Attention: Derby Version 10.2 includes JDBC 4.0 functionality based on a pre-release of Java SE 6. When you use Derby with a Java SE 6 virtual machine, Derby will use its JDBC 3.0 drivers, just as with 1.4 and 1.5 virtual machines. JDBC 4.0 is available only to developers who download Java SE 6 and use it to build in support for JDBC 4.0. The Release Notes explain how to build the JDBC 4.0 functionality with Derby Version 10.2. A follow-on Derby release will include JDBC 4.0 functionality based on the final JDBC 4.0 specification once Java SE 6 becomes generally available.

JDBC 4.0 introduces a simpler mechanism for iterating through a table. You use this mechanism by passing an annotated query to your DataSource's createQueryObject method. To expose this createQueryObject method, Derby adds new JDBC 4.0-specific DataSources. Use these DataSources if your application runs on JDK 1.6 or higher.
