[jboss-user] [EJB 3.0] - Re: Can you Inject Local EJB from separate ear file?

[jfrankman]

Thanks for the tip. Your suggestion solved my problem. I also found that I had to change the jboss config to use callbyvalue per this article:

http://wiki.jboss.org/wiki/ClassLoadingConfiguration

Now I am almost there. I can inject the session bean and call a method, but now the object returned by the session beans method cannot be cast into my class:

NexusEventDefinition def= nexusEventsService.findNexusEventDefinitionByName("Synchronous event that does neat things.");

I get a class cast exception:

Any idea why I am getting the class cast exception?
