Applet problem with IE

hi fellas
I've got quite a stressing problem with my applets.
When I load them in the appletviewer there is no problem, idem in Netscape 7. But when I try with IE I only obtain a grey rectangle.
I thought I had written something wrong and I downloaded a free applet source on the net.
On the site where I downloaded this applet I could see the applet with IE. So I got the Java code and the source of the HTML page.
I compile the .java save the html source into a document and try to load it locally ... still a grey rectangle.
The same applet that I could see on the web page with the same source code embeded in the same html file.
So I thought that maybe my 1.4.0 sdk was the problem and I tried to recompile the .java with a 1.3 sdk ( hoping a compatibility problem )
---> Nothing ... Nothing
This drives me old before the age.
If anybody can help me ...
Thanks

here is the applet code
import java.applet.*;
import java.awt.*;
public class basicApplet extends Applet
     public void init(){}
     public void stop(){}
public void paint(Graphics g)
     g.drawString("Hey hey hey",20,20);
     g.drawString("Hellooow World",20,40);
and his is the html page
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<body>
<applet code="basicApplet.class" height="100" width="200">
</applet>
</body>
</html>
the html page and the applet are in the same directory.

EEM Applet Problem With: event syslog pattern ".*" priority 2

I went to create a EEM applet that would be invoked whenever any syslog message of priority 0-2 was invoked. I figured the following event statement would work
event syslog pattern ".*" priority 2
I never really used the priority optional argument before but thought I understood from the docs that messages at or numerically lower than the specified level are matched.
Well it doesn't seem to work as documented. Seems to me that only messages at the specified level are beng matched and not messages numerically lower than the specified level.
Anyway I did what I wanted differently but wanted to post this in case this is a bug in the syslog ed.

Actually, it's a problem with the documentation. The priority option only matches the specified severity. What you could do is adjust pattern to do this:
event syslog pattern "*-[012]-"

Applet: problem with cookie encoding for jar request (Firefox - Iplanet)

I have an applet working with a JAR file. When the JVM sends the request to the webserver for the JAR file, it adds to the request the existing domain cookies. However, one of these cookie is encoded, and on Firefox with Iplanet (webserver), it prevents the jar from being downloaded (server returns error 400).
Below the HTTP request (as given by Charles HTTP Proxy) for Firefox and Chrome. We can see that some characters differ for the aria_user_profile cookie.

Is there a solution to this, by setting an encoding on the applet tag for instance?

Applet problem with FileWriter() (security problem?)

btBut1.addActionListener(new ActionListener()
   public void actionPerformed(ActionEvent e)
       FilePermission perm = new FilePermission("<<ALL FILES>>" , "write");
      try {
            FileWriter outputStream = null;
            outputStream = new FileWriter("./bandiere/testouno.txt");
       catch (IOException eX) {
   });This is a bit of code from an APPLET which I'm working on. The code does not work...
I smell it is a security problem, but I'm not sure...

You are trying to write to the local file system which is not allowed unless the applet is signed.
Unless you think you are trying to write to the server, in which case, you can't do that with FileWriters. You'd have to make a connection to the server via a socket or URLConnection or something to pass the data over.

Signed applet problem with 1.3.1 but same workin in jre1.4

Hi,
I have performed the following steps to sign an applet
1. javac search.java
2. jar cvf Search.jar *.class
3. keytool -genkey -alias signFiles -keystore abs_stores -keypass
123456 -storepass 123456
4. jarsigner -keystore abs_stores -storepass 123456 -keypass 123456 -
signedjar SignedSearch.jar Search.jar signFiles
The applet searches for some files in the hard drive.
The problem is when I user Jre 1.4,IE 5.5 the applet works but it does not with
jre1.3.1
I need it to work with jre1.3.1.
can someone help me out.

Problems with pacman applet, and advice on a gaming portfolio

Hi
I recently made a pacman applet, im having a few problems with it though, the first time the applet is run on a browser, the ghosts(represented by squares) often dont appear or if they do, they are stuck in walls, this never happens when i run offline on my computer. Is this because the very first time the applet is run, it doesnt load properly, but the second time some of the files are in the cache so it loads fully?
Also everytime i refresh the browser the applet dissapears and is replaced with a blank space and a cross in the top left hand corner, does anyone know the reason for this?
The applet can be found below, if you do decide to play it, please bear in mind what i have said, so it might not load correctly the first time, if this is the case please refresh, or close the broswer and reopen the link! Also you will need to click the applet for it to gain focus before you can move pacman - use the arrow keys the control pacman.
http://www.renaissance-designs.co.uk/Satwant/java/pacman/
Id also be very gratful for some advice - id like a change in career, ive always wanted to get into gaming, ive had some previous knowledge in java i made a programme that could generate its own poetry in java for my dissatation, but i still never had a huge amount of confidence, and so went into websites.
BUT now i have decided to take the leap back into programming and give it a go, which is why ive made this game.
I thought id make a portfolio and try and apply for a few gaming jobs. This applet took me two weeks to make and it was in my spare time, i am fully aware its not perfect, and it doesnt look great, but i would like to know what people think of it, also how many more games do you think i should make, before i apply for gaming jobs? Does anyone have any advice on what would make a good portfolio for a java gaming job?
Thanks alot, i look forward to what you think of the game, and your advice!

