Hi
Our goal of a service layer is to have a service description which is
platform- and language dependent. Therefore, the platform specific things
must be wrapped otherwise you won't have a well-designed web service and
are never able to reuse or migrate the web service implementation to
another platform without an impact on the client side.
Why don't you define a single operation called:
String runProg (String args)
The implementation of this operation will then call the three methods on
the legacy system in the desired order.
Regards
Oliver

Thema: Web Service with state

Hi!
I'm building a web service that need a internal state. This is needed
because the web service will start a legacy program that takes input from a
prompt. This is my calls:
int threadId : runProg( String args )
void sendInput( threadId, String args)
String getResult( threadId)
Have read that web service has to be state-less. Why is that?
Unfortunately I have no choice here because I cant rewrite the legacy
application.
Thanks in advance
/Kalle
