Q:
java webservices fundamentals
Web services, WSDL, Java, Java Web services
I have a fundamental question regarding java webservices.

Client side stubs has the following role:
1. Convert java object types to xml types and create soap messages
2. Handle communication from client to webservice and vice versa

SOAP message will differ depending upon the style and use parameters of webservice. My question is do client side stubs connect to wsdl and get style and use parameters at runtime from WSDL or is the information coded when the stubs are generated. I guess that a stub will have the information when it is created and if we change style/use parameters we need to create the stubs again. If this is the case do we need WSDL to call a webservice, since client has the stubs to connect to webservice.

Thanks,
Pawinder

Hi Pawinder,
The Client stubs will not connect to wsdl to get the style and parameters , it will be coded when you generate the stubs using the WSDL file.
We dont need WSDL to call a webservice, wsdl is just defintion language .
Hope this clarifies your doubt.

Thanks for your answer, Usman. It clears the doubt. This implies that if we change the style/use tags of the webservice, we need to regenerate the stubs.
