<div class="jive-rendered-content"><p>Hello,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I have a confusion between the processInstance and the Task with Jbpm5. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My scenario is as explain bellow :</p><p><a href="https://community.jboss.org/servlet/JiveServlet/showImage/2-775721-19863/N_PL.png"><span> https://community.jboss.org/servlet/JiveServlet/downloadImage/2-775721-19863/195-279/N_PL.png </span></a></p><p>1/ A user enters in the application and starts a new processInstance of a jbpm process.</p><pre class="jive-pre"><code class="jive-code jive-java">                                ProcessInstance process = ksession.startProcess(<font color="red">"com.st.ams.flow.npl"</font>, params);
                                System.out.println(<font color="red">"process = "</font>+process.getProcessId()+<font color="red">" : "</font>+process.getProcessName()+<font color="red">" : state("</font>+process.getState()+<font color="red">")"</font>);
</code></pre><p>2/ A new task is created in the database in the state Ready with the name "startNPLRequest_PM_PL", and with this code I am abble to see that my user can claim this task and complete it :</p><pre class="jive-pre"><code class="jive-code jive-java">                                <font color="darkgreen">//Now the PM_PL process his task (it is already complete in reality)</font>

                              <font color="navy"><b>for</b></font>(String grp : groups)<font color="navy">{</font>
                                        System.out.println(<font color="red">" - "</font>+grp);

                              <font color="navy">}</font>
 
</code></pre><p>3/ The problem is that several users with the role PM_PL will launch this process at the same time, so how can I assign the good task (of the good process but I know the processId) to my user?</p><p>     I have not find the link between processId and taskId. And I need the taskId to start the task :</p><pre class="jive-pre"><code class="jive-code jive-java">                    amsKnowledgeSession.getClient().start( taskId, requestorId, taskSummaryResponseHandler );
