Yeah, well when you do that you're not creating a shared library, just
an object file!

That sounds about right. You can of course create shared libraries with
ld, as long as you give it the right options to tell it to make a shared
library. Its easier to do it with "gcj --shared". Note that you can also
do something like "gcj --shared *.o -o my-package.so".

Read the bit about Class.forName(). gij is essentially just a front end
to the "Class.forName()" call. We'll try to document this better in the
gcj manual, hopefully before the release.
