Hi Koen, thank you for the response, i've already read the docs but what i want
to do is:
order-> task node (accept/cancel order)-> end
it's quite simple, if in a fixed period i don't accept or cancel explicity the
order, it will be automatically executed and the system ends. I tried to make
it in jbpm but when the timer starts, in the java:
package org.jbpm.example;
|
| import org.apache.commons.logging.Log;
| import org.apache.commons.logging.LogFactory;
| import org.jbpm.context.exe.ContextInstance;
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
| import org.jbpm.taskmgmt.def.Swimlane;
| import org.jbpm.taskmgmt.def.TaskMgmtDefinition;
| import org.jbpm.taskmgmt.exe.SwimlaneInstance;
| import org.jbpm.taskmgmt.exe.TaskMgmtInstance;
|
| public class timeOut implements ActionHandler {
|
| private static final long serialVersionUID = 1L;
|
| String swimlaneName;
| String msg;
|
| public void execute(ExecutionContext executionContext) throws Exception {
| TaskMgmtDefinition taskMgmtDefinition =
executionContext.getProcessDefinition().getTaskMgmtDefinition();
| TaskMgmtInstance taskMgmtInstance =
executionContext.getTaskMgmtInstance();
| ContextInstance contextInstance = executionContext.getContextInstance();
|
| Swimlane shipperSwimlane = taskMgmtDefinition.getSwimlane("user");
| SwimlaneInstance shipperSwimlaneInstance =
taskMgmtInstance.getInitializedSwimlaneInstance(executionContext,
shipperSwimlane);
|
| String actorId = shipperSwimlaneInstance.getActorId();
|
| String displayMsg = "a";//replace(msg, "${"+swimlaneName+"}", actorId);
| //displayMsg = replace(displayMsg, "${item}",
(String)contextInstance.getVariable("item"));
| //displayMsg = replace(displayMsg, "${date}",
(String)contextInstance.getVariable("date"));
|
| log.info("###############################################");
| log.info("### TimeOut: "+displayMsg);
| log.info("###############################################");
|
| executionContext.leaveNode();
| }
|
| static String replace(String msg, String pattern, String replacement) {
| String replaced = null;
| int pos = msg.indexOf(pattern);
| if (pos!=-1) {
| replaced = msg.substring(0,pos)
| +replacement
| +msg.substring(pos+pattern.length());
| }
| return replaced;
| }
|
| private static final Log log = LogFactory.getLog(timeOut.class);
| }
it leaves the node but informs of an error:

the cause seems to be:
Caused by: org.jbpm.JbpmException: can't leave node 'Node(auto-out)'
without leaving transition
i don't understand it... should be this done in a differente way? any help will
be very appreciated...
