    how create swimlane

      Hello,

      I have created a jbpm portlet. For now I have use this code in order to do working the swimlane assigment:

      package com.opensymphony.webwork.portlet.tutorial;

import java.util.*;


import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.graph.exe.ProcessInstance;
import org.jbpm.db.*;
import org.jbpm.graph.exe.Token;
import org.jbpm.taskmgmt.exe.*;
import org.jbpm.taskmgmt.log.SwimlaneAssignLog;
import org.jbpm.taskmgmt.log.SwimlaneCreateLog;
import org.jbpm.taskmgmt.log.SwimlaneLog;
import org.jbpm.taskmgmt.log.TaskAssignLog;
import org.jbpm.graph.exe.*;
import org.jbpm.graph.log.TokenCreateLog;

import com.opensymphony.xwork.ActionContext;
import com.opensymphony.xwork.ActionSupport;
import org.jbpm.*;

import org.jbpm.taskmgmt.def.*;

import org.jbpm.ant.StartHsqldbTask;
import org.jbpm.context.log.*;

import java.util.Iterator;

public class CreateProcessInstanceAction extends ActionSupport{

 TaskInstance taskinstance=null;
 static JbpmConfiguration jbpmConfiguration = null;
 static ProcessDefinition processDefinition= null;
 Date date;

 JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();
 GraphSession graphSession = jbpmContext.getGraphSession();
 SwimlaneInstance si =null;
 ExecutionContext ec=null;
 private long processus;

 public long getProcessus() {
 return processus;
 }
 public void setProcessus(long processus) {
 System.out.println("set process");
 this.processus = processus;
 }


@Override
public String execute() throws Exception {
 Map session1 = (Map) ActionContext.getContext().get("session");
 String login=(String) session1.get("login");
 System.out.println("mon login:"+login);
 Collection processdefinstances= graphSession.findAllProcessDefinitions();
 Iterator itpro = processdefinstances.iterator();
 while (itpro.hasNext()){
 ProcessDefinition processdef =(ProcessDefinition) itpro.next();
 if(processus == processdef.getId()){
 ProcessInstance processinstance= processdef.createProcessInstance();
 jbpmContext.save(processinstance);
 jbpmContext.loadProcessInstanceForUpdate(processinstance.getId());


 Map swimlanes = processdef.getTaskMgmtDefinition().getSwimlanes();
 Iterator itr = swimlanes.keySet().iterator();
 while(itr.hasNext()) {
 Swimlane swimlane = (Swimlane)swimlanes.get(itr.next());
 swimlane.setPooledActorsExpression(login);
 ec= new ExecutionContext(processinstance.getRootToken());
 SwimlaneInstance swi = processinstance.getTaskMgmtInstance().getInitializedSwimlaneInstance(ec, swimlane);

 /*if(swi.getName().equals("Assurimo")){
 swi.setActorId("bert");
 }*/

 Set pooledActors = swi.getPooledActors();
 if(pooledActors != null) {
 Iterator paItr = pooledActors.iterator();
 while(paItr.hasNext()) {
 ((PooledActor)paItr.next() ).setSwimlaneInstance(swi);
 }
 }

 }

 if (processdef.getTaskMgmtDefinition().getStartTask() != null) {

 org.jbpm.taskmgmt.def.Task task = processdef.getTaskMgmtDefinition().getStartTask();
 String swimlaneName = task.getSwimlane().getName();
 SwimlaneInstance swi = processinstance.getTaskMgmtInstance().getSwimlaneInstance(swimlaneName);
 String originalActorId = swi.getActorId();
 Set originalPooledActors = swi.getPooledActors();
 System.out.println("taskinstance");
 TaskInstance startTask = processinstance.getTaskMgmtInstance().createStartTaskInstance();
 startTask.setActorId(login);
 startTask.setDueDate(date);

 if(startTask.getSwimlaneInstance() != null) {
 si = startTask.getSwimlaneInstance();
 startTask.getSwimlaneInstance().setActorId(login);

 if (startTask.getSwimlaneInstance().getPooledActors() != null) {

 }
 }

 }
 else {
 }

 jbpmContext.save(processinstance);
 jbpmContext.close();
 }
 }

 return SUCCESS;
 }
}


      Now I want create automatically my swimlane for processes, but how create a swimlane from the process definition.

      thank you for your help

          hello,

          when I create a porcess, I don't know why jbpm want that I define all the user of the swimlanes. How can create my swimlanes without run my all process.

          because I create a start task without swimlane and after I have a swimlane task in my case. So when I instanciate my process I have this error:

          JBPM want a definition of ernie but I'm not in this node yet for executing I just create my start node. can you help me ?

          I want create a java file which permit me to create all the possible processes like the webapplication of the quickstart, (in a portlet). for the moment I can create a porcess if my start task in assign by swimlane to a specific person. So I want to generalize file to create any processes that I want to.

          thank you for your help
