JDBC and DriverManager

Okay...the below code compiles fine, but when it runs, it throws the
SQLException at the DriverManager line (as you can see, everything below
is commented out). There is indeed a datasource "bugs", and PostgreSQL
is running on the local machine. There is no password needed to access
the database, and I can access "bugs" interactively with psql. Am I not
importing a package...?

I need help...am lost to why it throws the SQLException.
