Hi Daniel,

libgcj does not yet support JNI, but support is planned I believe. Of course
gcj should happily _compile_ a classfile that uses JNI, as native methods are
specified in the same way. You just need to {port/implement} the native part
of the class {to/using} CNI.

I find that CNI is actually a lot simpler than JNI, and it is well documented.
It is also more efficient (ie faster) than JNI, apparently.
