That's exactly what I'm doing now for the same reasons. My core data access classes (StatementUtils) just take commands and parameters. All the JDBC work is out of view of the business classes. They just pass an command and an object to populate and get back an object or collection of objects. The business classes get the commands by passing a token to method that accesses a Properties file. Right now, the Properties file returns SQL commands, but if they needed to be something else, this could be changed without recoding the business classes. You'd have to import a different StatementUtils class, but so long as it used the same interface, it would plug and play. -Ted. -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
