In the header I have a combo list. At each change in value in the combo list I have an Ajax request that updates the data in the Body. So far everything is working properly. Now the home screen's structure should be change when the value of combo list change. To do this I have :
- 1 ManagedBean HomeBean that manage the home - 1 ManagedBean HeaderBean that manage the header - 2 object HomeScreen1.java and HomeScreen2.java that allows me to valued data from each screen - 2 services HomeScreen1Loader.java and HomeScreen2Loader.java that manage loading of each type of screen - 1 template home.xhtml - 2 fichier home1.xhtml et home2.xhtml
When I log in to the application, I get the good page corresponding (Element type 1 => home page 1). But when I select a type 2 item, the actionListener methode is execute, ManagedBean's data was updated (for type 2 screen) , but the page does not updated. What do you do ?
Whether it is possible to force the installation of JRE when trying to open JNLP file. It is quite often case when users try to run JWS application without JRE installed. The best option would be to force the installation or at least display some message with instructions. Perhaps there are different ways to handle this problem.
I'm a beginner fiddling around classes in Java. I noticed on this particular code, Eclipse will give me an error and suggest I put the static keyword in front of the variable.
public class test { //the following line is where Eclipse puts the static keyword static FileAccess hello = new FileAccess("D:" + '\', ".mp3"); public static void main(String[] args) { for (int i = 0; i < hello.getTotalNumberOfFiles(); i++) {
[Code] .....
The FileAccess class is just a class I made while trying to retrieve filenames from my hard drive.
As far as I can tell, it works correctly after I put the static keyword there. I just want to know why it is required in this particular code, considering it didn't need to do that when I made a simpler class while I was getting my feet wet at creating classes in Java.
In other words in a table view with several editable columns, when a new row is added this row does not contain any column cells yet. Cells are added on demand once a column gains focus and starts editing. Is this the case? Is there any way to force the row to construct all cells eagerly?
I noticed that when building a UI programmatically in several steps the width/height of the Pane I use for layout is -1/-1. I read that this is the case until the actual rendering happens. Is there a way to force that earlier? Suppose I wanted to size other UI components (which are not visible initially) according to the size of another pane. How do I do that? Binding the properties does not do the job in the case that those components are not necessarily visible at the same time. Is there a trick to achieve that?
We've implemented the Whitelist and there's an application I need to use the Force attribute with, however, I'm unable to get this to work. As I read it, this code says use Java 1.6_24 for Example.com and any other applications are blocked from running. There are three versions of Java installed - 1.6_24, 1.7_65 & 1.8_25. The Java console shows 1.8_25 being called.
Here's the ruleset.
<ruleset version="1.1+"> <rule> <id location=https://example.com /> <action permission="run" version="1.6_24" force="true" /> </rule> <rule> <id /> <action permission="block"> <message> This application is blocked due to Java restrictions, please contact the Service Desk for assistance.</message> </action> </rule></ruleset>
I also tried
<action force="true" permission="run" version="1.6.0_24" /> and also <action force="true" version="1.6.0_24" permission="run" />.
The Java console is still showing version 1.8.0_25.
How to force browser to open/save/save as the file from server instead of browser cache.
I am creating a csv file through a pl/sql procedure and forwarding the link to user once user clicks on link he downloads the file, however if the same thing is repeated then browser returns the old cached file instead of new file generated on server.
New to java/programming and i cant understand why the pen variable does not display the the correct value ... For example for input 1 ; 2 ; 3 ; 4 both variables will display 10 and i dont understand why pen does not have the value 6 .
import acm.program.*; public class Chap4_ex12 extends ConsoleProgram { public void run () { int pen = 0; int r = 1; int sum = 0; while (r !=SANTINEL) { r = readInt(" ? "); pen=sum ;
Variables defined in interface are public static and final so I was thinking that we should not be able to override the variables in a class thats implementing the interface. But when I am compiling the below class, it compiles fine and gives the correct values. but when I did disp.abhi = 35; it gives a compile error (cannot override final variable)
interface display{ int abhi = 10; void displayName();
This is my first time working with C++ and I have put together this program and came up with two errors and I am unsure what it is wanting me to do. The errors I got are:

I am new in this programming language, java. I have a problem after I set my path ";C:Program Files (x86)Javajdk1.7.0_51in". I made a simple program but an error occurred. Here's the screenshot.....
