RE: Need help: Facing Connection reset: Read timed out: problem w
hen invoking any method on WebdavResource after PUT
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

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.

This is HTTP 1.1. You should be able to reuse the physical
connection. So there is no need to close it explicitly.

As I said the reason might be that Weblogic doesn't properly recognize
the end of the request body and relies on the session being closed.
>

There's the overhead of creating a new connection. Apart from that you
might get in trouble with child resources obtained from this
WebdavResource because you create a new client and the children
continue to use the old client (which now is null).

Fix Weblogic or don't use chunked encoding.
