shane.bryzak Sep 16, 2011 8:46 AM (in response to hrrbrt.h.schumacher.8tsch.net)Can you post the stack trace for the NPE?
In general, don't use 3.1.0.Beta2 - it is an internal only release and a fair bit of stuff is still currently broken. We'll be releasing a Beta3 in the next couple of weeks which will be much more stable.

shane.bryzak Sep 17, 2011 7:54 AM (in response to hrrbrt.h.schumacher.8tsch.net)This exception has nothing to do with logging...

hrrbrt.h.schumacher.8tsch.net Sep 17, 2011 7:58 AM (in response to hrrbrt.h.schumacher.8tsch.net)Thank you!
You might be right, but out-commenting the logging statement in my code makes the Exception disappear an the code execute correctly?! For the time being I have switched back to SLF4J. thanks again! -

shane.bryzak Sep 17, 2011 8:01 AM (in response to hrrbrt.h.schumacher.8tsch.net)What does your logging code look like? I'm assuming that the injection of the Logger is working correctly as you're not getting a Weld exception.

meetoblivion Sep 20, 2011 7:41 PM (in response to hrrbrt.h.schumacher.8tsch.net)Are you trying to inject a logger into your entity? entities aren't managed by CDI, so they are not injectable targets.

ssachtleben.ssachtleben.gmail.com Sep 21, 2011 7:14 AM (in response to hrrbrt.h.schumacher.8tsch.net)Try this:
private final Logger log = Logger.getLogger(MyClass.class);
