JSP :: How To Get Rid Of Webpage Expired Error When Clicking Browser Back Button
Jul 1, 2014
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
I got one task from my manager, regarding browser back button, refresh button. He asks me the web application has to work like Banks site... means if I refresh or click on Back button(Browser's) then it has to throw the user out of session, I checked lot in internet. But I found like only disabling back button of disabling F5 keys like that. But he’s not accepting that.
How to approach for this? Can we throw the user out of session when he clicks on browser back button or refresh button. I think its possible . But i don't know how to implement.
I have a jsp page that generate a hashtable and display its key-value pairs back to the browser. The problem is that it takes on an average about 15 minutes to build this hashtable, and as a result, I always get a timeout error. What can I do to avoid getting the timeout error without changing the server configuration for timeout
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.
I am writing code for a form in which i want to display data by selecting radiobutton.The code is working for single radiobutton but it not work when i select the other radiobutton.

the code is given below:]
private void jRadioButton1ActionPerformed(java.awt.event.Action Event evt) { // TODO add your handling code here: int LIMIT = Integer.parseInt(jTextField2.getText()); int ULIMIT = Integer.parseInt(jTextField3.getText()); { DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
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.
package userDatabasePack;
import java.sql.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Database{ //Variables private String username2, insertUser, insertPassword; private int insertUserId;
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.
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?
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.
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);
When i run a applet file in browser(IE, Chrome, Firefox) it gives a error of security risk and block the application from running. All browser are giving same error. Programme is running correctly in Myeclipse
What best API or whatever you call for browser automation? I mean clicking links, filling forms, gathering sources and other info. I already tried selenium WebDriver. It have all needed functions but there is no feature like attaching code into already opened browser so even doing google search it opens new browser window (opening takes ~5-10secs). Also I believe that there is no way that I could embed that browser into GUI.
Also tried WebSpecs and old Watij but also didnt found any way to attach or embed browser into my GUI.
So what I need is that I could create GUI with embeded browser and bunch of buttons. I click buttons then embeded browser clicks links, gets info etc.
I'm using NetBeans to create this project and I have the gui registering text boxes, but it won't retrieve what the user entered, so the calculate button returns a null exception error.
As my requirement I am storing the image link in database and through that link I need to access the image in the webpage. For this, I am storing images in my workspace. But the problem is, since my workspace is in C drive, I dont want to store those images in workspace because of the space matter. Can I store those images outside C drive and save the link in database? After that how can I access those in webpage?
Embedding an executable .jar file on a webpage. I am not a programmer and we use Blackboard Publish to package our Blackboard sessions into a standalone executable .JAR file which gives the user the full Blackboard experience. We want to embed this file on our webpage, so I did some research and I understand I have to use a Japplet (?). I have tried putting the basic (J)applet code I found on the web (modified of course) onto the webpage (see code below) but I get a 'ClassNotFoundException' error. I don't have the ability to define the files that are in the .JAR created by Blackboard Publish. How I would go about embedding this file? I can look at the files within the .jar with Winzip but there seem to be loads of .class files and I am unclear which one my webpage is trying to find!

I want to develop a dynamic webpage (using JSP & tomcat hosted on windows server) which will connect to unix server and on button "Show Files" click on dynamic webpage it should display all the files present in the unix server.
The button click should display the files which i can see when i run "ls -ltr" in unix server home directory.
So, I've seen in google mail that the webpage will automatically update whenever a new mail arrives without the user manually refresh the gmail webpage. I'm curious how this is done. Is it polling? or is it something else? how is this done in java web app?
I want to make a simple game and learn java by experimenting with it.I don't know how to increase a value by clicking it.I know how to make my objects move in my small game with mouse or keys, but I also got a score var that I want to increase per click. I can increase it over time, but after 2 hours of trying I couldn't progress any further.This is the piece of code I used, I imported the class, got getters n setters and all of that...
if(e.getButton() == MouseEvent.BUTTON3) hud.setScore(hud.getScore() + 555); Whenever I click I get an error, if I remember right "NullPointerException" is when something is missing I'm probably not targeting the value correctly... Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.tutorial.main.MouseListens.mouseClicked(MouseListens.java:22) at java.awt.Component.processMouseEvent(Unknown Source)
