    Wierd deployment problem with MDB

    Sherman Wood Apprentice

      I have an EJB jar with a mixture of CMP 2.0 entity beans and MDBs. I am having a strange problem deploying this jar into JBoss 3.0.2.

      Here is a snippet from the ejb-jar.xml, which was generated through XDoclet.

      ....

      Somehow, the EJB-QL and the MDB class name have been concatentated!!!

      Looking at the verifier, I cannot see Section 22.2 that is being complained about.

      My second MDB, DiaryReaderBean, deploys fine. I have also had the same MDBs working without the entity beans there.


      Any ideas?

      Thanks,
