Hi.
I have a jbpm Action handler associated to the event NODE_ENTER of a state. The
first time it executes (when the token enters the node) a timer is created. The
next "n" times (which is fired by the timer and not by the event) the method
tries to look for a Stateful session bean in context. This is the code:
| public class MyActionHandler implements ActionHandler{
|
| private static final long serialVersionUID = -7574831777028763706L;
|
| public void execute(ExecutionContext context) throws Exception{
|
| if(context.getTimer()==null){
| System.out.println("ADDING TIMER ...");
| Calendar cal=Calendar.getInstance();
| BusinessCalendar bc=new BusinessCalendar();
| Duration duration=new Duration("20 seconds");
| Date dueDate=bc.add(cal.getTime(), duration);
|
| Timer myTimer=new Timer();
| myTimer.setName("[TIMER]
"+context.getEventSource().getName());
| myTimer.setDueDate(dueDate);
| myTimer.setRepeat("20 seconds");
| myTimer.setRetries(3);
|
| myTimer.setAction(context.getAction());
|
| context.setTimer(myTimer);
|
|
context.getJbpmContext().getServices().getSchedulerService().createTimer(myTimer);
| }else{
| System.out.println("EXECUTING ...");
| System.out.println("CommonUtil="+Component.getInstance("commonUtil"));
|
| }
| }
|
It fails when it tries to retrieve the SFSB from the context. The log:
| 14:43:25,612 INFO [STDOUT] EXECUTING ...
| 14:43:25,618 WARN [Timer] timer action threw exception

It seems that when the timer if fired it doesn't "look" in the context where
all beans are. Any idea of how can I solve this?. Or a way to inject seam
components within a jbpm timer context? Thanks in advance.
