Java + WinSock

[Alexis]

Hi,

Does anybody know how does Sun's java virtual machine(for Windows) uses WinSock?
Does it provide option for blocking and non-blocking?
If it does support non-blocking, what ways of handling them does it offer?
Does it use WindowsNT's IO-Completion-Ports or does it offer a similar alternative?

Thanks in advance,
Alexis

I don't believe that it handles non-blocking disk or file io for that
matter...

In fact, the SEDA architecture ( which is a decent design ) was written in
java.

http://sourceforge.net/projects/seda/

They use the NBIO library to provide non-blocking io for java.

Why they coded in java, I will never know ;)

All releases of Java have blocking I/O available. You find
non-blocking I/O in package java.nio.channels, starting with release
1.4. Java's I/O is blocking or non-blocking on all platforms, not
specific to Windows or to sockets.

So I still can't get my non cannical input on stdin :(
