[JBoss-user] How to configure JBoss-Jetty to serve static content?

[Herve Tchepannou]

Im running JBoss-Jetty-3.0.4.
My application allow to upload images that are stored in a directory
/home/app/resources/
I'd like Jetty to allow my users to access those images.
For example, http://mydomain.com/resources/a.gif will map to
/home/app/resources/a.gif.

How do I configure Jetty for that
thanx

[JBoss-user] getClass().getClassLoader().getResourceAsStream() not working inweb-app

[Herve Tchepannou]

I create rss.jar with a this structure:
  RSSPortlet.class
  rss2html.xsl

in RSSPortlet, I need to access the xsl file, so Im doing:
void foo()
{
   InputStream in = this.getClass.getClassLoader().getResourceAsStream(
"rss2html.xsl" )
   ...
}

I put rss.jar in WEB-INF/lib a rss.war.
When the RSSServlet try to call the function foo(), the rss2html.xsl is
not found ( the inputstream is null ).
Is this normal???

I'm using JBoss-3.0.4

XDoclet goes a long way and I also highly recommend that you purchase a
JBoss service contract - advice from a happy camper. They will help you get

JBoss doesn't do servlets.  JBoss itself, from my experience is the fastest 
server of its kind on the market.  Servlet engines on the other hand are 
slower than hell, because of the constant compile cycle when you introduce a 
newly timestamped jsp file.


You're probably better off asking speed-related questions for the servlet 
engine either to the jetty mailing list, or the tomcat mailing list, 
depending on which servlet engine you're using.


Without knowing which servlet engine you're using, it's impossible to tell you 
any specifics on speeding your jsp pages up.


However, one method you can use that is generalized for speeding up a 
JSP/servlet container, w.r.t. jsp pages, is to precompile all jsp pages 
before deploying.


This can be achieved using jspc for both Tomcat and jetty.  Jetty uses 
Tomcat's jspc.

My advice will be to expose the remote interface of the component, so that
you can test is with standard JUnit test cases.
Its easy and you test framework is simple.
But, you have to deploy your component to JBoss

What's the current best practice for unit testing EJB's, (both Entity 
and Session)?


I'm trying to avoid having to deploy them to a separate JBoss instance 
to test them.  More precisely, I want to be able to deploy them to an 
in-memory container, if possible, similar to Hypersonic's in-memory 
database.  Ideally, the EJB container would be running within the JVM of 
the JUnit test runner, persisting my CMP beans to the memory-resident 
Hypersonic db.


Possible or stupid?

Shouldn't this work like the following SQL query:

If you have any prob compiling the app on Windows because the command line is too long, remove unecessery jar files from

XPETSTORE_HOME/src/petstore/lib/main/xdoclet-1.2b1
and keep the following files:
xdoclet.jar
xdoclet-ejb-module.jar
xdoclet-jboss-module.jar

For the moment, xPetStore works very well with JBoss.
Im working hard to port it to JRun, but I'm having hard time to do it
because JRun template files are out to date and I'm not a JRun guru. Any
JRun guru here? your help is more than welcome.
For other app server (websphere,weblogic,iplanet,pramati etc.), help

RE: [JBoss-user] CMRs are Slow (was: Entity Bean Performance Tuning Help)

[Herve Tchepannou]

1. 
What's the read-ahead/strategy of findAll() ? Since you want 
to get all the beans value object, it should be set to on-find, 
otherwhise, you are going to have the N+1 finder 
problem
2. 
Since you're populating the ValueObject with the content of your CMR fields, 
because each access to the CMR fields will call their findByPrimaryKey() 
to load them. Me, I always load CMR when needed. If they are always needed, 
then I use de Dependant  Value Class
3. Internal/External ValueObject creation. This 
make sense because in the external, each call of a getter from the ValueObject 
passes via the beanProxy (+ interceptors), where in the internal case you 
are already in the bean, then no overhead of the beanProxy
4. It 
may be interesting to see the result if you load all the 1000 beans, but 
return just a page of 25 ValueObjects, which is how most web-pages works to 
avoid those performance problems - then, make sure that the read-ahead strategy 
of the findAll() is set to on-load

[JBoss-user] CMRs are Slow (was: Entity Bean Performance Tuning 
Help)

  The "Entity Bean 
  Performance Tuning Help" thread went off in various different directions. The 
  thread begged a sample and a little more detail as to what was slow. I've 
  identified the problem to be (CMRs) and provided a full sample 
  (attached).
   
