My workflow doesn't run correctly
Can anybody test my example, and see if, if my worflows runs correctly? In my pc, the workflows doesn't pass from the first task-node to the second.
Here is the code:
package com.sample.jbpm;
import org.jbpm.graph.def.*;
import org.jbpm.graph.exe.*;
import org.jbpm.taskmgmt.exe.*;
import com.sample.debug.MyDebug;
//import org.jbpm.taskmgmt.def.*;
import java.util.Vector;
import java.util.Iterator;
public class WorkFlow implements ActionHandler
{
private Vector formParameter;
public ProcessDefinition processDefinition;
public ProcessInstance processInstance;
public Token token;
public TaskInstance taskInstance;
public Iterator it;
public WorkFlow()
{
processDefinition = ProcessDefinition.parseXmlString(
"<process-definition name='simple'> " +
" <start-state name='start'> " +
" <transition name='to_registo_ocorrencia' to='registo_ocorrencia'/> " +
" </start-state> " +
" <task-node name='registo_ocorrencia'> " +
" <task name='RegistoOcorrenciaTask'/> " +
" <transition name='to_lista_tarefas' to='lista_tarefas'> " +
" </transition> " +
" </task-node> " +
" <task-node name='lista_tarefas'> " +
" <task name='ListaTarefasTask'/> " +
" <transition name='to_notificacoes' to='notificacoes'/> " +
" </task-node> " +
" <task-node name='notificacoes'> " +
" <task name='NotificacoesTask'/> " +
" <transition name='to_end' to='end'/> " +
" </task-node> " +
" <end-state name='end'/> " +
"</process-definition> "
);
/* ProcessInstance is one execution of a ProcessDefinition */
processInstance = new ProcessInstance(processDefinition);
/* represents one path of execution */
token = processInstance.getRootToken();
token.signal();
}
public void RegistoOcorrenciaTask()
{
/* taskInstance is one task instance that can be assigned to an actor */
taskInstance = (TaskInstance) processInstance.getTaskMgmtInstance().getTaskInstances().iterator().next();
/**
* RegistoOcorrenciaTask
**/
if(taskInstance.getName().equals("RegistoOcorrenciaTask"))
{
// Já tenho que ter os parâmetros inicializados
//formParameter = (Vector) taskInstance.getTaskFormParameters();
MyDebug.print("xxxxxxxxxx RegistoOcorrenciaTask xxxxxxxxxxx");
MyDebug.print("getName()\t--> " +taskInstance.getName());
MyDebug.print("isSignalling()\t--> " +taskInstance.isSignalling());
MyDebug.print("isBlocking()\t--> " +taskInstance.isBlocking());
//Daqui posso chamar outras funções java para tratar os argumentos.
taskInstance.end();
MyDebug.print("hasEnded()\t--> " +taskInstance.hasEnded());
MyDebug.print("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
}
}
public void ListaTarefasTask()
{
taskInstance = (TaskInstance) processInstance.getTaskMgmtInstance().getTaskInstances().iterator().next();
System.out.println("TASKINSTANCE " + taskInstance.getName());
/**
* ListaTarefasTask
*/
if(taskInstance.getName().equals("ListaTarefasTask"))
{
//taskInstance.setActorId("User");
MyDebug.print("############# ListaTarefasTask ###########");
MyDebug.print("getName()\t--> " +taskInstance.getName());
MyDebug.print("isSignalling()\t--> " +taskInstance.isSignalling());
MyDebug.print("isBlocking()\t--> " +taskInstance.isBlocking());
taskInstance.end();
MyDebug.print("hasEnded()\t--> " +taskInstance.hasEnded());
}
}
public void NotificacoesTask()
{
taskInstance = (TaskInstance) processInstance.getTaskMgmtInstance().getTaskInstances().iterator().next();
/**
* NotificacoesTask
*/
if(taskInstance.getName().equals("NotificacoesTask"))
{
MyDebug.print("############# NotificacoesTask ###########");
MyDebug.print("getName()\t--> " +taskInstance.getName());
MyDebug.print("isSignalling()\t--> " +taskInstance.isSignalling());
MyDebug.print("isBlocking()\t--> " +taskInstance.isBlocking());
taskInstance.end();
MyDebug.print("hasEnded()\t--> " +taskInstance.hasEnded());
}
}
public ProcessDefinition getProcessDefinition()
{
return processDefinition;
}
public ProcessInstance getProcessInstance()
{
return processInstance;
}
public Token getToken()
{
return token;
}
public TaskInstance getTaskInstance()
{
return taskInstance;
}
/**
* Retorna um vector com todos os parametros
* indicados no registo de ocorrencia
* @return Vector
*/
public Vector getFormParameter()
{
return formParameter;
}
public static void main(String[] args){
WorkFlow wf = new WorkFlow();
wf.RegistoOcorrenciaTask();
wf.ListaTarefasTask();
wf.NotificacoesTask();
}
public void execute(ExecutionContext executionContext) throws Exception {
MyDebug.print("------> ENTROU NO EXECUTE <---------");
executionContext.leaveNode();
}
}
The output is:
xxxxxxxxxx RegistoOcorrenciaTask xxxxxxxxxxx getName() --> RegistoOcorrenciaTask isSignalling() --> true isBlocking() --> false hasEnded() --> true xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx TASKINSTANCE RegistoOcorrenciaTask log4j:WARN No appenders could be found for logger (org.jbpm.jpdl.xml.JpdlXmlReader). log4j:WARN Please initialize the log4j system properly.
Can anybody understand why this happens?
Please, I'm desperate.
Thanks.
