To connect do something like this:

    Connection c = DriverManager.getConnection("jdbc:postgresql://hostname/dbname", "username", "passwd");
    Statement s = c.createStatement();
    ResultSet r = s.executeQuery("select * from test_table");
catch(SQLException e)

I'm able to run this on the local box, but only with jdbc:postgresql:dbname...
the //hostname/ piece i tried substituting //localhost/ and that didn't fly...and what i really need is something from another server, so need to access remotely (tcp/ip port 5432).
Tell me correct format for that and I'll be happy to accept your answer!

What error do you get when you try to connect to a remote database?

Try specifying the port number or IP address in the connection string.
