taskResults.put("nsau_insured_name", "Raju");

}
but when I try to make this workflow group driven i.e. based on groupID task would be distributed among users, it just bombs.
Following is the approach which i used:
1) first i load the task service using the following code:
@Before
public void setUp() throws Exception {
// Compiles and persists all the .bpmn resources
ds1 = new PoolingDataSource();
ds1.setUniqueName("jdbc/testDS1");
ds1.setClassName("org.h2.jdbcx.JdbcDataSource");
ds1.setMaxPoolSize(3);
ds1.setAllowLocalTransactions(true);
ds1.getDriverProperties().put("user", "sa");
ds1.getDriverProperties().put("password", "sasa");
ds1.getDriverProperties().put("URL", "jdbc:h2:mem:mydb");
ds1.init();
emf = Persistence
.createEntityManagerFactory("org.jbpm.persistence.jpa");
env = KnowledgeBaseFactory.newEnvironment();
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
env.set(EnvironmentName.TRANSACTION_MANAGER,
TransactionManagerServices.getTransactionManager());
System.setProperty("java.naming.factory.initial",
"bitronix.tm.jndi.BitronixInitialContextFactory");
emfTask = Persistence.createEntityManagerFactory("org.jbpm.task");
taskService = new TaskService(emfTask,
SystemEventListenerFactory.getSystemEventListener());
taskSession = taskService.createSession();
MockUserInfo userInfo = new MockUserInfo();
taskService.setUserinfo(userInfo);
this.fillUsersAndGroups(taskSession);
// server = new MinaTaskServer(taskService);
taskServer = new HornetQTaskServer(taskService, 5446);
Thread thread = new Thread(taskServer);
thread.start();
System.out.println("Waiting for the HornetQTask Server to come up");
while (!taskServer.isRunning()) {
System.out.print(".");
Thread.sleep(50);
}
TaskClient taskClient = new TaskClient(new HornetQTaskClientConnector("client 1",
new HornetQTaskClientHandler(SystemEventListenerFactory
.getSystemEventListener())));
this.client = new TaskClientWrapper(taskClient);
this.client.connect("127.0.0.1", 5446);
}
2)then ran the following test case:
@Test
public void taskAssignedToGroup() throws InterruptedException {
UserTransaction ut = null;
try{
KnowledgeBase kbase = this.createKnowledgeBase();
ut = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");
ut.begin();
session = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null,
env);
new JPAWorkingMemoryDbLogger(session);
KnowledgeRuntimeLoggerFactory.newConsoleLogger(session);
CommandBasedHornetQWSHumanTaskHandler wsHumanTaskHandler = new CommandBasedHornetQWSHumanTaskHandler(
session);
wsHumanTaskHandler.setClient(client.getTaskClient());
session.getWorkItemManager().registerWorkItemHandler("Human Task",
wsHumanTaskHandler);
String document_id = "3002001";
String task_name = "Index";
String insured_name = "Tushar";
String acct_action_needed = "false";
Map<String, Object> inputVariables = new HashMap<String, Object>();
inputVariables.put("document_id", document_id);
inputVariables.put("task_name", task_name);
inputVariables.put("insured_name", insured_name);
inputVariables.put("acct_action_needed", acct_action_needed);
ProcessInstance process = session.createProcessInstance("NS_UW_WorkFlow",
inputVariables);
session.insert(process);
long processInstanceId = process.getId();
WorkflowProcessInstance processInstance = (WorkflowProcessInstance) session.startProcessInstance(processInstanceId);
System.out.println("processInstance.getNodeInstances().iterator().next().getNodeName() : " + processInstance.getNodeInstances().iterator().next().getNodeName() );
System.out.println("processInstance.getNodeInstances().iterator().next().getVariable(\"document_id\") : " + processInstance.getNodeInstances().iterator().next().getVariable("document_id") );
Thread.sleep(2000);
// For Tushar
List<TaskSummary> tasks = client.getTasksAssignedAsPotentialOwner(
"tushar", "en-UK", this.getTestUserGroupsAssignments().get("tushar"));
Assert.assertEquals(0, tasks.size());
// Pass the user and the group it belongs
client.claim(tasks.get(0).getId(), "tushar", this.getTestUserGroupsAssignments().get("tushar"));
// The task owned method will give the tasks for a user which have been already claimed by him.
tasks = client.getTasksOwned("tushar", "en-UK");
Assert.assertEquals(1, tasks.size());
client.start(tasks.get(0).getId(), "tushar");
Map<String,Object> taskResults = new HashMap<String, Object>();
taskResults.put("insured_name", "Chandra");
client.complete(tasks.get(0).getId(), "tushar", taskResults);
tasks = client.getTasksOwned("tushar", "en-UK");
Assert.assertEquals(1, tasks.size());
ut.commit();
}catch(Exception e){
try {
ut.rollback();
} catch (IllegalStateException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (SecurityException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (SystemException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println("error : " + e.getLocalizedMessage());
}
}
Everything works fine till the code reaches the following line: long processInstanceId = process.getId();
When i try to start the process by firing the following command: WorkflowProcessInstance processInstance = (WorkflowProcessInstance) session.startProcessInstance(processInstanceId);
the code gives me the following error:
>..java.lang.RuntimeException: Could not commit transaction
> at org.jbpm.task.service.TaskServiceSession.doOperationInTransaction>>>>(TaskServiceSession.java:1130)

