Where/what is a good reference to learn how to access JDBC from RPGLE?
I have a RPG developer that needs to access MS SQL Server data.  Having 
totally gagged on the price of IBM's suggested solution, and not really 
having a whole lot of luck with one third party solution, and REALLY not 
liking the idea of putting software on each SQL server we want to access, 
we decided to evaluate using RPGLE to call JDBC to get to the data.  How 
best to learn how to do this?  This developer supposedly took a brief java 
course.

Also any suggested reference materials?  Perhaps the following:

JDBC and Record Level Access with IBM AS/400 Toolbox for Java
by Joe Pluta
Book sounds pricy, but it's supposed to more of a course than a book.  The 
second url explains that better (but doesn't give the discount or the 
kickback to this wonderful list).
