[sctp-dev] Use SCTP with Java 1.6?

[Christopher Hegarty - Sun Microsystems]

Hi Dennis, Michal,

I added a page to the sctp project site [1] 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 
experience.

-Chris.
