OK, so we know the DB is accepting connections- that's progress...


This URL doesn't look quite right to me.

assuming the database name is "company" Try changing this to:

       conn = DriverManager.getConnection(
 "jdbc:postgresql://192.168.1.103/company",
                                          "postgres",
                                          ""       );
