Classloader get wrong class between two diferent ear

[jfht]

Hi!

I have two diferent named ear (EAR1, EAR2).
In each ear I have two diferent named jars (EAR1JAR1, EAR2JAR1) in each one a diferent class with equal name.

I deploy EAR1 and then EAR2.

In EAR2WAR1, when an request is dispatched, the class X at EAR2JAR1 is requested, but the one that cames online is the one X at EAR1JAR1.

I have defined "<loader-repository>pt.isp.iol:loader=propername</loader-repository>" in jboss-app.xml for each EAR (1|2), so the class loader become diferent, but the problem stills.

The class X is a http filter, and there are some more classes that is happening the same.

How can I have independent EAR with classes that have equal names?
Thanks!

I'm not getting any answer in this topic! Am I in the wrong Forum? If yes which should I Post?

Thanks for any help!

The classes which clash, are these classes the same?
In that case it would be best that the shared library is separate library jar which is deployed before the two ears.

If the classes have clashing class names, then you really should put them in different packages.

Is there interaction bewteen the two ears? If there is, then they better have the same classloader repository as this will make your app faster. If not then defining the classloader repository should work. I assume you used two different names (this is not clear in your post). If it still does not work, check that your xml conforms to the dtd and whether there are any warnings/errors in the logs.

Both classes are diferente versions of one older.
So both classes are not the same.
There is no interaction or integration between both EARs.

Boths classes has the same package, they have the same function.
Ok, you will say that I should put them in an common jar inside the configuration lib dir. Is the objective, but now I need them as they are. This a work o two separeted dev teams... :(

I'm not clear that I defined well the classloaders. Even in the documentation I couldn't find a good explanation how to do it. I looke at google and merging both fonts I write the following two files:
------EAR1.ear/META-INF/jboss-app.xml---------------
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE jboss-app
PUBLIC "-//JBoss//DTD J2EE Application 1.3//EN"
"http://www.jboss.org/j2ee/dtd/jboss-app_3_2.dtd">
<jboss-app>
<loader-repository>pt.isp.iol:loader=GCF</loader-repository>
</jboss-app>
-----------------------------------------------------------

------EAR2.ear/META-INF/jboss-app.xml---------------
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE jboss-app
PUBLIC "-//JBoss//DTD J2EE Application 1.3//EN"
"http://www.jboss.org/j2ee/dtd/jboss-app_3_2.dtd">
<jboss-app>
<loader-repository>pt.isp.iol:loader=BO-ISP</loader-repository>
</jboss-app>
-----------------------------------------------------------

I don't get see any relevant warning besides clustering that I don't use.

Am I doing anything wrong in this xmls?
Do you know where I find better explanations to define classloaders?

Tnx

I don't know if it can work but try with:
<loader-repository>pt.isp.iol1:loader=GCF</loader-repository>
and
<loader-repository>pt.isp.iol2:loader=GCF</loader-repository>

(change the string before ":loader=")

I tried and didn't work.

For example in the doco we can read that this xml give the possibility to have diferent versions of the same code... That was the reason I used those files...

Check your jmx-console to see if you have two different classloaders created ? For e.g.
the default domains look like jboss.j2ee: and then a list of items underneath. Check if ur
pt.isp..... is also listed as a separate domain?

[jfht]

No! I don't have it!
What am I doing wrong so?

Thanks!

[jfht]

Actullay I don't have any of them!

[jfht]

What should I do to have those class loaders recognized by Jboss? Any one can help?
Thanks!

I'm searching, and I have found http://www.jboss.org/index.html?module=bb&op=viewtopic&t=29584
But the problem stills.

Any help?
