If you put the jdbc3 driver in your classpath instead of the jdbc4 driver, and if you make sure to avoid calling methods existing since JDBC4 in your code, everything should work flawlessly. These properties can be used to describe how pooledConnection objects created by DataSource objects should be pooled.
