    NullPointerException on EJB invocation

    Derek Hulley Newbie

      Hi,

      JBOSS version: jboss-3.0.0_tomcat-4.0.3
      ANT version: jakarta-ant-1.4.1
      OS version: Windows XP pro

      I receive a wrapped NullPointerException that doesn't have a stack trace or an error message when attempting to invoke a method on a stateless session bean. The wrapper exception's stack trace is given below.

      I am running it using the JBOSS 'default' configuration. Unfortunately, I am unable to attach the file to this post for some reason, but if the stack trace below interests you, then email me and I will gratefully mail you the source.

      Any help would be greatly appreciated, even if it is just to say that you compiled and tested and it worked on your machine.

      Thank you in advance
      Regards
      Derek