  Lets rehash what 
  i'm testing:
   
      The code runs inside of a SSB with 
  a transaction on each method vs servlet (struts action) + manual transaction 
  as in the real app. I use hypersonic vs oracle in my real 
  app.
      
      calls 
findAll()
      dumps out 
  the time
   
      iterates through each calling all 
  methods and building a valueobject.
      this 
  should cache all results (checkout my jboss.xml)
   
      iterates through each calling all 
  methods and building a valueobject (a 2nd time)
      dumps out 
  the time
      
      iterates through each and calling 
  1 method on ejb, which builds the valueobject internally
      dumps out 
  the time
   
  I'm mostly 
  concerned with the last time, as it's what i do in my real case...because it's 
  the fastest. 
   
  The entitybean 
  has 2 CMRs. The read-all+fields time for 1000 cached beans using internal 
  valueobject generation takes about 670ms. But with 1 cmr it only takes 350ms. 
  And with No cmrs it only takes 150ms. [if you want slightly modified code, let 
  me know]. 
   
  Now 150ms is 
  great! But 350 isn't. It's more then double. Is this acceptable? Add a few 
  more and it's unusable for a lot of applications.
   
  Arguably cmp 
  EntityBeans were worthless till ejb2.0 and CMRs came along. But to actually 
  use them in JBoss is suicide for performance.
   
   
   
  The attached sample has a test class called "Test", 
  which can be run with -c to generate 1000 test rows. Also included is an ant 
  script which builds the test beans and deploys them to jboss, if you set your 
  jboss.install path in build.properties.
   
  Here the actual 
  output from my last test run:
   
  14:31:36,312 
  INFO  [STDOUT] creating 1000 Blobs...14:31:43,968 INFO  [STDOUT] 
  Creation complete, took 7656ms.14:31:46,328 INFO  [STDOUT] testing

  2640ms for 1000 objects.14:31:53,437 INFO  
  [STDOUT] Internal ValueObject creation took 672ms for 
  1000 objects.
  These results 
  also beg the question of why the interceptor stack takes so long to 
  transversion, hense the extra 2000ms for 1000s ejbs, but lets leave that for a 
  seperate thread.

Subject: [JBoss-user] JBossMQ messages being lost after restart Solution



Hello,


I solved the JBossMQ message being lost after restart.  I was using '/' 
characters in my queue name, and also using file persistence. 
Apparently the two don't match.  JBoss almost gets it to work, for it 
escapes out the '/' characters for the directory for storing messages. 
I believe somewhere in the code it is not escaping the queue names.


So, bottom line:


If using JBossMQ and file persistence, DO NOT put '/' characters in your 
queue name.


Thanks,
Seth

RE: [JBoss-user] How to use application specific properties - an example

[Herve Tchepannou]

Title: RE: [JBoss-user] How to use application specific properties - an example





1. I attached all the classes for my MBean:
    - TeamSpaceConfigMBean.java:    This is the MBean interface
    - TeamSpaceConfig.java:     This is the MBean implementation
    - TeamSpaceConfigProxy.java:    This is a Proxy class to access the MBean. This class hide all the ugly JMX method/attribute calls. This is the class that is actually used in the EJB


2. In jboss.jcml, I add the following block to load my MBean at boot time:

    name="DefaultDomain:service=TeamSpaceConfig">
    
  
    



3. In any EJB, I do this to call my MBean:
TeamSpaceConfigMBean conf = new TeamSpaceConfigProxy();
_filesDir = conf.XXX()


thats it :-)

In my application, I also have some application properties store in a property file.
I prefer creating a MBean that loads all thoses properties when JBoss boot,
an in my EJB, I can nicely access those properties.
The other advantage of MBean is that you can connect at http://localhost:8082 and change

And also, JMX is more and more a standard in J2ee world

We have a local property file containg such things like name of
machines, files, ip-addresses and such for legacy interfaces.  I found
out (the hard way) that I could place this file in the
${JBOSS_HOME}/bin directory, presumably because it is from there we
run the server.  It shouldn't stay there of course, and further we
need it within the client too.


I know we could use some property mechanism within ejb-jar.xml, but I
cannot figure out how to get this with XDoclet and I am not sure I
like this because different machines/servers need different
properties.


Is there a Right (tm) way to do this?

Re: [JBoss-user] EJB/MBean communication

[Herve Tchepannou]

This is the method that I used...
but I find the JMX call very ugly, then I tryed to use DynamicProxy to 
wrap all my MBeans,
but I had all kind of problems with ClassLoader...
anyway, now I create a Proxy class for each MBean, then all the EJB 
calls are more 'natural'.
So far so good.
JMX is very powerful feature.. its really amazing !

