symbol: variable f
location: variable tf of type Awt

as there is a button on the website, that I need to click, but it returns a number using javascript that will access the page. Without that number, accessing the page won't work. Therefore, either I need to click the button, or return that data when I access the url. Here is the line in the html.
<a href="/missions.php?jid=11&cat=2&formNonce=49af09362db790 a6b364401c4ea52a08b515df4a&h=284e4fe4946e6fb8af3a6 62f4583454eebc8bd23" class="actionButton" onclick="return fsb11('5494');">Do It</a>
Everything is working great except for my back button at line 172. It works good but if I try to click the "insert" button again. It gives me the java.lang.NumberFormatException error. Other than that it works fine, the "insert" button still works.

I want to create a online examination system.i want to know to how to get questions 1 by 1 on the same jsp page and on clicking the submit button the result should be saved in database.
View Replies View RelatedI am getting Web Page Expired error while clicking the back button of the browser, after submitting a form. The form method is POST. ( I have to keep it that way). I tried this code
<%session.setHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "no-store");
response.setDateHeader("Expires", 0);
response.setHeader("Pragma", "no-cache");
%>
In my jsp. Still it is not working. I also tried
<script language="JavaScript" type="text/javascript">
window.history.forward(1);
</script>
In my code where the Button Action Performed is created, I have done the following to ensure that the visibility of the JTable and JScrollPane have been set to true. But it does not work?
Code below:
private void RunQueryButtonActionPerformed(java.awt.event.ActionEvent evt) {
jScrollPane2.setVisible(true);
table_001.setVisible(true);
try {
PreparedStatement st =conn.prepareStatement(SQLTextEditor.getText());
ResultSet rs = st.executeQuery();
table_001.setModel(DbUtils.resultSetToTableModel(rs));
table_001.setAutoResizeMode(table_001.AUTO_RESIZE_OFF);

I have to write a program that will generate 20 random circles with random radius lengths. If any of these circles intersect with another, the circle must be blue, and if it does not intersect, the color is red. I must also place a button on the JFrame. If this button is pressed, it needs to clear out the JFrame, and generate a new set of 20 circles following the same color rules. I am extremely new to Java Swing and am really stuck. I have everything working except the button. I cannot get a new set of circles to generate.

I am building a room management system in Java (Netbeans) and Ms Access. The jasper report is only showing code (source view) instead of design view. The GUI JFrame and Login JFrame are not displaying records in the database and the buttons are not working. Also the labels and text fields are not neatly arranged. The connection to the database is not displaying records.

Ok, so I am trying to learn about JFrames and JPanels. I have figured out buttons, layouts, etc. What im having trouble with is accessing the label object from the ButtonHandler class since it is static and I need my JLabel to be non-static so that it can change. Basically, I want JLabel to change to a pre-determined text string once a button is pressed. Here's what I have so far
package makewindow;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

why this code doesnt work? Its suppose to be a simple frame with a button that puts text to the frame when u click it. The problem is actionPerformed method, when it tries to call the stuff inside the constructor it all goes wrong. I switched the method body with a system.out.println() and it all works fine.
import java.java.awt.Label;
import java.awt.Button
import java.awt.BorderLayout;
import java.event.*;
public class TheClass implements ActionListener {

View Replies View RelatedI want to use this class and method with all of my buttons and text fields. My program contains 1 push button that adds questions and answers to a test, 2nd button that starts a test, a 3rd button that scores the test, and a text field that enters the user information. How would this work? I know how to create questions and answers, start a test, and score a test it's just a matter of how to implement the button and text fields. I'll post the code that I have done so far.
See:
private class ButtonListener implements ActionListener{
public void actionPerformed (ActionEvent event)
with all of my buttons and text fields.
import javax.swing.JFrame;
public class TestingDriver
{
//-----------------------------------------------------------------
// Creates and displays the main program frame.
//-----------------------------------------------------------------
public static void main (String[] args) {
JFrame frame = new JFrame ("Testing Program");
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

I don't get what I missed in the code. I used the example of changing the text of a button by clicking on it, but instead I also added a JLabel and tried to make the button change its text instead, but it didn't work. What did I do wrong?

import javax.swing.*;
class Buttone implements ActionListener{
JLabel label;
JButton button;
