View RepliesActually I use MyEclise to develop and deploy a enterprise project(EAR file). I use Java Build Path to add some other projects and link sources, and added several jar files (as external jar and user library) to my project. (I used J2EE technology and there are some default jar of course )
By myeclise deploying manager I deployed my project on weblogic base_domain and then by weblogic console I deploy it on weblogic. All is set and there is no problem in all steps.
Now I wanna to create EAR file manually, first I created WAR file which included some jsf files and web-inf directory contains classes, lib directories and some important file like web.xml , facec-config.xml and etc.
In classes folder I have .class files which build correctly from .java files, and on lib directory**I copied all jar file from web-inf/lib directory** which created automatically by myeclipse deploying manager on weblogic base domain folder.
I added this War file into EAR file along APP-INF directory which contains all jar files from APP-INF/lib directory on weblogic base domain folder and META-INF directory what contains application.xml file.
When I deploy this ear file on weblogic there is so many error and problems. What is the correct way to create that EAR file.
I installed Windowsbuilder in Eclipse as described in this video:URL....
To get starated I now want to create a simple JFrame application that works in the following way. On the opening screen I want to present 4 buttons. Based on the selection I want the JFrame to change layout and components so that the same JFrame behind the scenes contains 5 layouts but only one visible at any time. What is the best way to accomplish this? Or should I do this in another way using multiple JFrames or similar?

View Replies View RelatedI am writing a Java Swing GUI application on my pc. I have to give this application to my cousin with another pc, where he is not aware of programming. then how can he execute that application? are there any ways of skipping the "javac" and "java" procedures while executing the app on his computer?
I am using win7 x86 and same at my cousin's place. I am also using eclipse-kepler sr1 ide for app development.
Are there any easy ways of automating this "javac" and "java" process(compilation and execution)? something like...scripting?

View Replies View RelatedI need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :
* import javax.swing . ;
{ public class SwingWebPage
public static void main ( String args [ ] ) throws Exception {
JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ;
website.setEditable ( false) ;
[code]...
If you test , you'll see that the page is displayed in the JFrame is horrible.
I lately started using "advanced" Swing-Components, like JTabbedPane and JComboBox, but I dont get the ComboBox working/This is the code I use:
public class PreferencesPanel extends JPanel
{
public PreferencesPanel (MapEditWindow window)
{
super ();
setLayout (new FlowLayout ());
String[] resolutions =
{
"1024x768", "1280x800"
[code]...
The TabbedPane is placed in another JPanel, which is placed in an Fullscreen-Window.
Now, the problem is, that when I start the application and open the "Preferences"-Tab, everything seems normal, I can see the ComboBox and the first entry is selected. But when I click it, instead of opening and offering me more choices, the program crashes and my screen turns black (I'm using OS X, on Windows it would possibly turn white, but I didnt test this out).
I'm developing a java swing application in which i need to show the map of some area and allow user to put markers on it. I've goggled a lot on the topic but unfortunately i haven't got any how i can do it.
I came across some ideas like displaying a web browser in swing just like JXBrowser (i can't afford JXBrowser). And I'm also not sure if this way will allow me adding markers.

I have to create a Swing application for which i haved a set of requirements as,
1. there will be two JPanels ,left and right, on the main JFrame , left frame would contain a JTextField and a submit JButton ,user can enter values 1,2,3 ,in the JTextField and presses the JButton
a. if user enters 1, a JTextField will be shown on right JPanel
b. if user enters 2, a JTextField and a JRadioButton will be shown on right JPanel
c. if user enters 3, a JTextField and a JComboBox will be shown on right JPanel
So I have done that but when my boss sees the code behind this application he told me to make it more extensible i.e. if there is going to be an additional requirement for values 4 or 5 or 6 and so on , then i have to make minimal changes in my code or no change in my code and it should work . how this can be done ? is it possible make such software design ?
public class DesktopApp extends JFrame {
private static final long serialVersionUID = 1L;

private JLabel jl, jl1, jl2, jl3, jl4, jl5;
private JTextField jText, jText2, jText3, jText4;

What wrong am i doing here in this code which in not considered to be an extensible design ?
I am learning Java on my own and I am taking on very small project by myself for fun, and I'm just stuck on this small part of the project.
So 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.
I'm having trouble with this program. In my textbook it says "Write an application that displays a frame containing two panels. Each panel should contain two images (use four unique images - your choice). Fix the size of the first panel so that both of its images remain side by side. Allow the other panel to change size as needed. Experiment with the size of the window to see the images change orientation. Make sure you understand why the application behaves as it does". I successfully imported the images, but I can't find out anywhere how to allow the second panel to change size with the window.
import java.awt.*;
import javax.swing.*;
public class TwoPanels
{
public static void main(String[] args)
{
JFrame frame = new JFrame ("Embedded Images");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ImageIcon iconOne = new ImageIcon ("glove.jpg");
ImageIcon iconTwo = new ImageIcon ("cleats.jpg");
ImageIcon iconThr = new ImageIcon ("bat.jpg");
ImageIcon iconFou = new ImageIcon ("baseball.jpg");

I developed a swing application using group layout. It resizes when I resize the frame but when I change the screen resolution or when I run the application in a laptop which has small sized screen, the components over lap each other. I need my application to fit according to the screen resolution
The code is as follows
private void initComponents() {
jComboBox1 = new javax.swing.JComboBox();
jButton1 = new javax.swing.JButton();
jButton2 = new javax.swing.JButton();
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();
jLabel3 = new javax.swing.JLabel();
[Code]...
According to the list item selected, an internal frame will appear in the desktop pane. I use group layout for that internal frame too.
I have my paint application, i use the following mouse event to draw my shapes (mousePressed, mouseReleased, mouseDragged). Now after the user paint a circle for example, he must be able to drag the shape; to be able to do this. i think i must again implement the different mouse Events. I have done it and the drag is not working. How can i achieve this. can we implement multiple (mousePressed, mouseReleased, mouseDragged) in the same java class??
