    Problem accessing JBOSS 5 server from remote clients on different subnets.

    Shail Tawde Newbie

      Hi,

      I am migrating my appllication from JBoss 4.2.2.GA server to Jboss 5.1.0.GA.

      In the application, we employ Java Messaging Services (JMS), for dynamically updating/refreshing information on the GUI.

       

      Everything seems to be working fine on the local machine as well as remote clients accessing the server but on the same subnet. The issue arises with clients(remote) on a different subnet accessing the server.

      E.g. A client with IP 192.168.0.20 accessing the JBoss server machine with IP 192.168.20.20

      The application launches successfully but the dynamic refresh of information does not happen. Java console logs show errors in setting up of JMS connection.

      My Jndi.prop and JBoss.prop files are as follows:

      Jndi.prop:

      java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory

      java.naming.provider.url=jnp://localhost:10990

      java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

       

      JBoss.prop:

      JBOSS.NAMING.PORT=10990

      JBOSS.NAMING.RMIPORT=10980

      JBOSS.INVOKER.RMIOBJECTPORT=4444

      JBOSS.INVOKER.SERVERBINDPORT=4445

      JBOSS.CONNECTOR.SERVERBINDPORT=4446

       

      We had encountered similar problems on JBoss 4.2.2.GA version but setting up the following property it got solved.

      -Djava.rmi.server.hostname=<SERVER_IP_ADDRESS>

      This does not seem to work with JBoss 5.

      I start my application server using the following command:

      "%JAVA%" %JAVA_OPTS% "-Djava.endorsed.dirs=%JBOSS_ENDORSED_DIRS%" -classpath "%JBOSS_CLASSPATH%" org.jboss.Main -c pvng -b 0.0.0.0 -P "%JBOSS_HOME%\server\pvng\conf\jboss.properties" %*

       

      Ours is a networking based project and hence accessing the server from remote clients on different subnets is imperative.

      Can anyone please suggest a solution for this or atleast some workaround? Any help is highly appreciated.

       

      Thanks in advance
