JSF :: Enable / Disable SelectManyCheckbox Based On Radio Button Using Ajax
Feb 23, 2015
I'd like to disable/enable SelectManyCheckbox and the SelectOneMenu based on my selection. I have two radio buttons to be selected whether A or B. The SelectManyCheckbox and the SelectOneMenu should be disabled at the first run. When the user selects “A” the SelectManyCheckbox and the SelectOneMenu should be enabled and if the users selects “B”, the SelectManyCheckbox and the SelectOneMenu should be disabled and the items should be empty. I tried to use <f:ajax render="certificates"/>, but it doesn't work properly.
<h:selectOneRadio id="request" layout="pageDirection" value="#{user.hrRequest}" required="true" requiredMessage="Error: Select a Request Type">
<f:selectItem itemLabel=" Request A" itemValue="A"/>
<f:selectItem itemLabel="Request B” itemValue="B"/>
<f:ajax render="certificates"/>
[Code] ....

I am using Java Swing to create a GUI. I have some radio buttons on a JFrame that gets opened when the user makes a certain selection. I want to read a config file to have the radio buttons selected or deselected when the form is opened to indicate the current state of the radio button based on the saved config file.
How do I go about setting the radio button as selected (visibly selected) when I open up the JFrame?
I was trying to use RadioButton.setSelected(True); but this doesn't actually visibly select the radio button.

What would be the simplest way of creating a Dialog that can add TextField dynamically based on whether a radio button option from the dialog box is selected. I thought of JOptionPane.showMessageDialog and adding a JComponent though I would not be able to add a TextField on the fly and I would not be able to add ActionListeners. The dialog would initially contain some radio buttons, labels and textfields.

I am developing one form in jsf/primefaces. I have two inputText(inputMask) for e.g moble number and telephone number. I want to restrict the user to put only one of these two fields . That means if user starts putting value in mobile no. then telephone no. field should be disabled and if user starts putting value in telephone no. then mobile no. field should be disabled.
how should I do this.

I am learning Java but have a strong C# background. I am trying to figure out the syntax to do this in Java. In C# I would do the following to enable all text boxes in a panel
private void EnableAll() {
foreach (Control ctrl in Panel1.Controls) {
if (ctrl is Textbox)
((Textbox)ctrl.Enabled = true;
}
}
Is there something similar I can do in Java to do the same thing.

I'm working on a GUI application, I'm building it based on an example of a image provided and I am having an issue with my radio boxes, well the easiest way to explain will be if you look at the too attached images , the example im working from has the radio-boxes transparent they are the same color as the background image, my radio boxes seem to sit ontop of the background image with their default grey border, How can i make my radioboxes blend into the background like in the given example?
Im using Netbeans GUI toolkip to build this app, for the background image in the jpanel i just created a label and set the icon to the image i wanted.

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.
What should i do at client side???

I'm trying to make it to where each button is supposed to display the country's flag and a description. As of right now, I've hit a roadblock and haven't been able to get past it. As of right now, without the errors in the setDisplay method where setTitle and the other two are undefined for that type, I get each country's name listed as a radio button.
However, I haven't been able to get anything else to display.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Flags extends JFrame{
private String[] flagTitles= {"Canada", "China", "Denmark", "France", "Germany", "India", "Norway", "United Kingdom", "United States of America"};
private ImageIcon[] flagImage= {

Is it possible to enable & disable "jdk.certpath.disabledAlgorithms" property programmatically. I want to remove all disabled Algorithms for some time and later I will enable it.
Or is it possible to enable only for a particular place & not in a JVM level. I want that Algorithm need to be enabled for a piece of code, but I don't want it to the remaining part of the application.

I would like to access a third party websevice using a Java client that I generated with JAX-WS wsimport, based on the WSDL provided (I am using a Maven plugin).
For quite a while I was unable to retrieve a useful response, not in the Java client and also not in SoapUI, until I found out that I had to enable WS-A on the request. In SoapUI this now results in the expected response, but what must I do to also 'enable' WS-A in the Java client? Do I maybe have to alter the WSDL, or add a parameter to wsimport?
I found some documentation on WS-A online, but so far could not find an answer.

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">
<h2>Calibrations</h2>
<h:form id="tunerSelectionForm" style="color: #000000">
<h:commandLink>

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.
