RequestFocus fail in JApplet

I wrote a JPanel under a JApplet, I want to focus on a particular JTextField, but failed to do so. Here is my code.
<pre>
this.setSize(new Dimension(324,250));
this.getContentPane().add(JPanel1,new XYConstraints(0,0,324,250));
JPanel1.setVisible(true);
JPanel1.jTextField.requestFocus();
</pre>
hope anyone can help me. Thank you

JApplet with JFrame fails to load in browser

I have been making a Java program that runs a JApplet the program operates perfectly in NetBeans (the Java development kit), but when I run it in the browser, it fails to load.
The code is...
import java.awt.*;
import javax.swing.*;
public class CalculatorMain extends javax.swing.JApplet {
private Difficulty difficulty = new Difficulty();
private Troop[] troop = new Troop[7];
private Army army = new Army(troop);
private Calculator calculator = new Calculator(difficulty, army);
private CalculatorListener listener;
public void init(){
JPanel supreme = new JPanel();
supreme.setLayout(new BorderLayout());
for (byte i = 0; i < 7; i++) {troop[i] = new Troop();}
DifficultyPanel diffpanel = new DifficultyPanel(difficulty);
ArmyPanel armypanel = new ArmyPanel(troop);
JButton calbut = new JButton("Calculate Experience");
JLabel xpDisplay = new JLabel(" ");
CalculatorPanel calpanel = new CalculatorPanel(calculator, calbut, xpDisplay);
JFrame frame = new JFrame();
listener = new CalculatorListener(xpDisplay, calculator, diffpanel, armypanel, calpanel);
calbut.addActionListener(listener);
supreme.add(diffpanel, BorderLayout.WEST);
supreme.add(armypanel, BorderLayout.CENTER);
supreme.add(calpanel, BorderLayout.SOUTH);
frame.add(supreme);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
As I said, it does not work in the web browser (which is Internet Explorer 6.0). In the information window I open, the message is...

Any idea what might be wrong?

If you look at your error message you'll see...
java.security.AccessControlException: access deniedAh. Problem # 1 caused at
     at CalculatorMain.init(CalculatorMain.java:31)Problem #2
java.lang.NullPointerExceptionat

How can I change my JApplet into a JApplication?

I am working with a JApplet and am finding that some of my code only works in applications.
So being new to this, I am clueless as to how to change my Applet into an Application. I understand the difference in definition between the two, but when it comes to looking at Applet Code and Application Code, I am not able to see a difference. (Other than an Applet stating "Applet")
So, that being said how can I change my code so that it runs as an application and not an applet? Here is my current layout code

The code that doesn't work in my applet is the exit button code
else if (source == exitButton)
                    System.exit(1);
               }I also can't get my program to properly validate input. When invalid input is entered and the user presses calculate, an error window should pop up. Unfortunately it isn't. I compile and run my applications/applets through TextPad. So when I try to test the error window by entering in invalid info, the applet itself shows nothing but the command prompt window pops up and lists errors from Java. Anyhow, here is the method I was told to use to fix it.
private static boolean validate(JTextField in)
          String inText = in.getText();
          char[] charInput = inText.toCharArray();
          for(int i = 0; i < charInput.length; i++)
               int asciiVal = (int)charInput;
          if((asciiVal >= 48 && asciiVal <= 57) || asciiVal == 46)
          else
               JOptionPane.showMessageDialog(null, "Invalid Character, Please Use Numeric Values Only");
               return false;
               return true;
     }My Instructor told me to try the following, but I still can't get it to work.String content = textField.getText();
if (content.length() != 0) {
try {          Integer.parseInt(content);
} catch (NumberFormatException nfe) {}

Problem with Listeners/ requestFocus()

Hello,
I am new to Java (started learning two months back), There is a problem with the requestFocus() in the focusListener. The program does not return the focus to the object indicated in the requestFocus but it shows multiple cusors!!
The faculity at the institute where I am learning could not rectify the error.
Is the error because of the myMethod() which I am using. I had made this method to prove to my professor that we can reduce the code drastically while using the gridbaglayout.
The code which I had written is as under:
// file name ShopperApplet.java

