hi,
Basically a proxy object is the basic concept of invoking web service.
the first step in creating a Web service client have create a proxy object. Then only we can use multiple platforms (i.e. WAP clients, PDAs,Web browsers,and SOAP clients).
To consume a web service at client level you need proxy to communicate with web service in a easiest manner. A client and a Web service can communicate using SOAP messages, which capsule input and output parameters as XML. A proxy class pass parameters to XML elements as input and then sends the SOAP messages over a communication network. the proxy class frees the client from having to communicate with the Web service at the SOAP level and allows you to invoke Web service methods in any platform that supports SOAP and Web service proxies. This proxy proxy class interoperability.
In NET Framework There is a utility called Wsdl.exe. That we can use to create a proxy Web service object.we can create proxy from Visual Studio command prompt.
i hope you clear about the necessity of creating proxy for web service.
Enjoy the article........Keep on postings..
