    $Proxy146 cannot be cast to servlet... Access ejb bean from

    int2

      Hi,
      Thank you for read my post,
      I'm new to ejb 3.0, there's a problem when I try to access an example session bean from servlet. Anyone please help :-)
      The code of the test session bean is:

      BLocal.java

       import ...;
       @Local
       public interface BLocal{
       public String Say(String s);
       }
      

      BBean.java
       import ...
      
       @Stateless
       public class BBean implement BLocal{
       String Say(String s){
       return "hello " + s;
       }
       }
      


      And the servlet,

       Context ctx = new InitialContext();
       BLocal b = (BLocal)ctx.lookup("BBean/local");
       out.println(b.Say(" world"));
      



      For the class Blocal in servlet, I just copy it from the session bean above (remove annotation)

      When I run the servlet, I get the result:

       ype Exception report
      
      message
      
      description The server encountered an internal error () that prevented it from fulfilling this request.
      
      exception
      
      java.lang.ClassCastException: $Proxy146 cannot be cast to servlet.Bean1Local
       servlet.S.processRequest(S.java:49)
       servlet.S.doGet(S.java:70)
       javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
       javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
       org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
      
      note The full stack trace of the root cause is available in the Apache Tomcat/5.5.20 logs.
      


      If the servlet and the session bean is inside an EAR, the servlet worked fine. But if the two project (servelet, session bean) deploy separately then I got the error above.
      Anyone can help ?

      Thank you a lot and regards
