do share if you have any experience of this sort..
Thanks.

Absolute Beginner needs help with applet

Hello folks,
I know I have already started a topic on this, but it was getting a bit long and I wasn't getting anywhere with it. Here's my problem... first of all, I am new to Java, especially with Applets. I attempted to create the HelloWorld applet from this site's First Cup of Java tutorial. I was able to compile the java file fine, but when I attemted to add the applet to an html file, I get a message at the bottom taskbar saying "load: class HelloWorld not found". I can't figure out what is wrong with my code. I have all my files (html, java, and class files) in one folder, with no subfolders at all. In case it matters, I'm on a Windows 98 machine with IE 6.0 for my browser. Here is the code:
First my HelloWorld.java file, which, as I said, compiles with no problems
import java.applet.*;
import java.awt.*;
* The HelloWorld class implements an applet that
* simply displays "Hello World!".
public class HelloWorld extends Applet {
     public void paint (Graphics g) {
          //Display "Hello World!"
          g.drawString("Hello World!", 50, 25);
}And here is the HTML file which is supposed to display the applet:
<html>
     <head>
          <title>A Simple Program</title>
     </head>
     <body>
          Here is the output of my program:
          <applet code="HelloWorld.class" width="150" height="25">
          </applet>
     </body>
</html>Can someone please check this and see what, if anything, is wrong?

Hi Chris,
This isn't going to help much. I took your Java code
and put it in a file HelloWorld.java. I took your HTML
code and put it in a file HelloWorld.html. I compiled
HelloWorld.java with javac so that I had HelloWorld.class.
I then ran the program with appletviewer by typing
appletviewer HelloWorld.html.
It loaded and ran fine.
Since that sounds like exactly what you are doing,
I'm not sure what else to suggest. (I could also
run it by opening the HTML file with IE.)
There are only two things that still suggest themselves,
and they seem like long-shots:
1) Is the file named HelloWorld.java that contains your
code (including the capital W)? This is obviously a
long-shot because your code shouldn't compile if this
was set incorrectly.
2) Is it possible that you have the CLASSPATH environmental
variable set? Some programs (like QuickTime for Java)
will set the CLASSPATH and then Java just stops working.
You can find out by typing SET at the command prompt and
looking for CLASSPATH. If you find it, then you'll probably
need to remove it from your AUTOEXEC.BAT (in Windows 98),
or update it to include the runtime classes for the SDK.

I need help with Applets and Multithreading

[hello all. first time poster. big fan of java.]
now to the important matter: Applets and Threads
=======================================
1) I have an applet with that implements the runnable interface, and has one thread (and a simple animation). If I try to view this applet in the applet viewer with JGrasp, it spits an insane error telling me
"java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)"
but, if I run the applet through a web browser, by putting it in an html document, it runs correctly, without error
What on earth is wrong, and how do I fix it?!?
2) I want to put 2 threads in my applet?
If I implement the Runnable interface, I can only have one Run() method in my applet, right?
So how do I define behaviour for 2 threads when I only have one run method in which to define the behaviour? Can I use two threads with the runnable interface, or do I have to make objects of my own defined thread classes?
3) I tried to make 2 threads in my applet by creating my own thread classes, and instantiating them in my applet (instead of implementing the runnable interface).
I still get the same insane error as I mentioned in my first point (which I expected), except now, the applet won't work even when viewed through a web browser!!
Please please help me. I am frustrated beyond belief (at what is probably a very simple problem)
I have searched and searched all over and found no answers on this

If I try to view this applet in the applet viewer with JGrasp, it spits an insane error telling me
"java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)"Don't know anything about JGrasp, but it runs with pretty tight security - thats what this insane error is all about. Use the appletviewer or a browser.
If I implement the Runnable interface, I can only have one Run() method in my applet, right?Correct
So how do I define behaviour for 2 threads when I only have one run method in which to define the behaviour?
Can I use two threads with the runnable interface, or do I have to make objects of my own defined thread classes?You can create two Runnable implementations (classes) in your applet.
example (missing code)
class MyApplet extends Applet {
void doSomething() {
void doSomethingElse() {
void startThreads() {
    Thread t = new Thread(new Runnable() { public void run() { doSomething();}});
    t.start();
    t = new Thread(new Runnable2());
    t.start();
class Runnable2 implements Runnable {
     public void run() {
       doSomethingElse();
}If the above seems confusing, read up on anonymous and inner classes.
3) I tried to make 2 threads in my applet by creating my own thread classesTry not subclassing thread - this causes a security check

