JBoss 4.3 to JBoss 5.1 Migration - Assembly-Descriptor Error

    Hi All,

     

    I am in the process from migrating from JBoss 4.3 to JBoss 5.1 and on starting the server with the deployed ejb, I get the following error in the server.log : org.xml.sax.SAXException: Element type "assembly-descriptor" must be declared.

     

    My jboss.xml has

     

    <assembly-descriptor>

         <security-role>

         <role-name>AdminUser</role-name>

         <principal-name>${skjgfksfgksjg}</principal-name>

         </security-role>

    </assembly-descriptor>

     

    I'd appreciate some help as to what I need to change for the migration to work ...

     

    Cheers

    Elesh
