Sounds like a packaging issue - either a missing dependency or some issue with visibility of the class to the ClassLoader. Which class caused the NoClassDefFoundError exception?
Post the trace from your JBoss server.log.
thanks for you response, but seems that JSP files can not see any classes packed in the same .war file as itself.
Is that true? I have tried JBoss3.0.0+tomcat4.0.3 and JBoss3.0.0+Jetty, neither works. Actually same file structure works on Orion.
Which JBoss version right now works correctly both on ejb and web client? And where I can get it?
Any help appreciated.
