java os x enumerate windows/window locations

I'm familiar with using ffi+jruby to enumerate windows/window location开发者_运维问答s in java+windows by calling into the windows api's...anybody know how to do such a thing in OS X (enumerate windows, their locations, titles et al)?

Thanks!

How can I programatically move one Terminal.app window to another space?

How do I get a list of the window titles on the Mac OSX?

Do you have to use some accessibility API or something...
