Sorry, this was a "cut-n-pasto":  The contents is from my
    /etc/jserv/jserv.conf   !!
Since Jserv-1.1 there isn't any /etc/apache/jserv.conf.

Hmmm, what's that?  Could Jserv run without Apache?  I do not intend
to run Jserv without Apache.

From my /etc/jserv/jserv.properties file:

# Syntax: log.file=[log path and filename] (String)
# Default: NONE
# Note: if the file could not be opened, try using absolute paths.
log.file=/var/log/jserv.log

The file exists and messages like these

[28/03/2000 10:30:50:493 CEST] ehec: started
[28/03/2000 10:30:50:504 CEST] ehec: started

are filed correctly to it (ehec is the name of one of my servlets).
But the messages I used to write with the System.err.println()
are don't stored in this file and also in no other file.  Those
messages simply vanish :-((((.

/var/log> ls -l jserv.log
-rw-rw-r--    1 www-data www-data        0 Mär 28 20:03 jserv.log

So the file is owned by www-data which should be OK for Jserv and
Apache, isn't it?

I'm really clueless how to track down may debugging and error messages :-(.

Kind regards
