Thanks a lot for sending me the sample app. I will run in the environment which u said(jboss 4.0.5 +JBP 2.6.1). Now i am using jboss portal 2.6.2 bundled version(jboss 4.2.1+ jboss portal) But after deploying your app in my environment, I get the same exceptions(which i posted earlier) as in my app. can your app be run perfectly in my environment?
