I have an application which is using Seam and Jboss 4.0.5. I have a timer
(setup through seam, don't ask me how), which every 20 seconds checks an imap
account, loads any new e-mail in, and then processes them.
| @Asynchronous
| @Transactional
| public void processEmailsRecurring(@Expiration
| Date pDate, @IntervalDuration
| long pInterval) {
| mLog.info("proccessEmailsReccurring running...");
| this.mEmailManager.processNewEmails(mIMAPClient.getNewMessages());
| }
|
This works perfectly for days or hours. Then it starts dying. The
mIMAPClient.getNewMessages() gets called, but before the processNewEmails is
called, this error shows up in the logs:
| ERROR [org.jboss.ejb.txtimer.TimerImpl] Error invoking ejbTimeout:
javax.ejb.EJBException: java.lang.NullPointerException
|
It then does that (getNewMessages(), ERROR, end) every 20 seconds. Once I
notice that the site has died, I can go in and flush out the mail spool, and
that seems to "fix" it for a time.
What could be causing the ERROR [org.jboss.ejb.txtimer.TimerImpl] Error
invoking ejbTimeout: javax.ejb.EJBException: java.lang.NullPointerException?
I've tried to back track through the jboss source, but there is so many layers
and injection and such, that I have no idea where it is coming from, or why it
only happens sometimes, or how I can fix it.
Any ideas or info would be greatly appreciated.
Thank you!
Modoc