Need help with applet related problems

First of all hello to everyone. I'm new to this forum. I usually can solve my problems google-ing around, but this time I just ran out of ideas.
I'm trying to develop a jni applet that can run native code for performance. I used netbeans so far and the applet works great when run from within the ide. At some point a managed to make the applet run inside firefox and iexplore, however somehow i screwed something up and now i can't make it run anymore. I don't really know what i did but i think it may be related to these lines in the console since everything up until awt works fine in the applet:
basic: JNLP2ClassLoader.findLibrary: Looking up native library: jawt.dll
network: Looking up native library in: C:\Users\Gladiator\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\10\1082924a-7851bf5e-n\jawt.dll
basic: Native library jawt.dll not found
Ofc i may be wrong.
This also my be a local problem because a friend of mine tried the applet himself and said it's working.
All the jars are selfsigned.
below i posted the console output in case you want to take a look. Also I am interested about the "try again.." messages that seem to pop over and over again.

I am sorry for bold, i came here to ask for help. I used bold to differentiate output from my questions since i couldn't find tags.
I already validated jnlp using JaNeLA and got only optimization suggestions.
As I said in first post, this works for a friend of mine, so it's possible a local issue with my java or something ...
Also i reinstalled jre/jdk 7.0, then uninstalled and installed latest jre/jdk 6.
Hope I didn't leave a bad impression, i just want help.

Need help with Applet: Images

DUKESTARS HERE, YOU KNOW YOU WANNA
Hi,
I'm designing an applet for some extra credit and I need help.
This game that i have designed is called "Digit Place Game", but there is no need for me to explain the rules.
The problem is with images.
When I start the game using 'appletviewer', it goes to the main menu:
http://img243.imageshack.us/img243/946/menuhy0.png
Which is all good.
But I decided that when you hover your cursor over one of the options such as: Two-Digits or Three-Digits, that the words that are hovered on turn green.
http://img131.imageshack.us/img131/6231/select1ch3.png
So i use the mouseMoved(MouseEvent e) from awt.event;
The problem is that when i move the mouse around the applet has thick line blotches of gray/silver demonstrated below (note: these are not exact because my print screen doesn't take a picture of the blotches)
http://img395.imageshack.us/img395/4974/annoyingmt1.png
It also lags a little bit.
I have 4 images in my image folder that's in the folder of the source code
The first one has all text blue. The second one has the first option, Two-Digits green but rest blue. The third one has the second option, Three-Digits green but rest blue, etc.
this is my code

Oh yes, I knew there could be some problem.......
Now try this:
boolean a,b,c;
if((a=(x >= 175 && x <= 330 && y >= 200 && y <= 235)) && !hoverButton[0]) {
               hoverButton[0] = true;
               repaint();
          } else if((b=(x >= 175 && x <= 330 && y >= 250 && y <= 280)) && !hoverButton[1]) {
               hoverButton[1] = true;
               repaint();
          } else if((c=(x >= 175 && x <= 330 && y >= 305 && y <= 335)) && !hoverButton[2]) {
               hoverButton[2] = true;
               repaint();
          } else if ((!a && !b && !c)&&(hoverButton[0] || hoverButton[1] || hoverButton[2]){
                    for(int i = 0; i < 3; i++) {
                         hoverButton[i] = false;
                    repaint();

Like i have an applet with a popup menu, so how do i get it so that when i click on it the second applet comes up??? how do u use the getDocumentBase method if thats how you do it.
saad

thanx that helped a bit, now i was getting exception errors nullpointerexception error, i put a try catch thiing in and so the applet runs but when i click on the button nothing happens... here is my code
when i click on the button it should compare the userid and password and ponce varified show the applet.
public void actionPerformed(ActionEvent actionevent)
String strUserName = new String("saad");
String strPassword = new String("khan");
if(strPassword.compareTo(txtPassword.getText())==0 && strUserName.compareTo(txtLogin.getText())==0)

catch(NullPointerException mue)
}

NEED HELP WITH APPLETS

I have created an applet that runs on a web page that needs to access a .csv file and read from it. When the applet runs on the web I get an error saying that "applet cant be instantaited" does this mean that there is a problem with security as mention in other topics, or is there something else wrong with it.
Try it:
http://www.chesterfieldac.org.uk/Results/NorthMen/2002/Match1/results.html
Can anyone help

Yes,
The applet is attempting to perform an operation, i.e. read a file that is not allowed by the applet's security manager. The solution is to sign the applet. The client will then be notified the code has been verified to be from "you" and they (the client) can choose to execute outside the "sandbox" that applets default to.
Here are a couple of links that you may find usefull:
JDK 1.3
http://java.sun.com/products/plugin/1.3/docs/nsobjsigning.html
JDK 1.4
http://java.sun.com/j2se/1.4/docs/guide/plugin/developer_guide/intranet.html
(particularly chapters 17, 18 and 19)
Good Luck,
Pete

Help with Applets causing Browsers (IE,NETSCAPE) to crash..?

