    Classloader issue when invoking EJB method via JMX

    Ben Kirby Newbie

      Hi, I'm currently using AS6.final, with Weld upgraded to 1.1.1.final. EAR class isolatation is turned off. I have an EJB singleton, that I've registered with JMX - the EJB class is packaged in a JAR within an EAR. When I invoke one of the methods on this bean, via the JMX-console, I get the error at the bottom of this post.

       

      The method involves opening a transaction, as you can see from the trace. I think the general error is to do with classloading, however (see https://issues.jboss.org/browse/SEAMJMS-16); by invoking the method via the JMX-console in a browser, I'm doing it 'outside' of the EAR app which contains the EJB class.

       

      I've tried specifying scoped class loading (http://community.jboss.org/wiki/ClassLoadingConfiguration) by adding the following code (with necessary syntax changes between the files) to both the EAR jboss-app.xml and the jmx-console.war jboss-web.xm, with the same loader repo name:

       

      {code}

      <class-loading java2ClassLoadingCompliance="false">

            <loader-repository>

               my.domain:archive=myapp-ear

               <loader-repository-config>java2ParentDelegation=false</loader-repository-config>

            </loader-repository>

         </class-loading>

      {code}

       

      However this has had no effect. How can I add the classes required to the jmx-console.war class loader, if indeed this is the issue?
