gstreamer-java don't work with GCJ

Mon Aug 13 11:50:00 GMT 2007

Hello!
I'm new here and i have my first problem(s). :D I tried to use
gstreamer-java binding from
http://code.google.com/p/gstreamer-java/source and get errors from
libgcj8 ... gstreamer Java uses JNA instead JNI.
If there any way to go? And why the gst-java project from freedesktop
has been stopped???
here is the output:
init:
deps-jar:
compile-single:
run-single:
