Hello

Within the web service architecture can someone briefly explain what
the following are used for, how each are created, and whether any are
optional :-

wsdl file
disco file
proxy file

Many thanks

wsdl is a skeleton representation of the remote methods and classes, how to
contact them etc.
disco is for automatic discovery of available services on a given server
proxy is a stub file, containin the remote implementation of the methods
described in the wdl file

WSDL = Web Service Description Language. This is an XML file that describes
the web service. There are very few instances where someone writes this by
hand, as each vendor has a tool to create it. Consider WSDL the contract for
the service. Once published, you should not change exposed methods.

DISCO - discovery. This is the file that helps .NET discover local services.
Technically, I guess it could be used more widely than this, but UDDI is the
current req for universal discovery of services. UDDI is basically putting
your service into a centralized repository of services.

Proxy - a .NET created class that simplifies connecting to a web service.
The tool used to generate this class is WSDL.exe.

Hope that helps!!
