Hi,
I have one output on my human task, the output is of type String, and I map this output to one of the process variable.
The problem is, the mapped value becomes:
MarshalledContentWrapper{content=[B@342371e7, marshaller=org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy, type=class java.lang.String}
how to make it resolve correctly to the String value?
here is my code
1. Map<String, Object> taskOutput = new HashMap<String, String>(1);
2. taskOutput.put("EvaluationResult",
3. "good");
4.
5. ContentData contentData = new ContentData();
6. contentData = ContentMarshallerHelper.marshal(taskOutput,
7. new ContentMarshallerContext(), null);
8.
9. taskClientHelper.completeTask(taskId.longValue(),
10. userId, contentData);
Any help is appreciated.
Best Regards,
Thomas Setiabudi

I need to get the tasks by status and then start them.
But at some times while retrieveing the tasks im getting the started process id as well and thats in where im getting this exception.
org.jbpm.task.service.PermissionDeniedException: Server-side Exception: User '[User:'admin']' was unable to execution operation 'Start' on task id 287271 due to a no 'current status' match

My mina task handler is running in jboss and the application uses its client to the task operations.
Retrieveing tasks by status:
BlockingTaskSummaryResponseHandler resHandler = new BlockingTaskSummaryResponseHandler();
List<Status>statusls=new ArrayList<Status>();
statusls.add(Status.Reserved);
client.getTasksAssignedAsPotentialOwnerByStatus("admin",statusls, "en-UK", resHandler);
Starting the task:
BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
client.start(taskId, userId, responseHandler);
*Is there any thing to do with hibernate or what should i take care to eliminate this replication.?*

you need to add the user to takservice by using the following code
|
|
|
| Properties userGroups = new Properties(); |
|
|
|
| userGroups.setProperty("john", "user"); |
|
|
|
| UserGroupCallbackManager manager = UserGroupCallbackManager.getInstance(); |
|
|
|
| manager.setCallback(new DefaultUserGroupCallbackImpl(userGroups)); |
*or* implement a an UserGroupCallback. Then
UserGroupCallbackManager manager = UserGroupCallbackManager
.getInstance();
if (!manager.existsCallback()) {
UserGroupCallback userGroupCallback = new JBPMUserGroupCallback();
manager.setCallback(userGroupCallback);
}
this is the callback implementation:
public class JBPMUserGroupCallback implements UserGroupCallback {
@Override
public boolean existsGroup(String groupId) {
return true;
}
@Override
public boolean existsUser(String userId) {
return true;
}
@Override
public List<String> getGroupsForUser(String userId, List<String> groupIds,
List<String> allExistingGroupIds) {
if(groupIds != null) {
List<String> retList = new ArrayList<String>(groupIds);
// merge all groups
if(allExistingGroupIds != null) {
for(String grp : allExistingGroupIds) {
if(!retList.contains(grp)) {
retList.add(grp);
}
}
}
return retList;
} else {
//
// return empty list by default
//please note: there are different return value for different version of jPBM
//List<String> retList = new ArrayList<String>();
//retList.add("user");
//return retList;
//return new ArrayList<String>(); //for jBPM5.3.0.Final
return null; //for jBPM5.4.0.CR1
}
}
}
