Strange problem when deploy the servlet in jboss

[calffin]

I use jboss-3.0.8 integrated with jetty as my j2ee server. I write a servlet which receive the request outside and delegate the request to the EJB which the servlet refrences. I use the remote interface of the EJB in the servlet. But the servlet is not directly with the EJB. I write a middle class as buseness delegate between them. I edit the web.xml and jboss-web.xml file which both introduce the information of the EJB refrenced.
After I copy the generated WAR file to the deploy directory, I start up the jboss server. But I find the WAR file can't be deployed. The error message is below:
Caused by: javax.ejb.EJBException: null; CausedByException is:
AccountFacadeLocal not bound
at server.web.AccountFacadeBD.(AccountFacadeBD.java:35)
at server.web.AccountFacadeBD.getInstance(AccountFacadeBD.java:43)
at server.web.Accountlet.(Accountlet.java:27)

I am surprised by the error message because I never use the local interface of the EJB. I don't know whether the servlet can refrence the local interface of the EJB in jboss-3.0.8. I see the jboss-web dtd in the docs/ directory , it only has the ejb-ref element , has no ejb-local-ref element.
Anybody can help me?
Any idea is welcome!
Thank you!
Best regards!