Would it not be acceptable to check that each field has a value when Submit is pressed. If a field is found with no data then display the error message and return the focus to the empty field. This would solve the multiple cursors problem as you would not need any focusLost handler code.
If this is entirely out of the question then you will have to override some of the FocusManager methods to prevent the JVM from handling focus for you :
FocusManager.setCurrentManager(new DefaultFocusManager() {
// Override FocusManager methods here.

Creation of an applet JApplet in a desktop JDesktopPane

how its posible to load from a jar file an applet which come from package my.package.myclass of the jar file.

What about calling getLocation on the applet itself?
Otherwise, if you are using Swing, you can try (where "this" is the applet object):
javax.swing.SwingUtilities.getWindowAncestor(this).getLocation();
or
javax.swing.SwingUtilities.convertPointToScreen(this.getLocation(), this);
The latter should work, at least.

Why does this applet (with an audio clip) fail to load in a browser?

Hello Java Experts.
I am able to compile and run the applet in an IDE. The problem lies when I attempt to run the applet through a browser (such as Internet Explorer, Firefox, etc.). The entire applet fails to load (in the browser) when it includes code pertaining to audio clips, but works fine when it does not contain audio clip related code.
Here is a Short, Self Contained, Compilable, Example that illustrates my problem:
import javax.swing.*; // Required libraries
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class Music extends JApplet // Music class is a subclass of the JApplet class
    AudioClip music;
    public void init ()
        music = getAudioClip (getCodeBase (), "sample.wav"); // You may use your own audio file
        music.loop();
    public void paint (Graphics g)
        g.setColor (Color.blue);
        g.fillRect (0, 0, 800, 600); // THIS RECTANGLE IS NOT DRAWN (this is my test to see if the applet loads in the browser)
}Please try to run this applet in a browser so that you can point me to my mistake(s).
Thanks for the help in advance.

Here is a Short, Self Contained, Compilable, Example that illustrates my problem:>The 'example' part of it, fails to manifest here. Using that exact code, I was able to see a blue rectangle in both AppletViewer and FF. You might try..
1) Configuring the Java Console to open for applets by default - look in it for error messages.
2) Change the name of the WAV to something that definitely +does not exist+ at the code base. (That would most closely replicate my own testing experience - since there is no WAV available here).

JTextField and JApplet

How can I have the JTextField as defined below to get the cursor (Focus), when the Applet starts (the requestFocus method is not working)?
import javax.swing.*;
import java.awt.*;
public class MyFocusJApplet extends JApplet {
     JTextField     myTextField = new JTextField(20);
     public void init() {
          getContentPane().setLayout(new FlowLayout());
          getContentPane().add(myTextField);
          myTextField.requestFocus();
     public void start() {
          myTextField.requestFocus();
}

I searhed the forums and when modified my start method as:
     public void start() {
          SwingUtilities.invokeLater(new Runnable() {
                    public void run() {
                         myTextField.requestFocus();
I got the required results!
But I am not able to understand the above :-(

Netbeans nightmare Converting a JFrame class to a JApplet Class

Hello im not exactly new to java but im having problems getting my applets to work when i try other peoples example applets they always work but mine never seem to. here is what i am doing i wrote a card game in VB6 long story short i completely rewrote it in java because only ie supports ActiveX.
It works awesome as a stand alone App whilst in Jframe and with a main() sub.
I tried about 15 tutorials on how to convert a jframe to a applet with no success i always got errors and applet never loaded in browser.
then i found these tips on how to do it "really easy" of course when my applet loads and im not sure it even really does i get nothing but a grey box i never seem my components a bunch of jlabels with icons loaded that look like card images it all looks great in the design tab of NetBeans. I never see any of the controls in browser. These are the links to the two tutorials that spawned my trying this. http://forums.java.net/jive/thread.jspa?threadID=57965&tstart=0 http://forums.java.net/jive/thread.jspa?threadID=57965&tstart=0
well to quote this guy it feels like its going to take 100 years to figure this out google has a million links to junk when i try searches and sun has no great help for searching either on their documentation. my program is rediculously low tech and i cant seem to get it to do anything or work at all as an applet.
my class looks like this: i removed all the constructor code as it was making post too long my applet shows up normal in the preview window of Netbenas but just a grey square of browser not sure whats wrong please someone help me.. Thanks You

