Wordpress 1.5 supports various XMLRPC operations by default ( MT & Blogger APIs for example ) however the two shown below are "demo" operations that all Wordpress installations should support and require no authentication.

To run this example you will need to include the dependencies - Apache XMLRPC & Jakarta COMMONS Codec - however if you are lazy, here is my "xmlrpc-2.0-dep.jar" JAR containing both.
