JSF :: Possible To Concatenate String In Selectonechoice Component?
Mar 7, 2014
<tr:selectOneChoice value="#{bean.aValue}" required="true">
<f:selectItem itemLabel="Option1" itemValue="1"/>
<f:selectItem itemLabel="Option1" itemValue="2"/>
<f:selectItem itemLabel="Option1" itemValue="3"/>
</tr:selectOneChoice>
Supposed that selectItem loads a list from the database.
But I want to display "Option1 - testing" without modifying database value.
testing is a string datatype in the backing bean

I have a JPanel that's using a simple GridBagLayout.
JPanel panel = new JPanel();
GridBagLayout qPanelLayout = new GridBagLayout();
qPanelLayout.columnWidths = new int[] { 0 };
qPanelLayout.rowHeights = new int[] { 0 };
qPanelLayout.columnWeights = new double[] { Double.MIN_VALUE };
qPanelLayout.rowWeights = new double[] { 0.0 };
panel.setLayout(qPanelLayout);
componentCount = 0;
Based on user input I am adding sub-panels to the panel. These sub-panels may vary in height. They take up the full width of the Panel.
public void add(Component comp) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.insets = new Insets(2,2,2,2);
gbc.gridx = 0;
gbc.gridy = componentCount++;
panel.add(comp, gbc_questionPane1);
}
The odd behaviour I'm seeing is that if the height of the new sub-panel I'm adding is less than the height of the largest sub-panel currently displayed then the main panel does not repaint. If its height is equal or greater then the Panel does repaint, and any sub-panels that were added but not visible before are now painted. What have I missed?

Write a program that declares and concatenates various strings. Declare strings for your first name, middle initial and last name, along with one for your address, city, state and zip. Make an additional string called firstLine, which will be a concatenation of first name, space, middle initial, period, space, and last name. Assign each of these strings a value, and then print the information in the following format:
First Line (First name Middle initial (period) Last name)
Address
City, State
Zip
For example:
John Q. Public
1234 Any Street
Cleveland, Ohio
44101
Now reassign the strings in the same program (Do not create a separately compiled program!) and repeat the printout for different information. When you are finished, your program will print out two groups as above.
The information should be placed into the seven separate strings, then a first line should be formed by concatenating first name, space, middle initial, period, space, and last name. The city and state line should be formed by printing city followed by a comma, a space, then the state (NOT by concatenation). This is so you can see different ways of making lines."
And this is what I have so far:

Ok so what I a String array of binary numbers
private String[] encodedNumbers = {"0000", "0001", "0010", "0011","0100", "0101", "0110","0111","1000","1001","1010","1011","1100","1101"};
and what I want to do is simply run through a loop (Which I already made ) that will randomly just put this strings together.
So if the loop runs once it will return something similar to
00001011001101000110
The thing is that I don't want to return such a number as an String, I want it to be returned as a long.This was one of my recent attempts
/* Contains the genes or possible solutions to the problem
*/
public class Genes
{
/* Each element is a binary number that corresponds to index number they have been assigned to, these are the possible genes
* The last 4 elements in the array represent + - * / correspondingly
*/
private String[] encodedNumbers = {"0000", "0001", "0010", "0011","0100", "0101", "0110","0111","1000","1001","1010","1011","1100","1101"};
[code]...
What can I do ? I want them the values returned to be of the long data type, but I don't want the binary numbers to be added together. I just simply want them to be placed one next to each other at random patterns

I cannot add the component from this class:
Java Code:
package TestVersion;
import java.awt.Color;
import java.awt.Graphics;
public class matWood {
private int woodX = 250;
private int woodY = 100;
[Code] ....
The error is at Java Code:
frame.add(matWood); mh_sh_highlight_all('java');
And this is what it says:
The method add(Component) in the type Container is not applicable for the arguments (matWood)

In a java application project called mycomposites, i created xhtml with a composite component interface and implementation in mycomposites/ src/ main/resources/testcomponents/myComponent.xhtml...Then I created a new project testmycomposites added mycomposites as dependency. Here is the source of an xhtml that should use myComponent:
<?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:h="http://java.sun.com/jsf/html"
[code]...
However running project, I get error:<tp:myComponent> Tag Library supports namespace: http://java.sun.com/jsf/composite/testcomponents, but no tag was defined for name: myComponent
If i put the same custom component in resources/testcomponents folder of the same project everything works fine.I can't find any example in wich custom composite components are located in a dependency.

I have created a text file that contains a small list of toy names and prices, like:
Barbie, 12.95
Lego, 15.99
Hot Wheels, 5.00
Power Rangers, 6.49
And what I would like is my application to read the contents of the file and store the toy names in a list component. And then I want to be able to select a toy name from the list and add it to a shopping cart that is a list component as well. I want to the application to have menu items and buttons to allow me to remove items from the shopping cart, clear the shopping cart of all selections, and check out.
When I check out, the application should calculate and display the subtotal of all the toy names in the shopping cart, the sales tax (which can just be 8 percent of the subtotal), and the total.
How to create this simple application example I've just made up, and I'm going to add and use this example to create a bigger application myself.

