Re: QTJava + other Java 1.1 JVM's than Sun's

It has to do with the AWT peers not being standardized. QTJava uses a
java.awt.Canvas for the QTPlayer and gets its peer (the window related to it) to
use. The QTJ team could support the MSJava too but it's too late (would be a
waste of their time) now that MS has legally agreed with Sun not to
promote/extend the MSJava anymore.

In Java2 there's the JAWT API which is still optional for a JVM implementor
which is the suggested way for accessing the window handle of a Canvas. The
technique it's using is similar I think to what Sun Java1.1 was using. So I
assume at least the IBM JavaVM 1.3 (is there an 1.4 from them too?) on Windows
is supporting JAWT now. Don't know about other JVMs (to say the truth I haven't
heard about other 1.3+ JVMs for Windows)

As for the Mac, MSJava for the Mac was a different beast, MS agreed with Apple
since sometime now to support MRJ in IE/Mac as the default JVM. I don't assume
you'll hear anymore of MSJava for the Mac or for any UNIX platforms.

MS has the J# language now if one is interested in Java + MS technologies, but
that's not a JavaVM, it's a compiler that compiles Java source to bytecode
(classes/assemblies/etc.) for the .NET platform. You might see QTJava.net
sometime in the future (or maybe .net@Mac first).

cheers,
George
