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...
I've made a login system with a username and a password. The password is visible and I wanna hide it, how do I do that? Here is my code (have used swing);
I am using form based, declarative security approach. And, when some user, on login form enters user credentials (username and password), he is being redirected to certain/secured jsp page.
Part of that page content is:Hello <%=request.getUserPrincipal().getName().toString()%> You are able to view this page because you are authorized user.You can see that this is implemented using JSP scriptlet. And this works. I would like to use JSTL instead of scriptlet.
So, instead of scriptlet, I put this JSTL code: <c:out value="${requestScope.userPrincipal.name}"/>, but not getting user's username with it. Basically, I don't clearly understand where and how are these objects/user credentials being stored with Form based JAAS.
I would like on JSP page to check if some user is already logged in. So, if there is logged user to display user's name (also with JSTL).Something like this:
<c:if test="${not empty sessionScope.userPrincipal}"> User <c:out value="${sessionScope.userPrincipal.name}" /> </c:if>
Here I tried with sessionScope but still not getting anything.
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.
I'm working on a simple site for my friend, and he asked me to link to his other site. I need to have the link to a specific search. For example, if I search for "Heathrow," I need to be able to link a button on the other site so that it can be clicked and directed to the search results on this page. Problem is that this is apparently all Java (which I know nothing of) and how to just copy a link to the results page.
i have a problem with navigating from a link in a primefaces tree menu to a specific page. The explanation is the following: I have a template with the following code :
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
[code]....
i had to put a "*" in the from-view-id tag to be able to navigate to the pages specified with the navigation cases. If i put /templates/leftMenu.xhtml insted of * then the navigation doesn't work and i get the error "WARNING: JSF1064: Unable to find or serve resource, /deleteDepartment-page.xhtml."

There are two designation named admin and student. I just need to work in coding to open specific page by email of person like done in facebook or any other mail account.

I want to implement a 'Keep me signed in' option in the login page of an application. I have noticed this option is present in the form of a checkbox on the login page of many websites but i don't know how it can be coded . When selected, a user is no longer asked for his username and password on subsequent sessions but he is automatically given access.
In My application I want to implement functionality to let user login from only one system at a time. I am searching for something that can Identify the system uniquely (Like IP address or Mac address ). I am using servlet and I don't know how to access Mac in servelt
So I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) { try { Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect /* conn.createStatement().execute("CREATE TABLE people (" + "id int(64) NOT NULL AUTO_INCREMENT," + "name varchar(255) NOT NULL," + "address varchar(255) NOT NULL," + "UNIQUE (id)," + "FULLTEXT(name, address))");

I downloaded Connector/J in the the binary .zip form and extracted it to my C: drive and put the .jar file into my java directories lib folder. I also added the directory of the .jar file into my CLASSPATH and I still get the exception.
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.
I am making a shopping cart app in JSP and servlets to bring it all together. Finally.
I have a registration servlet (c1), a registration form jsp (c2), a login jsp (c3). c1 checks if a username is in the database or not.
If the username is not there, then register the user and send them to c3. I want c3 to display a "registration successful" message if a user has just registered successfully and is coming from c1. ELSE, take the user back to c2 with a message which tells them to choose a different username or password etc.
How do I implement the logic of showing a message depending on where a user is coming from ? The servlets and jsps are ready and I only need to add this logic for a custom message. Of course, I could make a JSP for Registration Successful and one for Registration Failure. But, that seems to be unnecessary.
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 to implement a system where I have to do almost same processing on a jsp page. The slight differences on the present page is based on whether the current page came from page 1 or page 2. So how can I do this?
