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.
