The abovementioned code is executed approx. 10 times a second from the beggining and never fails except when downing tomcat...
I also see the log entries in the log file, so the logging works during the lifetime of the application. Forgot to mention, but all of the NPEs happen in threads. The timer is a daemon thread, the queuedeventsender a non-daemon thread. > It's also possible that the NPE is coming from somewhere deeper in the > log.error() call, and just being propagated back to your code. Yes, I had one further exception where it happened in jdk code itself (somewhere in a buffer), still, if the stacktraces don't lie I got one npe in if (log.isDebugEnabled()) and I think it can only happen if log is null? regards Leon On 4/26/06, Caldarale, Charles R <[EMAIL PROTECTED]> wrote: > > From: Leon Rosenberg [mailto:[EMAIL PROTECTED] > > Subject: tomcat 5.5.16 does strange things with my log4j? > > > > I get null pointer exceptions in following code: > > static{ > > log = Logger.getLogger(QueuedEventSender.class); > > } > > static { > > log = Logger.getLogger(TimerServiceImpl.class); > > } > > As part of the debugging effort, how about checking for null return > values from getLogger() in the static initializer?
