After all...I found a possibillity to solve this problem...Here comes a
question for the developers:
The error is thrown in Timerservicebean. First, the EJB Timer becomes cancled
in 'cancelTimersByName'. Afterwards method 'deleteTimersForProcessInstance' is
called and while executing TimerInfo timerInfo = (TimerInfo)
ejbTimer.getInfo(); an error is thrown (in weblogic not in jboss), because
there is no timer object for operation left.
I don't understand this behaviour...so I insert a try...catch block in the
second method and all works fine.
Can somebody explain it to me?
Here are the methods (with my 'correction')
| public void cancelTimersByName(String timerName, Token token) {
| // TODO make the scanning of timers for cancellation optional by only
deleting the timerjobs in the db.
| // of course, the corresponding ejb timer notifications have to be
ignored.
|
| log.debug("cancelling timers with name "+timerName+" from the ejb timer
service");
|
| TimerService timerService = sessionContext.getTimerService();
|
| Iterator iter = timerService.getTimers().iterator();
|
| while (iter.hasNext()) {
| javax.ejb.Timer ejbTimer = (javax.ejb.Timer) iter.next();
| if (ejbTimer.getInfo() instanceof TimerInfo) {
| TimerInfo timerInfo = (TimerInfo) ejbTimer.getInfo();
| if (timerInfo.matchesName(timerName, token)) {
| ejbTimer.cancel();
| }
| }
| }
| }
|
| public void deleteTimersForProcessInstance(ProcessInstance processInstance)
{
|
| // TODO make the scanning of timers for cancellation optional by only
deleting the timerjobs in the db.
| // of course, the corresponding ejb timer notifications have to be ignored.
|
| log.debug("deleting timers for process instance "+processInstance+"
from the ejb timer service");
| TimerService timerService = sessionContext.getTimerService();
| Iterator iter = timerService.getTimers().iterator();
|
| while (iter.hasNext()) {
| javax.ejb.Timer ejbTimer = (javax.ejb.Timer) iter.next();
| try {
| if (ejbTimer.getInfo() instanceof TimerInfo) {
| TimerInfo timerInfo = (TimerInfo) ejbTimer.getInfo();
| if (timerInfo.matchesProcessInstance(processInstance)) {
| ejbTimer.cancel();
| }
| }
| } catch (Exception e) {
| System.out.println("CATCH!");
| }
| }