You shouldn't start a new thread when you've already created a recent one with the exact same subject matter:
[http://forums.sun.com/thread.jspa?threadID=5447497|http://forums.sun.com/thread.jspa?threadID=5447497]
And my advice in the previous thread still stands. Put your program in a JPanel so it's environment-agnostic, then create two wrappers for standalone apps and applets.
(or just use Java Web Start)
Also your program has all sorts of other problems. This is terrible coding:
private javax.swing.JLabel jLabel37;If you need lots of labels that all have the same meaning, put them in a collection. Give things meaningful names. etc.
If that code was generated by Netbeans....then this is an example why you shouldn't use code generation tools...

PLAYING SOUND WITHOUT JApplet

Hi there,
I'm a new member in Java Developer forums, I hope that I'll be an effective member..
for now I need help with java sound , multimedia
I'm developing a program that part of it is to play array of sounds (Not JApplet) I tried to use the function AudioClip(getClass().getResources("soundName.wav"); but it works only with JApplet
I want to play the sound without JApplet
I found that there is a package called javax.swing.sound.*;
but syntax error occured in my program.. that this package does not exist..
Please help me..

I am also having the same problem. I couldn't get sound to work with the applet based one. I have the below code, it compiles and when you run the program it runs the length of the audio file but there is no sound? Is there something missing?
import sun.audio.*;    //import the sun.audio package
import java.io.*;
public class sound{
    public static void main (String args[])
          try
          InputStream in = new FileInputStream("cows2.au");
          AudioStream as = new AudioStream(in);
          AudioPlayer.player.start(as);

Japplet in jsp

hi all
i cant understand what wrong i m doing....i m annoyed very much
my jsp page is in /UASEProject/Webcontent directory and applet class is in /UASEProject/Webcontent/registration directory and also its java file. jsp page is running successfully with the url htttp://localhost:9080/UASEProject/myjsp.jsp.but when i tried to access an japplet with the context specified below then in jsp at inserting area a red cross is displayed. the browser showing a message "applet not initited" and when i clicked in that red cross then the message was "applet loading failed".
i m using rational application developer and it uses the server 'IBM web sphere application server v6.1'
please.....check this out and give ur suggession.
this is my jsp page
<table>
   <tr>
      <td>
                 <jsp:plugin type="applet" code="NewJApplet.class" codebase="registration"
               width="600" height="300">
     <jsp:fallback>Could not load applet...</jsp:fallback>
               </jsp:plugin>
    </td>
</tr>
</table>i have tried with this also
<table>
   <tr>
      <td>
                 <applet code="NewJApplet.class" codebase="registration"
               width="600" height="300">
               </applet>
    </td>
</tr>
</table>

First, you shouldn't be calling paint with what you get from getGraphics(). You should update your state and call repaint() on the applet.
You should probably load the images with the media tracker in the init() method anyway and ditch that thread thing. Unless they're really large images which you want to load asynchronously.
Second, your onload init() thing in JS is kinda pointless. You might do that to have the applet trigger that method, but not onload, as that's right away. The browser shouldn't wait for the applet to start. to call onload. Anyway, an applet in a hidden DIV might not load at all anyway, in some browsers.

