createConnectionFactory

protected org.apache.commons.dbcp.ConnectionFactory createConnectionFactory()
                                                                     throws java.sql.SQLException

Fixing a bug within BasicDataSource.createConnectionFactory() for driverClassName to have real effect.

Because we use currently Apache Commons DBCP 1.4.0 that has a bug not considering driverClassName, thus, we're unable to create a JDBC driver using a user-provided driver class name (we try to do that by setting explicitly a value for openJpa.connectionProperties="DriverClassName=..."), unless we perform the exact same fix that is applied by the DBCP patch.

Note: when DBCP 1.4.1 will be released, and Oozie will update to 1.4.1, we can remove this class.

Please see the DBCP bug and #L1588-L1660 the fixed method for details.

Please also see how OpenJPA is integrated with DBCP.

Throws:
