WSDL for only client server model?

[suresh Thiriveedi]

Hi,

I'm a new bee to this web services and wsdl world. Need to develop an application which is not completely client server. Server can also update few things on it own to the client with out a request from the client. I mean two servers exchange the messages through this interface.

This case I can use "WSDL" as the interface doc?I see in the example "wsdl" doc, only the list of "services" at the bottom and looks like we can create a client from this wsdl and client can call this services and expect the responses. But how to implement the above model using soap/wsdl where wsdl can be used as an interface to exchange messages (req/resp) in either way.

Any pointers are highly appreciated.

Thanks in advance
Suresh
