What we are trying to implement is a startProcess() method. The objective of this method is to contact the runtime engine and “tell it” to start a given process, without using REST. So far we have gotten to these point. KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.+newKnowledgeAgentConfiguration+(); KnowledgeAgent kagent = KnowledgeAgentFactory.+newKnowledgeAgent+("testKAgent", aconf);     String fileName = "/home/n1w3/Downloads/ChangeSet.xml"; kagent.applyChangeSet(ResourceFactory.+newFileResource+(fileName)); KnowledgeBase kbase = kagent.getKnowledgeBase(); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); Collection<ProcessInstance> c = ksession.getProcessInstances(); System.+out+.println(c.size()); kbase = kagent.getKnowledgeBase(); *for* (Process process: kbase.getProcesses()) { System.+out+.println("Loading process from Guvnor: " + process.getId()); }   ksession.getWorkItemManager().registerWorkItemHandler("Human Task", *new* WSHumanTaskHandler()); //StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();            ProcessInstance processInstance = ksession.startProcess("com.temenos.bpmn.CustomerOnBoarding"); System.+out+.println(processInstance.getId()); These peace of code, lets us fetch the processes that are in guvnor and then start a new process. The problem with it, is that I have to maintain my session open so that the process gets orchestrated. If I stop the program, the process does not get orchestrated. The objective we are trying to obtain is something like a “fire and forget” approach where we say start process and the runtime engine orchestrates it. Can anybody help us out with this one? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/622419#622419] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

These processes have to be accessed and started, as a result orchestrated, by the jbpm engine. You have two choices, 1. Use your own instance of the engine with your own configuration etc ( for example the code you have posted). 2. Use 'jbpm-gwt-console-server, which is a web application having all code and configurations needed for the jbpm engine to run. I understand that whatever the approach, you want a "fire and forget" solution. Such a solution is achieved by running an application as a service (i.e. run constantly and listen on a port of your system - not very nice) or as a server (i.e. create web application and deploy on an application server like jboss - then you have to use http calls to communicate with it - i.e. web services). Approach 2 above is ready out of the box (you have the engine running on a server and the communication methods - REST API - ready for you)  and you have to communicate via REST. p.s. whatever the approach you will be getting all your definitions and resources from the repository of Guvnor -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/623477#623477] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

I will be looking into the REST framework to achieve this.
