Number format exception at the remote PC : what could be the reason?

Question

There is strange thing happening.

When the following servlet is called with the url : http://localhost:8080/Football/InsertTeam?p1_name=hkh&p2_name=klhjk&p3_name%E2%80%A6er=79&p4_name=aa&p5_name=ss&p6_name=hh&p7_name=dd&p8_name=ee&p9_name=kk&p10_name=ll&p11_name=bb&p1_number=1&p2_number=3&p3_number=9&p4_number=5&p6_number=7&p7_number=8&p8_number=9&p9_number=8098&p10_number=7979&p11_number=79&teams=brazil+vs+germany

at my machine, it works fine but it gives the following exception at other machine:

Except the port numbers (running on 8081 on mine and 8080 on another), everything is the same.(Both are running tomcat)

What could be the reason for this strange happening?

public class InsertTeam extends HttpServlet {


@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    String p1Name = request.getParameter("p1_name");
    String p2Name = request.getParameter("p2_name");
    String p3Name = request.getParameter("p3_name");
    String p4Name = request.getParameter("p4_name");
    String p5Name = request.getParameter("p5_name");
    String p6Name = request.getParameter("p6_name");
    String p7Name = request.getParameter("p7_name");
    String p8Name = request.getParameter("p8_name");
    String p9Name = request.getParameter("p9_name");
    String p10Name = request.getParameter("p10_name");
    String p11Name = request.getParameter("p11_name");

    int p1Number = Integer.parseInt(request.getParameter("p1_number")); // GIVES AN ERROR HERE
    int p2Number = Integer.parseInt(request.getParameter("p2_number"));
    int p3Number = Integer.parseInt(request.getParameter("p3_number"));
    int p4Number = Integer.parseInt(request.getParameter("p4_number"));
    int p5Number = Integer.parseInt(request.getParameter("p5_number"));
    int p6Number = Integer.parseInt(request.getParameter("p6_number"));
    int p7Number = Integer.parseInt(request.getParameter("p7_number"));
    int p8Number = Integer.parseInt(request.getParameter("p8_number"));
    int p9Number = Integer.parseInt(request.getParameter("p9_number"));
    int p10Number =Integer.parseInt(request.getParameter("p10_number"));
    int p11Number = Integer.parseInt(request.getParameter("p11_number"));

    String teams = request.getParameter("teams");

    Team teamMember1 = new Team();
    teamMember1.setpName(p1Name); teamMember1.setpNumber(p1Number); teamMember1.setTeams(teams);

    Team teamMember2 = new Team();
    teamMember2.setpName(p2Name); teamMember2.setpNumber(p2Number); teamMember2.setTeams(teams);

    Team teamMember3 = new Team();
    teamMember3.setpName(p3Name); teamMember3.setpNumber(p3Number); teamMember3.setTeams(teams);

    Team teamMember4 = new Team();
    teamMember4.setpName(p4Name); teamMember4.setpNumber(p4Number); teamMember4.setTeams(teams);

    Team teamMember5 = new Team();
    teamMember5.setpName(p5Name); teamMember5.setpNumber(p5Number); teamMember5.setTeams(teams);

    Team teamMember6 = new Team();
    teamMember6.setpName(p6Name); teamMember6.setpNumber(p6Number); teamMember6.setTeams(teams);

    Team teamMember7 = new Team();
    teamMember7.setpName(p7Name); teamMember7.setpNumber(p7Number); teamMember7.setTeams(teams);

    Team teamMember8 = new Team();
    teamMember8.setpName(p8Name); teamMember8.setpNumber(p8Number); teamMember8.setTeams(teams);

    Team teamMember9 = new Team();
    teamMember9.setpName(p9Name); teamMember9.setpNumber(p9Number); teamMember9.setTeams(teams);

    Team teamMember10 = new Team();
    teamMember10.setpName(p10Name); teamMember10.setpNumber(p10Number); teamMember10.setTeams(teams);

    Team teamMember11 = new Team();
    teamMember11.setpName(p11Name); teamMember11.setpNumber(p11Number); teamMember11.setTeams(teams);

    Configuration configuration = new Configuration().configure();
    SessionFactory sessFact = configuration.buildSessionFactory();
    Session sess = sessFact.openSession();
    Transaction trans = sess.beginTransaction();

    sess.save(teamMember1);
    sess.save(teamMember2);
    sess.save(teamMember3);
    sess.save(teamMember4);
    sess.save(teamMember5);
    sess.save(teamMember6);
    sess.save(teamMember7);
    sess.save(teamMember8);
    sess.save(teamMember9);
    sess.save(teamMember10);
    sess.save(teamMember11);

    trans.commit();
    sess.close();

}

}

PS: Other machine being remote, it has been difficult to debug.

Answer 1

There's no p3_number is your URL, which means the following will throw an exception :

int p3Number = Integer.parseInt(request.getParameter("p3_number"));
