I believe the the default build for Apache2 on Solaris is still pre-fork, so
you should still be able to eck out a few more months with mod_webapp.
However, if you have an Apache2 that is not pre-fork, you are already dead
:).

mod_jk2 has a lot of promise, but if you need to move to production in the
very near term, I'd stick with mod_jk personally (since mod_jk2 isn't GA at
the moment).  If you have a few months horizon to move to production, then
by all means, try mod_jk2.

On Solaris, you need up-to-date versions of the GNU tools (e.g. libtool,
autoconf), and need to have the GNU make ahead of the Solaris make in the
path.  But, otherwise I've never had a problem building mod_jk(2) on
Solaris.

I am working in a windows environment.

You mean setting my environment variable %classpath% by doing SET CLASSPATH

I have done that and it still doesn't work.

RE: JDBC Realm

[Gardner, David [IT]]

Hello,

Please let me explain a little more. It is the password that the JDBC realm
uses to connect to the database that should be encrypted for example
connectionPassword="foobar" should look something like
connectionPassword="3dc69416b0783cac9f3dda37b6bb0862". I have been able to
deal with user passwords fine using MD5. We have a policy of no developer
access to production and staging environments. Thus any passwords in
configuration files such as the server.xml require encryption. However I
have since created a solution.

I have created my own class that extends
org.apache.catalina.realm.RealmBase. It works in a similar way to the tomcat
JDBCRealm. I made it available in the tomcat server classpath under
server/lib. I have configured server.xml like..

   

The connectionName="FooBar" uses a JDBC connection pool I have written that
supports password encryption. Hence I no longer have clear text passwords in
my config file server.xml.

In fact maybe this raises a point that it appears that all passwords in
config files for tomcat are clear text. For example by looking at the doco
for JNDI data sources the configs for JDBC connection pooling using DBCP
also have clear text passwords. See ..

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-how
to.html

Can you please explain this a little better.

You have in your database a list of all your user's passwords encrypted
using MD5.  Do you also have a clear text copy of them?  Then you want to
encrypt this clear text copy for use in your configuration files?

If you don't already have a cleartext copy of the passwords you are going to
have to get your users to submit them as your MD5 version is useless.  You
could amend your application to read the password, store it in the clear,
then compare it using MD5.  Then as they all log in they will have given you
a copy of their password.

Re: Form Double Submit Detection

Interesting. You store the successful tokens so they can't be used
again, and ignore the tokens that are never returned to the server. This
would be more efficient for the case where the user views but never
submits more forms than they view and do submit. I'll have to analyse my
traffic some time and see what my users are doing.

Currently I've implemented the opposite, I keep track of all the tokens
and drop those that the user returns. I also drop all tokens older than
2 hours (which means the user has 2 hours to submit any particular form
before the token goes away and they can't). (and obviously I store them
in the session so they all go away when the session does)

I like your solution better than mine.

Re: Tomcat 5 Problem with finding servlet class

[Christopher Schultz]

All,

java.lang.NoSuchMethodError: 
javax.servlet.ServletConfig.getServletName()Ljava/lang/String;


This method is not part of the servlet specification:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/servletapi/index.html
How did you compile it in the first place?
I'm sorry; I was looking at ServletContext, not ServletConfig.

Anyhow, I don't think you should be explicitly setting any classpaths 
for anything. You should just dump all your JAR files into WEB-INF/lib 
and start Tomcat without any further configuration changes.

Note that putting servlet.jar into WEB-INF/lib is a mistake. Tomcat will 
probably refuse to load thar JAR anyways, so you might be okay (I know 
it does on mine .. oops :)

Re: [OT]Virus sent to Tomcat User list.

[Jens Skripczynski]

Hi,

afaik it is a different reason.

The virus searches for valid email adresses and sends itsself to those.

So if a member is subscribed to the list, and a virus sends himself to the
list with the 'From: ' adress of a valid user it will be passed to the
members.

If he is not subscribe the message will be sent to the admin of the list for
approval.

Tomcat 5 Problem with finding servlet class

[Paresh Varatkar]

I have my jars in following manner.

webapps\gf\bin\ + 

webapps\gf\WEB-INF\lib\my jars 
webapps\gf\*.jsp, *.htmls

I can not move the jars in bin as I have no control over code and they refer /bin/path
in their code.

To make this work with Tomcat 3.2.4 I have to only set classpath before starting 
Tomcat.
I do the same with Tomcat 5 I get error which suggests that its not finding 
servlet.jar.
which is there in webapps\gf\bin\servlet.jar.

