Subject RE: FAQ? shutdown.bat not killing java process on Windows
Date Mon, 03 Oct 2005 20:26:09 GMT
Why bother IBM. In my startup script, I clean up any java process:

for i in `ps ax --format ppid,pid,cmd |grep java |egrep
"^[[:space:]]*1[[:space:]]" |tr -s ' ' |cut -f3 -d" "`
do
    echo "killing $i..."
    kill -9 $i
done

Heh, I'll call IBM and have them do just that. ;-)

It happens in their JT400 classes.