and after that when i try to lookup for tasks assigned to user "tushar" by firing the following command:
List<TaskSummary> tasks = client.getTasksAssignedAsPotentialOwner(
"tushar", "en-UK", this.getTestUserGroupsAssignments().get("tushar"));
I get 0 task listed.
The task service is induces with the username and group by the help of following function:
private void fillUsersAndGroups(TaskServiceSession taskSession) {
User tushar = new User("tushar");
User venkata = new User("venkata");
User raju = new User("raju");
User ramya = new User("ramya");
taskSession.addUser(tushar);
taskSession.addUser(venkata);
taskSession.addUser(raju);
taskSession.addUser(ramya);
users.put("tushar", tushar);
users.put("venkata", venkata);
users.put("raju", raju);
users.put("ramya", ramya);
Group index = new Group("INDEX");
Group auSme = new Group("TASK 1");
Group uwSme = new Group("TASK 2");
Group accSme = new Group("TASK 3");
taskSession.addGroup(index);
taskSession.addGroup(auSme);
taskSession.addGroup(uwSme);
taskSession.addGroup(accSme);
groups.put("INDEX", index);
groups.put("TASK 1", auSme);
groups.put("TASK 2", uwSme);
groups.put("TASK 3", accSme);
}
and then i assign my self (TUSHAR) in 'INDEX' group by the help of following function:
protected Map<String, List<String>> getTestUserGroupsAssignments() {
Map<String, List<String>> assign = new HashMap<String, List<String>>();
List<String> tusharGroups = new ArrayList<String>();
List<String> venkataGroups = new ArrayList<String>();
List<String> rajuGroups = new ArrayList<String>();
List<String> ramyaGroups = new ArrayList<String>();
tusharGroups.add("INDEX");
venkataGroups.add("TASK 1");
rajuGroups.add("TASK 2");
ramyaGroups.add("TASK 3");
assign.put("tushar", tusharGroups);
assign.put("venkata", venkataGroups);
assign.put("raju", rajuGroups);
assign.put("ramya", ramyaGroups);
return assign;
}
still I gon't get any task assigned .
as far as workflow is concerned, after start, i have an index task whose group id is set as 'INDEX'.
If additional information is needed, do let me know.
I just want to acquire a task and complete it so that it moves to the next node in the workflow.
guys need help seriously :(
Here's my persistance.xml (If that helps):

Solution
just added the following piece of code and it works:
Properties userGroups = new Properties();
userGroups.setProperty("john", "user");
UserGroupCallbackManager manager = UserGroupCallbackManager.getInstance();
manager.setCallback(new DefaultUserGroupCallbackImpl(userGroups));
