Yes, Java _can_ run on the 400. There is a preview release of the JVM (Java
Virtual Machine) available at
<http://ncc.hursley.ibm.com/javainfo/hurindex.html>. This is only available
for RISC boxes. If you're on v3r7, get the one for v3r7/v4r1. If you're on
v4r1 and don't have the Common Programming API (CPA) product installed, you
won't be able to use the JVM yet—they forgot to put the v4r1 version up for
downloading—said they'd have it in a few days—a few days ago!

With the AS/400 ToolKit for Java, you can do record-level access to AS/400
data. This set of Java classes is available at
<http://iws.as400.ibm.com/toolbox/javatool.htm>.

The answer here is the same as above—the AS/400 ToolKit for Java. The
classes can be run either on a client or native on an AS/400. You must be
sure not to use AWT classes (part of Java, not the ToolKit) on the 400,
though, since those are for graphical interfaces.

We're all new to this one—welcome to the fun!
