Jdbc3PoolingDataSource ssl question

Hello, I am using the Jdbc3PoolingDataSource to set up a
connection pool.  I am using it in the following manner:

Jdbc3PoolingDataSource source = new Jdbc3PoolingDataSource();
 source.setDataSourceName("DB data source");
 source.setServerName("localhost");
 source.setDatabaseName("test");
 source.setUser("testuser");
 source.setPassword("testpassword");
 source.setMaxConnections(10);
...
Connection con = source.getConnection();

The problem is that I want to use ssl when connection to the database,
but I cannot figure out how to enable ssl with the
Jdbc3PoolingDataSource.  Can anyone help me?  Thanks.
