JSF :: Dynamically Adding Components - Object Doesn't Have Such A Property That Is Readable
Jan 12, 2011
In a project I'm ivolved in I have to dynamically add some components. All was going well until I had to generate data tables dynamically. I'm iterating a list of "SomeObject" and when I try to access a property of that object Glassfish tells me that object doesn't have such a property that is readable. I have getters for those properties and SomeObject implements Serializable as well. I used BalusC resources but I'm having no luck.

I'd like the code that would return an object's human readable name.ie. myObject.getObjectsName();Which would return the name of the object That is, the name of the object that I use as I code.In the code below, I'm trying to find the correct code to return the string,btnTTT_01..The results of the testing follow.
public static void main(String []args) {
tictactoe game ;
game = new tictactoe();
game.setVisible(true);
System.out.println ("main") ;
System.out.println ( "game.getName() is: " + game.getName() ) ;
System.out.println ( " " );
[code].....

I wish to display a progress bar during a lengthy file translation process. When I created a ProgressBar class to do this and tested it with a short test program, it seemed to work fine. But when I add my ProgressBar class to a package containing various other classes, put that package in a jar file, and then execute the class using the progress bar from a menu in my main program, the frame of the progress bar shows up with the appropriate caption but the JLabel, JProgressBar, and JButton are not displayed. I have gone over my code numerous times and checked that the ProgressBar class constructor is getting the proper arguments.
// package gov.nasa.jpl.ephemeris;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/**
* Progress bar with message text above the bar and a Cancel button below it
*/
public class ProgressBar extends JFrame {
private boolean _cancelled = false;
private JProgressBar _progressBar = null;
[Code] ....
I have also been wondering whether I need a separate instance of the border for each panel, or whether I can just create one instance and use it for all three panels.

I'm having trouble conceptualizing something. I will post the code, it's works exactly as it should. I create an array and Hash Map to display periodic table of elements information after allowing the user to search by element name or symbol. I want the user to also be able to add elements to the periodic table. I can't really conceptualize how I am going to do that with an array I've already created.
Here's code:
//Create element objects.
//Here is where I create my "elements" array, and where I could like to prompt the user to add elements, if desicred.
Element[] elements = {new Element("Hydrogen", 1, "H", 1.008,1,1), new Element("Lithium",3, "Li", 6.94,2,1)}; //
//Maybe it seems if I prompt the user here to add new element names, symbols, weights, etc, I would be overwriting

I have got the code listed below:
class Address {
String name;
String street;
String city;
String state;
String code;
Address (String n,String s, String c, String st, String cd){
[code]....
Using JDK7 is there a way to get an object that has got a specific property from the collection? For instance, I might want to seek if there is an Address containg "Tim Carlton" in the ArrayList.

I have a Die class that extends Label. It has a SimpleIntegerProperty called faceValue. In another class I have an ObservableArrayList of Die called dice and a FilteredList of all the die in dice with a faceValue of 2. The Problem is that when I update the faceValue (ie. roll()) the filteredlist doesn't update with the Die that faceValue=2. I believe the reason is that the filteredlist updates when a ListChangeListener is fired. If i add, subtract elements from dice I don't have a problem but how do I make it so that updating the faceValue on the die counts as a ListChange, or is there even a way to do that.

I need to be able to call this method and it should take the object and, add it to my list of items, but I am having trouble getting it to work. I know the numbers and stuff aren't correct eventually it will add one to the array length when i call add item, but I am just trying to go one step at a time
//creates new MediaItem object and add it to items[]
void addNewItem(String title){
MediaItem object = new MediaItem(title);
MediaItem[] items = new MediaItem[1];
items[0] = ("object.getTitle()");
numberOfItems = numberOfItems + 1;
System.out.println(items[0]);

I am trying to build a method that takes an array of object and adds a new object of that type to the end of it . ONLY ALLOWED TO USE ARRAY , NO ARRAYLISTS VECTORS ECT . i realize that if the array is full you can use the java copy array method to make a new array and double its size until a certain point . The MAX AMOUNT OF OBJECTS is a constant that is 100 but for some reason even when executing my code i keep getting null pointer exceptions or index out of bounds errors , i have written this method many times now with out any success.
My question is how do I write a method that adds an object to the end of an array and if there are no spots left copies the current array into a new array and extend the size
private Animal [] objects;
final int MAX_ANIMALS = 100;
public AnimalObject()
{
objects = new AnimalObject[MAX_ANIMALS];
}
public AnimalObject(Animal[]a)

