Atul:

I have absolutly no idea if this will be useful or not - but for what it's worth, I found the following fragment of code under a samples package.

I've hilighted the lines that may help.
> package org.jbpm.bpmn2;
> import org.drools.KnowledgeBase;
> import org.drools.builder.KnowledgeBuilder;
> import org.drools.builder.KnowledgeBuilderFactory;
> import org.drools.builder.ResourceType;
> import org.drools.io.ResourceFactory;
> import org.drools.runtime.StatefulKnowledgeSession;
> import org.jbpm.bpmn2.xml.XmlBPMNProcessDumper;
> import org.jbpm.ruleflow.core.RuleFlowProcess;
> import org.jbpm.ruleflow.core.RuleFlowProcessFactory;
> public class ProcessFactoryTest extends JbpmJUnitTestCase {
>  
>  public void testProcessFactory() {
>   RuleFlowProcessFactory factory = RuleFlowProcessFactory.createProcess("org.jbpm.process");
>   factory
>    // header
>    .name("My process").packageName("org.jbpm")
>    // nodes
>    .startNode(1).name("Start").done()
>    .actionNode(2).name("Action")
>     .action("java", "System.out.println(\"Action\");").done()
>    .endNode(3).name("End").done()
>    // connections
>    .connection(1, 2)
>    .connection(2, 3);
>   RuleFlowProcess process = factory.validate().getProcess();
> *  KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();*
> *  kbuilder.add(ResourceFactory.newByteArrayResource(*
> *      XmlBPMNProcessDumper.INSTANCE.dump(process).getBytes()),* 
> *      ResourceType.BPMN2);*
> *  KnowledgeBase kbase = kbuilder.newKnowledgeBase();*
> *  StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();*
> *  ksession.startProcess("org.jbpm.process");*
>  }
> 

Please let me know how this goes. 

If it works then it needs to be included in the User's Guide (or perhaps an equivalent that uses a nice utility method that keeps some of the noise out of the picture).

Cheers, Steve.
