[jboss-user] [Installation, Configuration & Deployment] - JBoss JAXB class loading problem

Hello!

I am using JAXB 2.0 on a JBoss 4.0.4GA server. The problem is, that JBoss is choosing the wrong (v1.x) JAXB classes that are part of "jboss-j2ee.jar".

How can I get JBoss to load the JAXB classes ("javax.xml.bind...") from the 
jars in the .ear-archive (jaxb-api.jar, jaxb-impl.jar and so on) INSTEAD of loading them from jboss-j2ee.jar?

I read "JBossClassLoadingUseCases"
(http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossClassLoadingUseCases)

 and "ClassLoadingConfiguration" (http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration)

 in the JBoss Wiki, but don't get the application run correctly.

As soon as I add the following code in META-INF/jboss-app.xml:

  | <jboss-app>
  |    <loader-repository> 
  |    javax.xml.bind:loader=foobar.ear
  | 	   <loader-repository-config>
  | 		   java2ParentDelegation=false
  | 	   </loader-repository-config>
  |    </loader-repository> 
  | </jboss-app>
  | 

I get errors like


  | 14:02:34,148 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.util.OnlyOnceErrorHandler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" variable.

How can I simply tell JBoss to load all javax.xml.bind.* classes from the JAXB2.0-jars in the ear, not from the old jboss4.0.4/server/default/lib/jboss-j2ee.jar AND to leave other class loading mechanisms untouched (like for log4j and so on)?

Any help would be appreciated.
