I’m studying servlets and I’m trying to create a small program to get the hour through a class that I’ve created. But I’ve bee getting a exception. Here is the code:
User
package Business;
public class User {
private String userId;
public User() {
userId = "";
}
public User(String id) {
userId = id;
}
public void setUserId(String id) {
userId = id;
}
public String getUserId() {
return userId;
}
}
Hours
package Business;
import java.util.Calendar;
import java.util.GregorianCalendar;
import business.User;
public class Hours {
private User user;
private Calendar cal = new GregorianCalendar();
private int min = 0;
public Hours(User user) {
this.user = user;
min = cal.get(Calendar.MINUTE);
}
public String getMinutes() {
return Integer.toString(min);
}
public User getUser() {
return user;
}
}
CheckUser
package process;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import Business.User;
import Business.Hours;
public class CheckUser extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String userId = request.getParameter("userID");
User user1 = new User(userId);
Hours h1 = new Hours(user1);
String url = "/show.jsp";
request.setAttribute("hours", h1);
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url);
dispatcher.forward(request, response);
}
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String userId = request.getParameter("userID");
User user1 = new User(userId);
Hours h1 = new Hours(user1);
String url = "/show.jsp";
request.setAttribute("hours", h1);
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url);
dispatcher.forward(request, response);
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String userId = request.getParameter("userID");
User user1 = new User(userId);
Hours h1 = new Hours(user1);
String url = "/show.jsp";
request.setAttribute("hours", h1);
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url);
dispatcher.forward(request, response);
}
}