Re: Needed more support for catalina.base in Bootstrap

[Jean-Francois Arcand]

In Tomcat 5, you can customize the location of the common/lib, endorsed, 
etc.  Just take a look at $CATALINA_HOME/conf/catalina.properties. 
Double check that to see if you can do what you want :-)

Howdy,
What Steve said is right on target.  Your patch is not likely to make it
into the tomcat code base ;)
A couple of other pointers, however:
- Patches are always welcome -- so thanks for contributing ;)
- Don't attach them to messages: open a bugzilla enhancement request and
attach your patch, or better yet, a diff file from current sources to
your patch, in the bugzilla issue.
- You may wish to discuss the need for and intent of your patch on the
dev list before writing the patch itself.
- If you intend to contribute more, which I hope is the case, please
read the guidelines for getting involved with jakarta:

Subject: Re: Needed more support for catalina.base in Bootstrap
 

From: Rodrigo Ruiz <[EMAIL PROTECTED]>
   

Recently I have been trying to install and configure an OGSA server
(www.globus.org) deployed over a Tomcat container. The problem I have
   

is
   

that it requires a lot of Tomcat customization: additional connectors
   

in
   

the
 

server.conf, additional jars in the common/lib, common/endorsed and
server/lib directories, conf/web.xml modifications, and so.
In order to keep track of these changes, I decided to use a shared
   

Tomcat
   

installation, and do all the dirty business in a separated Tomcat
   

instance,
 

pointing CATALINA_BASE to it. Doing this I noticed that there was no
   

place
 

for putting my common/lib and server/lib jars.
   

This sounds backwards.  When using separate CATALINA_HOME and
CATALINA_BASE locations,
CATALINA_HOME -

the "central" location.  Classes used by tomcat (server and common
respositories) are taken from this location.  You'll also use the bin
directory for this location.
CATALINA_BASE -

the "lightweight" installations.  These contain web applications,
their own logs, own configuration files, and make use of their own
"shared" class repositories.  If you think about it, this makes
sense: separate CATALINA_BASEs can have different web applications,
so the set of web application library depencies can vary from one
CATALINA_BASE to the next.
 

Digging in the source code, I found that CATALINA_BASE is not used at
   

all
   

when building the common and catalina class loaders.
   

That's correct.  CATALINA_BASE uses the shared class loader, and
CATALINA_HOME uses common and server.

Howdy,
Since HTTP is stateless, session replication is enough for servlet
webapps to achieve clustering.  That is, session replication =
application replication.  If you're using more J2EE than servlets, e.g.
EJBs, your app server will (hopefully) allow for clustering itself.

mod_jk or webapp on solaris with apache2

[David Bishop]

See subject :-)  This is actually a two-parter, though...

1)  Which should I use?  We are running apache2 and tomcat on solaris, on the 
same machine.  The tomcat usage is fairly light (a small percentage of the 
total usage of the server).  We've been running using apache1 and webapp for 
over a year now, and have been fairly happy with it.  The only reason that we 
are moving up to apache2 is because we want to do all of our ldap 
authentication within apache, and pass the info along to tomcat.  According 
to some archived postings to this list, that can only be accomplished using 
apache2.  While we're moving however, I'm reconsidering using mod_jk2.  Any 
thoughts?

2)  Whichever one we go with, I'll probably need some kind soul to help us out 
with getting working binaries.  I've used and admin'ed Apache+Tomcat for 
going on two years now, and I have *never* successfully compiled and used the 
apache connector module.  Basically, even when I manage to get it compiled (a 
very tricky business) it ends up complaining about missing symbols, or just 
segfaulting, or   Thus, everytime I've had to rely upon the kindsess of 
strangers to send me their working modules, and I use those.  In this case, 
I'm using apache 2.0.47 and Tomcat 4.1.27.  Apache was compiled with gcc 
3.3.1, and I'm on Solaris 8/Sparc.  If someone has a system vaguely 
resembling that setup, and wants to send me their copy of mod_webapp.so or 
mod_jk2.so, that would be simply wonderful.  And no, the binary connector 
modules available from the website don't work.  They don't appear to have 
been updated for several releases of apache, and who knows what they were 
compiled with...

Many thanks for the great programs, and any advice/tips/pointers that you 
offer!

It's a problem with Windows and has nothing to do with Tomcat. More

it doesn't happen on linux is because linux has better terminal

Gerald,

i got the following error message:
[snip]

Exception compiling Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK
JAVA_HOME points to the correct JDK.
Are you sure it points to a JDK and not a JRE? Often, people install the 
JDK which comes with a JRE and then point JAVA_HOME to the wrong one. If 
there's no $JAVA_HOME/lib/tools.jar, then your install is either 
incorrect (JRE instead of JDK) or broken.

Re: Session vs. Application Replication

[Filip Hanik]

just different ways of looking at it.
if you are saying that "application" replication is to replicate the data in
the application context, then no, it doesn't do that,

Pardon my Ignorance, but, how is session scope the same as application

Howdy,
Since HTTP is stateless, session replication is enough for servlet
webapps to achieve clustering.  That is, session replication =
application replication.  If you're using more J2EE than servlets, e.g.
EJBs, your app server will (hopefully) allow for clustering itself.

Re: Windows freeze...

[Leo Larraquy]

Could you recomend me any Windows version to avoid this?
Is there some way to send the output of the console to a file?? if not, is
it possible to always click  in that console so as to left the
selection-mode "unselected"??
I`m asking you this because I`ve got no problem on doing this in my
company/work place.
But I`m thinking about this situation, that is likely posible, server is
restarted, the user clicks to start Tomcat , how can I advise him not to
click that window???
Excuse me about not beeing happy with your response, I understand that your
not the person who made Tomcat, but I really can`t understand why Linux
doesn`t have these problem and Windows does.

