Here is the code :
public static final void main(String[] args) {
try {
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
StatefulKnowledgeSession ksession2 = kbase.newStatefulKnowledgeSession();
KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newThreadedFileLogger(ksession, "test", 1000);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());
ksession2.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());
// start a new process instance
Map<String, Object> params = new HashMap<String, Object>();
params.put("employee", "krisv");
ksession.startProcess("com.sample.evaluation", params);
ksession2.startProcess("com.sample.evaluation", params);
//logger.close();
} catch (Throwable t) {
t.printStackTrace();
}
}
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("Evaluation.bpmn"), ResourceType.BPMN2);
return kbuilder.newKnowledgeBase();
}
I created two session here,when i run it ,two processinstance was created,and there are two tasks for user "krisv" http://community.jboss.org/servlet/JiveServlet/downloadImage/2-607644-16437/450-78/%E6%9C%AA%E5%91%BD%E5%90%8D.jpg
i can complete the first task successfully,and the continued tasks was created too like this:
[2011:05:149 14:05:344:debug] Arguments : [org.jbpm.task.Task@b1e211a8]
[2011:05:149 14:05:423:debug] Message receieved on client : AddTaskResponse
[2011:05:149 14:05:423:debug] Arguments : [3]
[2011:05:149 14:05:423:debug] Message receieved on client : AddTaskResponse
[2011:05:149 14:05:423:debug] Arguments : [4]
however,when i complete the second task in the above picture,the result is like this:
[2011:05:149 14:05:357:debug] Message receieved on client : GetTaskResponse
[2011:05:149 14:05:357:debug] Arguments : [org.jbpm.task.Task@ce8b1e7d]
[2011:05:149 14:05:420:debug] Message receieved on client : GetTaskResponse

[2011:05:149 14:05:421:debug] Arguments : [org.jbpm.task.Task@ce8b1e7d]
there are no AddTaskResponse,and the continued tasks can not be created.
