What we have illustrated is a way to interoperate between a .NET service and a jMaki Ajax application using SOAP as an underlying communication protocol. With the growing popularity of Web 2.0, ReSTful web services supported by Yahoo, Flickr and many others have become quite popular. A ReST-style web service is accessed through URI-addressable semantics of the HTTP protocol, which significantly simplifies integration effort on the client side. As a result, the Web 2.0 services interoperability between .NET and Java stacks is gradually shifting towards ReST.
