JSP :: How Bank Sites Throw User To Session Expire Page By Clicking On Browser Refresh / Back Buttons
Jun 20, 2012
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 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 want to send user back to the Login page after idle time of 10 secs. If user clicks again on screen before 10 secs are over, time will automatically reset to new 10 sec and so on...
imagine I build this this device that takes in impulses... 0 and 1..but I need an interface with buttons to decide when to throw a 0 or a 1...would java be a good language to control this?I'm having difficulty to make this path... interface to circuit...
May be I did not understand the meaning and usage of attribute "session" in page directive. My understanding is if session=false, in page directive, then the JSP page will not participate in the session. However, I have my welcomepage as below:
I am developing a e-commerce college project, here i add the items in the cart(a div tag in the jsp page) via servlet by creating sessions,
flow control: shopping jsp (when user wants to add an item in the cart) --> item servlet (which is used to create session and synchronized it) --> cart servlet(which is used to add items in the arraylist and show them in the shopping.jsp's div tag + it also sets the total purchase amount in the session variable "totalpurchase")
now after that user wants to proceed to checkout, here i use the onclick event to check the minimumshopping amount must be less than the totalpurchase (totalpurchase which i had setted in the session),but my jsp page is unable to rechognise the updated value of the totalpurchase, yes, if i reload the page, it rechognises the new updated value of the totalpurchase? but i want it to rechognise the updated total purchase value, without reloading he jsp page..
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
1-I'd to be able to refresh my page. currently I've set it so it doesn't refresh so I can draw but I want to introduce timed refreshment for example after 30 seconds of drawing the page goes blank and starts again.
2- I'd like to introduce a maximum amount you can draw per each refreshment. E.g the page reloads every 30 seconds and each 30 seconds you have 100 ellipses you can draw, when it refreshes you have a new 100 ellipses
My code below...
PImage bg;
int cNum = 1; void setup() { // Images must be in the "data" directory to load correctly size(1200, 800); bg = loadImage("User_T_1.jpg");
As you can see above tabTwo has a separate fxml included within.
Now some of the tab content in tabTwo needs to be refreshed based on the actions performed in tabOne. But however initialize method of included tab action class is called only once for the first time when the fxml page loads. How the initialize method of tabActions.fxml can be forced to execute every time the tab loads?
I have a JSF page (called MainPage) with a commandButton: clicking on it, I open a modal panel with a <Rich:fileUpload> component, related to a listener in corresponding bean.
When I start to upload a file, page MainPage starts to refresh, but I would like to prevent this because it's not necessary.
I tried to "play" with <Rich:fileUpload> property values, but nothing seems to work and I don't know what to do anymore.
So the assignment is as follows. Develop a new class called BankAccount. A bank account has the owner's name and balance. Be sure to include a constructor that allows the client to supply the owner's name and initial balance. A bank account needs - accessors for the name and balance, mutators for making deposits and withdrawals. I have the following code :
import java.util.Scanner; public class BankAccount{ public static void main(String [] args){ Scanner reader = new Scanner(System.in); double name; double balance; double deposit; double withdrawl;
[Code] ....
I am having trouble with my if statements. I don't know how to link the number 1 & 2 keys to deposit and withdrawal actions. Plus I am supposed to have a while loop yet don't know how to implement this so that the while loop will ask the user if they would like to make another transaction after either depositing or withdrawing.
i have one html page ,inside html radio button and 3 textboxes and one submit button ->action->SampleServlet.java-> from here again come back to html page with checked radio buttton value and text box value. I dont want to click back button in this case, html page to servlet->here i have to call back to my html page with checked radio button and text box value .
I tried response.redirect(original.html)-->i cant able to display checked radio button and textbox value also tried requestdispatcher forward/include,html page comes newly from starting but i dont want it,i want to view in html page with checked radio button and text box value.
I want to validate the user session everyone when ever the request comes for any jsp page. I am able to validate the user in a filter for the first time. But i am confused what would happen when the request comes for other pages...how will i be able to get the same session from the server?
I have index.jsp in that page logout is available. while hitting the button . i want to invalidate all the session variable which i used. but it is not happening.
I have a question about how to check for a session as the user goes through different pages. I am using Java beans and EL to pass data from page to page but I cannot figure out how to check for a session on the pages without the use of a scriptlet with an if else statement in it.
I do not want the user to be able to access any pages unless they are logged in. With a scriptlet, I can create a statement that says if session exists show name else redirect to login page.
From what I have read and what some of the wonderful members here have told me, scriptlets are a big no no these days. So, how do I do these without the use of a scriptlet?
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 have to use the company's login resource, which returns a login page for authentication after a browser/user page request; after successfully authenticated, the session attributes are set in a (remote) valued object (VO) invoked via servlet; then, such values are set in my (local) POJO.
I want to display the current user session attribute (see xChave below) and save it in database. How can I persist http User session attributes through the structure below?
Abstract Controller (just the main code):
public abstract class AbstractController<T> { @Inject private AbstractFacade<T> ejbFacade; private Class<T> itemClass; private T selected; private Collection<T> items; //GETTERS AND SETTERS OMMITED public AbstractController(Class<T> itemClass) { this.itemClass = itemClass; }
The information is getting stored in the session and i am able to retrieve the same for single user. The trouble starts when 2 user logged in from different browser (for example chrome, IE) from the same machine. The 2nd logged in user, overwrite the session information of first user.
How to prevent this.
My environment: Windows 7 64 bit, IBM websphere server, Oracle 11g, JSP, Sevrlet.
how this is done using session.setMaxInactiveInterval(); at first, i did not set anything but it expires anyway.so i'm trying not to let the session expire.session.setMaxInactiveInterval(0) does not work.
I am pretty new to java and where I should start. What I am trying to do, is to retrieve live information from poker sites as I play, typically my hand and the pot size. Is this possible? I know poker sites probably are very secure, but I can see those things (my hand, and the pot) anyway, I just want it to happen automatically. What I am trying to do, is to create a program that retrieves the information, and then calculate the odds of me winning.
I am familiar with php, but I don't know Java. We need a program, that will be able to scrape large amount of title tags from large sites, fast. I've been trying Seo Spider by Screaming Frog, and Xenu's Link Sleuth, but these programs are not good enough. They hang up, they save all the data in RAM, I think, and after a relatively short period of scraping, they stop working, become unresponsive, and so on.
Somebody recommended me getting a custom made program in Java, which would be able to scrape title tags only, from large sites (I am talking 25 - 50 million pages or more). I was told that it would not have a graphic interface, or anything like that. Nothing like this is needed too, we just need to have title tags.
i am beginner in java and i am making an application in which i want to display menu for 3 different types of users. like when we login i want to check which type of user is this and which menu to show them. for ex. if there is a employee the menu bar has a dropdown which shows activities like fill nomination, see details etc. if it privileged user he is shown a diff menu and if its the admin the dropdown shows some different activities. i want to make it through simple jsp and servlet. i have a table in data base which has types of user predefined with an id how to display that menu according to a specific user.