Thanks.

I've had this "problem" before. It turns out that in some DOS windows,
when you click on them, they suspend the console output because the
mouse is in "selection" mode.
Pressing  gives you miles of queued-up output. It's like turning 
on scroll lock on a real console.

Just try not to click *inside* the DOS box when you switch to it. 
Instead, head for the title bar, of better yet, ignore your mouse and 
use ALT-TAB :)
You can also turn off the "click inside dos-box freezes output" feature 
by turning *off* "QuickEdit Mode" in your dos-box properties 
settings.  Before I figured this out, I spun many cycles running back and 
forth between servers to investigate these hanging complaints.

Can we, using tomcat's clustering, somehow replicate not only session
information for a given user (which would allow that user to transition
amongst the servers as traffic increases) but also maybe the application ??

Alexander,

Next time, please post this to a Java or JDBC or Oracle mailing list. 
This is unrelated to Tomcat.

I have a servlet that getting post request from form with 
enctype="multipart/form-data" as part of the form is file
upload. On the first run it works OK, on the second i am
getting:

java.lang.NullPointerException
What is the value of the string that you are passing to setString? Is it 
null? If it is, then I'd call this expected behavior.

If you want to set the value of a column to NULL then you must use 
PreparedStatement.setNull().

Sheesh, at a 615 level course you should be checking for nulls.

Re: Tomcat 5 to start automatically on linux at bootup

[Oscar Carrillo]

Also my page:

http://daydream.stanford.edu/tomcat/install_web_services.html

You can download one for apache, tomcat, and postgresql. It will probably 
be the same as the one Tim noted, except mine has a status command for 
tomcat that tells you how many threads/processes are running for tomcat.

I also have the LD_KERNE_ASSUME=2.2.5 set so that tomcat doesn't
occasionally crash due to the threading issues with RedHat.

I would look at your form, line 34, and maybe not call setString on the
PreparedStatement object if the form input is null.  Or maybe call
setString with "".  Or maybe add other input validation before/after the
form is submitted.

Re: Tomcat 5 Problem with finding servlet class

You should probably be keeping all your JARs in your web app, or in a

Re: Windows freeze...

[Christopher Schultz]

Leo,

On Windows, when an applicacion throws an Exception, for the first
time, Tomcat freezes, until I hit the keyboard or I do something on
the DOS console that appears when Tomcat starts up.
I've had this "problem" before. It turns out that in some DOS windows,
when you click on them, they suspend the console output because the
mouse is in "selection" mode.
Pressing  gives you miles of queued-up output. It's like turning 
on scroll lock on a real console.

Just try not to click *inside* the DOS box when you switch to it. 
Instead, head for the title bar, of better yet, ignore your mouse and 
use ALT-TAB :)

Re: ServletContextListener vs. InitServlet (was "modifying shutdown behaviour?")

[Christopher Schultz]

Yoav,

- ServletContextListener cannot flag that an error has occurred (other
than some type of logging)
You could throw a runtime exception, making the context unavailable in
tomcat.
Sure, but that's not very clean: the context startup just bombs. At 
least you get a "servlet unavailable" if you servlet doesn't startup 
properly.

True, but it's memory footprint isn't that big of a deal.
Could be a huge deal, depending on the servlet instance variables.  The
same is true for a listener.
So there's no difference in footprint, then :)

For some containers, it doesn't matter whether the servlet is mapped or
not, or servlets are mapped automatically.  Even if the performance hit
is tiny, it's still there, and there for every request.  At many
concurrent requests, it could become an issue.
Fair enough.

True.  Whether one considers that a drawback is a personal
consideration, along the lines of those poor souls who still have to run
JDK 1.1 ;)
Ugh. Or non-Swing GUIs. 

I've only seen one brain-dead servlet container ever create more than
one instance of a servlet: that was JRun 2.x.something. That wasn't
it's worst problem :)
Why would it be brain-dead to create more than one instance of a
servlet?
I can't think of a single reason to instantiate more than one instance 
of a servlet. (Unless you're using the SingleThreadModel thing; it seems 
like that marker interface exists only to allow newbie programmers to 
avoid understanding threading and local variables).

Oh, I just meant more heterogeneity.
Hmm... I guess that depends on the project, the people, other variables.
Of course. However, we did get the question "How do I cleanup after 
shutdown?". The servlet API only takes about 15 minutes to browse 
completely...

At 09:46 AM 10/28/2003, you wrote:
As far as I can remember there have been posts in this

this is not my experience, it's just something I've read)
My be it's time for a developer to shed some light on this.
The point is not really whether Tomcat does or doesn't give you the same 
HttpSession facade every time.  The point is that this is an *internal* 
implementation decision that can change at any time.  And even if it's 
never changed for Tomcat, you can't rely on it for other servlet 
containers.