Thanks for getting back to me with that information, i didnt know you could see that information with just a simple right click!
But im afraid that doesnt really help me solve the problem, im not sure what all of that information means! :SI have very little experience with applets, but I can tell you what I would do to debug this (forgive me if you already know this stuff).
Look at the stack trace you get in the Java Console that I posted earlier. Each line contains a method that was called from the method on the previous line. So, java.lang.Thread.run() called sun.applet.AppletPanel.run(), which called Room.init(), etc. Look at the topmost line whose method is something you wrote, not something in the standard Java libraries. In your case it looks like PaintSurface.java (specifically, line 22). Look at what line 22 of PaintSurface.java is doing, it's calling Thread.start(). If you check out the Javadoc for Thread.start(), it says IllegalThreadStateException gets thrown if you call start() on a thread that has already started. So that's your problem. Without looking at your code, I'd assume you want to stop your thread in your applet's destroy() override, and instead of reusing it, create a new one each time init() is called.
Ill try and look into, thanks again though, it gives me somthing to work with :D
Btw when you first ran the applet, did all the ghosts(3) load up correctly?Unfortunately, no. The first time I ran it, there was only 1 ghost (or maybe all 3 overlapping each other?) at the top of the screen, and they never moved. Refreshing once made the game play as I think you want it to. Refreshing a third time gave the dreaded red X.
...oh and just out of curiosity,,, did u have fun playing the game :DSure did.

Problem with JRE and Yahoo applets

Hi, I couldn't find any answer for this anywhere else...
Whenever I try to play a Yahoo game, certain windows will "shake". For example, if I log into yahoo, then go to play their spades game, the applet will load without any problem. The game room will appear and everything seems to be fine. But if I click on the Start Panel, the borders of the Start menu will "shake" If I right click on anything, that menu will also shake. This only occurs while JRE is running the yahoo applet. Once I leave the yahoo game, everything returns to normal. If I use IE and MSVM, this problem does not occur. This problem does not seem to occur with other instances of Java either. Only Yahoo games. I tried searching Yahoo for an answer to this, but didn't find anything. When I tried getting help from them, they replied with an email to update Java and/or my browsers. Well, I am using version 1.4.2_04 of java, and have IE6 updated as of today. Also, I am using Opera version 7.54 and Firefox 0.93. This problem with Java and Yahoo occurs no matter which browser I am using. The only way to keep this from happening seems to be to use IE with MSVM. Any ideas?

That page does apply. Everything that you have written indicates conclusively that the Yahoo game you're playing is the source of the problem. The fact that it works with the MS jvm but not with the Sun jvm, that the Sun jvm works with other Java applets, etc all say the same thing - that Yahoo applets wer/are coded to work with the MS jvm, which uses MS extensions in violation of the Sun/MS licensing agreements. The statement at the bottom of the page is proof positive - your spades game is not listed by Yahoo as being fixed.
"07/17/03 - From Yahoo! Customer Care:
We have deployed a fix for the incompatibilities with the Sun JVM� in the following games:
Chess Gin Cribbage Euchre Bridge
Hearts Toki Toki Boom Graffiti Pool
We plan to upgrade the rest of the games on an ongoing basis. "
The Yahoo applet is the problem and requires repair...

Problem with focus on applet - jvm1.6

Hi,
I have a problem with focus on applet in html page with tag object using jvm 1.6.
focus on applet work fine when moving with tab in a IEbrowser page with applet executed with jvm 1.5_10 or sup, but the same don't work with jvm1.6 or jvm 1.5 with plugin1.6.
with jvm 1.5 it's possible to move focus on elements of IEbrowser page and enter and exit to applet.
i execut the same applet with the same jvm, but after installation of plugin 1.6, when applet gain focus don't release it.
instead if i execute the same applet with jvm 1.6, applet can't gain focus and manage keyevent, all keyevent are intercepted from browser page.
(you can find an example on: http://www.vista.it/ita_vista_0311_video_streaming_accessibile_demo.php)
Any idea?
Thanks

Hi piotrek1130sw,
From what you have described, I think the best approach would be to restore the original IDT driver, restart the computer, test that driver, then install the driver update, and test the outcome of installing the newest driver.
Use the following link for instructions to recovery the ITD driver using Recovery Manager. Restoring applications and drivers.
Once the driver is restored, restart the computer and test the audio. If the audio is good you can continue to use this driver, or you can reinstall the update and see what happens. IDT High-Definition (HD) Audio Driver.
If installing the newest driver causes the issue to occur but the recovered driver worked, I suggest recovering again.
If neither driver works I will gladly follow up and provide any assistance I can.
Please let me know the outcome.

