Hi Jerome,
I have tried as you suggested, but I am having different issues in different
tests.
I have initialized a static variable in my application with Client object one
time and using it for all my ClientResource calls. Using these changes, if I
now run my test that does a GET of a partcular resource 100 times, this worked
fine. I did not see HTTP Connector start and stop messages I was seeing earlier.
Then I tried a test on another resource that does PUT to create an object. In
this test, it went fine for about 9 calls and then got blocked. It appeared as
if it ran out of connections and blocked. It times out evenutally and gives me
some errors.
Then I tried another test that does a PUT and DELETE on a resource in a loop.
In this situation I see that first PUT and DELETE succeeded, but the next PUT
gets blocked and I eventually get a Null Pointer Exception in the server. I am
exchanging java object representations between client and server.
Can you shed any light on what am I doing wrong here?
Below are my client and server messages:
