I am getting the problem as If call the action class through the ajax, my property values not setting to the formbean class, How can I use the formbean to set the all my property values and getting in action class.
View RepliesI'm not a java developer, i'm a tester. I am currently testing a java swing application and to do that I have to automate how its used. IE I have to write code which will press buttons for me rather than depending on an end user to do this. I have managed to reverse engineer the entire application (hooray for me), however I am struggling to work out how to invoke methods that would typically be kicked off by a user pressing a button. how to I can call actionPerformed(ActionEvent ae) method which sits in the ATMMainPanel class?
I will be calling it from inside another method which is the equivalent of the main() method.
Java Code:
public class ATMMainPanel extends JPanel implements ActionListener {
[declarations here]
//here - User is pressing the Enter button after putting in pin.
public void actionPerformed(ActionEvent ae) {
[code performed when button is pressed]
} mh_sh_highlight_all('java');
This is my first servlet program. I wanted to try a web application where "register" user module will be in servlet program.I can access my index.jsp but when I enter values and click submit.
I get "There is no Action mapped for namespace [/] and action name [RegisterUserServlet] associated with context path [/TrainingApplication]. - [unknown location]".
Here's my index.jsp file:

The following code is located in my main class called InjectionFix. I have another class where I need to call or initiate the string in the code below. How can I achieve this. I tried to create an Object of the class but I cant do this because my other class doesnt contain a main method.How can I get the other class to initiate the code below which is loacted in my main class.
public static String escapeDN(String name) {

I am trying to make a JTree. I have used this guide :[URL]
Now when I call my Class with
TreeMainMenu tree = new TreeMainMenu();
JScrollPane MainMenu = new JScrollPane(tree);
I get only the default JTree..
I need to understand how I should build my code to call the class as JTree.
This is my code:
public class TreeMainMenu extends JTree {
private DefaultMutableTreeNode top = new DefaultMutableTreeNode("TOP");
JTree tree;
public JTree TreeMainMenu() {
APNode();
tree = new JTree(top);
tree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);

I have wrote the necessary program for the class which was : Modify the customer class to include changeStreet(), changeState(), and changeZip methods. Modify the account class to include a changeAddress() method that has street city and zip parameters. Modify the Bank application to test the changeAddress method.
The problem arose when I went to test it. For some reason when it asks "Would you like to modify your account information? (y/n)" it will not allow the user to input anything and thus test the class. Here is my code
Class Customer
import java.util.*;
import java.io.*;
public class Customer {
private String firstName, lastName, street, city,state, zip;

I am newbie in java and little bit known to apex. I write an java code and compile it to class file. Now i want to call that class file from an push of button on apex. When button is pushed i need some arguments to be password to java class files . For arguments i need to take the item value from the apex page.
But i stuck on how to call that java class file from apex. On command prompt when i ran java class file, its working.
For reference I am programming Java in BlueJ. I am fairly new to the language and I am having trouble with sorting.
I am trying to call / test all of the 5 sorting methods (at the same time) in the main class. To be specific, the sorted list has to technically outputted 5 times.
I figured out how to call / test Quicksort:
Sorting.quickSort(friends, 0, friends.length-1);
But the others are not working correctly. Specifically these:
Sorting.mergeSort(friends, 0, friends.length-1);
Sorting.PbubbleSort(friends, 0, friends.length-1);
Sorting.PinsertionSort(friends, 0, friends.length-1);
Sorting.selectionSort(friends, 0, friends.length-1);
For reference, this is the output when it is not sorted:
Smith, John 610-555-7384
Barnes, Sarah215-555-3827
Riley, Mark 733-555-2969
Getz, Laura 663-555-3984
Smith, Larry464-555-3489
Phelps, Frank322-555-2284
Grant, Marsha243-555-2837
This is the output when it is sorted:
Barnes, Sarah215-555-3827
Getz, Laura 663-555-3984
Grant, Marsha243-555-2837
Phelps, Frank322-555-2284
Riley, Mark 733-555-2969
Smith, John 610-555-7384
Smith, Larry464-555-3489
This is the class Sorting, which I should note is all correct:
public class Sorting{
/**
* Swaps to elements in an array. Used by various sorting algorithms.
*
* @param data the array in which the elements are swapped
* @param index1 the index of the first element to be swapped
* @param index2 the index of the second element to be swapped
*/
private static <T extends Comparable<? super T>> void swap(T[] data,
int index1, int index2){
T temp = data[index1];
data[index1] = data[index2];
[Code]...
This is the Main class in which I am supposed to call the sorting methods, SortPhoneList:
public class SortPhoneList{
/**
* Creates an array of Contact objects, sorts them, then prints
* them.
*/
public static void main (String[] args){
Contact[] friends = new Contact[7];
friends[0] = new Contact ("John", "Smith", "610-555-7384");
friends[1] = new Contact ("Sarah", "Barnes", "215-555-3827");

I have two images. I want to be able to click them and kick off a call to a listener in Java to change a value in the bean. I also want the view to update my dropdown (labeled "menuModel") to either be rendered or not, depending on which image I click. Alternatively, I would be fine with the dropdown simply being disabled and enabled for the same criteria.
So far, the listener kicks off fine, and the value gets updated correctly in the bean. However, the view never gets updated. I have tried this a hundred different ways, but nothing seems to work. If I hit refresh on my browser, the view updates. But I want it to do it automatically.
I am using standard JSF 2.1.
<div style="font-family: Verdana; font-size: 10pt; color: #FFFFFF">

I have a requirement where a form is present with first name, last name, file upload etc. File upload is done through ajax call and then the form is submitted to a servlet. I want to know whether the file has been uploaded or not in the servlet which is called after i click on the form submit button. So is there any way i can read the response of the ajax call in the servlet ?
here is the ajax call below
$.ajaxFileUpload
(
{
url:_action,
[Code]...
public Unit(String code, String name)
{
enrolStudent(student);
this.unitCode = code;
this.unitName = name;
}
public void enrolStudent(Student newStudent){
students = new ArrayList<Student>();
newStudent = new Student(24662496, "Kingsley", " Iwunze");
students.add(newStudent);
}
how can I call this enrolStudent() method on this Unit constructor in another class when I create a new Unit. all I need is to enroll students in units when units are created. below is my create unit method.
public void createUnits( ){
units = new ArrayList<Unit>();
units.add(new Unit("FIT2034", "Java Programming 2"));
units.add(new Unit("FIT2024", "Software Engineering"));
units.add(new Unit("MAT1830","Discrete Maths"));
unit.enrolStudent(new Student(25486321, "Julia", "Garcia"));
unit.enrolStudent(new Student(44589736, "James", "Olivia"));
unit.enrolStudent(new Student(47852103, "Lucky", "Thyriod"));

I'm having problems with using the h:inputFile tag with JSF 2.2 and Glassfish 4.0 on Eclipse. The file uploads work when the enctype is set to "multipart/form-data" in the h:form tag, but AJAX will not work. When I leave out the encType (defaults to "application/x-www-form-urlencoded") AJAX works but the uploads do not work, and in fact Glassfish crashes and generates the message:
The request content-type is not a multipart/form-data
Likewise I'm having the same problems with the PrimeFaces file upload tag p:fileUpload. In a JSF 2.0 it works correctly, but with JSF 2.2 it's giving the same problems and generates the message above.
When I start up Eclipse it tells me that Mojarra 2.2.0 is installed. Is this the source of the problem, and if so, how do I install a later version of Mojarra?
I'm required to implement audit logging of all action requests. The logging should contain the action name and request parameters. I have implemented the logging in a phase listener (PhaseId.INVOKE_APPLICATION).
I'm having trouble figuring out how to get the action name from ajax requests. More specific when the form command button does not contain an action attribute:
<h:form>
<h:commandButton value="#{text.update }">
<f:ajax execute="@form" render="@form" listener="#{backing.update}" />
</h:commandButton>
</h:form>
Calling the UICommand object (which represents the pressed button) getActionExpression method returns NULL.
When I look at all the showcase from various "faces" components, I see lots of Javascript, powered by jQuery, etc.
Where's the Java part of things? Are JSF component simply JavaScript Ajax widgets?
What makes a JSF component different than say a regular old webpage using jQuery to do something in Ajax to a PHP back end script?
I have a page which lists items using a ui:repeat. The repeat is surrounded by my h:form tag.
Now I have made it so that when click an item, then I load some item details - render them in their own xhtml file and inject the result into the dom tree.
This is causing some problems.
* My injected content has commandButtons and commandLinks which do not work because I don't have a form in my injected page - since this would cause nested forms :-(
* tried to replace commandButtons and commandLinks and instead create unique url's that I can call to get my work done - but how to I then re-render a panelGroup on then page? tried using jsf.ajax.request but I'm not able to get part of the page (a shoppingcart) to update
Basic outline
<h:form>
<table>
<ui:repeat ...>
<tr><td onclick="...">Click here to load item details</td></tr><tr><td id="itemDetailPlaceholder"></td></tr>
</ui:repeat>
</table>
</h:form>

I am new to JSF and I am working on handling session timeout for a JSF application. I am trying to get the code to work for ajax calls and not able to achieve that so far. I have tried two approaches:
Approach 1: SessionListener (for cleanup work) and SessionFilter (for filtering every request and checking if session timed out)
My Code snippet of doFilter() of SessionFilter:
if ((request instanceof HttpServletRequest)
&& (response instanceof HttpServletResponse)) {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
// is session expire control required for this request? (not required for home page or timeout page or JSF resources)
if (isSessionControlRequired(httpServletRequest)) {
[Code] .....
Both these approaches work for non-ajax POST calls but not for ajax calls. When I run my app in debug mode, I can step through all the statements for ajax calls also, which gives me an idea that the control does come to my code, executes it but for some reason, nothing happens on the UI.
I have been trying to redirect user to a timeout page but the ideal thing would be to display a JSF dialog and upon hitting 'OK' take user to Home Screen (My app does not have a login screen.) I have a basic questions also, is view expiring exactly same as session timeout?
I have one row editable datatable.I have implemented email validation to one of the column where error message must display on blur of email field.This is working fine.I have a dialog with form to be displayed in the same page. Validation is implemented to this form also with on blur event. The dialog validation message gets displayed on blur but along with that the main form also displays the same validation message. This should not happen.
JSF page
<h:form id="lpcForm">
<div id="content">
<p:commandLink id="cmdLinkDelete" value="Delete"
style="font-size:15px;padding-left:15px;" ajax="true"
action="#{lpcBean.deleteRecords}" update=":lpcForm:lpcDataTable" />
[Code] ....
The message with id lpcErrMsg is the one that i am displaying on blur in the main page when email format is wrong.And this message gets displayed with dialog field validation also although i have never referred to this id to be rendered in the dialog.
The message with id lpcDlgMsg is the message that i am displaying inside the dialog with widgetvar dlg on blur.As of now i have implemented blur event validation for the first required field in the dialog.

The SelectManyCheckbox and the SelectOneMenu should be disabled at the first run.

I am making an MVC program and I am not allowed to put the action listeners in the view class. I was able to get one button working fine but since I am unable to reference them I cannot give them both individual responses.
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class Controller {
HobbyList model;
ListView view;
[code]....
My output is all over the place. I cancelled out the borderlayouts beneath each panel I created and it completely changed the output, and I'm not sure why. The first photo below, shows what it looked like with the layouts and the second shows the output without. I still don't understand why I don't see the digits 1-9.
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionListener;
public class Atm extends JFrame {
Atm(){
super("ATM");
//Create Panels For ATM
JPanel buttonPanel1 = new JPanel(); //To Contain Digits 1-9
[Code] ....
Why would setting the layout beneath each object change the layout so much? I stayed consistent in my use of BLayout and GLayout in the program.
