Invoking from Web application to a JBPM5 process

How to invoke a JBPM process from a Servlet/JSP page?  All the examples talks about the API, but the example expecting is where to mention the HOST, PORT , and the PATH to connect the JBPM Flow?

However If there are two developers one is working on JBPM5 process and deploys to server  A. and nother developer is working on Web application he deploys his web application on server B?

Now how to submit the request (or invokes the JBPM Process) from server B ?

The steps are:

1.  Build your Process in Eclipse.

2.  Register this process with Drools repository  (see how to do it in the Chapter 16 http://docs.jboss.org/jbpm/v5.3/userguide/ch.process-repository.html ).

          (Right click on   your  Evaluation.bpmn process choose  Guvnor and then add   (provide the host and port and authentication credentials.)

3. Now you can browse the to see your deployed process at  bpmn-console  http://localhost:8080/jbpm-console/

4. Also you can see the same process in the govnor  http://localhost:8080/drools-guvnor

5. Invoke the process from the Web application Copy all the process  in some folder say  html-public/jbpmflows/   (you can copy all others flows here)

6. Use the following code with the URL that you can point to the process file as a simple static file

     private static KnowledgeBase readKnowledgeBase() throws Exception {

                    KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

                    //kbuilder.add(ResourceFactory.newClassPathResource("Evaluation.bpmn"), ResourceType.BPMN2);

                    //kbuilder.add(ResourceFactory.newUrlResource("file:///D:/Evaluation.bpmn"), ResourceType.BPMN2);

                    kbuilder.add(ResourceFactory.newUrlResource(new java.net.URL("http://:8080/webcontextroot/jbpm/Evaluation.bpmn")),         ResourceType.BPMN2);

                    return kbuilder.newKnowledgeBase();

          }

7. submit your flow request to the host system where your flows were registered

      private static StatefulKnowledgeSession createKnowledgeSession(KnowledgeBase kbase) {

                    StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

                    HornetQHTWorkItemHandler humanTaskHandler = new HornetQHTWorkItemHandler(ksession);

                    humanTaskHandler.setIpAddress("127.0.0.1");  //govnor host

                    humanTaskHandler.setPort(5445); //govnor port

                    ksession.getWorkItemManager().registerWorkItemHandler("Human Task", humanTaskHandler);

                    return ksession;

          }
