Hi,
I am using jboss eap 4.3 and jboss-ws. My application exposes a web service implemented as
a servlet.
I also have a web service client that invokes the web service. So far everything works
okay.
I then started load testing the web service by submitting a number of simultaneously
requests. (I wrote a standalone application to do this). I noticed that most of the times
all the submitted requests are not processed by the web service. For ex. if I run the test
with 25 simultaneous requests, only 22 get processed. The numbers are not consistent and
vary on each run. I also noticed the following errors returned by the web service for some
client requests:
| javax.xml.ws.soap.SOAPFaultException: Read timed out

The following exception is also seen:

I was just wondering if the web service times out under load. If so, is there some way of
increasing the timeout?
Another point worth mentioning here is that the task performed by the web service is time
consuming. So could it be the case that some time consuming web service calls cause a
timeout?
