    jndi connecting problem

    von dart Newbie

      I bind jboss to one network interface with ./run.sh -b x.x.x.x command.
      When run on the local machine, client using jndi connects correctly to the configured address, and finishes successfully. but on remote machine, exception is thrown. more over, if the code is wrapped inside servlet, though jndi context is correct, the code always connect to localhost.
      first one of the following stack trace is shown on remote machine, the second one is inside container.

          Root exception is java.lang.ClassNotFoundException: org.jnp.server.NamingServer_Stub ]]


          For this, you will have to include the jbossall-client.jar file in the classpath of the remote client application.


          For the second case, can you post the code of the servlet, where you are doing this lookup. Looks strange, the Context.PROVIDER_URL that you are passing is being ignored.




          • 2. Re: jndi connecting problem
            von dart Newbie

            No, client doesn't have org.jnp.server.* package. this class should be downloaded from server dynamically during invocation.
            I bind jboss to 0.0.0.0 interface, the servlet problem seems solved. but I get another XPath problem. I can evaluate xpath standalone, but can't in the container enviroment. some syntax is not allowed.
            this one is illegal.
            string-length(/ns3:orderOperationResponse/ns2:orderOut/clientID)>0
            this one is legal.
            /ns3:ticketsOperationResponse/ns2:ticketsOut/totalPrice>0
            strange.

            • 3. Re: jndi connecting problem
              von dart Newbie

              The first one is RMI codebase problem, but I haven't solved it.
              second one is OK now, I combined the two XPath into one, with "or".

                I opened server firewall port 8083,1099,1098 and some more. I used ethereal to capture the socket syn packets. but I find my client freezed! I've no idea.

                  I did not get this. You are using these classes for JNDI lookup from the client. So shouldn't the jar containing these class files be available in the client's classpath? Did you try adding the jbossall-client.jar in the classpath of the client application?

                  • 6. Re: jndi connecting problem
                    von dart Newbie

                    I tried to use several different method to access JNDI from remote machine, and always get problem on server.
                    The following one is what I get with JNDI over Http.
                    The InitialContext can be obtained, but look up failed.
                    if I put jbossall-client.jar on classpath the first stack trace is obtained, and if I put jbosssx-client.jar, jnp-client.jar, jboss-sercurity-spi.jar, jboss-client.jar on classpath the second stack trace is otained. Both from server side.

                    So this must be an classpath problem.

                      Did you use the same JBoss jar files which are on the server? Also, make sure you are using the same version of Java on both the server and the client.

                        sorry, I compiled jboss-5.0.0-Beta2 and used it as server, but at client side, I just installed jboss-5.0.0-Beta3. So that caused the problem.
