EJB / EE :: Nested Jar Files Not Working While Included In Web Project
Sep 12, 2014
I have created a standalone project and included its jar file in lib folder as follows :
Sample->lib>jar files
sample->src->source files
After constructing my Sample application jar file as sample.jar and trying to include it in my another web project as follows:
WebSample->WebContent->WEB-INF->lib->sample.jar
and constructed war files as WebSample.war
After deploying it is not able to access jar files of sample application and throwing NoClassDefFoundError. Where as if I am running it as standalone project it is working. What is best solution to resolve this issue.

I've been working quite a bit with a login system the past couple of months and I now have a version that I would like to try "for real" by extracting it as a runnable .jar or .exe file. I've looked at a couple of guides that told me how to do this properly, but even after following every step precisely it didn't work.
One of the guides I tried: 3 Ways to Create an Executable File from Eclipse - wikiHow
Double clicking the file or selecting it and pressing enter does nothing, the computer loads for a second and then nothing happens. I don't receive any visible errors when extracting the program, either.
However, when running the file from the command prompt I do receive an odd error:
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.
C:UsersUserName>java -jar Login.jar
Exception in thread "main" java.lang.IllegalArgumentException: input == null!
at javax.imageio.ImageIO.read(Unknown Source)
at LoginSystem.Data.updateData(Data.java:347)
at LoginSystem.Data.<init>(Data.java:309)
at LoginSystem.MainFrame.<init>(MainFrame.java:42)
at LoginSystem.MainFrame.main(MainFrame.java:457)
C:UsersUserName>
I must say I don't quite understand the error, it seems to be unable to load an image which is odd considering the program works fine without any errors at all in Eclipse.

Suppose you have an abstract class say Sparrow that extends the abstract Bird class. The abstract Bird class has the abstract methods, fly() and run()
How many methods from the Bird class should you implement in the Sparrow class?

I have an fxml page with a TabPane element with two tabs tabOne and tabTwo:
<BorderPane fx:controller="lc.controllers.ControllerOne" xmlns:fx="http://javafx.com/fxml">
<center>
<TabPane fx:id="tabPane">
<tabs>
<Tab fx:id="tabOne" closable="false">
<text >ONE</text>
[Code] ....
As you can see above tabTwo has a separate fxml included within.
Now some of the tab content in tabTwo needs to be refreshed based on the actions performed in tabOne. But however initialize method of included tab action class is called only once for the first time when the fxml page loads. How the initialize method of tabActions.fxml can be forced to execute every time the tab loads?

I tried many times to return a string from java project to an android project But it keeps sending incorrect values as in 2 as it should be 1 here is an example.
Java Project:
boolean somethingboolean = false;
if(something.equals("1")){
somethingboolean = true;
}
public static String getString(){
if(somethingboolean == true){
[Code]...
Android project:
System.out.println(JavaProject.getString())
and in the android project it prints "FALSE"
So what should i do?

I'm supposed to use a for loop that runs until it reaches the number input by the user, but I'm not sure how to tell the program to add the user's number along with all of the even numbers in between the user input and 2.

In a program I created, I'm using a text file that contains some texts needed for the program. The method relevant to this is something like the following.
private String wordgen(){
try {
BufferedReader reader = new BufferedReader(new FileReader("src/Resources/adjectives.txt"));
Random rand = new Random();
int low = rand.nextInt(400);
String fil="";
int i=0;
while(i!=low){
[Code]...
The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?

I need to transformation the txt files into xml files, but each row txt files don't have same elements, for example the first book is composite one author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
</books>
but the second book is composite two author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
<author>Author2</author>
</books>
I would have the xml files with the number of authors variables, I can use JAXB for my problem?or not?

I am in the process of creating a calculator GUI that calculates different answers based on inputs two main comboboxes and numbers in the appropriate textfields. The first one allows the user to choose from 18 different materials, while the second has the user choose between two different shapes. In a brief word explanation, here's how it's set up:
User chooses material.
User chooses shape.
User types in appropriate values.
'Calculate' button clicked.
If shape = rectangle, execute rectangle calculation.
Else if shape = cylinder, execute cylinder calculation.
Everything works just fine with zero errors on all 18 materials and all kinds of decimal numbers when the second shape is selected. So the math and layout is solid. However, when the first shape is selected, it returns a $0.00 answer regardless of the input values (still no red-line errors). In efforts to troubleshoot, when I have /* Cylinder section */, the rectangle section works to a 'T'. This, I believe is caused by poor formatting in the syntax of the 'if' 'else if' in regards to the shape combobox.
//If 'Rectangle' is selected:
if(shapeDropDown.getSelectedIndex()==1) {
//6061
if(materialDropDown.getSelectedIndex()==0) {
String msg0 = "The price is: $"
+ currencyFormat.format((0.098*(number2*number3*number4)*3.06));
totalPrice.setText(msg0);
[code]....

just trying to learn it on my spare time and I'm doing do-while loops
public class help {
public static void main (String args[])
throws java.io.IOException {
char choice, ignore;
do{
System.out.println ("Choose one:");
System.out.println("1. if");
System.out.println("2.switch");
[code]....
It makes no difference in the program wither i delete this block or keep it..how while (choice < '1'| choice >'2'); translates? I would assume it would be while (choice >= '1'| choice =<'2');?

Question: you are only allowed to use numbers from 1-6. Write a program to find all the permutations when three numbers are multiplied together to give a result 8. one number cannot occur twice in any permutation.
public class number4
{ public static void main(String[] args)
{
for(int a=1; a<=4; a++)
{
for(int b=1; b<=4; b++)
{
[Code]...
my program also prints out 2 2 2. but i'm not allowed to do that. how can I stop it from printing 2 2 2 ?

how a nested for loop increments the outer loop and then the inner loop and then when it runs the inside code.I've ran the program a few times but I'm just not understanding it, need little narrative to it?
for(int i=0; i < 5; i++){
System.out.println("i - " + i);
for(int j=0; j < i; j++){
System.out.println("j - " + j);
count++;
}
}

Here's what "Why doesn't this work?" question. It concerns a small method which is part of a card game.
I'm trying to check a condition from a section of an array, without a predetermined number of times any given call to this method will require a check. How much of the array I'm checking could vary greatly.
Is it at all possible to nest a for loop yielding a variable number of boolean && conditions inside an if? Am I just missing the right bracketing or is this nesting (if that's the word) even possible in the language?
To clarify, below is broken code. Compiler isn't letting me accomplish this goal as I envision it.
public boolean isFlanking() {
boolean f;
int reach = Math.abs(selectorX - targetX);
if(rival.getDeck()[selectorX].getPile().isEmpty() == true &&
[Code] ....

int count = 0;
for (int x = 0; x < 3; x++)
for (int y = x; y < 3; y++)
for (int z = y; z < 3; z++)count++;
What is the value of count after the code segment is executed?
The answer is 9, but I don't really understand how this answer was derived.