I have an issue about loading images from css using a composite component. The folder structure is:
resources
resources -> css -> componentname
resources -> images - > componentname
resources -> WEB-INF
If i write in the css something like
border-image: url(resources/images/componentname/image.png) !important;
or
border-image: url(images/componentname/image.png) !important;
i have a 404 error and i can't see the image.
I able to load the image only if i write path with context-root:
border-image: url(/<CONTEXTROOT>/resources/images/componentname/image.png) !important;
but i can't write explicit context root in css files!!
So, i tried to use resource EL variable:
border-image: url(#{resource[image/componentname/image.png]}) !important;
but this last way render
border-image: url("/<CONTEXTROOT>/javax.faces.resource/images/componentname/image.png.faces.faces") !important;
and i not able to replicate the right way written above.
The project is developed with RSA9 and WebSphere Portal 8, but if i try to execute it in NetBeans (no portal) it run correctly!

I have to create a new custom tag "imageLabeable" as a div contains a GraphicImage and an OutputLabel (primefaces).
Since I want to make it reusable as much as possible, I tried to write, in cc:interface section, all GraphicImage attributes (id, value, binding etc) and some new (GraphicImage is the main component among the two). But after that I have must associate GraphicImage attributes with the attributes created in cc:interface:
<cc:interface componentType="imageLabeable">
<cc:attribute name="value" />
<cc:attribute name="alt" />
<cc:attribute name="width" />
<cc:attribute name="height" />
[Code] .....
As you can see, if I have a lot of attributes I have to write a lot of association. Furthermore, if I see html rendered code with Firebug or similar, I see all of these associations.
Can I inherit these attributes automatically? Or associate it in easier way?

I heard one of the senior architects in my company before tell me to treat component distribution as a last resort. So if EJB were created for such, why were they created if component distribution is not encouraged anyway? just got confused here. I remembered this because I am currently in a dilemma of whether to redesign an app having performance problems. Options are either create EJBs for it and put them in another server or purchase another server to have a load balanced setup.

I am using the Javafx 8 Date Picker. Its works fine. I have defined a stylesheet for my application and in that style sheet i have a style for Button. I apply this style to the every scene. Now my question is: When I use the datepicker and I click on the calendar icon, the datepicker popup appears and the left and right arrows adjacent to month and year fields in the seems to pick the style of the button class from style sheet defined in my application., Is there a way to avert this and tell datepicker to use default styles and not the styles defined my application.
I tried removing the style at runtime from the scene, but of no use.

Can I add actionListener to a button component without creating a reference to it? Look at my code below:
public void init() {
setBackground(Color.red);
//Create the layout
setLayout(new BorderLayout(20, 5));
//Add buttons
add("North", new Button("Red"));
add("South", new Button("Yellow"));
add("East", new Button("Cyan"));
add("West", new Button("Magenta"));
add("Center", new Button("White"));
}
Or should I just do the usual instance.addActionListener(this) like myButton.addActionListener(this)?

I am trying to use the JList to display a list of students. Now, each student has a first name, last name and course taken. each courses taken by the student has its' own name, level and idNumber. For now, I am just trying to create my own custom JList model for the students. I have the custom model as well as the button event calling it. Unfortunately, when I click the button to display the student info added, the component is NOT fired up!..
I am not sure what I have done wrong regarding creating the component because I can display the information on the console and the list contains everything I have added but just to display it on the component is NOT working. I have broken the codes into sub classes, you can add the classes to the same package or create sub packages to insert individual classes.
The student class
public class Student {
private String studentName;
private String studentID ;
public String getStudentName(){
return studentName;

I have a problem to display a popup with the information of the registered event. I would like the user to hover over a particular event exhibited only the description of the event without having to click on the event to view information. I would like to make an ajax request to that was displayed a popup.
But do not know how to implement jquery and javascript. Well, I am new to programming. My code that generates the schedule is as follows:
<p: schedule value = "#{bean.datamodel}" widgetVar = "sheldule" locale = "en"
rightHeaderTemplate = "prev, next" leftHeaderTemplate = "today" centerTemplate = "month"
id = "events"
tooltip = "true">
<p:ajax event="dateSelect" listener="#{bean.onDateSelect}" update="eventsNew" oncomplete="eventDialog.show();"/>
<p:ajax event="eventSelect" listener="#{bean.onEventSelect}" update="eventsNew" oncomplete="eventDialog.show()"/>
</ p: schedule>
In my Bean have methods that make the selection of date and event. Have I configured the option of setEditable to true. Ajax function, jquery or javascript to show the popup containing only observation and event date. And looked at the documentation of primefaces and not found any implementation to solve my problem.

I don't know if this is possible before JSF2.0, but I got a requirement that basically says that I need to be able to add focus to a certain element on the page using a custom JSF 1.2 component.
Currently, I do this with a short jQuery method where you add a class called 'focus' to the inputText component you want focus on. This works perfectly, but I need to also foresee a nested component inside h:inputText to do this.
Example:
<h:inputText id="myFirstTextField" value="#{bean.someText}">
<o:focus/>
</h:inputText>
I had thought about just putting an element with a certain class and using a jQuery selector to get its parent, but then I realized the html input tag does not allow subtags and that couldn't work, so I need something that won't be rendered but will do the job.
Migrating is evidently not an option.
I'm using Seam 2.1.2 and richfaces 3.3.4

I have a big issue to render this html page with the webview component :
<html><head lang="en"> <meta charset="UTF-8"> <title>Pb Rotate</title> <style type="text/css"> #myDivRotate {
color: purple; background-color: #d8da3d; height: 200px; width: 300px; margin-top: 20px; margin-left:20px; -webkit-transform:perspective(400px) rotateX(30deg); -webkit-backface-visibility: visible; }
</style></head><body> <div id="myDivRotate"> Coucou
</div></body></html>
The problem is from "perspective" in -webkit-transform. Without it's ok. But with this one, the result is different from a standard browser like chrome or safari.
