Hi Rainer, I'm sorry for the long delay in getting back to you. I got sidetracked by another issue and wasn't able to look into this earlier.
However, the bad news is that the administrators didn't allow me to apply the patch as it is a production server. I can apply it to pre-production, but the error isn't reproducable there... 2nd however; It's been 12 days since we've seen the listenerStart error due to the classDefNotFound (in production). I need to check with the developers whether they accidentily made any changes that might have solved this problem. It might as well be that we have been lucky and that the error starts appearing again tomorrow. I will try to reproduce the problem in another server, in order to try out the patch you supplied. Thanks again. 2009/10/3 Bocalinda <bocali...@gmail.com> > Wow, that's what is called a quick turn around! :) > Thanks.