JBoss rocks!

see, then if call the handle() method with an array containing a NameCallback

[Herve Tchepannou]

Title: JBoss-JAAS problem: My custom LoginModule not initialized with my custom CallbackHandler, but with  javax.security.auth.login.LoginContext$SecureCallbackHandler





Im trying to use JAAS to authenticate users of my application, but for some reason, JBoss doen't pass my CallbackHandler to my LoginModule initialize() function. The custom handler that I receive is of type javax.security.auth.login.LoginContext$SecureCallbackHandler

I added in $JBOSS_HOME/conf/catalina/auth.conf the following lines:


tspace {
    tspace.jaas.TeamSpaceLoginModule required
    debug=true
    domain=sympatico.ca
    ;
};


In my LoginAction (struts-action), I did the following:


public ActionForward doExecute( ActionMapping mapping, 
    ActionForm form,
    HttpServletRequest request,
    HttpServletResponse response )
    throws  Exception
{
  LoginForm    login   = ( LoginForm )form;
  LoginContext lc = new LoginContext( "tspace", 
    new TeamSpaceCallbackHandler( login.getLogin(), login.getPassword() ) );
  lc.login ();
  Subject  subject = lc.getSubject ();
  ...
}


From want I understood, the initialize function should receive a CallbackHandler of type
TeamSpaceCallbackHandler, not javax.security.auth.login.LoginContext$SecureCallbackHandler.


Anyone know what's my problem?
thanx in advance

Make sure that you ALWAS close your connection in the 'finally' clause!!!


Ex:

Hi;


I have a DB2 pool defined in my jboss.jcml file. Every time I use the pool
from my ejbs jboss opens a new connection and don´t reuse the actual
connections. When jboss reachs the max size of the pool it hangs.


Any ideas?


I append the pool definition at the end of this mail.


Thanks in advance.

Title: FW: [JBoss-user] interesting article comparing JBoss and JOnAS






Its true that having Tomcat-JBoss embeded improve the performance, but all clients
are not necessarely web-clients. Im develloping an app now where some clients will
use Swing, which mean that I'll access my session bean from my swing form


It think it would be interesting for JBoss to have a realistic app like JOnAs for
benchmarking the product, it may be very interesting for marketing the product...
I mean, Jonas is opensource like JBoss, and it looks like they are used by Kovair
in production environnement!

I just read this article, with particular interest since I switched from
Jonas to JBoss about 4 months ago. I switched because in my home-brew tests
Jboss seemed to handle more traffic better than Jonas. Which brings me to my
question. The main benefit of Jboss that attracted me was that I could run
Jboss and Tomcat in the same VM, thus getting rid of all those servlet to
EJB calls over the wire. I am running servlets with BMP session
beans--configuration 1 from the rice tests.
 
The rice tests, unless I misread them, had tomcat always running in its own
VM. And in those tests, Jonas seemed like the better server, although only
marginally for servlets with BMP session beans. Has anyone else had similar
experince? Would you say that the rice tests don't really show a
"real-world" comparison of the two application servers because they didn't
take advantage of embedded tomcat for JBoss?

The configuration/deployment stuff is unfortunately still changing enough

It's not a question of $$...
If a book is published on JBoss, I'll buy it right away. There are a lot of book published
on the net that are sold on bookstore too
It just doesn't make sense to buy doc of an opensource product for testing the alpha release.  I'll just wait for the final release of JBoss3.0.

By the way, they may be a lot of people not in north america who doesn't have access to credit card

Subject: [JBoss-user] Stopping JBoss



OK, this one _must_ be more trivial than it seems to me. I am starting
JBoss (under Linux) by calling 'run.sh &' in the bin/ directory of
JBoss. After that, I have about 50 threads that seem to be doing the
same thing: run org.jboss.Main.
Everything works quite fine. The only problem is: I don't know how to
shut the server down. Right now, I just do a 'killall java'. This only
works because JBoss is the only piece of Java based software on my
machine. 
But there has to be a more elegant way to stop JBoss. Could anybody
please help me to figure out how to do it the right way?


Thanks in advance,

Do you use the run_with_tomcat.sh script? The Java compiler is missing

RE: [JBoss-user] JBoss/Linux and threading - Command Pattern

[Herve Tchepannou]

Title: RE: [JBoss-user] JBoss/Linux and threading - Command Pattern





- One good advantages of the Command pattern is that you can test most of your application logic out of the EJB container, if the business objects are implemented as standard Java classes instead of entity beans. (BO, DAO, Command and CommandServer all implemented as standard java classes)

When you want to move the commands to a EJB environement, implement the CommandServer as SLSB

Subject: Re: [JBoss-user] JBoss/Linux and threading



Command pattern is a control abstraction intended to decouple business
and presentation logic. To oversimplify, it replaces a method doIt()
with a class DoIt. Like most patterns, it has many variants and can be
both productively and dangerously creative. It can be used to implement
EJB or replace EJB (cf.
http://www.theserverside.com/patterns/thread.jsp?thread_id=654). It is
orthogonal to whether EJB is used, but does offer flexibility in the
decision.


