Subject Re: Null Pointer exception with camel quartz simple trigger (fireNow)
Date Thu, 29 May 2014 08:17:20 GMT
Hi

Sounds like you have an exception being thrown during routing, and the
quartz component just logs that.

So either use an error handler to handle that exception. Or do not use
fireNow, but use a delay so quartz does not fire asap, but give a bit
of time for the other resources to be ready.