JApplet run in Debug mode but not in Run Mode in JDev3.1

Hi All
I am having a problem in running a JSP file which contain an JApplet. When I choose Run from the jDev, the applet seems to take a really long time to load and finally failed to load itself.
However when i choose run from debug mode, the jsp run perfectly by displaying the applet.
Any idea why?
thanks for any help

I just want to be able to tell lucreate to ignore the zones, but I get the same results when I use the "-x" qualifiers as well.
Any ideas?

1) I would move the creation of the frame to init. I like to create objects only then when they are needed. And when creating the class it is not needed. But it is needed when the applet starts.
2) You forgot to create a container that can hold objects. Try to create a JPanel where you can add your Buttons to. Then add the JPanel to the ContentPane.
public class JAppletExample extends JApplet {
    JFrame jfrmTest;
    JPanel jpnlTest;
    public void init() {
        // initializing objects
        jfrmTest = new JFrame("This is a test");
        jpnlTest = new JPanel();
        // setting parameters
        jpnlTest.setBackground(Color.white);
        jpnlTest.setLayout(new FlowLayout());
        jpnlTest.add(new JButton("Button 1"));
        jpnlTest.add(new JButton("Button 2"));
        jpnlTest.add(new JButton("Button 3"));
        // adding JPanel to ContentPane
        jfrmTest.getContentPane().add( jpnlTest );
        // setting size and visibility
        jfrmTest.setSize(400, 150);
        jfrmTest.setVisible(true);
}Hope this helps, Rommie.

How to invoke a method in JApplet from javascript.

We want to invoke a method in JApplet from javascript.
with the help Java Plug-in HTML Converter Version 1.3, we have generated OBJECT/EMBED tag for
the following applet tag.
<APPLET CODE = "SimpleApplet" WIDTH = 200 HEIGHT = 300 NAME = "simpleApplet"
MAYSCRIPT = true>
<PARAM NAME = "p1" VALUE = "v1">
</APPLET>
it is given the following code


<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
WIDTH = 200 HEIGHT = 300 NAME = "simpleApplet"
codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
<PARAM NAME = CODE VALUE = "SimpleApplet" >
<PARAM NAME = NAME VALUE = "simpleApplet" >
<PARAM NAME = MAYSCRIPT VALUE = true >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
<PARAM NAME="scriptable" VALUE="false">
<PARAM NAME = "p1" VALUE = "v1">
<COMMENT>
<EMBED type="application/x-java-applet;version=1.3" CODE = "SimpleApplet" NAME =
"simpleApplet" WIDTH = 200 HEIGHT = 300 MAYSCRIPT = true p1 = "v1" scriptable=false
pluginspage="http://java.sun.com/products/plugin/1.3/plugin-install.html"><NOEMBED></COMMENT>
</NOEMBED></EMBED>
</OBJECT>


But, even after trying to invoke method in the JApplet from javascript, it is not being invoked in
Netscape. it is being invoked from
IE after changing the scriptable = true. Is there any such parameter to change, to invoke the
method in JApplet from javascript?
can anybody give any suggestion?

hi there,,
well the same problem exists with my code also, NS fails to call the function from java applet... if u get the answer please mail me on [email protected]

OnMouseClicked Event Is Failing To Fire

After clicking on the blue rectangle while the program is running the onMouseClicked Event fails to fire. I am expecting a message to appear in NB's Output window. Below is the relevant source code in relation to handling the onMouseClicked event:
package javafx_test;
import javafx.scene.control.Control;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.scene.Node;
public class ControlTest extends Control{
    def rect = Rectangle{
        fill: Color.BLUE
        height: 20 width: 20
        onMouseClicked: function(me){println("Events are working perfectly!")}
    protected override function create(): Node{
        return rect;
}Have I missed anything in relation to handling the onMouseClicked event for the blue rectangle?