We are doing a Timeline project, So this is what i want to do:
Pressing a "New Event" button opens the New event window where you are supposed to write input in three fields, name, date, and information. There is also a button "Create" that when i press that button, i want to take all the input from the fields and save/send it to our database, and go back to the timeline GUI. With this, i want a new event object to be created(in this case i have done several shapes in a group) so basically a new group i want to be added. All the information is suppose to be taken from the database right after i create it.
I'm pretty stuck on how i should solve this, for the moment have a group called event that i add on the canvas. First thing that pops up in my head is a void method that draws the event, or maybe a temporary array.. P
package application;
import controllers.CreateEventController;
import application.EventPop;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Cursor;

I have a program I am creating in Eclipse. In my JFrame window, I am adding a JList object that I want to load with an EnumMap that I have created in a separate 'enum' class.
In my JFrame, I have a method called 'loadJList()' in which I want to iterate through the EnumMap and load the keys & values.
Here's what I've tried
In my EnumMap class, I've done the following ...
Java Code:
public enum MyEnumMap {
.....//created map values & keys, getter() and setter()
public Enum<MyEnumMap> getEnum() {
return this;
}
} mh_sh_highlight_all('java');
I imported my EnumMap program in my JFrame program and tried something like ...
Java Code:
public void loadJList() {
for(Enum<?> e: myEnumMap.values()) {
list.add ....
}
} mh_sh_highlight_all('java');
Which does not work. I've scoured the internet a bit but sources on EnumMap are limited, at least ones I can understand (first time trying to use this).
I also need to elaborate on the key of the EnumMap (they are cities, I'd like to add the state or country). For example
LASVEGAS, 749.99
I would want displayed as
Las Vegas, Nevada .... 749.99
My ultimate goal here is to access my EnumMap in my JFrame program to dynamically load a JList object.

I have to read in a file that that has Student, Employee, Faculty....such as name, last name, salary...etc
Example of a file input
Java Code: Student, John, Doe, [email]johnDoe[At]yahoo.com[/email], 123,Wonderland Ave, 21323,TX

[code]...
There is more code, but it's repetitive. Now, I keep getting an error. Array of bounds. I believe i get the error because the phone number. The phone number is on the next line..I created a different arraylist for phonenumber, but I dont know how to match it with the correct person, student, employee...etc.

Will it make any difference if I put the last line of code inside the useBean tag ?
<jsp:useBean id="person" class="foo.Person" scope="page" >
<jsp:setProperty name="person" property="name" value="Fred" />
</jsp:useBean>
<jsp:getProperty name="person" property="name" />
It gives me the same output though....

I have 4 variables: longitude, latitude, accuracy and distance. I need to store these variables in two different servers, one for private data and the other for public data, in the cloud. Before sending those data to the server, filtering is takes place as private and public variables so that the private and public data will be send to the respective urls specified with.
public class LocationTracker{
private longitude;
private latitude;
private accuracy;
private distance;
// other tasks
}
public class Filter{
[Code]...
My intention is to assign those variables the characteristic/properties, public or private, thus, I can easily identify them anywhere in the code whether they are public or private and store them to the respective urls. If the private data attempt to be send to the public url, the rejection should be made. So, How do I do that?

I am trying to find a way to make a URL that is used during a background AJAX call to log a user out more flexible. Currently, I have it as a static value, as below:
var logoutURLTest = "https://test.myorg.com/cas/logout";
...AJAX stuff that uses the logoutURLTtest variable...
However, if that URL was to change for any reason, I would have to modify one or more JSPs if they were affected, instead of just changing it at a single point in the Spring environment context. It would be more desirable to expose the value using a property placeholder; however, the Spring documentation isn't exactly clear on whether this is possible.

In the SceneBuilder properties panels (part of Inspector pane) there are nice subheaders - separated by horizontal lines with a decent gradient in the background. I've tried to investigate the SceneBuilder source code at [URL] …, but I haven't found the proper file where this subheader is defined and styled.
I'd like to use similar subheaders in my app and why to reinvent the wheel...
