Green Light for Java!

Good news.
I've been given the green light to use Java in our shop.
Now what do I do?
Seriously, I need to identify the most logical place to start.
I'd like the first Java program to make a good impression.
Any suggestions?
Platforms: AS/400, NT.
DB: DB2/400, MS Access

I think you should develop on NT because it seems that is the environment that the newest and best JVM's come out on. When you have your product developed, you should have a decent selection of VM's on almost all the other environments.
Database - have you considered an object database?

What means it, object database?

A whole new way of data storage and retrieval. Based on the idea of a persistant object.
Rather than mashing your objects into records and having to change your storage techniques every time you tweak a class, you simply have an object that refers to all of your data. Maybe a huge vector or hashtable. When you ask your enormous hashtable about "Ray Marsh" the object database works behind the scenes to pull the object up from the hard disk (or over the network, or whatever). For you the programmer, it seems like your 20 gigs of data is all in memory, but in reality, only tiny bits of it are.
It's the way all data will be stored in the future.

Sounds interesting.
Any tips on vendors or information sources for ODBs?

Apparently, the new J2EE (free from sun) comes with something called CloudScape that's an ODB.

Cloudscape is also exptremely easy to use!! (trust me I know very little about OO and Java but I use Cloudscape without too many problems)

Please see http://www.javaranch.com/ubb/Forum9/HTML/000025.html for a continuation of the thread regarding UML.
 
It is sorta covered in the JavaRanch Style Guide.
