Do you want to *always* trace the errors logged in Eclipse's log file or
just in some scenarios? One way you can do this is by using Probekit in
TPTP, which allows you to do static/dynamic byte code instrumentation.
Please see "Probing Java application behavior with Probekit" in here
http://www.eclipse.org/tptp/home/documents/conferences/eclip seCon2006/index.html
and check out the Demo.zip file posted. Also see the help content of TPTP
for more information.
With Probekit, you can write probes that target the class which logs error
messages in Eclipse. You can then take the error message and retarget it
to your logging file. The Demo.zip file contains a couple of sample
probes, see the readme file included in this zip file for more info. I'm
also attaching a simple probe that logs messages to a file for each method
entry/exit and any exceptions that occur.
Now the question is whether you want to always monitor Eclipse's error
messages or just in some scenarios. If it's just in some scenarios you
can easily do this using dyanmic probekit. If you want to always capture
these error messages, you can statically instrument the JAR file that
contains the class respsonsible for logging to Eclipse's log file and use
the modified JAR file to always capture Eclipse's error messages.

Hi Paul,
Registering my custom LogListener with the platform's logger is exactly
what I wanted to achieve. I previously tried registering to various
platform plugin loggers, but your solution is the one I was looking for.
Thanks!
Regards,
Robert
