I am trying to finish this servlet that adds a new course to my courses display. im using a check box so the user can pick what the prerequisite are for the new course they want to add. so if they check cs201 , it will add cs201 as a prerequisite for that new course.
for some reason my checkbox will only add the first checkbox that is clicked. like if i add a subject , and click the check boxs for cs203 , cs202, and cs201. it will only grab cs201 and add it to my course display. it wont grab all 3. how can i grab the other info thats checked?
What I want is ..on selecting heading check box...all the below check box should get selected....and clicking on delete button which i will create later on...i want multiple rows to be deleted from database....

I am trying to use three cookies in a servlet to store the background and foreground color and text size but my code is not working for some reason. When I run the servlet I get an IndexOutOfBounds exception and in my code is says my cookies are not ever used, when they should be to store the variables?
I am adding my shopping cart in session like bellow in servlet
HttpSession session = request.getSession(); session.setMaxInactiveInterval(60*30); // 30 minutes if (session.getAttribute("cart") == null){ session.setAttribute("cart", new ShoppingCart()); } cart = session.getAttribute("cart");
I seems if more than one person accesses it from server, if they items in the shopping cart, all the product is added to a single session. I mean if i added 4 items first and other person adds 2 items, second person sees 6 products in his cart. Where am I going wrong?
I have written sample web application with servlets and jsp. As per the below code the action url should be executed automatically according to the "onload". I have written this below code in one of my servlet, The below "onload" form hits the path in action only in Firefox and IE but not in Chrome(41.0.2272.74 beta-m (64-bit)).I have seen the link [Chrome - <body onload=“”> is not working ][1] , I have my below code in the end of servelt. there is nothing to execute after this code in the servlet.
out.write("<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> "); out.write("<html><body onload="alert('alert has been fired');document.forms[0].submit()"> "); out.write("<form method="POST" action="" + actionUrl + "">
[Code] ....
Is there any reserved key words of chrome in the above action url? If I execute this code in the html format, it is working in chrome. but if it is from servlet, alert() is not running.
The output of value="${user.id}" is retrieved from a DB, it looks like this:
Id Nombre usuario Email Fecha de registro Acción 1 isaac2 @2 1986-01-01 *Delete(input) *Here there is check box 2 isaac3 @3 1988-01-01 *Delete(input) *Here there is check box
Then depending of which check box I selected then the row by the side should be selected by id and deleted.But what happens is that doesnt matter which check box I select, always the first row is deleted. I understand that at the first iteration of the loop it just take the first id, it doest attach the id I have choosen to the row it belongs to

My working Server Code extends withe JFrame..Java Code:
Why in my program keys are not working, what I forgot to write?
import javax.swing.JFrame; public class Main { public static void main(String args[]) { JFrame frame = new JFrame("Stickman"); frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE); frame.setSize(450, 490);
I am working on a fairly simple program where I have a colour change three times using the red green blue spectrum. The problem is that I keep getting a result of zero no matter what I do.
import java.awt.*; class RectangleMain { public static void main (String[] args) { ColouredRectangle blocky = new ColouredRectangle(50, 100, 20, 40, Color.red); System.out.println(blocky.getColour()); blocky.mixColour(Color.blue);
I'm programming a game, but the keyListener doesn't work. Here is the source code:
import java.awt.event.KeyEvent; import java.awt.event.KeyListener; public class InputHandler implements KeyListener{ public InputHandler(Game game) { game.addKeyListener(this);
[code]....
My Question is: Why will it not say "up", if I press "w"?
I'm having a problem where an if statement isn't working. In the Person class boolean olderThan ignores my if statement so it always returns false and I just don't get why that's happening.
import java.util.Calendar; public class Person { private String name; private MyDate birthday; public Person(String name, int pp, int kk, int vv) { this.name = name;
I have added a Simple Jar file in Eclipse Proect->BuildPath->jar file but class Inside that are not showing in My project this is my Project Structure and I have all ready checked in Order and Export..But jar file is not working.
I am learning out design patterns and doing a little fun project on Model Control View (MCV). I got the concept down, it is pretty simple for the most part. However my buttons are not working.
Here is the code:
public class Controller { private Model model; private View view; Controller(Model model, View view) { this.model = model; this.view = view;
[code]....
It runs but nothing. My other questions is how can I make a box that will print the results.
I need to find out if one array list is a sub-sequence of another. The elements in the first list all need to be in the second list and must be in the same order. So s1<n, t, a> is a sub-sequence of s2<q, n, f, r, t, d, a>, but s1<a, a, t> is not a sub-sequence of s2<a, t, a>. I need to use iterators to go through each list, and I should only go through each list once (since it has to be in the same order) so nested loops don't seem like they would work because it would start at the beginning of one list every time it moved to another element in the outer loop's list.I seem to have an issue where the itr1. next() is ignored when in an if statement.
My current code just stalls and will never stop running. I've also switched things around and put the not equal check after the if it is equal and it throws a NoSuchElementException.
import dataStructures.*; public class Subsequence3 { public static void main(String[] args) { ArrayList<Character> s1 = new ArrayList<Character>(); s1.add('n'); s1.add('p'); s1.add('a');
the problem which im facing when executing jar file is it is not working same as when i run file using the IDE.When run jar file, it won't open the new frame even the user and pass combination correct.But when i'm compiling using the IDE, it works as charm. The main menu popped up after i logged in.I've tried Clean and Build and it's not working too.
