    ESB remote invoking from different AS

    arny3k86 Jan 11, 2010 7:52 AM

      Hi,

       

      We have currently a setup, where under one JBoss AS there is an ESB project, and a Seam project. We can access the ESB methods with the ServiceInvoker. We would like to separate these project into different AS-es, running in different machines. However, we can't find any tutorial, configuration example, or something that we could start out with, on how to call the ESB methods from a different AS.

       

      We are using jboss-5.1.0.GA and jbossesb-4.6.

       

      According to the Programmers Guide, we need a set of jars and the jbossesb-properties.xml in the classpath. However, it is not detailed, what to set up in that XML. Is there any example, or tutorial for this? I'm stuck with googling.

       

      Thanks in advance

          One way to obtaining this would be to let the servers share juddi.

          In this scenario the service invoker will be able to invoker services on other servers.

           

          To do this let the servers use the same database - configured in jbossesb.sar/juddi-ds.xml

            This is really no different from setting up an external client, in the same manner as the quickstart tutorials.  IIRC, many of them boot the server then invoke some client in a separate VM, which uses the ServiceInvoker to deliver the message to the ESB.  You need to expose JUDDI so that it can be queried from outside the AS via a webservice(I think it comes out of the box like this, actually).  Then you need to setup the client to use the org.apache.ws.scout.transport.AxisTransport via the client's jbossesb-properties.xml file.  Having them share the JUDDI DB is a bad idea due to concurrency concerns, in my opinion, and probably won't work well in development where each developer's JBoss may be using Hypersonic (w/out TCP listeners) for the JUDDI persistence.

             

            My suggestion is to start with a custom client jboss-esb-properties.xml file (set the AxisTransport and accompanying properties) and add JARs from deployers/esb.deployer/lib to the classpath.  This will bloat your classpath, but once you have it working, you can pare-out all of the unnecessary items like milyn.

             

            Don't forget to set this once in your client JVM, either by the code shown here, -D on the command line, or by properties-service.xml

            System.setProperty("javax.xml.registry.ConnectionFactoryClass",
            "org.apache.ws.scout.registry.ConnectionFactoryImpl");

             

            This sort of leads me to wonder why there is not a jbossesb-client.jar, in the style of $JBOSS_hOME%/client/jbossall-client.jar which includes all necessary classes for communicating with an ESB outside the app container.

              Hi,

               

              Try this jbossesb-properties.xml - change localhost to your remote AS address.

                I am using your jbossesb-properties.xml, but I am getting this exception:

                So I went to Jboss's jmx-console in particular to Global JNDI Namespace, and I found:

                  +- juddiv3 (class: org.jnp.interfaces.NamingContext)
                  |   +- UDDIPublicationService (class: org.apache.juddi.rmi.UDDIPublicationService)
                  |   +- UDDICustodyTransferService (class: org.apache.juddi.rmi.UDDICustodyTransferService)
                  |   +- UDDISubscriptionListenerService (class: org.apache.juddi.rmi.UDDISubscriptionListenerService)

                  |   +- UDDIInquiryService (class: org.apache.juddi.rmi.UDDIInquiryService)
                



                These are different to the services in your jbossesb-properties.xml. This might explain the InquiryService not bound message in the exception.
                After replacing the InquiryService for the one shown in my JNDI, I've got inquire method not found error. I am using jbossesb-server-4.7, and it seems other things are required to successfully access the UDDI via RMI. 
                Help will be much appreciated.

                  Hi,

                   

                  I have exactly the same problem. When I change the InquiryService to the one that matches my JNDI entry (juddiv3/UDDIInquiryService) I get a NullPointerException:

                  Edit: The NullPointerException occurs if I omit the request parameter (?org.apache.juddi.registry.rmi.Inquiry#inquire) in the URL. If I fill it in, I get a ClassNotFoundException for org.apache.juddi.registry.rmi.Inquiry instead.

                   

                   

                  Is there a solution for this problem?

                  How did you fix it?

                   

                  Thanks!

                      Well, I finally got it working now!

                       

                      The trick is to set everything to "LocalTransport" in the jbossesb-properties.xml. Then, you have to provide a second config file META-INF/uddi.xml. In this file, you can specify the RMI transport settings. This seems to work with juddi-client 3.0.1 .
