Thanks a lot for the quick reply Ingo.
After sending out my first mail I did a small test: I explicitly closed the
HttpConnection at the end of the Put Method.
More specifically: I added the following lines at the end of the putMethod
of WebdavResource:
closeSession();
client = getSessionInstance(httpURL);
And yeah this fixed the problem.
I don't have much experience with HttpUtil. I have a couple of questions:
1. What should be the expected behavior? Should the session have been closed
by default or is it something the program has to do explicitly?
2. Why does this problem surface only in case of Weblogic and not JBoss?
3. Will the above fix cause any other issues?
4. Is there any other better fix for this issue?
Thanks again,
Ritu

Subject: Re: Need help: Facing Connection reset: Read timed out: problem
when invoking any method on WebdavResource after PUT
The first thing that comes to my mind is that Weblogic might not be able to
handle the chunked transfer encoding correctly that is used when your
upload source is a stream. It looks like it cannot detect the end of
the request body.
I would rather expect this to be a Weblogic problem than a bug in
Httpclient since the latter doesn't give any problems with other
servers.
