Hi,
Can anyone recommend an dynamic instrumentation tool for Java?
I am interested in a solution that would work also on the server side (in particular,
inside a JBoss server).
I found some links, but I do not know how good they are:
http://java-source.net/open-source/profilers
Cheers,
Doru

As far as I know, Javassist is what you need. I have used it for byte
code instrumentation and is relatively easy to learn and use, if I
remember correctly JBoss provides support for it. Take a look to:
http://www.jboss.org/javassist

AspectJ also does a pretty good job. But all in all, it depends what you want to extract
from the execution. Which kind of metric or data are you interested in ?
We are currently writing an agent for the JVM to extract low level data.
Cheers,
Alexandre

Hi,
I am interested in the exact traces including distinguishing between
different clients and different threads.
Cheers,

AspectJ sounds like what you need, but I am not familiar in that area.

As Alex mentioned, one option would be to roll your own using AspectJ. If you just need a
log to a file with all called methods, recieviers, arguments and the executing thread,
this should be quite trivial. I guesstimate that 50 LOC should be an upper bound.
