[OT]RE: x:transform
Thanks,Kris.I am not sure what the exact problem is yet.I did read the
javadoc.I wish I could use a tool to figure out deadlocks- would something
like JMeter or is there any open source tool to detect memory leaks or
deadlocks ?
Thanks,
Vijay

Subject: RE: x:transform
There are some notes in the Javadoc for DTMManagerDefault:
http://xml.apache.org/xalan-j/apidocs/org/apache/xml/dtm/ref/DTMManagerDefau
lt.html
that suggest the potential for reentrancy issues. I'm not sure if that's
what
you're seeing or not. You might want to try isolating this particular piece
of
your app to run some tests against it. In your original note, you mention
both a
memory leak and deadlock. Which is your real problem?

Re: [OT]RE: x:transform
Posted by Kris Schneider <kr...@dotech.com>.
JMeter won't detect deadlocks or memory leaks, but you could use it to act as
multiple users to simulate the conditions that are triggering your errors. I
haven't used any open source profilers, but you might want to look into a
research tool from Sun called JFluid:
http://research.sun.com/projects/jfluid/
Another tool from Sun that might be of interest is GCspy:
http://www.experimentalstuff.com/Technologies/GCspy/index.html
Of course, you could also give trial versions of OptimizeIt or JProbe a whirl...
