Dec 8, 2014so recently i made an applet and i was gonna put it up on my website when i got an error saying that java had blocked the applet duo to security thingys..sooo i looked in to it and i found out that apparently you need permission from java to run a applet or something like that, because there was a lot of viruses coming from there or something...

View Replies View RelatedChange File Extension On Path Name In JTextField
Nov 3, 2014I have a GUI that has three jTextFiled's. The first on gets filled in with a file that I choose and shows the path to that file with the file name
i.e. - c:

Swing/AWT/SWT :: How To Change CheckBoxTree From FileSystemView To File
Mar 5, 2015I am trying to use a CheckBoxTree that has been already created here: [URL] .... The problem which this JTree is that is uses FileSystemView for the root directory and as far as I know it does not set any root directory.
So I want to have the ability to give it a root directory. for example: new File("C:Temp") So when the tree appears , it lists files and folders in the provided address, and not the entire system.
The code is available in the provided GitHub. I tried to replace all FileSystemView fileSystemView in constrictors and bodies with File file to make it working. It worked but ended up with errors such as not showing the file icons.
How to modify it correctly or if there is any better way to convert FileSystemView to File?
Change Specific Lines In Text Inputted From A File

Strategy To Change File Extension And Read Library
Sep 19, 2014I need to be able to select a file (compressed), change its file extension (to zip) and load all its content, preferably as objects. If it makes things easier one can assume all these files to be of the same type.
The content of the zip file are placed in folders, known Beforehand which might make things easier.
Enterprise JavaBeans :: Change Default Context Of EAR File
Mar 19, 2013I'm deploying an EAR file on weblogic 10.3.4. The EAR file contains a war file and a jar file that implements web services using EJBs.
The application deploys and is functioning correctly. The application is available from the following URLs:
web application: [URL] ....
web services: [URL] ....
However, I would like configure the deployment to insert the "app1" string into the URL so the application is available like this:
web application: [URL] ....
web services: [URL] ....
I've been looking at some of the configuration options in deployment plans, but can't seem to get anything working.
Swing/AWT/SWT :: Why Does ItemStateChanged Only Change Just Once
Mar 5, 2015I have a strange problems. Perhaps some of you already have had this problem before.
I have method which is suppose to check if the itemstate has changed. It ONLY works ONCE?
Thereafter, it does not matter how many times I changed the selection of the ComboBox.
Basically I have two Comboboxes.
1. If Combobox 1 is selected (e.g. Dogs, Cats)
2. Then get information from what ever the item from ComboBox 1 is selected, and display on ComboBox 2. (Dog Name, Cat Name etc)
E.g.
So If I selected Dogs on Combobox 1
Then display the Dog Names on Combobox 2.
If I then change and select Cats on Combobox 1,
then display Cat Names on ComboBox 2.

Looping Doesn't Change Value
Apr 28, 2014Write a program that asks the user for the low and high integer in a range of integers. The program then asks the user for integers to be added up. The program computes two sums:
The sum of integers that are in the range (inclusive), and the sum of integers that are outside of the range. The user signals the end of input with a 0.
Your output should look like this:
Sample input/output
In-range Adder Low end of range: 20
High end of range: 50
Enter data: 21
Enter data: 60
Enter data: 49
Enter data: 30
Enter data: 91
Enter data: 0
Sum of in range values: 100
Sum of out of range values: 151
This is my assignment and below is my code.
import java.util.Scanner;
class InRangeAdder {
public static void main(String[] args) {
Scanner scan = new Scanner (System.in);
int low, high, data=1, rangesum=0, outrangesum=0;
[Code] ....
The problem is that the program simply gives an output of 0 for both "rangesum" and "outrangesum". I don't quite understand why that is. Also i have a quick question, the program needs me to end the program when the value of data is 0 but in order to initialize it I need to give it a value. Usually I would give it a value of 0 like I have for rangesum and outrangesum but if I do the program does not run till the loop as it considers the value of data to be 0 and ends the program right away. What would be a work around to this and when do I need to have a value to initialize an integer? for example, I do not need a value for low and high. Is this because the program recognizes that a value is going to be defined but cannot do that for the other integers as they are inside a loop?

Calculator That Change Input Value Into Another Value
Nov 14, 2014I am currently working on a small java programm. I use netbeans for it. And obviously I am new to java.
Basically its a calculator that change the input value into another value: like 10 € into whatever $ and same with Inch and Centimeters.
Therefore I need a second jDialog Form where i can change the factors for the calculator and start the calculator again.
Here is my problem: I can open the second Dialog but if I want to change the factor it doesn't change the value in the variable and the second calculator frame is with the old factors. It seems the double variable isn't working globally
I will add the files later when i find out how?
JSF :: CommandLink - Cannot Change Content
Mar 4, 2015I'm a first timer at jsf, and right now I'm learning how to use ajax in jsf. i got a problem when i click a command link i want to change in a content, but when i run my web and i click the command link it didn't do anything. This is the source :
<?xml version="1.0" encoding="UTF-8"?>

In this code when i click the Home button it suppose to change the ouput text to a string that store in my bean. This is my bean:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package UI;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

At first the output text value is the same as the string i store in the bean. but when i click the commandlink, it didn't do anything, is there something wrong with my code?
How To Change Value Of Boolean Within A Method
Dec 1, 2014I read in a book that when you change the value of a method parameter that's a boolean or other basic datatype within the method it only is changed within the method and remains the same outside. I want to know if there is some way for me to actually change it within the method. For example:
public class Change {
void convert(boolean x, boolean y, boolean z) { //i want to set x,y, and z to false in this
x = false;
y = false;
z = false;
[code]...
I want to put in part1, part2, and part3 when i call the method than i want them to be set to false within the method. The specific reason i asked this question was because im trying to code a battleship and i have a subroutine class with a method that when its called it checks if a ship has been sunk. If the there was a sink than the method will set a ton of boolean variables to false.
Just to clarify, I want something like this:
void convert(thing1,thing2,thing3,thing4) {
//some code here that sets thing1,thing2,thing3, and thing4 to false
}
// than in main:
boolean test1 = true;
boolean test2 = true;

How To Change Menu GUI With Buttons
Apr 23, 2014I have a GUI with a menu to do various options. However I want to change that menu to use buttons instead. I'm working with JSwing components and I'm a little familiar with the JButton function, but I don't know how to convert the menu to a button. I think I'll have to remove the menu completely..anyway I tried to start with the file menu but the compiler says no suitable method found for setForeground(javax.swing.JMenu). Why is it giving me an error related to JMenu when I'm using Jbutton objects? Can I not use JButton objects inside a menubar scope? I'll bold the area it highlighted:
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
