Soap Webservice Transparent WSDL change

I have a webservice [call it S1] exposed and clients call that service and get back respons开发者_如何学编程e.So good so far.

I have to change my WSDL a bit [for some very odd reasons] but i dnt want clients to see the change. So my idea is to intercept the soap request somewhere b/w server and client and interceptor should modify the soap request and forward to the server.Similarly on response , again interceptor should intercept the request and change some property name and send it to the client.

Any idea how to do this? One approach IMO is to use handlers but here i dont have control over how server generates service from WSDL. How can ESB help in this?

Please see its realtime application with huge requests to and from server!!!

An ESB like Mule ESB can help by acting as a proxy for your web service.

Can you not write a new web service with the new wsdl, then alter the old web service to simply call the new web service. A bit like overloading a method. That way you can have V1 and V2 web services.
