What is the recommended Java API for creating new/editing WP posts?

I’m attempting to integrate my Java based web app with WordPress. I’d like to be able to create new posts as well as edit existing ones.

There seems to be limited info in the online documentation (http://codex.wordpress.org/XML-RPC_Support) on what packages/classes to actually use to do this.

The Blogger API seems to be deprecated due to Google’s aquistion of Blogger.

Has anyone used the Google API to do this? Is there a good starting point to look at for using the other supported APIs?

Clearly this has been done before (see: All those various clients that allow posts to be created, edited, etc) and I’m sure someone out there can point me in the right direction.

Thanks.
