Major classloader issues with multiple ear files

[sunondo]

I have two ear files which I am trying to run in JBoss 3.2.3. Each one runs fine independently. When I run both together, one of the ear files uses a Class with the same package name from the other and gives a MethodNotFoundException. After I changed the package name of the Class, the ear file started using a properties file from the other.

I have specified different jboss-app.xml files in each ear file under the meta-inf dir. I am including those below:

Ear 1:
<?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>jboss.loader:loader=suppliernet</loader-repository>
</jboss-app>

Ear 2:
<?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>jboss.loader:loader=selfreg</loader-repository>
</jboss-app>

I will really appreciate any help!


I am running JBoss on Linux.

Thanks,

Sunondo

Re-read:

http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration
http://www.jboss.org/wiki/Wiki.jsp?page=JBossClassLoadingUseCases

to understand why the jboss-app.xml should look like:

<jboss-app>
 <loader-repository>
 jboss.loader:loader=suppliernet
 <loader-repository-config>
 java2ParentDelegation=false
 </loader-repository-config>
 </loader-repository>
</jboss-app>

Also, meta-inf/jboss-app.xml is wrong. Jar files use case sensitive entries, so it may just be that the scoping is not being applies. The entry must be META-INF/jboss-app.xml.

Hi I am getting this error, when I deploy my core.ear file on Jboss 4.0 with tomcat webserver. But the same ear file when I deployed on jboss 3.0 with jetty webserver is working good.
Can any body help what should I do to get rid of this error.

The ear-file or one of the modules within it has included it's own commons-logging.jar.
Remove this and you'll get rid of this error messages.
JBoss already has commons-logging.jar on board.
