JSP :: Eclipse Project Window Shows Error But Code Editor Shows No Error
May 22, 2014
For my jsp file, the code editor shows no error, but the projects window shows an error. I built my project again, cleaned the project, restart eclipse twice and summoned cthulhu. But my project still shows an error. How do I find the cause.

I downloaded this code from Head First Java. But when I tried running it on Eclipse, it gives this error message.
import javax.sound.midi.*; public class MiniMiniMusicApp { // this is the first one public static void main(String[] args) { MiniMiniMusicApp mini = new MiniMiniMusicApp(); mini.play();
[code]....
and this was the error message: Jan 02, 2015 8:10:36 PM java.util.prefs.WindowsPreferences <init>Could not open/create prefs root node Software Java SoftPrefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.
I am working on a program that accept input file from user and then from the input file, it count the occurrence for each words then put those result into the output. However, after I run this program, nothing shows up in the output file. It is totally empty...It seems nothing wrong with my code... Here is my code
import java.util.*; import java.io.*; public class occurance { public static void main(String[] args){ String inputFileName=""; String outputFileName=""; if(args.length == 0){
I am working on a simple JAVA tutorial, not homework, where employee data is taken from an array and displayed on the console. The data is divided by department, age, name and for the Accounting and Information Systems departments, they are displayed in ascending order by employee age. Everything works except I am not getting the output to the console other than the titles. As I step through the debug, the data clearly is populating the array.
package SimpleJavaAssignment; import java.math.*; public class PrimeAgeChecker { public boolean PrimeAgeChecker(int age) { BigInteger bi = new BigInteger(String.valueOf(age)); boolean prime = bi.isProbablePrime(10); return prime; } }
My code is running via javaw on Windows 7 and XP. It sits in the background waiting for a barcode to be swiped, and then wakes up and asks a question. The trouble is that sometimes (definitely not always), it shows like this:
The code is:
public static void Question(String sTitle,String sLabel) { JFrame window = new JFrame(); // Create a modal dialog d = new JDialog(window, sTitle, true); d.setLayout( new BoxLayout(d.getContentPane(),BoxLayout.Y_AXIS) ); JPanel p1 = new JPanel();

Initially I though it might because I had another thread running which occasionally put up announcement messages in JFrames. But I have taken this out and the problem still persists.
When I open applications specially high graphics applications, the screen flashes with whole black display with a number of horizontal white lines then after 2 or 3 flashes it opens the desired program. What is the cause, is it low graphics memory, physically damaged screen or ?
Write a program that shows a square frame filled with 100 buttons labeled 1 to 100. Nothing needs to happen when you press any of the buttons. I keep getting errors i am a beginner.

I've got a problem in Eclipse. The below code is a part of my program, used for (re)starting a new game. The 'public static int' statement gives the error 'This method must return a result of type int'..
public static int playAgain(){ boolean validInput = false; do { System.out.println("Would you like to play a game? Please answer 'yes' or 'no'."); String playAgain = input.next();

I currently use Eclipse to maintain our Java application. I recently upgraded from Java 6 to Java 7. I updated my Eclipse projects to use the Java 7 .jar files. I can run the application from Eclipse via the Run Configuration.
I can also run the Ant build and it completes successfully. When I install the application on my desktop, I receive the "Java Virtual Machine Launcher: Could not find main class..." error. My CLASSPATH is set to ".".
So I am finishing up a GUI that randomly rolls a dice and shows you the dice face from a file that I have on my computer. It compiles fine, but when I open the GUI and press the button "Roll" it gives me errors and does not display the images.
I am pretty new to Java and I am working on a sample Search code from my textbook. I can't figure out why I am getting the following error because I copied the sample exactly as it is in the book. The error is illegal start of expression on the second to last line.
public class Search { public static final int NOT_FOUND = -1; public static int binarySearch( int [] a, int x ) { int low = 0; int high = a.length - 1; int mid;
the system I am using is blue jay and java. my problem is that I have this error message pop up whenever I try to compile any of my 6 classes. Three of the classes are cities, 3 others are shops, and the final one is a inventory called Player. The following is the error code that appears when I try to compile class THshopB or class CityB.
method run in class CityB cannot be applied to given types;required: Player; found: no arguments; reason: actual and formal argument lists differ in length
A similar error occurs for the rest of my City and THshop classes,except it replaces the class CityB with CityA and occurs in class THshopA, replaces CityB with CityC when occurring in class THshopC.The public methods of CityB and THshopB are shown below, as I believe that something is wrong with the public method of one or the other. I have the code [CItyB.run();}] inside of class THshopB, and run is the part that gets the red highlight error described above.THshopB public method
[ public static void shop(Player inventory){ CityB.run();}] CityB public method [ public static void run(Player inventory){ THshopB.shop(inventory);]
All of my THshop classes are written in the same format, and all of my City classes are written in the same format,
My issue is that when I run the code if I enter anything but 1, 2, or 3 the code breaks. I have spent hours trying to find the error. here is my code
import java.util.Scanner; public class Tester { public static void main(String[] args) { /** * constructor * pre: none * post: inherit values of other classes */ Car Car = new Car(); //inherits the properties of the Car class Truck Truck = new Truck(); //inherits the properties of the Truck class
There are 2 methods and a main one. The first is a void that creates a 3x4 2d array and the second is to search for a value in the array, if found it will return the number of the row that contains that value. If not, it will return -1, but I am getting 1 error and 1 dead code warning.I will put comments at the lines that contain the problems
import java.util.Scanner; class Question4{ public static void main(String[]args){ Scanner s = new Scanner(System.in); int x,n; System.out.println("Please input the value that will be used in the array"); x=s.nextInt(); System.out.println("What is the value you want to search for?"); n=s.nextInt(); createArray (x,n);
