Re: Scott's JDBC/RPG program

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.
