Re: [Jython-dev] select module workaround

[Kevin B. <kb...@ca...>]

This is a case that shows the client-bias Java is trying to overcome.

You have a couple of choices for asynchronous IO in Java:

1) wait for JDK1.4: use JDK 1.4's new asynchronous IO APIs: http://java.sun.com/j2se/1.4/docs/guide/nio/index.html

2) limit scalability: use lots of threads that block on the JDK 1.0-1.3 synchronous IO methods

3) limit portability: use a native library that implements the asynchronous IO functions you need (either custom-written or one of several that are available)

:-(
