Does the client proxy internally sends its address to the server when making a call ?

Question

We have a WCF service , with ABC as 'Server_abc' Now , we created a proxy on the client side and made a call on the server. My understanding is that the poxy will have the 'Server_abc' of server and make a connection internally and exucute the code.

The Question is

Does the poxy create a hidden service on the client side and send the Client_abc to the server when a call is made ? other wise how is the response from the server comming to the client for a normal method call (request -response) ?

Also a general doubt

If my service is WCF but if the client is java , the proxy created at the client side will be java_Proxy ,now how is this call coverted and received at the server side .

The client doesn't create a hidden service, all it does is serialize the request using the specified binding and send it over the wire using low level classes such as WebRequest for example. All this internal plumbings of course are hidden so that you don't have to worry about them and it looks as if you were calling a local function. The server on the other hand does the same serialization and sends the response which the client deserializes back to objects.

This will depend on what binding the service is using. For example basicHttpBinding is compatible and JAVA clients will have no problems serializing the objects into XML and sending them over the wire to your service. If you the other hand your service uses for example a netTcpBinding, only .NET clients will be able to call it. Here's a comparison between the different bindings.
