Hi there!
I have a problem with the multithreading in cocoon. First I describe what I
want to do and then the problems I have. I want to write a testtool for a
browserbased application with cocoon as frontend. Herefore the tool saves all
requests from client(browser) to the server in a file. After this the tool
should send the requests and interpret the response - whether it is successful
or not. This works fine. Now I want to test the performance of my
application. So I want to run the sending of requests in 2 or more threads.
With 2 threads the test works still fine, but when I run it in more than 2 I
get an exception from the server which I can't interpret. My question: What
does the exception mean and how can I fix it?
BTW: The same exception occurs when I run cocoon on a server with 2 CPUs.
Important details:
VM: Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Applicationserver: JBoss
Webserver: Jetty
