Try adding some debug info (will help us see what is going on) - e.g:


  Class.forName("org.postgresql.Driver");
  String url =
"jdbc:postgresql://localhost:5432/postgres?user=postgres&password=major";

  Properties props = new Properties();
  props.setProperty("loglevel","2");

  Connection conn = DriverManager.getConnection(url, props);
