org.postgresql.Driver doesn't implement the javax.sql.DataSource interface.

If you want a DataSource, just use "new 
org.postgresql.ds.PGSimpleDataSource()" or "new 
org.postgresql.ds.PGPoolingDataSource()" if you want pooling.

If you don't want to use a DataSource, you should be doing:

Class.forName("org.postgresql.Driver");
Connection conn = DriverManager.getConnection("jdbc:postgresql:....");