My personal preference (and I've seen the benefits in multiple projects 
I've worked on), is to *not* rely on objects out of my control for 
functionality such as this.  What happens when you need to put an 
additional front end on your code to support WebServices, for example -- 
you still want to rely on any object in the javax.servlet package?  Don't 
think so.

If your project is limited in nature, then assume Tomcat and use an 
object in the session.  If you're building a complex, wide application, 
create your own synchronization framework (or use something pre-built but 
unrelated to J2EE).  It'll give you maximum flexibility when you start to 
support other appservers, clustering, client types, etc.

Tomcat 5 Problem with finding servlet class

[Paresh Varatkar]

Hi Guys,
I am deploying application in tomcat in different way.
As the application already have hard coded path references which are too tedious to 
remove,
I am using specific directories to deploy my jars.
I am setting classpath manually.
This all works excellent with Tomcat 3.2.4
With Tomcat 5, In catalina.bat file I am changing classpath in same way.
At the end it shows correct classpath set as follows

Windows freeze...

[Leo Larraquy]

Hi people, I`ve got a really simple question but a can`t solve on my own.
On Windows, when an applicacion throws an Exception, for the first time, Tomcat 
freezes, until I hit the keyboard or I do something on the DOS console that appears 
when Tomcat starts up.
But it doesn`t happen on Linux! I`ve been told that Windows losses control on that new 
window, and it can`t print the stackTrace, or even a "System.out", until you do 
something to activate that window again. 
Is there some way to solve this?? 
Thanks in advance. 
Leonardo Lopez.

character sets showing as ?

[chad kellerman]

Hey guys, 
   I moved a few tomcat Apps from a 6.2 server to a 7.3 server.  Running
the same version of Tomcat.  But now the character sets that are
displayed are coming out as ? ..  They are all spanish character sets. 
I tried changing to the character set to utf-8 from iso-8859-1 but still
it comes up.

  Anyone ever seen this before?  Maybe point me in the right direction.



Thanks,
Chad

tomcat.

Filters have their own parameters, like servlets.  But if you mean that
you could have context parameters with the same names but different
value: yeah, you could, and that'd be confusing at best.

Could be a huge deal, depending on the servlet instance variables.  The
same is true for a listener.

For some containers, it doesn't matter whether the servlet is mapped or
not, or servlets are mapped automatically.  Even if the performance hit

True.  Whether one considers that a drawback is a personal
consideration, along the lines of those poor souls who still have to run
JDK 1.1 ;)

Why would it be brain-dead to create more than one instance of a
servlet?

Hmm... I guess that depends on the project, the people, other variables.

Re: ServletContextListener vs. InitServlet (was "modifying shutdown behaviour?")

[Christopher Schultz]

Yoav,

If you have a servlet which initializes resource for your context (like
an InitServlet), you can simply implemnent the "destroy" method to
release your resources.
This may be easier than writing a ServletContextListener, and has fewer
moving parts.
I would strongly disagree ;)  The container is free to destroy and
reload any servlet, including load-on-startup servlets, at any time it
deems such action necessary.
If you need something done on shutdown or startup or both, it's much
cleaner to write a listener for that purpose than a servlet, for
multiple reasons.
There are also some reasons not to do this. Here's one.

- ServletContextListener cannot flag that an error has occurred (other 
than some type of logging)
- Servlets have their own init parameters specified in the web.xml file. 
If you use a listener, you have to share the global ones. If your filter 
and something else happen to have the same name for the configuration 
parameter, you have no resource but to modify the source. (The solution 
to this, of course, is to use names that are highly likely to be unique, 
like pre-pending your package name onto the parameter)

- The footprint of a servlet in memory is bigger
True, but it's memory footprint isn't that big of a deal.

- Another servlet adds to request mapping overhead, reducing performance
Most often, init servlets aren't mapped to anything, so there's no 
performance hit. The performance hit would be marginal anyhow, given the 
matching alrogithm. You'd incur maybe one String.equals comparison per 
request. Comparing strings that don't have the same length is pretty quick.

- Servlets are not supposed to be written only for init/destroy
functionality, ServletContextListeners are expressly designed for this
purpose
However, you must be running a servlet container which supports the 2.3 
API in order to use ServletContextListener (unless you implement 
something like it yourself for older containers).

- It's a lot easier to mess up thread-safety in a servlet (which of
course may have multiple instances in memory) than in a listener.
I've only seen one brain-dead servlet container ever create more than 
one instance of a servlet: that was JRun 2.x.something. That wasn't it's 
worst problem :)

Thread safety shouldn't be a problem if you're initializing things at 
startup. I'd say that if you're capable of screwing up a servlet, you're 
equally capable of screwing up a listener ;)

The moving parts claim you make -- I'm not sure I understand that.  Mind
elaborating? ;)
Oh, I just meant more heterogeneity. Most people have servlets. One more 
servlet isn't a big deal. Adding something completely different 
(although much more suited for the job) creates (a small amount of) 
confusion within the project.

