[JBoss-user] Realm Not Configured

[David Ward]

I have an app that works fine in jboss-2.4.7_tomcat-3.2.3, and am trying 
  to use it in jboss 3.0.3 (w/integrated jetty).  I can surf the app 
until I try to reach a protected area (config'd in web.xml), at which 
point I get this error in my browser (instead of the intended login.jsp 
page):

HTTP ERROR: 500 Realm Not Configured
RequestURI=/docs/sweb/david_cust/david_site/PrintItLogin

Any pointers?  I'm guessing it's a configuration problem...

Thanks,
David

[JBoss-user] jboss + tomcat 4.1.12

[David Ward]

Just wondering why each new release of JBoss gets bundled with old 
branches of Tomcat (or Catalina).  For instance, tomcat 3.2.x and 
catalina 4.0.x, instead of 3.3.x and 4.1.x.  Classloading issues?  My 
guess is just strapped for time to regression test the bundles 
(understandable).  I'm sure JBoss 3.2 (and maybe even 4) is more at the 
forefront of developers' minds.

However, I'm kind of stuck in that I want to drop mod_jk (unacceptable 
performance) for the Coyote connector, but that doesn't come included 
until Catalina 4.1.  I could get it into 3.3 or 4.0, but I'd have to 
mess around with the packaging and configs.  Is there any way someone 
can release a JBoss-2.4.9_Tomcat-4.1.12.zip?  (I can't use JBoss 3.x yet 
- long story.)

Whoever can help me (Scott?), I would greatly appreciate it.  Thank you 
for your time and effort,
David

[JBoss-user] jboss reference in latest javasoft highlight

[David Ward]

Not sure if others saw this or are interested in it...

JBoss Compatibility

Q: In a recent survey, a lot of developers want to know when Sun will 
allow JBoss to be branded as compatible with Java technology.

A: Yeah, that's a really tough situation. JBoss is an open source 
project that wants to say they are compatible with J2EE, but they are 
also a for-profit project, so they can't apply for zero-cost access to 
the TCKs under the new rules. Recently JBoss launched its own 
certification program, which is interesting. Open source wisdom says 
that it's really hard to maintain a fork. It will be interesting to see 
how they do. I'd really like to see Sun and JBoss work together to find 
a solution to the problem. They got great coverage at the 2002 JavaOneSM 
conference -- several awards. It's a very popular effort.