Whenever there is an applet on a website, and I view it in either IE or netscape, it always crashes the browser.
I have downloaded the latest VM, so this isn't the problem. Any help would be great, thanks. :)

"I have downloaded the latest VM, so this isn't the problem."
Well, it might be. Your brower(s) might not support the JVM you have downloaded.
Try this "Start | Programs | Java Plug-in Control Panel" and then try and run Version 1.1. Does it work?

Help with applet page not opening please

Hi I hope somebody can help. I downloaded the Java Plug in 1.4.2_05 but the applet for my offshore bank account applet will not open - just a blank grey page appears.
I went to the test applet page and the following note came up. "You are using an older version of Java Technology 1.1.4"
I can see the dancing Duke logo.
I followed the instructions to download the latest version again and up pops a window saying that we have the latest version. I went through the FAQ page - also checked all the setting were correct. I have the coffee cup Logo. I can see the plugin control panel, also the Java website control panel. The draw4 and note pad applications open up.
I need to know why the banking applet will not load.
We are running Windows Explorer 6
Thanks
Michele

Hi there,
Your IE is using hte Microsoft IE JVM plugin, you'll need to install Sun's plugin for IE. Installing the JDK/JRE fresh usually gives you an option of what browsers to install the plugin to.
Hope that helps!

Please help with Applet in New Window?

I am trying to write a html page which opens appet into new window.
Tha'ts what i want. My applet has user/passwd authentication and then
makes a socket connection. However i am facing tow problems(kind of one):
1. If i close my applet browser window, socket connection is still active.
(if i use appletviewer.. every thing works perferctly)
2. on my web page, if i click again to open my appet window it refreshes my applet window again ....if it 's already opened. in other words, my applet does not really gets reloaded from my webserver..
Please advise..
Here is my HTML Code
index.html
<HEAD>
<SCRIPT TYPE="text/javascript">
<!--
function popup(mylink, windowname)
if (! window.focus)return true;
var href;
if (typeof(mylink) == 'string')
   href=mylink;
else
   href=mylink.href;
window.open(href, windowname, 'width=840,height=630,scrollbars=yes');
return false;
</SCRIPT>
<A
   HREF="NewJApplet.html"
   onClick="return popup(this, 'notes')">Loads Streamer </A>
</HEAD>NewJApplet.html
<HTML>
<BODY>
<P>
<APPLET code="NewJApplet.class" width=800 height=560></APPLET>
</P>
<HR WIDTH="100%"><FONT SIZE=-1>
</BODY>
</HTML>

You can open a frame, and have a very small applet on your html page. Perhaps you can set the applet size to (0, 0).
You could also open a new browser window that is not resizable and contains your applet in its full size and without the toolbar buttons and menubar. I think you need javascript to configure the new browser window like that.

