Hi,
Geronimo: v 2.1.3
OS: Windows XP, Windows Server 2003
I've a web-service that gets polled every N minutes, I noticed that when it
is servicing a request the CPU usage is hitting close to 80%. I expect to
have multiple clients to this web-service so it is going to be a problem.
Based on what I deduced, the following stack trace is trying to load several
of JAR files and not able to load/find them. This is resulting in lot of
kernel level calls thus CPU utilization.

JARs -------------

The following are files this java process is trying to read/load. (Output
from Windows process monitor). It seems to be doing in a loop as I see
continuous system calls to read these jar files repeatedly.

My questions are:
1. I don't see those JARs in the location it is looking for, is there a way
to disable this lookup? Do I've to place those jar files in those locations?
2. Where does class-loader get this list of JARs? Can I tweak anything
there?
3. Did I configure something incorrectly?
Geronimo/Webservice functionally still works, but I'd expect severe problems
when I use this service with multiple ws clients.
Can anyone shed some light on this?
best regards
