Hi,
I have created and process which has a Service Task.
*Start -> Servicet Task -> End*
When i run this through a java test program it *works fine*.It uses org.jbpm.bpmn2.handler.ServiceTaskHandler which is present in jbpm-bpmn2-5.1.0.Final.jar and is deployed on to the jbpm-gwt-console-server.war
public class ProcessTest {
public static final void main(String[] args) {
System.out.println("ProcessTest.main()");
try {
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");
ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());
ksession.getWorkItemManager().registerWorkItemHandler("Service Task", new ServiceTaskHandler());
System.out.println("ProcessTest.main()...executed");
// start a new process instance
ksession.startProcess("com.sample.bpmn.hello.service");
logger.close();
} catch (Throwable t) {
t.printStackTrace();
}
}
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("ServiceSample.bpmn"), ResourceType.BPMN2);
return kbuilder.newKnowledgeBase();
}
}
The issue is when i try to start the process from jbpm-console i get following erro in <jboss>\servers\default\logs\server.log,
