        } catch (Exception e) {
            out.println( "<h1>exception: "+e+e.getMessage()+"</h1>" );


It seems to be the problem with the line

Connection conn = DriverManager.getConnection("jdbc:postgresql://localhost:8080/Employee", "rtz_jhay","kudeta7");

You are trying to connect the d/b on port 8080. This port is generally used by web-servers. Try to find the port on which you can connect to postgresql. The default is 5432

Hope this helps
