Whe in do Persona persona = (Persona)$processInstance.getVariable("personaVar");
persona is null.
I would like to know what I am missing??
Thanks in advance for your help.

In "Solicitud Empleado", are you giving any value to "persona"? You
have configured the output of that Human Task to return a "persona" and to set
the value of "personaVal" with its value. So, if you are not providing any
"persona" when you are completing the task, "null" is going to be
assigned to that variable.

Thanks, for your answer.
I run this code to start task:
public String iniciarTareaSolicitudEmpleado( ){
HumanTaskClientMina htk = new HumanTaskClientMina();
User u= new User("operator");
List<TaskSummary> t = htk.getAssignedTasks( u );
System.out.println( "Tarea " + t.get( 0 ).getId() );
htk.startTask( u , t.get( 0 ));
return null;
}
public void startTask(User user, TaskSummary task) {
BlockingTaskOperationResponseHandler operationResponseHandler = new
BlockingTaskOperationResponseHandler();
client.start( task.getId(), user.getId(), operationResponseHandler);
operationResponseHandler.waitTillDone(DEFAULT_WAIT_TIME);
}
I run this code to complete task:
public String termiTareaSolicitudEmpleado( ){
HumanTaskClientMina htk = new HumanTaskClientMina();
User u= new User("operator");
List<TaskSummary> t = htk.getAssignedTasks( u );
htk.completeTask(u, t.get( 0 ), null);
return null;
}
public String termiTareaOperator( ){
HumanTaskClientMina htk = new HumanTaskClientMina();
User u= new User("operator");
List<TaskSummary> t = htk.getAssignedTasks( u );
Map<String, Object> m = new HashMap<String, Object>();
m.put( "persona" , new Persona( "1713", "OSO
T" ));
htk.completeTask(u, t.get( 0 ), null);
return null;
}
public void completeTask(User user, TaskSummary task, Map data) {
BlockingTaskOperationResponseHandler operationResponseHandler = new
BlockingTaskOperationResponseHandler();
ContentData contentData = null;
if (data != null) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out;
try {
out = new ObjectOutputStream(bos);
out.writeObject(data);
out.close();
contentData = new ContentData();
contentData.setContent(bos.toByteArray());
contentData.setAccessType(AccessType.Inline);
}
catch (IOException e) {
System.err.print(e);
}
}
client.complete(task.getId(), user.getId(), contentData,
operationResponseHandler);
operationResponseHandler.waitTillDone(DEFAULT_WAIT_TIME);
}
Where should i set persona values??
Thanks in advance.

If you are not planning to modify "persona" in the User Task, then is should be
enough to remove it from the Result Mapping attribute of "Solicitud Empleado".
But, if the User Tasks modifies "persona" in any way, you need to pass it in the
Map recevied by:
+public void completeTask(User user, TaskSummary task, Map *data*)+
I think, that in your case, you need to pass variable 'm' to the completeTask()
method. As far as I can see, you are declaring the Map, setting "persona" in it,
but then you are not passing it (as the third parameter) to the completeTask() method.

I don't trust in the editor. This problems are usually related with a typo or with
some forgotten mapping. If you cannot solve it please share the bpmn/xml file that
describe the process, so we can check the mappings.
Cheers

Do you have com.lincoln.jbpm.model.Persona in the application classpath?
Are you using jbpm-gwt-console? Where are you getting this error? client application, jbpm
runtime or human task server?

Hi,
Persona is in the classpath, it is deployed a as WAR next to bpmn and drl files.
I am using Human Task Server, and running the flow through web interface.

I have fixed this problem, I have to generate a Jar file whith Persona class.
I have another issue now, I have this flow:
start->Human Task1 -> Rule Task -> Huma Task2 -> Email Task -> Human
Task3-> end
When i complete human Task 2 trigger Email Task, but Service Task do not get finished,
that is the reason why Human Task3 never start.
If I use another flow like:
start->Human Task1 -> Rule Task1 -> Huma Task2 -> Rule Task2 -> Human
Task3-> end
It works fine, I would like to know why Email Task does not get ended.
Thanks in advance

EmailWorkItemHandler code is:
import org.drools.runtime.process.WorkItem;
import org.drools.runtime.process.WorkItemHandler;
import org.drools.runtime.process.WorkItemManager;
public class EmailWorkItemHandler implements WorkItemHandler {
public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
// extract parameters
try {
System.out.println("================================>> ingresa a
executeWorkItem EmailWorkItemHandler");
String from = (String)
workItem.getParameter("From");
System.out.println("================================>> From
" + from );
String to = (String) workItem.getParameter("To");
//String message = (String)
workItem.getParameter("Message");
manager.completeWorkItem(workItem.getId(),null);
} catch (Exception e) {
e.printStackTrace();
}
}
}

are you binding the "
|
| | MiNotificacion |
|
|
To the tns:name attribute in your <task> ??
Are you getting those system.outs in your console or an stack trace?
The work item should be completed and the process should continue with the information
that you are sharing with us.
Cheers

Luis,
The workitems handlers are mapped to "task types" and not task names. If you are
using the custom Email node which comes with the pallete, you should register it with
"Email". Otherwise, you will have to register with "tns:taskName"
value which you can find it if you open the bpmn as xml.
Usually, these are custom nodes and you define the "type" in the .conf with your
nodes, and there you will find the name of the node type (

Yeah.. Demian nail it:
you should change this line to make it work
ksession.getWorkItemManager().registerWorkItemHandler("Email", new
EmailWorkItemHandler());
To match with your process definition
<task id="_7" name="envio email" tns:taskName="Email"
>
Cheers

Thanks, I change to
ksession.getWorkItemManager().registerWorkItemHandler("Notification", new
EmailWorkItemHandler()); and then works.
Now I am facing another problem, I need to get information of Person in HumanTask 2, I am
using this code:
public Object getTaskContentInput(TaskSummary taskSum) {
System.out.println( "======>Entra a ver
getTaskContentInput" );
try {
BlockingGetTaskResponseHandler handlerT = new
BlockingGetTaskResponseHandler();
client.getTask(taskSum.getId(), handlerT);
Task task2 = handlerT.getTask();
TaskData taskData = task2.getTaskData();
BlockingGetContentResponseHandler handlerC = new
BlockingGetContentResponseHandler();
client.getContent(taskData.getDocumentContentId(),
handlerC);
Content content = handlerC.getContent();
ByteArrayInputStream bais = new ByteArrayInputStream(
content.getContent());
ObjectInputStream is = new ObjectInputStream(bais);
Object obj = null;
while ( (obj = is.readObject()) != null ) {
return obj;
}
} catch (Exception e) {
System.err.print("There was an error reading task
input...");
e.printStackTrace();
}
return null;
}
public String imprimirTareasConsola( ){
HumanTaskClientMina htk = new HumanTaskClientMina();
User u= new User("operator");
System.out.println( "======>Operador" );
List<TaskSummary> t = htk.getAssignedTasks( u );
if( t!= null && t.size() >0 ){
Object xx= htk.getTaskContentInput(t.get( 0 ));
if( xx != null ){
System.out.println( "===> Class name en
content: " + xx.getClass().getName());
if( xx instanceof Persona ){
System.out.println( "==00> Id en
content type " + ((Persona)xx).getId() );
} else if( xx instanceof String ){
System.out.println( "==00> name
type " + (String)xx);
}
System.out.println( "===> cerrando Class
name en content: " );
} else {
System.out.println( "==> El content es
null " );
}
}
return null;
}
Always the object returned is String, do you have any ideas how can I get the object
modified in previus task.
