Not getting latest Process definition

chprvkmr Nov 30, 2005 11:27 AM

Hi All,

I have created a par file that contains processdefinition.xml(say with name pdefTest1.xml), processimage.jsp and gpd.xml. I deployed it and able to create process instances on it. But when I updated processdefinition.xml (pdefTest1.xml) and redeployed that par file, it got loaded successfully in database but its not there in the list fetched by graphSession.findLatestProcessDefinitions() [getting old processdefinition id only] . Whenever I modified processdefinition, I need to give it a new name in <process-definition name="<new name>"> tag so as to obtain it from graphSession.findLatestProcessDefinitions(). Is there any workaround for this

Thanks in advance

Hi Kukeltje,

My par file contains below contents::

gpd.xml
processdefinition.xml
processimage.xml

I have created a new process project using eclipse plugin, which created by default sample.par folder with above contents. Later I modified the processdefinition.xml file, adjusted the image [ as boxes are overlapped], checked whether processimage.jsp reflects my processdefinition or not. If everyting is fine then compressed sample.par folder and renamed it to testPdef1.par.

Iam loading this par file through a jsp page

<%@ page language="java" %>
<%@ page import="org.jbpm.graph.def.*,org.jbpm.graph.exe.*,org.jbpm.taskmgmt.exe.*,com.sample.workflow.bean.*,java.util.*,org.jbpm.db.*,com.sample.workflow.context.*,java.io.*" %>

<%
 UserBean objUserBean = (UserBean) session.getAttribute("userBean");
 if(objUserBean == null)
 {
%>
 <jsp:forward page="demo1Login.jsp"/>
 <%
 }

 String processDefPARPath = request.getParameter("xmlPathProcessDef");
 if(processDefPARPath == null || processDefPARPath.trim().equals(""))
 {
 %>

 <center>Please select process definition path to continue .....
 <p><a href="demo1Home.jsp">Home</a></center>
<%
 return;
 }
%>

<%
 // Get process definition
 ProcessDefinition processDefinition = null;
 try
 {
 processDefinition = ProcessDefinition.parseParResource(processDefPARPath);
 }
 catch(Exception fne)
 {
%>
 <p><font color='red'>Error:: <%= fne.getMessage() %></font>
 <p><center>Failed to start process.
 <p><a href="demo1Home.jsp">Home</a></center>
<%
 fne.printStackTrace();
 return;
 }

 // Save process definition in db.
 JbpmSession jbpmSession = Context.getPersistenceContext().getJbpmSession();

 GraphSession graphSession = jbpmSession.getGraphSession();

 graphSession.saveProcessDefinition(processDefinition);
%>

 <center>Started process with Id, <b><%= processDefinition.getId() %></b> successfully
 <p><a href="demo1Home.jsp">Home</a></center>

This way Iam able to store par file in database. Later I can get the processdefinitions with graphSession.getLatestProcessDefinitions() method.

If I try to deploy another/modified processdefinition with the same name as that of already existing process definition[old one], its getting loaded successfuly. But while fetching process definition list[graphSession.getLatestProcessDefinitions()], instead of modified process definition, old process definition is fetched.

Anyone can listout the situations where graphSession.findLatestProcessDefinitions() fails to fetch latest definitions. For a particular processdefinition Iam getting old version being listed instead of latest one.
