    SINGLE ejb jar deploy gives NoClassDefFoundError!

    Zeron Newbie

      Hello All,

      Jboss 3.2.3

      I am a JBoss newbie.. 2 days only.
      I was really surprized how easy it is to deploy something under JBoss, but then things went bad.

      I'm trying to deploy a single ejb. No external dependencies.. nothing.
      It is packaged in a single jar file like this:

      mycomp/
      --- /ejb/myejb/
      --------/AAAHome.class
      --------/AAABean.class
      --------/AAA.class
      --------/AAAException.class
      --------/model/
      ----------------/Foo.class
      ----------------/Bar.class
      META_INF/
      ---ejb-jar.xml
      ---jboss.xml


      There is nothing out of ordinary in ejb-jar.xml or jboss.xml they define only one SLSB ejb.

      when I copy the provision.jar (the ejb I want to deploy) to the server/default/deploy folder, the deployment starts but fails with this exception:
