A web service can either use the document or the rpc style. To set the style used in your web service, provided that you use a code-first approach, you can use the style attribute in the @SOAPBinding annotation. Allowed values are found in the enumeration SOAPBinding.Style.
Regretfully, I do not have any links to example of JAX-WS RPC web services, but will get back if I find one.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
