Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Components: client-api
Environment: java 1.5, windows sp2 (and mac os 10.4.7)
Reporter: Michele Mazzucco
After running a stateful web service for some time (~ 4 hours and 3000
requests) I got some exceptions like this:
Unable to send the response to
[http://10.8.150.50:6060/axis2/services/annonService16226000/annonOutInOp]:
org.apache.axis2.AxisFault: Two services can not have same name, a service with
annonService29404790 already exists in the system

I think here there are 2 problems:
1 - the client generated the same random value (annonService16226000): the used
service client is always the same
2 - the service does not delete this "service" (which is actually used *only*
to send an asynchronous result).
I guess the problem 1 could be resolved using a counter of type long (say
initialized with the current timestamp), that is at the first invocation you
get annonService<init_timestamp>, second invocation (I'm assuming the same
ServiceClient is used) is annonService<init_timestamp + 1>, ecc.