4.1.27 Session problem on Solaris

[Jeff Tulley]

We are seeing an issue that has the same symptoms as if I were trying to
do load balancing but not getting sticky sessions -namely that our
application every once in a while starts thinking that the session is
not authenticated and prompts on every other request for a login.
The difference here is that we are only dealing with one tomcat
instance, so there is no load balancing in the picture.  (It is just
easier to describe this way since the symptoms are the same).

We have an L4 switch up front, and then requests go straight to
Tomcat's HTTP connectors.  This is Tomcat 4.1.27 on Solaris (9?)

If the browser where the problem is seen is closed down and the user
logs in again in a different browser, the application goes back to
behaving correctly.  So far we have only seen this over HTTPS, though we
are trying to duplicate the problem without the L4 switch and non HTTPS.
 This problem is also very intermittent.

Does anybody have any idea what could cause such a thing to happen?

RE: Session exclusivity (was Form Double Submit Detection)

[Ralph Einfeldt]

As far as I can remember there have been posts in this 
list, where people said that they have seen different 
session objects within the same session.

This was explained with the fact that there is a session 
facade which can change anytime. So the session should 
be a quite weak monitor to rely on. (But as I said,
this is not my experience, it's just something I've read)

My be it's time for a developer to shed some light on this.

Re: Session exclusivity (was Form Double Submit Detection)

[Christopher Schultz]

Ralph,
BTW: In my version of tomcat (4.0.3) jasper generates
code for the jsp's that synchronizes on the session 
to access session attributes. Is the current version 
doing the same ?
I'm using 4.1.27 and yes, is does synchronize on the session object that 
it gets (I'm only including the relevant parts):

javax.servlet.jsp.PageContext pageContext = null;
HttpSession session = null;
	.
	.
	.
  _jspxFactory = JspFactory.getDefaultFactory();
  pageContext = _jspxFactory.getPageContext(this, request, response,
null, true, 8192, true);
  session = pageContext.getSession();
	.
	.
	.
  synchronized (session) {
test = (Object) pageContext.getAttribute("test", 
PageContext.SESSION_SCOPE);
	.
	.
	.
	}

So, it looks like the Catalina folks feel like the session is okay to 
synchronize on, but I agree that one shouldn't bet the farm on a 
"session" being a good monitor.

I think it's not MSIE that is confused.

What you see are serverside exceptions.

I guess something in the generated java is 
confusing javac.

What kind of linefeeds do you use in the jsp?

For an existing file, getCanonicalPath() sometimes can produce
a pathname whose case doesn't match that of the existing file's pathname.
This doesn't matter in terms of being able to access the file, but it appears
that some applications, such as TomCat, depend on getting the correct case.

Hi,

I have accidentally discovered a way that Tomcat can serve 
the source code
of a JSP file. 

Running Tomcat 4.1.27 standalone, JDK 1.4.2,  Win XP Pro. 
and also Win 2K
Server

Mostly the default configuration, but using port 80 rather 
than 8080. 

pointing my browser to http://localhost/examples/jsp/num/numguess.jsp
returns the page as expected for the number guess example
but http://localhost/examples/jsp/num/numguess.JSP 
and other combinations such as
http://localhost/examples/jsp/num/numguess.JSp and
http://localhost/examples/jsp/num/numguess.Jsp

give a file download window for the source of numguess.jsp.

Is there a workaround for this?

Best Regards
Jon

You have to get the source, and build. There will be a TC 5 SAR in the 
output dir for the Tomcat module.

Using it is not straightforward, though:
- you have to replace the servlet & JSP API JARs in lib
- you should add commons-logging to your system classpath to avoid problems

Re: mod_jk2 binary for Apache 2.0.47/Win

[Florian Ebeling]

Jean-Max,

I was wrong assuming that one needs a mod_jk2 needs to bear the exactly 
same version number as the Apache2. I didn't even give it a try, because 
I read it at several places in the apache docs. I got mod_jk2 running 
now, with kind assistance of Asif Chowdhary, as you probably hab been 
able to read in the list.

I installed the mod_jk2-2.0.43.dll in apache/modules. Here is what I put 
into the diffrent config files:

httpd.conf: just one single row like this:
LoadModule jk2_module modules/mod_jk2-2.0.43.dll
Then I added a worker2.properties in Apache/conf/ like this:

[logger]
level=DEBUG
file=c:/programme/apache group/apache2/logs/jk2.log
[config]
file=c:/programme/apache group/apache2/conf/workers2.properties
debug=0
debugEnv=0
# Shared memory handling. Needs to be set.
[shm]
file=c:/programme/apache group/apache2/logs/shm.file
size=1048576
debug=0
#disabled=0
[channel.socket:localhost:8010]
port=8010
host=127.0.0.1
debug=0
# Example socket channel, explicitly set port and host.
# [channel.socket:localhost:8009]
# port=8009

# tomcatId=localhost:8009
# debug=0
# define the worker
[ajp13:localhost:8010]
#channel=channel.un:/usr/local/pds/tomcat/work/jk2.socket
# To use the TCP/IP socket instead, just comment out the above
# line, and uncomment the one below
channel=channel.socket:localhost:8010
# define the worker
# Announce a "status" worker

[uri:/jkstatus/*]
info=Display status information and checks the config file for changes.
worker=status:status

JSP generated HTML code squashed in one line

[Baer Peter Christoph Alexander]

Hi,

we have a problem here that looks pretty strange to us. We have extensively
searched the mail archive and we googled a lot, but found no suitable
information. Should we nevertheless ask something obvious, please forgive
us.