Problem with Applet for Microsoft VM

Hi there!
I implemented an applet (first for SUN JVM 1.4.1_02) that has to communicate with a servlet via serialized objects. Therefore the applet sends a request and expects the response :
//establish connection
URLConnection l_con= l_url.openConnection();
l_con.setUseCaches(false);
l_con.setDoOutput(true);
l_con.setDoInput(true);
l_con.setRequestProperty("Content-Type", "application/x-java-serialized-object");
//send request to servlet
ObjectOutputStream l_outputStream = new ObjectOutputStream(l_con.getOutputStream());
l_outputStream.writeObject(l_obj);
l_outputStream.flush();
l_outputStream.close();
//get response
ObjectInputStream l_obInStr = new ObjectInputStream(l_con.getInputStream());
l_response = (MyResponseClass)l_obInStr.readObject();
l_obInStr.close();This works absolutely fine for the Sun VM. Now I have to use the Microsoft VM (because I don't want the users to install anything on their clients).
I compiled the client classes like that:
javac -target 1.1 classname.javaThe applet starts correctly but there is a problem with the communication that I recognized in the console:
java.io.IOException: Cannot write output after reading input.
     at com/ms/net/wininet/http/HttpURLConnection.getOutputStream (HttpURLConnection.java)
     at myclass/MyApplet.callToServlet (MyApplet.java:109)
Does anyone know what this error means ?
Thanks a lot in advance.

Hi there!
I solved my problem by removing all the System.out.println-statements that I used for debugging issues.
Anyway, I want to know if there are more restrictions concerning this matter for using the Microsoft VM instead of the Sun VM. (Because it HAS worked with the debugging statements with the Sun VM).
Thank you.

Error loading class problem with applet (Newbie)

Hi,
I am new to Java applets. I try to display a simple sample. I put this into html file: <APPLET codebase="classes" code="NewApplet.class" width=350 height=200></APPLET>
And it always appears one problem:
Error loading class: NewApplet
java.lang.NoClassDefFoundError
java.lang.ClassNotFoundException: NewApplet
     at com/ms/vm/loader/URLClassLoader.loadClass
     at com/ms/vm/loader/URLClassLoader.loadClass

     at java/lang/Thread.run
Can anybody help please? Thanks in advance.

Now I am able to load the applet on MAC OS X 10.4.11. This is due to network issue.
Now my problem with the applet functionality. My applet will display the map image. Applet contains the navigation arrow keys at the top left of my applet. These keys will be used to navigate through the map.
The problem is while user using the navigation buttons, the image got squash and stretch.
This is happened only on MAC OS X 10.4.11 and Its working fine on PC and MAC OS X 10.5.5.
Please anyone help in this regard. Thanks in advance.

Problems with applets.

Hi to everybody.
I've got a problem with simple applets.
I've built several applets using Swing components (JApplet, JPanel, JButton, etc.)
In my browser, the background color of my applets does correctly appear.
But none of my components does !!!! No text fields, no buttons etc.
Can someone explain to me which could be the reason of that ?
Thank's.

I've just tried appletviewer. And I discovered that there is a problem while trying to acces to a jpeg file for my JBuutons and JLabel.
Appletviewer considers these files are on the client machine and refuses the acces.
But when I try my site, the server is my computer too ! So the jpegs are on the server side !
Furthermore, when I start my web page (that contains my applets), nothing does appear (no exception) in the java console...
How can I solve this problem (I'm newer with applets)?

[Solved]Problem with deskbar-applet

Hi to all, i'm having annoying problems with the deskbar-applet in gnome. I've installed it with pacman and no error occurred during installation but I can't perform any search on the web through the search-engine of firefox. They don't appear in action's list at all. And i don't manage to use the deksbar-applet with tracker. I compiled tracker from abs with the option --enable-deskbar-applet=auto. and copied tracker-handler.py and tracker-handler-static.py in the .gnome2/deskbar-applet/modules-2.20-compatible/ directory. Any advice??
Thanks
Solved. I had to copy tracker-module.py in that directory. Bye

Thank you, headkase, you were right about it! Removing "ck-launch-session" solved my problems. I also removed "dbus-launch" because I didn't have it there originally, I had added "dbus-launch" to exec line just today as I had read somewhere that it might help (it didn't)...
So, I'm going with "exec gnome-session" and everything works, thanks.
