    EJB3/Jboss - binding issue.

    Bart Stanczyk Newbie

      Hi, I'm pretty new to EJB3 and I started doing this simple forum tutorial (http://www.informit.com/guides/content.asp?g=java&seqNum=239&rl=1)

      I created an EAR and put the EJBs in the EJB module and the test servlet in the Web module. It deploys without errors, but when I invoke the getForums command I get an error.

      I've been trying to fix this for about 5 days now. I hope someone can help me out here.

      I know that the problem has to do with the ForumManager session bean.

      I'm using MyEclipse 5/Eclipse 3.2 / Jboss 404 / MySQL

      -Thanks in advance

      stacktrace
