Glassfish servlet and EJB bean dependency

I am using Glassfish 3.1.1 and trying to get EJB2.x deployment working before moving to EJB3. I have made a small example that is structured like this:

• EAR
  • A.jar
    • ejb-jar.xml to describe bean A, containing the remote and local interfaces.
    • the bean also contains a helper class to narrow() the home interface object.
  • B.jar
    • ejb-jar.xml to describe bean B, containing the remote and local interfaces.
    • the bean also contains a helper class to narrow() the home interface object.
  • C.war
    • web.xml contains a servlet and <ejb-local-ref> tags to point to local interface of beans A and B
    • war contains code to perform lookup of the local interface and narrow it using the helper class of the bean.

This all deploys and works fine. But when I want to move the lookup code out of the war and move it to a jar that is available under the lib/helper.jar I get a ClassNotFoundException on the narrow helper.

Caused by: java.lang.ClassNotFoundException: com.abeloos.glassfish.helper.narrow.calculator.EJBNarrow at com.sun.enterprise.loader.ASURLClassLoader.findClassData(ASURLClassLoader.java:808) at com.sun.enterprise.loader.ASURLClassLoader.findClass(ASURLClassLoader.java:696) at java.lang.ClassLoader.loadClass(ClassLoader.java:303) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:316)

It is almost as if you cannot access the bean code if you come from the lib-path.
