Believe it or not, what those do is call out to the cibadmin,
crm_resource, and crm_attribute binaries.

There's a C API via libcib. There's been talk before about SWIGifying
that, and then be able to generate bindings for anything that SWIG
supports (including Java), but nothing of that sort has materialized up
to this point.

Andrew will correct me if I'm wrong, but as far as I know there is none.

You can try tooking at LCMC as that is a Java-based GUI that should at
least get you going.

But perhaps you have the experience (and bandwidth) to take on the SWIG
task?
