Old-style (non-WSDL) Web Service

Guys,
I was given just the schema file and an URL to point to, and no WSDL. The guy even replied "WS-what?" when I asked him the WSDL.

A friend of mine told me it's the "old-style" Web Service, simply HTTP POSTs containing XML SOAP in the body. How do I access such service in Spring WS? Thanks in advance.

You don't need a wsdl to access web services with spring-ws. All you need to do is to feed your WebServiceTemplate with the uri of the service either by setting the defaultUri property or by invoking one of the send* methods (or marshallSend*) that accepts one.
