Java in 24 hours
i am just finishing java in 24 hours. but i am having trouble downloading files from the website www.java24hours.com. i also need to know how to put it into the same file as my java programs. how do i do it?
Usually, that's the first chapter in the book.
It's possible you're having trouble downloading the files because the website wasn't working when you tried it. Try again when you next have a chance.
As for actually setting up Java and making the files work - it really should be in the book. Don't get me wrong, but if the book doesn't tell you how to use the example files, then you really shouldn't trust the book to teach you how to program.
I would strongly recommend O'Reilly's "Learning Java" instead. Notice there's no "24 hours" in the title. "Learning Java" is much more thorough and will teach you far more than you can learn in 24 hours.

Hi y'all!!
I know of the free graphics repository that provides a set of basic icons
http://java.sun.com/developer/techDocs/hi/repository/
but this set doesn't contain what I need for my app:
I would like an hour glass, like the one displayed when you change the mouse cursor to a waiting cursor, but this should be in the Metal Java look and feel.
If anyone out there knows of anyother graphics repositories which may have an hourglass.. or if you know how else I can obtain one.. please, please could you tell me! You'd be saving me a lot of unnecessary time in painfully drawing one in an icon editor.
Thanks in advance you guys - later EddHmmm, google images "hourglass cursor" and may be:

Emulator runtime error - java.lang.IllegalAccessException
Hi
Im working through some example code, and when i build, everything is fine, with no errors, however when i run in the emulator, even though at this moment the program actually does nothing, its just a skeleton, i get the following error:
Unable to create MIDlet MyC
java.lang.IllegalAccessException
at com.sun.midp.midlet.MIDletState.createMIDlet(MIDletState.java:148)
at com.sun.midp.midlet.Selector.run(Selector.java:151)
For hours, i have been pondering over the code, but the answer eludes me as to why i get this error
Here is the main midlet:
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
public class my extends MIDlet implements CommandListener {
private MyC canvas;
public void startApp() {
if (canvas == null) {
canvas = new MyC(Display.getDisplay(this));
Command exitCommand = new Command("Exit", Command.EXIT, 0);
canvas.addCommand(exitCommand);
canvas.setCommandListener(this);
// Start up the canvas
canvas.start();
public void pauseApp() {}
public void destroyApp(boolean unconditional) {
canvas.stop();
public void commandAction(Command c, Displayable s) {
if (c.getCommandType() == Command.EXIT) {
destroyApp(true);
notifyDestroyed();
here is the class it uses:
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
import java.util.*;
import java.io.*;
public class MyC extends GameCanvas implements Runnable
private Display display;
private Sprite playerSprite;
private boolean sleeping;
private long framedelay;
public MyC(Display d)
super(true);
display = d;
framedelay = 33;
public void start()
display.setCurrent(this);
try
playerSprite = new Sprite(Image.createImage("/player.png"),12,12);
catch (IOException e){}
sleeping = false;
Thread t = new Thread(this);
t.start();
public void stop()
public void run()
Graphics g = getGraphics();
while (!sleeping)
update();
draw(g);
try
Thread.sleep(framedelay);
catch (InterruptedException ie) {}
private void update()
return;
private void draw(Graphics g)
playerSprite.paint(g);
flushGraphics();
}im using j2me, and yes, i have gone straight for
mobile phone midlet programming. That isn't going to be easy.
When i remove the
detail at the end of the constructor, the code wont
exectute at all. By looking at the code i presented
here, is there anything noticeable as to why i keep
getting this error?"Won't execute" doesn't tell me anything.
Removing the parameter means that you need to do other things to the code because there will be undefined items.
If you are copying code exactly as it appears in a tutorial then you need to be aware that you might be working with different versions of code (java and midlet) and/or there might be mistakes in the tutorial. Of course if you modified the tutorial code then you could be introducing problems as well. You can look for other sources of documentation which might provide more information as to what a minimal set up looks like. -
Hi,
We are trying to set up our deployments in sccm 2012 to wake up pc out off hours to install software and for the most part this works, however the problem we have is that if for whatever reason a pc doesn't get woken up (no power plugged in, no network connectivity
etc) it will not get the software and will not be woken up again by system center. The only way we can make this happen is by changing the deployment available time or the install deadline, as this seems to trigger sccm to send out wake up packets again. The
problem we have with this is that all pc's will wake up again even though there is nothing to be installed on them, so potentially we would have 50 pc's wake up just so 1 or 2 pc's can install some software.
For example, we want to install java out of hours so we have a deployment targeting a "java installed" collection and the deployment is set to send wake up packets. We schedule it to be available at 11pm and the deadline to be as soon
as possible. When the app becomes available, system center will send out the wake up packets and any pc's that can wake up will wake up and install the software with out causing any hassle to our users. Now, some pc's won't wake up for whatever reason and
therefore won't install the software, the user will come in and turn there pc on as normal and then the computer agent will realise that it needs java and try and install it. This means that we could end up with error messages coming up because the user has
a browser window open or even worse the browser window could close unexpectedly and lose any work the user was doing. We can't have this happen so we would implement a maintenance window to stop this, now the problem would be that come the start of the maintenance
window that evening, the pc will be turned off but system center won't wake the machine up because the deadline has passed. We would also run into this problem when adding a new machine to the collection, wol won't work because the deadline has passed.
Is there something we are missing here as it seems the wol functionality in system center is very dum and doesn't recognise non compliant machines?
ThanksUsing the built-in toolset, no, there's nothing that will really do this automatically as ConfigMgr has no way truly tracking which systems were and were not woken up and then correlating that with successful deployment execution. Not that is couldn't
be made to this with some extra design, development, and coding, but it simply doesn't.
You could though. Based on the compliance of a deployment, you could create a collection of systems where the deployment hasn't run (dynamic based on the compliance) and target a simple package (that doesn't do anything) but would trigger ConfigMgr
to send a OWL packet. This deployment would execute every night and the collection would contain systems that have not successfully completed any deployments you wish to push put this way.
Note that if the users aren't logging off at the end of the day though, you've pretty much got the same problems though.
Another way to handle this is to let the users known why going on using something like the PowerShell Deployment Toolkit on CodePlex.

