Logging of compile / runtime error messages

Hello,

if there occurs any compile or runtime problem in a jsp-file I get only a Http500-error page, no further hints as to where exactly the problem occured, exception stack trace, javac output etc.

I knew from WAS 6.20 that these messages could be found in the general log file.

Now, I have already set quite a few of the standard logging categories and locations to debug level, but still no output. Where can I switch on this debug output information ?

It's really hard working without any detailed error messages. I tried this both in release 6.30 and 6.40.

Your help would be - as always - appreciated.
