(Java) Making SOAP Requests using the REST API

There's no reason a SOAP request cannot be sent using the REST API. It's only a matter of adding a SOAP specific header, and providing the SOAP XML request body. The response body is the SOAP response XML.

This example sends a request to ws.cdyne.com to get city weather by zip code.