Interesting difference between books and tutorials
I started coding in Java about four years ago. When I started I learned from a book (that I no longer have), I think it was "Sam's Teach Yourself Java in 24 Hours". I was just a kid then and I became fairly proficient in all of the basic requirements and such. Now, four years later, I am looking into getting back to Java when I can find the time, and possibly getting a certification. Instead of the book, I now use the online tutorials and API docs. Something I noticed about the tutorials is that they use coding methods that I never saw in the book. For instance from this tutorial on using the SpringLayout, the code follows this syntax:
import /*neccessary items*/
public class SpringDemo1 {
* Create the GUI and show it. For thread safety,
* this method should be invoked from the <----I didn't add this. Guessing it has something
* event-dispatching thread. to do with preventing the thread from crashing...?
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new JFrame("SpringDemo1");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//SpringLayout code here....
frame.pack();
frame.setVisible(true);
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}whereas, when I learned from the book, I always did this and I still do:
import /*neccessary items*/
public class myClass extends JFrame {
public myClass() {
//set up GUI here
public static void main(String args[]) {
myClass mc = new myClass();
}If I am going to get my certification, I don't want to be using practices that could cause a program to crash and get someone angry at me. If I am doing something wrong, please chew me out. It's better than losing a job...The book is old-fashioned, that's all. Neither version of the code is so bad that it will crash and you will lose your job and become a drug addict accosting people on the street for money.
The "extends JFrame" version was the usual way to write things back in the early days of Java. And then people started thinking more about object orientation, and noticed that there was nothing in most Swing programs which created a modified JFrame. They simply used the features of a JFrame to get their work done.
So under the flag of "Prefer composition to inheritance", the OO people rewrote the standard Swing application to do that. And so they should... Java is an object-oriented language, after all, so why not do things right? Let's not extend JFrame (inheritance) if we can just create one and use it (composition).
Of course they couldn't go back and change all the paper books and all the thousands of programs that people had already written in the old way, but they could change the tutorials. And they did.
So my suggestion would be to follow the style shown in that tutorial. You won't lose your job over it. In fact being able to explain why you did it might even improve your status at your job. -
SO PLEASE RUN THIS CODE AND TRY TO RECTIFY THE ERROR AND SOLVE THIS PROBLEMS.
I WILL PLACE THESE TYPE TEXT NEAR BUYME BUTTON
WHEN RUN THIS CODE FIRST IT WILL COME SCREEN LIKE "WELCOME TO SHOPPING CART"
SELECT BOOKS AND CLICK ON SHOP YOU WILL COME "BOOK CATALOGUE" SCREEN
TYPE AN INTEGER VALUE IN QUANTITY FIELD LIKE(2 OR 3 OR 4)
WHEN YOU CLICK ON BUYME BUTTON THE DATA SHOULD GET SAVED WHICH IS NOT HAPPENING
IF YOU COULD RESOLVE THIS PROBLEM IT WOULD BE GREAT

