    Newbie: (MDB) DeploymentException: expected one home tag

    Kevin Knox Newbie

      I'm having a lot of fun, as witnessed by my newest bald patches. I have successfully deployed a message driven bean to JBoss, and a worker bean in the pattern of the HelloListener example, or pretty close to it.

      When I deploy the .ear containing the .war, though, I get the above mentioned error. [DeploymentException: expected one home tag]. I don't know how to interpret this error. The obvious conclusion is that the deployer wants to see a interface tag in the ejb-jar.xml, but an MDB doesn't have one that I am aware of. (Happy to be educated about this as well, though)

      If I ignore the error, everything functions exactly as I wish it to.

      What should I do?

      Thanks,

      Kevin

          Is it now your worker bean it is comlaining about?

            The complaint is unchanged by the addition or subtraction of the worker bean. I installed the MDB first all by itself, and received this error. I then stuck in some dummy interface statements, and that didn't help. I took them out. I then installed the worker bean stuff and got it working. In all circumstances, the error has been exactly the same.

            It seems to be a problem in the descriptor of the MDB, but one that I cannot begin to guess. Thanks for your reply,

              Its probably the ejb-ref home stuff it barks on. But why I really do not know.

                Thanks for looking at it. Unfortunately, the DeploymentException existed before the PIAS... bean ever needed to reference the Xform... bean.

                I don't know what the problem is, but stack trace or no, the product is working.

                Thanks,

                  I'm also a newbie having a similar problem, why is is it complaining about a home or remote interface for a mdb? Is your's complaining but working? "but stack trace or no, the product is working", mine wont deploy the ear file. ejb-jar.xml extract:

                  <container-transaction>

                  <ejb-name>OrderMessageBean</ejb-name>

                  <method-param>javax.jms.Message</method-param>
                  </method-params>
