Can't find EJB object through @EJB annotation
---------------------------------------------

                 Key: GERONIMO-5467
                 URL: https://issues.apache.org/jira/browse/GERONIMO-5467
             Project: Geronimo
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: OpenEJB
    Affects Versions: 3.0-M1
            Reporter: LiWenQin


I deployed a war package on Geronimo-3.0,  which is in the attachment.
A Servlet uses a singleton EJB through @EJB annotation.
When the wep app invoked the Servlet, an exception appeared as below.

javax.servlet.ServletException: Error instantiating servlet class org.apache.geronimo.testsuite.ejbtest.backServlet.CalculatorServlet