If you truely want someone to work with your code then you need to follow a few points of curtesy (I would say this thread is fairly dead).
1.) When you post know that you need to use code tags to get the code to show indents, which will help anyone that may be willing to look at your code.
2.) CAPITLAIZATIONS IN A TEXT MESSAGE IS CONSIDERED YELLING AT THE AUDIENCE.
3.) post what you have done to correct the problem and what symptoms you see. Specific errors and where you believe you are having problems.
4.) know this--if you cannot get it done, and are not seamingly willing to put any more effort into getting the problem corrected than putting it out on the web in a public forum and saying: "Here it is, fix it for me." Don't expect us to care if you fail your class or not. Many of us have already been through the classes and have had to do it ourselves or fail, so we buckled down and spent many sleep deprived years earning our degrees rather than asking others to do our work for us.
If you want help, post in a new thread and follow some curtesy and formatting. -
Problem redering h:outputText tag on a jsp fragment
Hello to all... I'm trying to understand and use this new technology and I have encountered a problem that I cannot find any documentation as how to solve it. First I have my welcome.jsp page that I am using to call my fragment:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@taglib prefix="c" uri="http://java.sun.com/jstl/core"%>

<h1><h:outputText value="Java Server Faces" /></h1>
<f:subview id="banner">
<c:import url="/banner.jsp"/>
</f:subview>
</f:view>
</body>
</html>then I have my jsp fragment, banner.jsp:
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@taglib prefix="c" uri="http://java.sun.com/jstl/core"%>

<td> <h:outputText value="#{msgs.hour6}" /> �</td>
<td> <h:outputText value="#{msgs.hour7}" /> �</td>
<td> <h:outputText value="#{msgs.total}" />� </td>
</tr>
</table>My problem is that the <h:outputText> tag is rendering the values outside the table. This is what gets displayed:
Java Server Faces
Hour1234567TOTAL
If I copy/paste the table tags (including the <h:outputText> tags) on the main jip, it renders without any problem:
Java Server Faces
Hour 1 2 3 4 5 6 7 TOTAL
I'm guessing that I might be missing some other jsf tag inside the jsp fragment. Any help will be greatly appreciated.
-thanks
RolandoI can suggest you with the following solutions
1. try having <%out.flush();%> before and after c:import
2. try with jsp:include with flush=true
Can you reply back with which one works? I didnt try out both of them

I am using JNI in my Java application , 12 hours after running my test case get a JVM crash -

I have added checks for this function call to ensure that no invalid pointer is being sent to it which could cause a segmentation violation.
Please could someone give me some pointers on how to solve this problem, the error occurs at this point only 12 hours after running the test case..First step is to add the option -Xcheck:jni to your java command line. It will flag common JNI errors.
If that doesn't identify the problem, then compile your jni code with debugging symbols (-g) and add the following option to the java command line when you run your test: -XX:+ShowMessageBoxOnError. When you hit the problem again, the VM will keep the process alive instead of calling abort(). Then you can use dbx to attach to the live process and should be able to get a better idea of what went wrong. -
Background application in Mac OS
Is it possible to run a Java application purely the background in Mac OS X?
I can set up a cron-like job to execute a java application every hour or something, but then the application takes up space in the Dock. I'd like it to run as a daemon or something.
Thanks in advance!

