Web Service providers
The Borland web services engine includes a number of providers. A provider
is the link that connects a client web service request to the user's class on the
server side.
All providers do the following:
■
Create an instance of an object on which they can invoke methods. The
exact way of creating this object differs from provider to provider.
■
Invoke the methods on that object and pass all the parameters that the
XML client sent.
■
Pass the return value to the Axis Runtime engine, which then converts it to
XML and sends it back to the client.
