Web Services (which are essentially standardized communication over SOAP) contain both a document-style and an rpc-style way of using web services. The RPC-style invocations are very similar to other RPC technologies. It's just based on (standard) XML, which is a lot easier from platform independence point of view. In other words, Web Services are in a way RPC. Plus some extra. So, RPC is (still) not going anywhere - in fact you could say the opposite. It's becoming more and more common.

Web services are : - Business functionalities exposed as services over internet. - A programmable application logic providing data and services to other applications over internet. - Based on Internet protocols and standards. - Based on XML standards and provides cross-platform and cross-language solution. There are two types Web-services communication styles: RPC-oriented Web services: Synchronous, point to point, not persistent Sends data formatted to a procedural call Document-oriented Web services: Data formatted as an XML document Asynchronous service interactions (like Messaging) SOAP facilitates communication in Web services. It establishes Wire protocol for communication �similar to� IIOP for CORBA and JRMP for RMI. But in case of SOAP, XML is used for data encoding as �text� based protocol. SOAP Supports XML-based RPC Web services and XML Messaging (Document oriented Web services. To add more clarity on SOAP, SOAP is NOT a component model like EJB, JavaBeans etc. SOAP is NOT a programming language like Java or C++. SOAP is NOT an alternative to distributed computing and does not replace RMI or CORBA. SOAP is NOT a solution for all ! In Java Web services, JAX-RPC facilitates RPC base Web services and JAXM/SAAJ facilitates Document oriented Web services.

whats SOAP over http and SOAP using mail ? How do u classify it as RPC or document type ? Or is the question in appropriate ?

SOAP over HTTP differs from SOAP over SMTP (mail) on the transport level (which is kinda obvious from the names In other words, the two differ from each other in the way the SOAP Envelope is encoded into the wire protocol message for transportation.

It looks like I need to do some more reading because I apparently don't understand the topic as much as I thought I did (as little as that is). Thanks for the feedback.
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