Here is the problem:
Tomcat 4.0.6 LE generates HTML pages with a lot of the code compressed into
a single line, when running on *some* machines under Windows XP. That is,
the first line of the generated HTML is very long. This appears to confuse
MSIE: We see lots of runtime exceptions regarding missing closing braces
("}").
On another machine, running Windows 2000, an apparently identical
installation works just fine. No such runtime errors.

We found another difference in the work directory tree. The filenames of the
servlets on the Win XP machines start with _0002 and contain this string a
number of times each. On the Win2k computer we have just jspname$jsp.java as
the name of the generated servlet.

We don't know, if the two phenomena are connected, and we are absolutely
clueless what the differences are caused by. 

If anyone of could give us a hint of how to make the Win XP installations
work as properly as the Win2k instance, your help will be greatly
appreciated!

Our environments are: Windows 2000 (works fine) and Windows XP (sucks),
J2SDK 1.4.2_01 from Sun and Tomcat 4.0.6 LE.

Many thanks in advance!

Regards

Peter Bär

RE: Session exclusivity (was Form Double Submit Detection)

To be honest, I'm not shure.

As I'm currently not really using tomcat (or another
servlet conainer that works with session facades) I 
have not thought or tried enough to be shure.

For those who want to be very shure, there is still 
the option to synchronize on something outside of 
the session.

BTW: In my version of tomcat (4.0.3) jasper generates

to access session attributes. Is the current version

(Just define a session bean in a jsp and have a look 
at the source in the work dir )

Howdy,
  I want to schedule a session clean up in a tomcat 5.1 clustered

My main concern is, will there be a conflict in the clean up as all the
nodes in the cluster could start doing the clean up.
Is there a concept of "primary" node in clustering from which we could
manage such admin tasks.

Re: Why not to create threads? (OT)

[Christopher Schultz]

Yoav,

The rest of the message aside, I had an only partially related question:

(and a poor one at that :)). But the fact that
many servlet-based applications end up going the way of the EJB, you
might want to play by their rules if you can.
Can you quote research that shows a large percentage of servlet-based
applications are eventually migrated to be EJB applications?
I only said "many", not a large percentage. I'm sure there's been more 
than one :)

Honestly, I'm not willing to conduct such a study and I was shooting my 
mouth off. Sometimes, servlet-based apps move to EJB containers. If 
that's your case, you might want to avoid creating your own threads.

To be safe no matter what, I avoid creating new ones at many (not all) 
costs. There's more than one way to do it (don't tell any of the Perl 
peeps out there that I'm stealing their line).

Re: Why not to create threads?

[Tim Funk]

You are allowed to create your own threads. But there are restrictions and 
limitations for user created threads such as ...
- They should not touch Request and Response objects
- The should be able to know when the servlet container stops if non-daemon 
so the jvm may gracefully terminate
- If daemon - have a quick shutdown(or appropriate) since the container may 
shutdown the moment all threads are done with their service() method (I 
probably got this wrong, but the spec describes this better)
- High perfomance containers are allowed to "restrict" thread creation
- All of the fun concurrency issues

Session exclusivity (was Form Double Submit Detection)

[Christopher Schultz]

Ralph,

Does that mean that you 
can never have exclusive access to your own session?

Yes you can, but the only safe way is to synchronize
on an object inside the session, not the session itself.
Well, not always. Because of threading and memory issues with the JVM, 
one thread might put something into the session, but another thread 
cannot see that new data, yet. On the other hand, one thread could be in 
the process of putting something in the session, and the second thread 
could think that it's a valid object, when it might not be.

(Stupid JVM relativity... :)

Does a synchronized block constitute a complete memory boundary? Must 
the thread sync everything with main memory? I thought it only had to 
synchronize the data associated with the monitor itself.

Re: Why not to create threads?

[Christopher Schultz]

Chris,

Why should I be avoiding creating my own threads in a web
application?  I have a couple of scheduled components, and I'm not
sure how else I would implement them.
I realize ther sometimes it's just necessary, so I'm not trying to tell
you that you're wrong for creating threads. That being said...
First, HTTP is a connectionless protocol. We've only invented the
concept of the "session" to get around this feature. All transactions
should take place within the request-response model. That doesn't work
for all web sites, so we use sessions. Fine.
Second, managing your own threads within a servlet-type of environment
is tough. You have to make sure that you don't create too many threads,
or that they don't take up too much processing time, that you don't lose
track of them, etc. You appear to have a very domesticated daemon thread
that's almost unrelated to responding to requests, no?
Third, the J2EE EJB specification for Enterprise JavaBeans specifically
forbids it. You aren't supposed to be creating your own threads because
you're not suppsosed to know where your code is running. Sure, on one
machine, it's running right there, in the same VM you thought it was
going to start in. However, in a clustered environment, your code may be
running on a completely different server.
There's actually a lot of fascism when it comes to the EJB spec. Among
other things, you're not supposed to do any of the following:
- Create your own threads
- Instantiate any of the classes in the java.io package directly
Now, I know that not everyone is running an EJB container, and that J2EE
is a ton of specifications and services, of which EJB is only one
(and a poor one at that :)). But the fact that
many servlet-based applications end up going the way of the EJB, you
might want to play by their rules if you can.
Note also that if you have a Servlet container that merely connects to
an EJB container then you are not bound to these restrictions. However,
many EJB containers also act as servlet containers, and they may impose
these restrictions across the board.

