    why is my LocalBean not bound?

    D D Newbie

      Hi,

      i have a problem working with a LocalBean that i call from a servlet.

       jndi = new InitialContext();
      WiseSessionHomeLocal localHome = (WiseSessionHomeLocal) jndi.lookup("java:comp/env/WiseSessionHomeLocal"); //load the bean
      


      The log says that the name of my bean is not bound - but everything is ok considering the jboss-web.xml and ejb-jar.xml:

      <?xml version="1.0"?>
      
       <jboss>
       <enterprise-beans>
      
       <session>
       <ejb-name>WiseSessionBean</ejb-name>
       <local-jndi-name>WiseSessionHomeLocal</local-jndi-name>
       </session>
      
       </enterprise-beans>
      
       </jboss>
      


      <session>
       <ejb-name>WiseSessionBean</ejb-name>
       <local-home>beans.session.WiseSessionHomeLocal</local-home>
       <local>beans.session.WiseSessionLocal</local>
       <ejb-class>beans.session.WiseSessionBean</ejb-class>
       <session-type>stateful</session-type>
       <reentrant>false</reentrant>
       <cmp-version>2.x</cmp-version>
       <abstract-schema-name>WiseSession</abstract-schema-name>
       <security-identity><use-caller-identity/></security-identity>
      </session>
      


      is this a problem depending on jboss? I am using version 4.0.0

      Thanks for any suggestions how to solve this problem.

          You are trying to lookup the bean in the local namespace of the web application, you need to add an ejb-local-ref in the web.xml of your web application.

            ok, i did add the following in the web.xml:

             <ejb-local-ref>
             <ejb-ref-name>WiseSessionHomeLocal</ejb-ref-name>
             <ejb-ref-type>Session</ejb-ref-type>
             <local-home>beans.session.WiseSessionHomeLocal</local-home>
             <local>beans.session.WiseSessionLocal</local>
             <ejb-link>WiseSessionBean</ejb-link>
             </ejb-local-ref>


            But when i deploy the log tells me a NamingException:
            ejb-local-ref: "WiseSessionBean", with web.xml ejb-link: "WiseSessionBean" failed to resolve to an ejb with a LocalHome.

            As you can see above the <ejb-link> value is the same as the <ejb-name> value in ejb-jar.xml, shown in my first post.

            what´s the problem and how to solve it?

            Thanks for any suggestions.

              Are your two archives packaged in an ear or are both archives deployed intependently?

                the .jar and .war are both contained in the same ear file.

                Any ideas how to solve this?

                  ok, i change the following:

                  now:

                  <ejb-ref-name>WiseSessionBean</ejb-ref-name>
                  <ejb-link>WiseSessionHomeLocal</ejb-link>
                  

                  i had it just the other way round...


                  also i added this to the jboss-web.xml
                  <ejb-local-ref>
                   <ejb-ref-name>WiseSessionBean</ejb-ref-name>
                   <local-jndi-name>WiseSessionHomeLocal</local-jndi-name>
                   <ejb-link>WiseSessionBean</ejb-link>
                   </ejb-local-ref>
                  


                  deployment works, but when i run the application the log says:

                  javax.naming.NameNotFoundException: WiseSessionHomeLocal not bound.

                  What´s wrong?

                    If you are using <ejb-link> and the jar and war are in the same ear you do not need to add the <ejb-local-ref> to the jboss-web.xml - Just leave this out and the name of the bean will be used to locate it.

                    Are you getting any other errors on deployment, I have just noticed that you have a number of CMP specific elements within your session bean declaration that should not be there.

                      is the name of my jar where i put the bean classes in, of importance?

                        ok, here are all the relevant deployment descriptors - updated:

                        part of ejb-jar.xml

                         <session>
                         <ejb-name>WiseSessionBean</ejb-name>
                         <local-home>beans.session.WiseSessionHomeLocal</local-home>
                         <local>beans.session.WiseSessionLocal</local>
                         <ejb-class>beans.session.WiseSessionBean</ejb-class>
                         <session-type>Stateful</session-type>

                         </session>
                        


                        jboss.xml:
                         <jboss>
                         <enterprise-beans>
                        
                         <session>
                         <ejb-name>WiseSessionBean</ejb-name>
                         <local-jndi-name>WiseSessionHomeLocal</local-jndi-name>
                         </session>
                        
                         </enterprise-beans>
                        
                         </jboss>
                        


                        part of web.xml:
                         <ejb-local-ref>
                         <ejb-ref-name>WiseSessionHomeLocal</ejb-ref-name>
                         <ejb-ref-type>Session</ejb-ref-type>
                         <local-home>beans.session.WiseSessionHomeLocal</local-home>
                         <local>beans.session.WiseSessionLocal</local>
                         <ejb-link>WiseSessionBean</ejb-link>
                         </ejb-local-ref>
                        


                        Deployment works fine, but as soon as my servlet runs, trying to call up the bean it tells me again:
                        javax.naming.NameNotFoundException: WiseSessionHomeLocal not bound.

                          it works...i typed WiseSessionLocalHome instead of WiseSessionHomeLocal.

                          Thanks for your good advices!