Help with applets and shape/pixel detection

hi
im currently trying to write my first propear programming project, its a little evolving ecosystem but ive hit a stumbling block. im trying to write a method which returns an array of positions around a calling creatures location filled with numbers that refer to its surroundings, in the snippet below it places a 1 in reference to a prey. the method performs a pixel by pixel search of x y matches in an area around the calling creature, it then decides what location the reference is to be placed by working out which range of positions it is in.
unfortunately no one seems to recognise anybody or behave in the manner in which im encoding them to. i suspect its problem with my basic (and im sure crude) algorithm. if anyone has the time or indeed the inclination to look over this code and offer some opinion i would be very greatful indeed. or has anyone worked on a problem similar to this and could offer me some advice.
thanks
for(int index = 0; index < prey.size(); index++)
otherx = ((Prey)prey.get(index)).getXcord();
othery = ((Prey)prey.get(index)).getYcord();
for(int i = -8; i < 9; i++)
for(int j = -8; j < 9; j++)
if(otherx == xpos + i && othery == ypos + j && otherx != xpos
&& othery != ypos )
if(otherx <= xpos && otherx > (xpos - 8)
&& othery > (ypos + 3) && othery < (ypos + 8))
     objectsaround[zero] = 1;
else if(otherx <= xpos && otherx > (xpos - 8)
&& othery >= ypos && othery < (ypos + 4))
     objectsaround[one] = 1;
else if(otherx <= xpos && otherx > (xpos - 8)
&& othery <= ypos && othery > (ypos - 8))
     objectsaround[two] = 1;
else if(otherx >= xpos && otherx < (xpos + 4)
&& othery <= ypos && othery > (ypos - 8))
     objectsaround[three] = 1;
else if(otherx > (xpos + 3) && otherx < (xpos + 8)
&& othery <= ypos && othery > (ypos - 8 ))
     objectsaround[four] = 1;
else if(otherx > (xpos + 3) && otherx < (xpos + 8)
&& othery >= ypos && othery < (ypos + 4))
     objectsaround[five] = 1;
else if(otherx > (xpos + 3) && otherx < (xpos + 8)
&& othery > (ypos + 3) && othery < (ypos + 8))
objectsaround[six] = 1;
else if(otherx >= xpos && otherx < (xpos + 4)
&& othery > (ypos + 3) && othery < (ypos + 8))
objectsaround[seven] = 1;
}

I'm reposting the code with the formatting tags so that I can read it.
for(int index = 0; index < prey.size(); index++)
otherx = ((Prey)prey.get(index)).getXcord();
othery = ((Prey)prey.get(index)).getYcord();
for(int i = -8; i < 9; i++)
for(int j = -8; j < 9; j++)
if(otherx == xpos + i && othery == ypos + j && otherx != xpos && othery != ypos )
if(otherx <= xpos && otherx > (xpos - 8) && othery > (ypos + 3) && othery < (ypos + 8))
     objectsaround[zero] = 1;
else if(otherx <= xpos && otherx > (xpos - 8) && othery >= ypos && othery < (ypos + 4))
     objectsaround[one] = 1;
else if(otherx <= xpos && otherx > (xpos - 8) && othery <= ypos && othery > (ypos - 8))
     objectsaround[two] = 1;
else if(otherx >= xpos && otherx < (xpos + 4) && othery <= ypos && othery > (ypos - 8))
     objectsaround[three] = 1;
else if(otherx > (xpos + 3) && otherx < (xpos + 8) && othery <= ypos && othery > (ypos - 8))
     objectsaround[four] = 1;
else if(otherx > (xpos + 3) && otherx < (xpos + 8) && othery >= ypos && othery < (ypos + 4))
     objectsaround[five] = 1;
else if(otherx > (xpos + 3) && otherx < (xpos + 8) && othery > (ypos + 3) && othery < (ypos + 8))
objectsaround[six] = 1;
else if(otherx >= xpos && otherx < (xpos + 4) && othery > (ypos + 3) && othery < (ypos + 8))
objectsaround[seven] = 1;

        System.out.println("Stopping...");
}

// <applet code='Main' width='400' height='200' ></applet>
import javax.swing.*;
public class Main extends JApplet{
    public void init() {
        GUI inst = new GUI();
        getContentPane().add(inst.getContentPane());
        validate();
    public void start() {
        System.out.println("Starting...");
    public void stop() {
        System.out.println("Stopping...");
}Other notes:
- You try to set the PLAF to Windows. which will not work on Linux and Mac (and if it did, the users would be screaming at you).
- setLayout(null)/setBounds(int,int,int,int) is rubbish GUI development, it is fragile and will cause problems (especially if changing PLAFs)
- Why did you not code this as a hybrid application/app?
- The call to the JFileChooser will require a trusted applet, and it is pointing to the wrong place in seeking out the 'Program Files' directory, better to put configuration data/history data in a sub-dir or user.home.
- This app. is much better suited to being deployed using Java Web Start. Forget the applet and use the frame, persistence can be obtained through the PersistenceService and that will side step both the application needing 'trust' and trying to find a suitable path for storing results of past games. JWS can launch the app. directly off the net, and provides auto-update and many other slick features.

Need help with advanced applet

I need help with designing an applet as follows. Can someone give me a basic layout of code and material so i can fill in the rest or at leats give me some hints so i can get started since i am like no good at applets.
Design and implement an applet that graphically displays the processing
of a selection sort. Use bars of various heights to represent
the values being sorted. Display the set of bars after each swap. Put
a delay in the processing of the sort to give the human observer a
chance to see how the order of the values changes.
heres a website that does something similar
