Ok, thanks... I managed to get it to work using the simple commands:
$ gcj -c MYLIB.java (creates MYLIB.o)
$ gcj -shared -o MYLIB.so MYLIB.o (creates the shared object MYLIB.so)
$ gcj -c MyApplication.java (creates MyApplication.o)
$ gcj --main=MyApplication MyApplication.o MYLIB.so (links MyApplication 
with MYLIB.so)
This is of course trivial - but maybe some will benefit from having it 
here now... :o)
However, doing so with my gcj (3.3.1 (cygming special)) under cygwin 
will result in the following error:
collect2: ld terminated with signal 11 [Segmentation fault], core dumped
/cygdrive/c/src/lib/MYLIB.so(.text+0x0):crtstuff.c: multiple definition 
of `___do_sjlj_init'
/bin/../lib/gcc-lib/i686-pc-cygwin/3.3.1/crtbegin.o(.text+0x0):crtstuff.c: 
first defined here
But compiling and linking with my (cross)gcj-3.4.0 works fine...
