    EJB in EAR can NOT be accessed from remote client!

    xiang yingbing Master

      Dear all,

                  I studied jboss-as-quickstarts-7.1.1.CR2\ejb-remote carefully and I can access the EJB bean from remote client successfully.

                  But, after I put the ejb jar in an ear, and the jndi name follow the syntax:

                       ejb:<appName>/<moduleName>/<distinctName>/<beanName>!<viewClassName>?stateful

                   I got an exception which will be described bellow.

       

       

                    I tried new jndi syntax(from https://community.jboss.org/wiki/JBoss7AndEjbRemoteCallWithSecurity):

                         java:<appName>/<moduleName>/<distinctName>/<beanName>!<viewClassName>?stateful

                   I still got an exception which will be described bellow.

       

       

      1. pure EJB jar test

       

      1.1 ejb jar structure

       

      [-]nms-server-ejb.jar

          import.sql

          [-]META-INF

              MANIFEST.MF

              beans.xml

              persistence.xml

          [-]com

              [-]ybxiang

                  [-]nms

                      [-]server

                          [-]ejb

                              [-]session

                                  ISecuredRemoteSession.class

                                  SecuredRemoteSession.class

       

      Please ignore the beans.xml and persistence.xml. They have nothing to do with our discussioin.

       

       

       

       

      1.2 code

      (a) ISecuredRemoteSession.java

       

      package com.ybxiang.nms.server.ejb.session;

      public interface ISecuredRemoteSession {

          int add(int a, int b);

          int subtract(int a, int b);

      }

       

      (b) SecuredRemoteSession.java

      package com.ybxiang.nms.server.ejb.session;

      import javax.ejb.Remote;

      import javax.ejb.Stateless;

       

      @Stateless

      @Remote(ISecuredRemoteSession.class)

      public class SecuredRemoteSession implements ISecuredRemoteSession{

          @Override

          public int add(int a, int b) {

              return a + b;

          }

       

          @Override

          public int subtract(int a, int b) {

              return a - b;

          }

      }

       

       

       

      1.3 deploy and start JBoss AS 7

      after nms-server-ejb.jar is thrown in jboss-as-7.1.1.Final\standalone\deployments, I start the JBoss AS with command:

      standalone.bat -b 192.168.1.100

       

       

       

       

       

      1.4 client code

      I modified RemoteEJBClient according to https://community.jboss.org/thread/177302?start=0&tstart=0, so client does NOT need boss-ejb-client.properties

          }   

      }

       

       

      1.5 run client

      I put jboss-as-7.1.1.Final/bin/jboss-client.jar in client class path, Now I run the client successfully with bellow log:

      other files have nothing to do with the EJB access, please ignore them.

       

       

       

       

       

      2.3 deploy

      Now, I remove nms-server-ejb.jar from jboss-as-7.1.1.Final\standalone\deployments and put nms-server-ear.ear in jboss-as-7.1.1.Final\standalone\deployments.

      From bellow log, we can see that the ear is deployed successfully:
