Re: Scott's JDBC/RPG program

[Pete Helgren <pete@xxxxxxxxxx>]

I think the key issue is the IncompatibleClassChangeError that is being 
thrown.  Are you sure the jars you compiled with are the same ones you 
are using at runtime?  I'd have to go poking through the MySQL JDBC 
driver code but it looks like signature of your runtime method isn't 
matching what you compiled with.

Since this IS a java issue, you might find someone more knowledgeable 
over at JAVA400.
