With the 1.4.0 API you could specifiy a port to open a DatagramChannel on by calling the static method DatagramChannel.open(port)
http://www.infres.enst.fr/docs/jdk1.4.0/api/java/nio/channels/DatagramChannel.html#open(int)

Apparently, this method is no longer around in 1.4.1
http://java.sun.com/j2se/1.4.1/docs/api/java/nio/channels/DatagramChannel.html

What is the methodology for opening one, and how does something disappear from the API like that?

{grumble grumble}

the syntax for this is apparently
1  
2  
channel = DatagramChannel.open();
channel.socket().bind(new InetSocketAddress(port));


Still irks me though  Tongue

It not in the 1.4 JavaDocs on sun's site:
http://java.sun.com/j2se/1.4/docs/api/java/nio/channels/DatagramChannel.html
and I cracked open the DatagramChannel class from a 1.4.0 jre and it didn't have that method. You sure those are accurate JavaDocs over at www.infres.enst.fr (You know you can't trust those crazy french Smiley)

I'm rather sure you can do what you want by getting the java.net.DatagramSocket from DatagramChannel.socket() and callling DatagramSocket.bind(SocketAddress)

It was also in some NIO tutorial code I googled up (the reason I was doing it this way in the first place). Other than that, I don't know why someone would fake javadocs -- quite a mystery  Shocked

That methodology was something that you could do in the early beta's of NIO, but not something you can do in the final or later.

When she links, she links I go crazy
Cause she looks like good code but she's really a hack
I think I'll run upstairs and grab a snack!
