I'm trying define a process dynamically with Process API. I want to insert a variable into my actionNode so, I create a HashMap and I use kcontext.getVariable(). Now I get my variable into my actionNode and I can use it. Then I want to modify (or create a new variable) my variable and its value. I don't know how to modify it and use kcontext.setVariable(); also I dont know how to recover that value in my java code. Here my code                     HashMap<String, Object> processParameters = new HashMap<String, Object>();                     KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();                     RuleFlowProcessFactory factoryP1 = RuleFlowProcessFactory.createProcess("org.jbpm.Process1");                     // My variable and value                     processParameters.put("result",5);                     factoryP1.name("Process1").version("1.0").packageName("org.jbpm")                               .imports("java.util.HashMap")                               // creating a new var                               .variable("resultReceived", new ObjectDataType("java.lang.Integer"))                                         .startNode(1).name("Start").done()                                         .actionNode(2).name("Action")                                         // I receive my variable from java Code with kcontext.getVariable                                         // and modify its value (now:6)                                         .action("java",          "resultReceived = (Integer) kcontext.getVariable(\"result\")+1;" +                                                             "System.out.println(resultReceived);" +                                         // I put my new variable with kcontext.setVariable                                                             "kcontext.setVariable(\"resultReceived\", resultReceived);").done()                                         // another actionNode.                                         .actionNode(3).name("Action")                                         .action("java","System.out.println(\"Another Node \");").done()                                         .endNode(4).name("End").done()                                         // Connections                                         .connection(1, 2)                                         .connection(2, 3)                                         .connection(3, 4);                     RuleFlowProcess process1 = factoryP1.validate().getProcess();                     kbuilder.add(ResourceFactory.newByteArrayResource(                                         XmlBPMNProcessDumper.INSTANCE.dump(process1).getBytes()),                                         ResourceType.BPMN2);                     KnowledgeBase kbase = kbuilder.newKnowledgeBase();                     StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();                     ProcessInstance processInstance = ksession.startProcess("org.jbpm.Process1",processParameters);                     // and now... How can I get resultReceived from actionNode??? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779611#779611] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
