I'm no expert, so take this as just a try.

You can specify the scope of a web service to be either request, session
or application.
The session scope would help you having the dialog lasting for more than
one request/ reply.

Hi folks.

My supervisor and I are hoping to use SOAP for communications between a 
handheld data collection instrument and the server where the data are 
stored.  For this we need a dialogue between the handheld and the server

that will last for more than one request/response.  If I understand Axis

properly, each request is an island.  How do I persist session data?
suppose I want the server to send two messages for every one sent by the

client.  Or, say I want to fire off an arbitrary number of status
as I process the client's request.  Is there any way (other than writing
separate program and having Axis communicate with it, which seems to
the whole purpose of Axis) to keep a process running that is specific to

one client's session?  Is it possible for the server to send "responses"

without the associated requests?

Does that make any sense?
