On the Advanced tab, you can configure the following connection factory type properties. If you make changes, click Apply, then Synchronize to update the Ant configuration script:
connectionClass The fully-qualified name of the class that implements connection management.
djcClassLoader The name of the custom class loader, which reloads classes when you refresh the connection factory type. If not specified, classes are loaded by the Java system class loader, which means you must restart the server to use new versions of the classes.
managedConnectionFactoryClass The fully-qualified name of the class that implements the managed connection factory.