I continuously get an error for lines 34, 36, and 37 saying that the variables may not have been initialized.
import java.util.Scanner; import java.util.Random; public class MathTutor { public static void main(String[] args) { Random r = new Random (); Scanner input = new Scanner (System.in); /*int min=1; int max=10;*/ int num1,num2,operation; int n1= r.nextInt((9+1)+1); int n2= r.nextInt((9+1)+1); operation= r.nextInt(3); int correctAnswer; int userAnswer;
Let's say within a class I create a method that takes care of creating a java swing layout with labels, buttons etc.. then attach an action listener (inner class) for each button to change a respective label text. All I would need is that the action listener method can access and modify the label as needed.
Have read about static, protected, private, getters and setters but honestly bit confused about which structure should be adopted as a best practice. Global static protected variables for the labels along with private inner classes implementing ActionListeners believe will do the trick and will be able to access the labels but not convinced this is good practice.
you can also refer this link Local variables in java?Local variables in java?To meet temporary requirements of the programmers some times..we have to create variables inside method or bock or constructor such type of variables are called as Local Variables.
----> Local variables also known as stack variables or automatic variables or temporary variables
----> Local variables will be stored inside Stack.
-----> The local variables will be created while executing the block
in which we declared it and destroyed once the block completed. Hence the scope of local variables is exactly same as the block in which we declared it.
package com.javatask.in; class A{ public static void main(String args[]){ int i=0; // Local variable
Is there any way to save variables while I'm using applet as single runnable .jar file?
For example if I start app first time some variable has value of 100. While using app it changes to 200. After closing app it disapear and next run gives me 100 again instead of 200. Is there any way to save that 200?
I will like to add to the questions about constructors and its this. I have a class A with a constructor, i have a class B which initialize the constructor. also i have a class C which needs a variable in class A but doesn't need to initialize the constructor of A. the question how do i access the variable of class A without initializing the constructor.
Does a variable have public access modifier? if we can use it within the class and outside of the class then can i access a public variable as follows??
class mo { void display() { public int a=9; System.out.println(a); } public static void main(String[] args) { mo m=new mo(); m.display(); } }
ERROR: It shows 6 errors :-O. Error 1. illegal start of the expression 2. class,interface, or enum expected
I'm having some trouble figuring out how to change the value of a variable that is passed into a class. I've tried just changing the variable, I've tried changing it by using the this.variable command, and I've even tried calling the setter class from within the class to change it, but it's still not working right. The first class is the one with Main in it and I just feed it some dummy data:
public class ExamConverter { public static void main(String[] args) { // TODO Auto-generated method stub Age testAge = new Age();
[Code] .....
This is the other class to calculate the age the way we do it on psych tests - it might not be mathematically accurate, but it's what all the tables and such for raw to scaled score conversion are based on, so the math needs to be the same as opposed to "accurate" because of some months having 30 or 31 days, etc.
public class Age { //==================Properties================== // Variables for the test date and client date of birth private int TestMonth; private int TestDay; private int TestYear; private int ClientMonth; private int ClientDay; private int ClientYear;
[Code] ......
Based on this dummy data, the output is: Test: 5/4/2014 DOB: 5/5/1971 Age Years: 43 Months: 0 Days: 0
However, it should be: Test: 5/4/2014 DOB: 5/5/1971 Age Years: 42 Months: 11 Days: 29
Is it possible to have the value of an entered String to be set as the name of the String to be created whilst running.For example: String username= Keyboard.readString() & the user entered for example the word: "Hello".Is there a way how I can make the Java Program create another String named Hello (Inputted value of String username).
If this is allowed, what do I have to use and if possible show me exactly what I have to do with the example mentioned above?