I upgraded my custom skinnable control (as shown in [Controls+Skins / CSS - Do Not Scale (BUG)|http://forums.sun.com/thread.jspa?threadID=5363533] in a compact form). I had some trouble, but with a little help from the MediaBox sample, I finally had something working.
The custom control is useless and ugly, but it does its work in testing the making of custom controls! :-)
Here is the code:
StyledControl.fx
public class StyledControl extends Control
// Data related to the control (the model)
package var count: Integer;
package var content: String;
public override var focusTraversable = true;
init
    skin = ControlStyler {}
package function Incr()
    count++;
    content = "{count}";
ControlStyler.fx
public class ControlStyler extends Skin
//-- Skinable properties
public var size: Number = 20;
public var fill: Color = Color.GRAY;
public var textFill: Color = Color.BLACK;
public var focusFill: Color = Color.BLUE;
var shape: Polygon;
var focusHighlight: Circle;
init
    shape = Polygon
      points: bind
        0.0, size * 2,
        size, size * 2,
        size / 2, 0.0
      fill: bind fill
    behavior = ControlBehavior { info: bind control.id }
    node = Group
      content:
        shape,
        Text
          x: bind size / 2 - 3
          y: bind size * 2 - 5
          fill: bind textFill
          content: bind (control as StyledControl).content
        Text
          x: 0
          y: bind size * 2 + 10
          content: bind control.id
      //-- Behavior: call controller for actions
      onMouseReleased: function (me: MouseEvent): Void
        (behavior as ControlBehavior).HandleClick(me)
public function ShowIncrement()
    var df = fill;
    fill = Color.RED;
    Timeline
      keyFrames: [ at(2s) { fill => df tween Interpolator.DISCRETE } ]
    }.play();
public function ShowFocus()
    focusHighlight = Circle
      centerX: size / 2
      centerY: -5
      radius: 5
      fill: focusFill
    insert focusHighlight into (node as Group).content;
public function HideFocus()
    delete focusHighlight from (node as Group).content;
public override function contains(localX: Number, localY: Number): Boolean
//~     println("contains for {control.id}: {localX} {localY}");
    return shape.contains(localX, localY);
public override function intersects(localX: Number, localY: Number,
      localWidth: Number, localHeight: Number): Boolean
//~     println("intersects for {control.id}: {localX} {localY} {localWidth} {localHeight}");
    return shape.intersects(localX, localY, localWidth, localHeight);
protected override function getPrefWidth(height: Number): Number { size }
    protected override function getPrefHeight(width: Number): Number { size * 2 }
ControlBehavior.fx
public class ControlBehavior extends Behavior
public var info: String; // Only for debug information...
var control = bind skin.control as StyledControl;
public override function callActionForEvent(e: KeyEvent)
    println("{info}{control.count}: KeyEvent: {e}");
    if (e.char == '+')
      Incr();
package function HandleClick(me: MouseEvent): Void
    control.requestFocus();
    // I miss onFocus() and onBlur() methods?
    (skin as ControlStyler).ShowFocus();
    Incr();
function Incr(): Void
    control.Incr();
    println("{info}: Ouch! -> {control.count}");
    var sk = skin as ControlStyler;
    sk.ShowIncrement();
TestStyling.fx
Stage
title: "Test Styling Controls"
scene: Scene
    width: 500
    height: 500
    content:
      StyledControl { id: "Bar", translateX: 50, translateY: 100 }
      StyledControl { /* No id */translateX: 150, translateY: 100 }
      StyledControl { id: "Foo", translateX: 250, translateY: 75 }
      StyledControl { id: "Gah", translateX: 350, translateY: 100 }
    stylesheets: "{__DIR__}controlStyle.css"
controlStyle.css
/* Default style of all styled controls */
StyledControl
size: 20;
fill: #FF8800;
/* Specify changes per control identified by their ID */
StyledControl#Foo
size: 50;
StyledControl#Bar
fill: #09FF0F;
text-fill: green;
focus-fill: dark-green;
}I have yet to discover how to handle focus transversal, ie. changing the style of the control when it receives or loose the focus, be it by keys (Tab/Ctrl+Tab when control is focusTransversable) or with mouse (I handle the focus gain but I don't know what if the previously focused control so I cannot remove it).
