Ernst de Haan writes "This fifteen minute tutorial shows how to get started with XINS, a unique Web Services technology that combines REST, XML-RPC and SOAP. The approach is similar to Ruby on Rails; all you need to do to get started is edit some config files and write a few lines of Java code. Then you will have a fully-functional WAR file you can deploy in any Java servlet container.
The article is written using Linux, with KDE screenshots. XINS works on all Java 1.3+ platforms, including Linux, Solaris and even Windows ;-)
A fairly complete user guide is available."
