It looks great!!! :-)
I just executed the simple test (com.sun.nio.sctp.SctpChannel sc =
and it is working!!
Thanks a LOT,

Hi Dennis, Michal,
I added a page to the sctp project site  with, what I believe are
detailed, instructions of how to use SCTP with JDK6. Please take a look
and try them out.
If you encounter any problems of find something lacking from the
instructions then please let me know. If the instructions are sufficient
and you getting it running without any problem, please let me know you
