            First of all this info is not sufficient atleastfor me to tell whats wrong.
            Now is that happening at deployment time or when yr client make a call.

            My suspicion is that something wrong with Deployment Descriptors in ejb-jar.xml or jboss.xml.

            Do specify, when it is happening and post yr lookup string and Deployment descriptors so that it can be verified whats happening.

              client code:
              InitialContext ic = new InitialContext();
              DemoHome home = (DemoHome)javax.rmi.PortableRemoteObject.narrow(ic.lookup("RingRemote"), DemoHome.class);
              Demo v = home.create();

              file list:

              my ejb-jar.xml :
              <?xml version="1.0"?>
              <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">



              my jboss.xml:
              <?xml version="1.0" encoding="UTF-8"?>
              <!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.0//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd">

                Now, yoou still haven't specified when this error is hapening.
                Can you deploy yr bean suceesfully.
                My gusess is it is happening when u are invoking call from client.
                Secondly I noticed in yr descriptors that you are using DAO class to access DB.
                And by the looks of it, Yr bean implementation and DAO implementation are in the same class.

                Now, In case of DAO, U need descriptors for DB datasopurce u are going to use, which hasn't been specified in yr decriptors.


                <resource-ref >


                Similarly, in jboss.xml


                Now, I have just used these names which are mapped in
                standardjbosscmp-jdbc.xml, which uses Hypersonic DB,
                if you are using other DB, then u might have to create a file for taht and then use these mappings for that.

                Now,other then that, I dont see anything wrong with yr Descriptors.
                But if u are still unsuccesful, do post yr log messages form server.log

                  Sorry , I'm stupid!!
                  You get it , It's happening invoking from client.
                  It's for jboss3.0.4 is succesful!!
                  But that for jboss3.2.1 then unsuccesful!
                  About your decriptors , I was tried it!Still unsuccesful!!

                      Now, Yr client looks to me is either a servelt or a jsp page.
                      as u are trying to deploy a .war file. Thats ok.

                      I am not sure at what port does naming servise listens in 3.0.4 but in 3.2.1 it is port no 1099. I am assuming they are same,even if they are not then shouldn't make any difference.
                      But one thing is when u lookup from client to get context which port no do u specify, is it same as what is it in jboss-service.xml file.

                      Code Snippet.
                      Hashtable props = new Hashtable();

                      props.put(InitialContext.PROVIDER_URL, "jnp://");
                      InitialContext initialContext = new InitialContext(props);

                      Have a look at yr jboss-service.xml file, if the port nos are same first.
                      Secondly compile yr src code in jboss3.2.1 again. and then deploy yr war file.
                      And if you still can't make it just attach yr web module and servlets in zip file and I will have a look at it.

                        I check jboss-service.xml , Port is 1099 that's right!!
                        I was tried for your provide code too!
                        Still unsuccesful!!
                        well..............this is a big problem!!

                        Could you provide a simply Stateless bean for me!
                        let me try it!!

                        thanks a lot for your help!^_^

                          Are you sure ur bean deployed without errors? Check the logs to see if there is no deployment error.
                          If thats okay, go to http://localhost:8080/jmx-console
                          and click on the jndiview link. You should see "RingRemote" as one of the JNDI names there. Basically all ur JNDI names for all apps that u deployed shud show up. Check if this shows up in JNDIView.

                            Oh~~my goodness , I'm can's find JNDI "RingRemote"~!!
                            I was tried that again!!
                            What answer ?Give you guess!

                            that be ok!!^_^ I'm very happy!

                            thanks a lot for vashistvishal and raja05 !!

                              Hi! I tried a sample EJB deployment and used the following as my environment. J2sdk1.4.1, JBoss3.0.8 with tomcat 4.1.24, J2SDk1.3.2EE for the ejb jars. I had a few problems with deploying the EJB on Jboss 4 with Tomcat4.1.24. But when i tried to deploy it on Jboss3.0.8, the deployment worked fine. At deployment it gave me a couple of warnings:

                              I assume it is deployed and it shows up in the jmx-console. When i then start my client, it gives me an error saying "javax.naming.NameNotFoundException: HelloWorld not bound". i do not have a jboss.xml file. I have a ejb-jar.xml which is as follows:

                                I jus' read somewhere that the jboss.xml file is to be part of the META-INF directory so i have appropriately added the file there with the following content:


                                But it hasn't changed the result. Please help.

                                  I made the correction and changed the ejb-name "Hello" to HelloWorld in the ejb-jar.xml . I also then made the HelloWorldMyClient call the remote interface HelloWorld in the jndiContext.lookup() method. But it still doesn't work right giving the same error that HelloWorld not bound.