The advantages or disadvantages of breaking a large webapp into multiple
smaller one depend on the webapp itself.  If the subsystems you describe
can operate fairly independently of each other, they can be broken apart
for additional scalability and availability: it's easier to scale a
small application.  If, however, the multiple subsystem are really just
tightly integrated classes, you're probably better off leaving them
together.

It's OK to create and use threads as long as you're careful for
synchronization issues.  Threads are a powerful construct when used by
able developers but can cause very difficult problems to diagnose/debug
if not used carefully.

You should probably not write threading utilities from scratch.
Instead, use something like Doug Lea's concurrent library,
http://gee.cs.oswego.edu/dl/classes/EDU/oswego/cs/dl/util/concurrent/int
ro.html, which will be part of the JDK 1.5 release.

Sorry for my ignorance, but this is a DataSource *and* a JDBC driver all

What does your DataSource config look like -- you're creating it using

Re: Configuring tomcat to serve request from specific IP addresses

[Christopher Schultz]

Is there any way to configure tomcat to enable its services (HTTP
request/responses ) to specific IP address(s) only?
I'm sure you can do something like Apache's:

Deny From All
Allow From 
... but that would require a restart.

Programmatically, you can do this by poking the "allowed" ip address 
into the application scope and then checking the ip address of each 
request against that address; reject those that don't match. (Please see 
the past 24 hours of discussions about IP blocking, AOL/corporate users, 
etc.).

Just remember that you might want to have the "ip changer" servlet be 
unprotected, or your could lock yourself out very easily :)

Re: Number of processes and relationship to mod_jk, Apache, tomcat

[Christopher Schultz]

Andrew,
I am trying to understand the relationship between applications in Tomcat,
the number of Tomcat processes, Apache mod_jk and the number of threads.

Apache: lsof -i tcp:80 | wc -l
This gives me 12 processes listening to port 80 (I checked these are related
to the number of Apache instances)
You should be able to predict this from the httpd.conf file. Do the 
numbers add up for Apache?

Tomcat direct port: lsof -i tcp:8080 | wc -l
This gives me 50 process that also correspond to the number of tomcat
instances running(i.e. the number of java instances I see in ps )
What UNIX flavor are you running? I know that in old versions of Linux, 
each pthread was shown as a separate process. Thus, it looked like many 
processes (really threads) all held the same resource. For example, they 
all had the same resident memory footprint (because the memory is 
shared) and they all were bound to the same ports.

In the later versions (mine being one of them, I've got kernel 2.4.20), 
they only show up as one process. Thus, I get this output:

[EMAIL PROTECTED] ]# /usr/sbin/lsof -i tcp:8009
COMMAND  PID   USER   FD   TYPE DEVICE SIZE NODE NAME
java9313 tomcat   15u  IPv4  69785   TCP *:8009 (LISTEN)
[EMAIL PROTECTED] ]#
I'm guessing that you're getting multiple lines that all look like this. 
Is this accurate? Only one process can bind to a port at any given time, 
so multiple processes (even with separate pids) might appear to be bound 
to that port.

Tomcat mod_jk port:
lsof -i tcp:8009 | wc -l
gives me 550
Again, see the discussion of the threads/processes above.

Also note that you may have many more threads that you thought you 
would. I recall that each (non-"nio") stream in Java requires a separate 
thread, so System.in, System.out, and System.err already give you three 
threads. Then, you've got the main thread, plus the thread pool to serve 
requests from remote clients. That may be large, although having that 
number higher than your Apache request processor limit is probably a waste.

Now I know that these numbers will change depending on load but I am trying
to understand the relationship.
Well, some numbers should not change. For example, there should be a 
hard limit on the number of Apache threads/processes running. You can 
tune that in httpd.conf.

For the Java process, it's harder to predict because of the way the VM 
retires threads and when your server is creating them. Ideally, new 
threads wouldn't be created at all because there would be a closed 
thread pool (unless you have a min and max thread pool size and the 
number of threads depends on load).

So my questions is how do the numbers relate to each other?
The number of Apache processes is usually completely unrelated to the 
java process counts (except that there will be more java threads than 
Apache processes :).

How does this effect performance?
Most of the "processes" are very lightweight. Apache is a lean, mean, 
web-serving machine so don't worry about that. What you should worry 
about is if your thread count continually goes up and never comes back 
down. You'd have a nasty resource leak, then. If you avoid creating your 
own threads in your web application (which you should be avoiding 
anyway), you're generally okay.

Re: mod_jk2 binary for Apache 2.0.47/Win

[Florian Ebeling]

Hi Jean-Max,

this won't work, Apache accepts only modules with exactly matching 
version numbers.

I tried the mod_jk module, because this one is in sync with the Apache2 
release. You can get it here: 
http://www.apache.de/dist/jakarta/tomcat-connectors/jk/binaries/win32/

mod_jk is deprecated, I know. But it has been in production for a faily 
long time, so it shouldn't be too daring to use this.

To get it running, one has to do configuration in several places:

First, I created a file "workers.peroperties" in $TOMCAT_HOME/conf like 
this:

---
worker.list=worker1
worker.worker1.host=127.0.0.1
worker.worker1.port=8009
worker.worker1.type=ajp13
---
Then I added this to $APACHE_HOME/conf/httpd.conf, behind the section 
where all the othher "LoadModule ..." directives get listed.
---
LoadModule jk_module modules/mod_jk_1.2.5_2.0.47.dll
#AddModule  mod_jk_1.2.5_2.0.47.c
#AddModule  jk_module.c
#AddModule mod_jk.c
JkWorkersFile "c:/jakarta-tomcat-4.1.24/conf/workers.properties"
JkLogFile "C:/Programme/Apache Group/Apache2/logs/mod_jk.log"
JkLogLevel debug
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
---

- adjust path to your workers.properties here
- add path for a log file for the module here (eg. mod_jk.log)
Then, add this snippet to httpd.conf


ServerAdmin [EMAIL PROTECTED]
DocumentRoot "C:/Programme/Apache Group/Apache2/htdocs_javaroom"
ServerName javaroom
ErrorLog logs/javaroom-error.log
CustomLog logs/javaroom-access.log common
JkMount /*.jsp worker1
JkMount /javaroom/* worker1

- replace the virtual host server name with your server name
- replace "JkMount /javaroom/*" so that it specifies some webapp context 
of yours

And, finally, add the neccessary Tomcat Connector to your server.xml:


- I put it just behind 

Then restart Tomcat and Apache2 and ping your app.

One question remains: All the documentation, I consulted said one has to 
use a "AddModule ..." directive in the httpd.conf. But all the commented 
variants above prevent the apache from starting up at all. Do you have 
any idea what this might happen to mean?

Replicating Application variables

[Karthik Duddala]

We have a web application with multiple sub-systems . viz. , Order
Processing, Inventory Management etc., I need a way to isolate each of
these sub-systems.
One approach I have thought of is setting an Application variables which
then will be picked up the system and deny access to that particular
sub-system.

My question is : Can we replicate application variables like sessions? If
so, how can it be done?
Also, for clustering is there a master node or a controlling node ? The
reason i ask this question is, I need to know how to take care of session
clean ups. If I schedule session cleanups based on the session time stamp,
which node do i run it on? I cannot run it on every node as it will start
to run at the scheduled time on all nodes and create conflicts. Also, this
will help me decide my build strategy.

Subject: mod_jk2 binary for Apache 2.0.47/Win


Hi,

I am trying to integrate Tomcat with Apache2 via the mod_jk2 module and 
CoyoteConnector on the Java side. Nothing experimental here, so far.

Problem is
1) the module needs to be compiled against exactly the same Apache 
version into which it is to be deployed later
2) the only binary Apache2 is 2.0.47
3) the only binary mod_jk2 is against 2.0.43
4) I don't have a MSVC compiler suite
5) The jakarta-connector documents say that only MSVC is possible, so I 
conclude MinGW or Cygwin won't be helpful here

If anybody could point me to a solution to this it would be very helpful.

Thanks and regards,
-Florian

Number of processes and relationship to mod_jk, Apache, tomcat

[Andrew Panagos]

I am trying to understand the relationship between applications in Tomcat,
the number of Tomcat processes, Apache mod_jk and the number of threads.

For instance on a system I have the following
Apache 1.3.28, Tomcat 4.1.27, Java 1.4.2_02
I use the follow commands to see what is listening to different ports to get
an idea of what process or threads are running.
Apache: lsof -i tcp:80 | wc -l
This gives me 12 processes listening to port 80 (I checked these are related
to the number of Apache instances)

Tomcat direct port: lsof -i tcp:8080 | wc -l
This gives me 50 process that also correspond to the number of tomcat
instances running(i.e. the number of java instances I see in ps )

Tomcat mod_jk port:
lsof -i tcp:8009 | wc -l
gives me 550

I have included my condensed jk.properties and workers.properties files at
the end if that may help.
Now I now that these numbers will change depending on load but I am trying
to understand the relationship.

So my questions is how do the numbers relate to each other?
How does this effect performance?
How could I tune these numbers?

Now I have a vague understanding of how these relate but the numbers don't
add up for me. I have read the docs and searched for quite a while for a
better description.

Thanks
