    JBOSS EAP 6.4 - module system and "custom code"

    Pieter-Jan Remaut Newbie

      Dear JBoss developers,

       

      I'm working on JBOSS 6.4 and deploying a Java application which is packaged in an .EAR file. This is the "base product" and is deployed fine.

      I now want to use JBOSS's module system to load a library of custom Java classes to add on top of the base product. I was able to do this, however my custom code does not get included "correctly": it depends on (actually it extends) a class from the base application, inside the .EAR file. This works in e.g. WebSphere when simply putting the custom jar file in the classpath, but it doesn't seem to work here.

       

      Is there a way to get around this? Can I make the custom code "see" the base code?

       

      Relevant output of the server.log:
