That are only the fluent api to create processes. I recommend you the other approach:
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( ResourceFactory.newClassPathResource("MyProcess.rf"), ResourceType.DRF ); KnowledgeBuilderErrors errors = kbuilder.getErrors(); if (errors.size() > 0) { for (KnowledgeBuilderError error: errors) { System.err.println(error); } throw new IllegalArgumentException("Could not parse knowledge."); } KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); ksession.startProcess("com.sample.MyProcess"); If you need the reference to the process instance you can do: WorkFlowProcessInstance processInstance = ksession.startProcess(...); Work 2009/11/2 Scott Stevenson <scott.steven...@datacert.com> > I read that section but I’m still not clear how to add my process > (created like the section just before) to the KnowledgeBase.
