I could get my session values in my jsp, now I want to compare the session value whether it matches the textbox, if it matches, it will redirect the user to another page else it will remain the same page.
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:
Can I access the session object even session has been expired? I need to check whether session is expired or not for each request.The session invalidation is set null the session object. What I concluded, session time out I can access session object but session invalidation I can not access session object. How can I find the session time out by using session object?
1) From War A, I login to the application and then fetch some users that is a rest call. I get the response back from rest in json form that ui consumes and display the data on page.
2) Now I click on the logout link from ui jsp. This logs out the session from Ui. I use <form data-dojo-type="dijit/form/Form" based logout.
3) I then go to the proxy (using burp) and manually request the rest call which I made in step no 1), the rest gives the response back with the same json object returned in step no 1) This shows that the logout action on step 2) is invalidated the session from War A (ui war) but the session or cookie based from WAR B (rest war) is not invalidated.
Expected outcome:After I Logout from War A(ui war), the session must also get invalidated from war B (rest war) and manually request from proxy should not get the same response object as received in step 1)
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..
Here is my code, basically I'll tell you what my program is suppose to do, I want to be able to leave the text box's empty if I like I want to skip 1 or more or all if I like skipping just basically means 0 but getting this error, it's forcing me to type in them all.

I need adding a textbox for users to input text onto my JFRame. Also how come the
frame.add(o);
is getting an error under the "add".
Main method class:
import javax.swing.JFrame; public class main { public static void main(String[] args) { JFrame frame = new JFrame(); bot o = new bot();
[Code] ......
Other class (this is where I want the textbox to be)
import javax.swing.JTextArea; import javax.swing.JTextField; public class bot { int x; int y; JTextField f = new JTextField(); JTextArea a = new JTextArea(30, 50); }
- The Instance Text box and SAVE button should be disabled. When the pop up appears. - The Instance Text BOX gets enabled only when any selection happenes in COMBO Box - The SAVE button gets enabled only when COMBO BOX and INSTANCE TEXT BOX is filled. - Let the CANCEL button be enabled always.
I have tried this example ([URL].../) with CarDao extending the BaseDao, it works like a charm.However, from the CarDao class, my NetBeans underlined the class name “CarDao” with the error message “A session bean must not extend another session bean.” But I can compile, deploy and run the application without any problem.
I have also heard that a session bean cannot extend another session bean, but why it works here?
I am using Java EE 6, NetBeans 8.0.1 and WebLogic 12c for this code testing.
Its supposed to notify the user if they have a palindrome, but keeps returning true even when I type, "hello".
import java.util.Scanner; public class PalinDrome { public static void main(String[] args) { String line; Scanner input = new Scanner(System.in); System.out.print("Please enter a word ");
I'm trying to get the input of two jcomboBoxes for example if jcombobox 1 option 1 and jcombox box 2 option 1 is selected result = x
Here is my code:
comboDest1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent event) { // // Get the source of the component, which is our combo box. // JComboBox comboDest1 = (JComboBox) event.getSource();
how can i compare date with following request the value date transction must be within the Active date(>= greater than or equal) and inactive date(<= less than) date range
public class Item{ private int myId; private int myInv; public Item(int id, int inv){ myId = id; myInv = inv;

I do not understand how to complete the compareTo() method and the equals() method. I understand that the compareTo() to should return 1 if the argument is smaller -1 if its bigger and 0 if they are the same, but I do not understand how it's possible to compare the current object with the object passed in as the parameter.
This is what I tried for the compareTo():
public int compareTo(Item other){ return this.compareTo(other); }
But my compiler tells me its a recursive call so I am not sure if I am doing this correctly.
Basically I am supposed to compare an object to another but I am not sure how to access the object that is not passed in as a parameter and compare it. Same goes for the equals(). This is what I tried for that (compiler also says its a recursive call):
public boolean equals(Item other){ return this.equals(other); }
public class Circle extends GeometricObject implements Comparable<Circle> { private int radius; public Circle(int newRadius) { radius=newRadius;

When I run the driver class it tells me that all tests have passed(as it should be) except for Test 0. I have tried to play around with the code, but I cant figure it out and it is driving me crazy because in my head my code makes sense.
I have a ArrayList of objects of class called HockeyPlayer (ArrayList<HockeyPlayer>). A HockeyPlayer has a String name and int number of goals.
This is my current work for comparing each object in the list to every other and printing them to screen:
Iterator<HockeyPlayer> it = hockeyPlayersList.iterator(); while (it.hasNext()) { HockeyPlayer singleHockeyPlayer = it.next(); //the first one encountered // HockeyPlayer nextHockeyPlayer = it.next(); //the next one encountered
[Code]...
This of course produces some duplication in the print-out: These are the equal hockey players: Who Ever wears jersey. This type of employee is paid: true. This employee has post-secondary education: false. This employee's work is to play. This hockey player has scored 0 goals.
Jason Harrison wears jersey. This type of employee is paid: true. This employee has post-secondary education: false. This employee's work is to play. This hockey player has scored 0 goals.
