<div class="jive-rendered-content"><p>Hello,</p><div><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've spent some time trying to figure out how to communicate with remote processes, however I need an advice from more experienced devs, how to fulfill following requirements with jBPM 5:</p><p>There is OSGI container, let's call it A.</p><p>There is JBoss EE container (different JVM, possibly different machine). It contains setup identical to jbpm demo setup. Lets call it B. </p><p>In short: I want to be able to manage processes automatically by A (start, stop, signal), while jbpm engine resided either on A or B. </p><p>- I want to have functionality as in jbpm demo setup (that is - all UI consoles working ant integrated with Guvnor repository).</p><p>- I want to be able to see process definitions in jbpm in Guvnor repository console. (it is possible in default setup).</p><p>- I want to be able to see processes in jbpm console started in gwt console. (it is possible in default setup).</p><p>- I want to be able to see process instances in gwt console initiated (started) by some remote JVM's <strong>with some data as initial context</strong> (OSGI environment specifically). (Not  possible with REST services - no way to specify initial data)</p><p>- I want to be able to <strong>signal processes WITH DATA</strong> from remote JVM's. Initiating party must be in OSGI container (Karaf) but outside of JBoss container (I cannot overcome this contraint, non-technical one). (Not  possible with REST services - no way to specify signal data)</p><p>I do not care where actually is jbpm console, jbpm task service, drools and jbpm engines are really deployed, but I prefer to stay in JBoss because it's probably most tested deployment.</p><p>What are my options to acomplish this? I can think of:</p><p>a) extend gwt-console-server with additional REST services which can start/signal processes with data and continue using REST services.</p><p>b) Try to deploy jbpm console client and server on Karaf, hope to be able to attach to the same KnowledgeBase sessions as used by jbpm console (by OSGI wiring) - and manage them from there.</p><p>c) Maybe there's a way to make signals by loading statefull session and performing signals (but I guess I would simple restore process state and it would continue to run on invocation side with process running in parralel on original container)?</p><p>d) Maybe there's a way to force jbpm to publish process management (engine or session) to JNDI, and access sessions it from remote?</p><p>e) ....?</p><p>What are my options? What is the easiest option?</p></div></div>
