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 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989103#...
