JSP :: Disable Back Button When Logout
Apr 19, 2014
I have a website which requires login. After I enter username and password and click login button, a new page is loaded. In that page I have a username in the right up corner. When the user clicks logout button, Session.Clear() method is called and also Response.Redirect(" to login page "). It works OK, but the problem appears when I then click Back button in the browser. It gets me back to previous page with the username in the right up corner. Insted, I would like to show message asking user to enter password again so he can login properly.
What should i do at client side???

I'd like to disable/enable SelectManyCheckbox and the SelectOneMenu based on my selection. I have two radio buttons to be selected whether A or B. The SelectManyCheckbox and the SelectOneMenu should be disabled at the first run. When the user selects “A” the SelectManyCheckbox and the SelectOneMenu should be enabled and if the users selects “B”, the SelectManyCheckbox and the SelectOneMenu should be disabled and the items should be empty. I tried to use <f:ajax render="certificates"/>, but it doesn't work properly.
<h:selectOneRadio id="request" layout="pageDirection" value="#{user.hrRequest}" required="true" requiredMessage="Error: Select a Request Type">
<f:selectItem itemLabel=" Request A" itemValue="A"/>
<f:selectItem itemLabel="Request B” itemValue="B"/>
<f:ajax render="certificates"/>
[Code] ....

I have started coding recently and been working on a simple java timer. My problem is that the button does not show any response even though an action has been done via actionlistener.
Example: When I press the "Start Timing" button, it should start timing and output the counter to Static Timer but instead of doing that, it does nothing.
The important bits are under Timer code and Button Start Timing. Is their something that I'm missing?
//--- All imports have been handled ---
public class GUI {
double counter = 1;
double inputA = 1;
int delay = 1000;
Timer timer = new Timer(delay, null);
[Code] ....

I 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>

I am learning Java but have a strong C# background. I am trying to figure out the syntax to do this in Java. In C# I would do the following to enable all text boxes in a panel
private void EnableAll() {
foreach (Control ctrl in Panel1.Controls) {
if (ctrl is Textbox)
((Textbox)ctrl.Enabled = true;
}
}
Is there something similar I can do in Java to do the same thing.

I'd like to enable/disable a jpanel and it's entire contents in one fell swoop. I could of course call each component's .setEnabled() method, but I figured there must be a better way!

I've searched everywhere but found no way to disable loading of images by Java WebEngineHow to do it?
Research done:
I found some ideas, such as using URL.setURLStreamHandlerFactory() to use my own URLStreamHandler, and having that analyze the URL to only return URLConnections for URL's that don't end in .jpg .png etc.
But that has many problems: Sometimes the image url doesn't end in .jpg, if it's a dynamic image, such as a captcha. So how can I disable automatic image loading from WebEngine?

Is there a way to disable sorting by clicking on the JTable headers?I have tried a few ways but because I am sorting the data when I load it that 'breaks' that also. Here is what I am trying to achieve.
Sort by 3 columns:
table.setAutoCreateRowSorter(true);
table.getRowSorter().toggleSortOrder(6);
table.getRowSorter().toggleSortOrder(7);
table.getRowSorter().toggleSortOrder(5);
table.getRowSorter().toggleSortOrder(5);
but then I want it so the user cannot resort that when the table is displayed..

I have in my application a button that when it is pressed, runs a long running task (usually takes a couple of seconds....).
My problem is that while the task runs, I want to stop the button from receiving clicks. Unfortunately this is something I have not achieved.
I have tried creating a new thread and calling the long running method, and using the Display.geCurrent().asyncExec...
Examples of what I have tried so far:
myButton.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
if (myList.size() > 0) {
myButton.setEnabled(false);
myButton.setGrayed(true);
[Code] .....
In both cases, while the button is disabled and the cursor busy, if the user clicks the button, the long running method is ran several times - and this is what I want to avoid.

Is there a way to achieve this? Using setDisable(true) deactivates the entire control. I want the drop down menu items to still be accessible, but the action area visibly inactive.

The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.
import java.awt.BorderLayout;
import java.awt.EventQueue;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.SwingConstants;

I've been putting together an addressbook and try to work on some idea but I have hit a bit of a wal early on, and Im sure the problem is easy to resolve, I just can't get the old brain to do it.At present I have 5 classes
PersonDetailsAdressDetailsAddressBookAddressBookGUIEnterDetailsPanel
I have taken EnterDetailsPanel out of the main GUI code, as I plan, or had planned on using additional JPanels for the other options of the application until I got stuck. What I want the EnterDetails panel to do, which it does so far is to have the user enter all of their information and when the button is pressed it will then create a PersonDetails object and here is where my problem is. how to get the object from the panel back across to the GUI which initalises the AddressBook class in the constructor and add it to the List via an addDetails() method.
If I create a quick method in the AddressBookGUI class I can add the object to the List fine, I'm guessing this is because I have created a new instance of the AddressBook in here already via the constructor, however if I add an AddressBook reference in the EnterDetailsPanel I get a nullpointerexception for the opposite because it's not been created in there.These are what most of the classes do so far.
PersonDetails has a reference to the AddressDetails and holds all information for that person.AddressBook contains a List that accepts PersonDetails and has methods to add/remove the person.AddressBookGUI creates a new instance of the AddressBook class along with the general gui things. EnterDetailsPanel is added to JTabbedPane in the GUI class and allows the user to enter their details and submit those via a button which will then create a new PersonDetails object that I am trying to get added to the AddressBook class List
