The market emphasis on the Internet and applets has lent confusion here. Java can be used to write applets or stand-alone applications. It's a full-featured programming language. The difference between an applet and an application is something to do with the class upon which you base things. If you use the applet class, it's an applet, Otherwise, no. (This is a very simple-minded explanation—I'm just starting, too.)

There are JDBC things being developed for the AS/400. Some of this is included in the AS/400 Toolkit. This should be something like ODBC in application, I'd think—once you specify the back end, everything else :-) falls into place.
