Hello.
I'm trying to ceate a simple console application with jbpm and timers. What I did is
quite simple:
public static void main(String[] args)
| {
| try
| {
| JbpmConfiguration conf =
JbpmConfiguration.getInstance("src/main/config/jbpm.cfg.xml");
| JbpmContext ctx = conf.createJbpmContext();
| ZipInputStream zis = new ZipInputStream(new
FileInputStream("/test1.par"));
| ProcessDefinition pDef = ProcessDefinition.parseParZipInputStream(zis);
| ctx.deployProcessDefinition(pDef);
| zis.close();
| conf.startJobExecutor();
|
| ProcessInstance pInst = ctx.newProcessInstance("test1");
| pInst.signal();
| }
| catch (Exception ex)
| {
| ex.printStackTrace();
| } and the process definition goes as follows:<process-definition
| xmlns="urn:jbpm.org:jpdl-3.2" name="test1">
| <start-state name="start-state1">
| <transition to="state1"
name="to_state1"></transition>
| </start-state>
| <state name="state1">
| <timer duedate="2 seconds" name="timy_timer"
repeat="yes">
| <action class="TimerActionHandler"></action>
| </timer>
| <transition to="state1"
name="to_state1"></transition>
| </state>
| </process-definition>. The problem is, I'm unable to execute the handler.
I've tried to find some answer for that in the posts, but one I've found, I guess,
referred to the 3.1.x and if I got it right, the timers have been seriously refactored
since that time. What I've discovered is that the jbpm-console does it right, I mean
it somehow adds a new record to the jbpm_job table in the database. What i did, was a
simple experiment: started JBoss, configured and deployed the console, deployed the same
process and run it. Then killed JBoss with entries left int the database (I use
PostgreSQL). My code is able now to run the orphaned timers, yet it is unable to create
the new ones. What else should I do to make it happen ? My jbpm.cfg.xml is like this:

| </bean>
| </jbpm-configuration> and Hibernate is set to use PostgreSQL, of course.
I get no exceptions. The handler is simply not invoked (or invoked only when it is
deployed through the jbpm-console). Thanks in advance for help.
