Se Hee -
You should narrow() for all EJB downcasting, and should not rely on
language casting. This is required in EJB1.1 - mainly for IIOP I think.
I would have expected a more meaningful stack trace than this. 2 things
you might try:
1. Check the type of the object before you cast it. I know, it's
obvious, but sometimes you think you are getting a particular type when
in fact you aren't.
2. Weblogic installs a separate classloader to load EJB components - I
think this can cause problems. Make sure you aren't getting different
versions of the class in the classpath and the EJB jar. In fact, try to
avoid having your beans in the weblogic classpath - restrict them to
dynamic loading in the weblogic.properties.
regards,
paul.