I need help. I am trying to learn using the Sams teach yourself Java in 24 hours. In its HOUR 4 it says to create an applet. it uses something called "Graphics screen" in its paint method. but when i use this it says that it cannot find symbol Graphics2d. i have no idea what is happening.
The code looks like this
package rootapplet;
import java.awt.*;
public class RootApplet extends javax.swing.JApplet {
int number;
public void init() {
number = 225;
public void paint(Graphics screen) {
Graphics2d screen2d = (Graphics2d) screen;
screen2d.drawString("The square root of "
+ number
+ "is"
+ Math.sqrt(number), 5, 50);
i am using JDK 1.6.0_02 and netbeans 6.0 beta. Can anyone help. i really want to learn and i don't want to skip any lesson. i had no problem in that book uptill nowjava is case sensative. Graphics2d is not the same as Graphics2D.
next time please use code tags when posting code. -
Hey I am about 3/4 through the book Teach yourself java in 24 hours...and so far every applet I have done has not loaded in the browser but stayed the gray box of doom... bla bla not found.
I am using Jcreater as a compiler and have the newest runtime enviroment.
Java:
import java.awt.*;
public class BigDeptApplet extends java.applet.Applet{
int debt;
public void init(){
debt = 59000000;
debt = debt / 1440;
public void paint(Graphics screen){
screen.drawString("A minute's worth of debt is $" + debt, 5, 50);
Html:
<html>
<head>
<title>The Big Debt Applet</title>
</head>
<body bgcolor="#000000" text="#FF00FF">
<center>
This a Java applet:<br>
<applet code="BigDebtApplet.class" height=150 width=300>
You need a Java-enabled browser to see this.
</applet>
</body>
</html>
please help...the code is straight from the book and compiled fine..Just when I open the html the applet doesn't load.I also noticed your class is called BigDeptApplet and your HTML refers to <applet code="BigDebtApplet.class". Not much difference, but enough. I only wish I could only spot my own mistakes.
That said I still haven't got your applet working in I.E. 6 on X.P. even though I know in the past I have managed it in the same browser & O.S.
Hopefully somebody will add to this thread, good luck. -
Initial setup problems and beginner code questions ...please help?
Hi,
Two days ago i started playing around with Java but it has been one pitfall after another for me. I am a visually impaired user, the fun started when i wanted to install the JDK. I think i got EE 5.0 by mistake, but that doesnt even bother me that much. The installer somehow managed to totally elude the screenreader I was using and I needed sighted help to get the thing installed. I think something went wrong with the environment variables during that process because when I first tried compiling a snippet of code it couldn't find Javac. I had to enter:
c:\sun\sdk\jdk\bin\javac.exe c:\saluton.java
to get anything done. I have been trying to learn java using a three-year old copy of teach yourself Java in 24 hours, which might explain my following questions. Here is the code snippet i got from the first chapter:
class Saluton {
public static void main(string[] arguments) {
// my first Java program goes here
String greeting = "Saluton mondo!";
System.out.println(greeting);
This code didn't compile, complaining about Cannot find symbol.
I took out another book, Learning Java, and i got the following code out of this:
public class HelloJava {
public static void main( String[] args ) {
System.out.println("Hello, Java!");
This code did compile, but when i tried:
c:/sun/sdk/jdk/bin/java.exe HelloJava it said the class couldn't be found. I am assuming this has to do with the .class file not being in the folder where it should be, but again I don't know.
I got the JAB (java access bridge) but I had the feeling the info that came with it is rather outdated ...could someone give me some insight on this as well?
Thanks very much for any help you all can provide,
FlorianHi,
Using your help I've been able to find the error in the saluton mondo program, the caps of the String in the main function declaration was wrong. I have set my Path to the right setting now, and javac and java behave as they should now which is good.
What about my question about the access bridge? How do i use it, exactly? (just telling me where that info can be found is enough really) I'm really confused by all the different .jar files and such ...
Also, once it is installed do i need to somehow ...activate it or reference it in my code to make my apps readable? I would like to see if my program did what I wanted it to do so yeah ...
Thanks for any help,
Florian -
Hi guys merry Christmas in advance .i was trying to write a code to compare given string with current date .
So i have written a piece of code to set hour minute second millisecond of current date to 0.
It worked fine for minute second millisecond but hour always shows 12.
Here is the code.
Please help
import java.util.*;
public class SampleDate
public static void main(String[] args)
java.util.Date date = new java.util.Date();
//convert current date to cal format and set hour min sec mill to 0
java.util.Calendar cal1=java.util.Calendar.getInstance();
cal1.setTime(date);
cal1.set(java.util.Calendar.HOUR,0);
cal1.set(java.util.Calendar.MINUTE, 0);
cal1.set(java.util.Calendar.SECOND, 0);
cal1.set(java.util.Calendar.MILLISECOND, 0);
//convert from cal to date format
date=cal1.getTime();
System.out.println("Current Date in Date Object: " + date);
}Output:
C:\TIMECOMPARE>java SampleDate
Current Date in Date Object: Thu Dec 24 12:00:00 IST 2009Expected output is :Current Date in Date Object: Thu Dec 24 00:00:00 IST 2009The HOUR field of the Calendar class represents a 12 hour clock format where 0 indicates 12 noon. Instead use the HOUR_OF_DAY in the code as shown below:
cal1.set(java.util.Calendar.HOUR_OF_DAY,0); -
Jdk Won't Appear under Program Files
I recently grabbed "Java Programming 24-hour Trainer" and began learning Java, and I encountered a problem that I have no clue how to fix.
I downloaded the latest Java Developer Kit, and when I had it installed, I couldn't locate the JDK Bin under Program Files to link up with the Command Prompt to emulate the "HelloWorld" script. Is there a solution to this?Hi,
When you had installed jdk in drive, suppose its shows as below
