Thank you Hiranya.
As I delineated before, I have a client which can be used to invoke my
service remotely.
With my client I can use one of these three stubs obtaining the same correct
result:
// It refers to the service deployed in Axis2 in TomCat
stub = new SumCalculatorStub("*
http://localhost:8080/axis2/services/SumCalculator*";);
// It refers to the service deployed in Axis2 within Synapse
stub = new SumCalculatorStub("*http://localhost:9000/soap/SumCalculator*";);
// It refers to the service visible through transport URL of Synapse
stub = new SumCalculatorStub("*http://localhost:8280/soap/SumCalculator*";);
Now:
*1)* how can I try some modifications to it, so that instead of directly
invoking the
Axis2 service, it sends the request to Synapse?
Is there a relation with the transport URL of Synapse http://localhost:8280?
*2)* if I resolve the question 1) what will I see in the Synapse prompt?
The SOAP request-response, or a simple notification of the flow?
*3)* running the sample 150 I saw a reference at some WSDL files in
%SYNAPSE_HOME%\repository\conf\sample\resources\proxy.
What are this files? How can I generate them?
Thank you.
Pasquale
