How do we set the classpath?  We don't really want to use
the system's environment classpath because it is different than what we
need and it doesn't seem like a good idea to add a bunch of unless
classes & jars just to execute the single class.

You shouldn't need to modify the classpath at all to use Java in stored 
procedures. The classes you need either need to be in the 
/QIBM/UserData/OS400/SQLLib/Function directory (in the appropriate 
subdirectories if part of a package) or in JAR files registered to the 
database. To do that, you use a procedure called SQLJ.INSTALL_JAR and it makes 
that JAR file available to all stored procedures or user defined functions. It 
essentially adds the JAR to the database classpath, which is separate from the 
system classpath.

Do a search on Google or IBM's site for the "IBM Developer Kit for JAVA" pdf. 
There's a section called "Java SQL routines" that will tell you everything you 
need to know about getting started.
