<classloading xmlns="urn:jboss:classloading:1.0"+ +              name="test.war"   + +              domain="test"+ +              parent-first="false"+ +              export-all="NON_EMPTY"+ +              import-all="true">+ +    </classloading>+ *It helped to solve above mentioned excpetion.And because of this configuration I got rid of the Original Exception also which has been posted in very first post.* *          Thanks for all..*        But because of this configuration I got another deployment Exception.I am posting this stack trace too.

      I observed that *%JBOSS_HOME% \common\lib\hibernate-entitymanager.jar* is getting conflicting with *WEB-INF\lib\hibernate-entitymanager-3.6.3.Final.jar*        But how is this possible eventhough I have set *+domain="test"+* .        Is My observation Correct ?        Please correct me If I am doing mistake . -------------------------------------------------------------- Reply to
