Have you packaged your client code in an application client JAR within
an EAR file? You should be doing this and then running your client EAR
using 'launchClient' (in the WAS/bin directory). This will give your
client code access to all the JEE client services that it will need to
to do EJB invocations.

Hope that helps,

Mark.