Like other patterns, it is also handy for lulling gullible managers into
approving extra work without their knowledge. If one claims "Technology
X is too slow/dumb/etc." and the manager asks "What's the alternative?",
"Simplify the code with Pattern Y" sounds a whole let better than "Write
it ourselves".


The case in question is EJB vs. roll-your-own, an important build/buy
trade-off. btw, it's good to see real numbers posted. It'd be great to
get a head-to-head comparison with code and other metrics, esp. access
time. Most of us have committed to one solution, for better or worse,
and can't afford to run dual implementation trials.

[JBoss-user] JBoss/Linux and threading

[Herve Tchepannou]

1) I've started an application with JBoss on a PII 300, Linux RH6.0
My application had:
   - 5 business object as CMP Entity beans
   - 4 Stateless Session beans
   - 4 MDB
   - 100+ test cases
After running the test cases, I was monitoring the number of thread
spawned by jboss::
   1srt time: 150 threads
   2nd time: ~350 threads
   3rd time: ~500 threads
very quickly, my system was running out of threads :-(


2) I redesign the application using the command pattern:
Ma application has
- 5 business objects as standard java classes
- 5 DAO classes for managing the persistent with straight JDBC calls
- 30 commands for executing all system actions, build as standard
java classes
- 1 command executor as Stateless JavaBean
- 100+ test cases
After running the test cases, I obtained the following results:
1st time: 3 threads
2nd time: 2 threads
3rd time: 2 threads
etc

3) I add into my application 4 MDB for async processing (deleting files,
sending mails etc) and
a rerun my test cases, here are the results that I obtains:
1st time: 79 threads
2ns time: 79 threads
3rd time: 70 threads


CONCLUSION:
Think twice before using all EJB features!

As I mention on the website (news blurb to appear tomorrow) JBoss' number

Keep it coming, 3.0/RH is just going to clean this industry.  It is too

RE: [JBoss-user] cmp primary key

[Herve Tchepannou]

Title: RE: [JBoss-user] cmp primary key





In CMP, in the ejbCreate(), you must generate the key and assign it to the primary key field of your bean.
The strategy of generating the PK depends on your context.


1. If the PK is a string
You can use a UUID generator to generate a key of 32 character. That key will be unique within the application server network. (This is portable to all app server and database).

I have an implementation of it that Im using for my app, If u need it, jut contact me


2. If the PK is int or long
- If your database supports sequences, you create 1 sequence per entity bean in the database. in ejbCreate(), request the next value of the sequence via a JDBC call. (This is not portable to all db. PostgreSQL, Orable supports sequences)

- Use a SessionBean for generating the unique key.

I'm a newbie for sure, but I've been surfing around for
a solution to assigning unique primary key values with
CMPs. I have seen lots of vague descriptions of how
to do it and some specific ones that are all followed by
other comments from people why that solution doesn't
work.


Does anyone have a specific solution and the complete
code to do this they can share? This seems like it must
be a very common problem that ought to have a standard

RE: [JBoss-user] Custom finders in Jaws

[Herve Tchepannou]

Title: RE: [JBoss-user] Custom finders in Jaws





You cant do that with finders.
You can't use a finder to return only one field. A finder returns you either 1 entity bean or a collection of entity beans.

If u want to extract the last names, call findAll() and then traverse the returned collection and collect all the first-names.

For ur case, you may want to consider using JDDC

Howdy, How can I declare a findByLName() in jaws, I tried this.Like the docs
chpt 6

 ClassBean
 ... 

 findByLName
 LNAME!=null 
//What I want is for the collection to contain all lastNames from all
records(I guess I need a wildcard here so It will return all)
//Similar to a findAll() except returning only 1 column from the table.

It's a choice of XML parser implementation.  JAXP is a generic
interface whereas crimson is the driver implementation.  Xerces does
both in one go.


The only reason to stick with a difficult to set up parser would be
because there is a lot of XML processing and it would have an adverse
effect on the system otherwise.  JBoss only reads a couple of XML
files so it shouldn't matter that much.


When I installed cocoon I had to remove jaxp.jar and crimson.jar and
replace it with xerces.jar.  I've noticed no difference at all.

Hmmm, I wonder why bother with crimson.jar and jaxp.jar when xerces
got it all?  Is there any particular reason for this?  I'd vote for
xerces for simplicity's sake.

Hey list,


This would be an ideal time to let people know that XDoclet version 1.0
has just come of age.  XDoclet is the successor of EJBDoclet, Rickard
Oberg's tool for automatic generation of interfaces, deployment
descriptors, and now much much more.


XDoclet 1.0 has full support for EJB2.0 and is focused on JBoss, but also
covers other EJB containers, meaning that if you find yourself in the
unfortunate position of having to stop using JBoss and use another
container all you need to do is change your ant script and some comments
in your code.  It also has support for Struts, JSP Taglibs, WebWork,
Apache-SOAP, and JMX.


Go to http://www.sourceforge.net/projects/xdoclet to get the download.

Subject: [JBoss-user] Strange problem with BMP entity bean caching -
incorrect values found by findByPrimaryKey()



Folks,



JBoss 2.4.0 with Tomcat 3.2.3
-


I have a strange problem that has completely foxed me:


The sequence of events on a BMP entity bean is as follows. All steps are
called from a client in separate transactions:


1. Bean Created


2. Bean Read
   State OK at this point


3. Bean Updated
   State written to DB OK, beans internal value object is updated OK.


4. Bean Read.
   State retrieved is state *before* update in step 3.


5  Bean Updated


6. Bean Read



The problem is that the read at (4) retrieves the bean state that was
present *before* the update at (3) was processed.


I have checked the database and the update in (3) does get written to the
DB.
I have debugged the code and the ejbStore() and ejbLoad() methods get called
as expected.


As far as I can see, the cached bean does not accurately reflect the
contents of the DB.
Its almost as if findByPrimaryKey() is getting the wrong bean instance from
the cache.



I am using commit-option A as JBoss is only thing talking to the DB.


The code that updates the bean is as follows: (Note "details" is a
ContactModel value object instance)


--
// Find Contact instance first in case it does not exist
ContactKey primaryKey = details.getContactPrimaryKey();
Contact contact = contactHome.findByPrimaryKey(primaryKey);


// Modify Bean and re-read in case DB has massaged the data
contact.modifyDetails(details);
contact = contactHome.findByPrimaryKey(primaryKey);
ContactModel updatedDetails = contact.getDetails();
---



and the ejbStore method looks like: (contactDetails is the beans internal
value object holding the bean state)


-
try
{
  setDAO();
  this.contactDetails = (ContactModel)
contactDao.update(this.contactDetails);
  modified = false;


  logger.info("contact bean stored, contactDetails = " +
this.contactDetails);
 }
 catch (DAOFinderException ex)
 {
  context.setRollbackOnly();
  throw new NoSuchEntityException(ex.getMessage());
}
catch (DAOApplicationException ex)
{
  context.setRollbackOnly();
  throw new EJBException(ex.getMessage());
}
catch (DAOSystemException ex)
{
  context.setRollbackOnly();
  throw new EJBException(ex.getMessage());
}







Does anyone have any ideas? I am completely stumped...



Thanks in advance - Adam

[JBoss-user] [URGENT] Problem while calling a method of a session bean

[Herve Tchepannou]

I have 2 beans: User (Entity) and UserCollection (Session).
In UserCollection I have the following functions:

public UserData findById( int id )
throws ObjectNotFoundException,
RemoteException
{
if ( TeamSpace.DEBUG_ENABLED )
{
m_logger.debug( "findById(" + id + ")" );
}

try
{
UserHome home = ( UserHome ) getHome( UserHome.JNDI_NAME,
UserHome.class );
User usr = home.findByPrimaryKey( new UserPK( id ) );
return usr.getData();
}
catch ( FinderException f )
{
throw new ObjectNotFoundException( "Can't find user with id:
" + id, f );
}
}

When I call this function from my test-case, I receive the following
exception:
 [test] .test.UserCollectionBeanTest.testFindById()
 [test] java.rmi.ServerException: RemoteException occurred in server
thread; nested exception is:
 [test]  java.rmi.ServerException: Load failed; nested exception is:

Does anyone knows what's wrong in my bean?

[JBoss-user] Question about JAWS table generation

[Herve Tchepannou]

Title: Question about JAWS table generation





Im using EJBDoclet v1.2 to generate my EJB files.
When I build all my files and deploy them, here are the message that are log in 'server.log':


[JAWS] Table t_user created
[JAWS] Created table 't_user' successfully.
[JAWS] Primary key of table 't_user' is 'null'.


I checked in hypersonic, and the field 'pk' is not the primary key. Why? 
Is there any xml-tag for JAWS for specifying the primary key? 


here are my deployment files:
