BTW, I concur with everything you say in the above

Sun has an integrated development environment called Java Workshop. Version
2 is in beta and it's free for now. It looks pretty nice.

IBM's Visual Age for Java is another one. It's received very positive
reviews, and I agree. The AS/400 Toolkit for Java is supposed to work with
it, too, at least the commercial version. An entry-level version is
available on the Web, and it's also free. The standard version can be had
for less than $100 US. It is really an amazing IDE, letting you drag/drop
not only controls but also connections between them. Check out the August
NEWS/400 for a quick HOWTO. Start at one of the following to get more
information:

Sun has a tutorial, available at their home Web site

        http://www.javasoft.com

or

        http://www.javasoft.com:81 (for a Java-driven version)

in HTML format. You can download it and run it from your own machine or
network. There are some typos, so watch out. (The _first_ example has
square brackets in the wrong place in the main function--they're supposed
to follow 'args'.)

I like anything by Gary Cornell--he's written some excellent Visual Basic
books, too. They had the same practicality and whimsy.

Right on!
