RE: does anyone post to this list?

I've played around with Remote AWT serving an NT Workstation. It's wonderful
to behold the AS/400 delivering up GUI from a native language without any
intemediate 'client/server/microsoft' stuff! It's a little slow at present
and IBM does not recommend for heavy-duty GUI applications at present. Also,
you would need to be aware that Remote AWT uses RMI, and so you must be
running a JVM on the client which supports RMI. IE 4.0's JVM  does not
support RMI. Theoretically, though, you could use Javasoft's 'Java Plug-In'
to automatically make your applet run Javasoft's JVM and then spawn a thread
to initiate the Remote connection. Once initiated, of course the AS/400
takes over serving up the GUI to the workstation. I should stress that I'm a
novice in this area, so your best bet would be to check the red book at
http://www.redbooks.ibm.com/abstracts/sg242163.html

On the question of how good Java is on the AS/400, I had a chat recently
with the lecturer at a Java evening course I'm attending. He works as a
software engineer at a very well known Java software company with here in
San Francisico. When faced with the task of implementing their software on
the AS/400, any skepticism vanished when all of their thousands of Java
classes compiled successfully and ran perfectly on the AS/400. In contrast,
his regression testing with a new version of Microsoft's Java compiler
(JVC), revealed that Microsoft had introduced a couple of extra keywords to
its compiler causing the compiler to blow up because almost every java
source had a variable the same name as one of these keywords! So they had to
change their source code for the new release of JVM.

Hope this helps.
