            Do you see any errors in log/server.log?
            I think nobody is responding because the error you
            report is too general.

            Regards,

                It looks like you've got a NullPointerException
                somewhere in validateUser().

                  adrian,
                  the problem is coming when iam looking for BMPlocalhome from a statelesssession bean.

                  so the exceptions are generated from the catch method for the try where iam looking my bMP home.
                  they are not from my validateUser() method.

                  well i read some where from forum that container is looking runtime exception as EJBException thats why it is showing statelesscontainer invoke return exception.
                  but how can i solve this??
                  i think it is the error while looking the LocalHome.

                    Can you post the code and deployment descriptors?
                    You don't need to post everything, just the relevant
                    sections.

                        Hi,

                        Your immediate problem is setting customer to null
                        before using it.

                        Also, you haven't specified a <local-jndi-name> in
                        jboss.xml

                        I think it defaults to local/<ejb-name> when you
                        don't specify it?

                        Regards,
                        Adrian

                          adrian ,
                          i changed the code as u said ,i am not making my customer as null.but again it is giving me problem
                          if you have any ejb-jar.xml and jboss.xml syntax please do post.
                          i don't think it is the problem with making the local as null.there iam just declaring it and initialinzing it.

                            If you look at the other post
                            http://main.jboss.org/thread.jsp?forum=47&thread=10656

                            That has a session bean with a local interface.

                            In general local interfaces aren't really required in
                            JBoss unless you turn set to False in
                            standardjboss.xml. JBoss automatically does local
                            processing for you.

                            Regards,
