ClassNotFoundException: org.hibernate.hql.ast.HqlToken in Weblogic

Hibernate’s migration guide mentions that WebLogic uses a different version of ANTLR causing this exception.

A work around for this problem (differnet from what Hibernate mentions) is to set the “prefer-web-inf-classes” element in weblogic.xml to true.

       <weblogic-web-app>
               ....
          <container-descriptor>
              <prefer-web-inf-classes>true</prefer-web-inf-classes>
         </container-descriptor>
               ....
       </weblogic-web-app>

I encountered this problem several months ago while running under WebLogic 8.x. Interestingly, it still exists in WebLogic 10.x server.

    I have a catch-22 situation…
    I do pref-web-inf-classes=false to make my spring applicationContext work fine(otherwise linkageError with org.w3x.dom.Document
    But then i get this hibernate exception when I start app and try to login(which uses a db query)
    If do pref-web-inf-classes=true, like I said before spring app context won’t load up.
