Need help with signing applets

I'm trying to have an applet write a file on the client system, but I'm having issues signing my applet. I think I'm missing something and would appreciate any help. Here are the steps I am taking...
1) keytool -genkey -alias blah
2) answer all the questiosn
3) jar -cvf Applet.jar *
4) jarsigner Applet.jar blah
5) applet code in the html file is:
<applet code=Applet.class archive=Applet.jar width="900" height="600">
6) run applet: appletviewer Applet.html
I then get an AccessControlException. What am I missing? Also, why do I still get the AccessControlException when I run my applet through appletviewer? I was under the impression appletviewer automagically gave permissions, and the AccessControlExceptions were only when you tried to run the applet off a server.
Some test code I'm using (AccessControlException at the System.getProperty line):
                    File out = new File(System.getProperty("user.dir") + "test.txt");
                    FileWriter writer = new FileWriter(out);
                    writer.write("blah");
                    writer.flush();
                    writer.close();

It works now in my browser, after rebuilding jar and resigning. But it still doesn't work in Appletviewer...

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

Need help with an applet that will only run as an application

I am working on a slide show applet. The problem is that is won't run as an applet. I added a quite standard main method to stick the applet in a JFrame and this worked. I believe that the problem lies in how I am trying to open the files.
here are two of the methods that I believe contain part of the problem
     private void showImage( String image_name )
          image_file = Toolkit.getDefaultToolkit().getImage( image_name );
          display_image.loadImage( image_file );
          repaint();
     private void setFileFolder( String folder )
          file_finder = new File( folder );
          file_results = file_finder.list();
     }image_file is an object of class Image, display_image is an object of class ImageComponent (extends JComponent to draw an image), and file_finder and file_results are both objects of class File
I would greatly appreciate it if some one would help me with this.
The full source can be found at http://www.geocities.com/enchantedforest/3688/ImSP.zip

Ok. I got the image loading to work.
Now how do I fix the second method shown in my first post? It is needed to find all of the images in one specific folder so that the slide show can run.

Need help with Java applet, might need NetBeans URL

I posted the below question. It was never answered, only I was told to post to the NetBeans help forum. Yet I don't see any such forum on this site. Can someone tell me where the NetBeans help forum is located (URL).
Here is my original question:
I have some Java source code from a book that I want to compile. The name of the file is HashTest.java. In order to compile and run this Java program I created a project in the NetBeans IDE named javaapplication16, and I created a class named HashTest. Once the project was created, I cut and pasted the below source code into my java file that was default created for HashTest.java.
Now I can compile and build the project with no errors, but when I try and run it, I get a dialog box that says the following below (Ignore the [...])
[..................Dialog Box......................................]
Hash Test class wasn't found in JavaApplication16 project
Select the main class:
<No main classes found>
[..................Dialog Box......................................]
Does anyone know what the problem is here? Why won't the project run?
// Here is the source code: *****************************************************************************************************

I need help with an applet

dear experts:
I need to transfer a single parameter from an applet to a JSP page, in this case a String primitive, how can i do that???
thank you

If you are talking client side: use JSObject to talk to javascript.
Server side connect to the jsp page/servlet with HttpURLConnection opened through a URL instance and send the String/Object or add a query to the url.

Need help with my applet. I am new to applets...Please help..please...

Here is one method from the class:
public void update(Graphics g) {
          Dimension d = size();
               int w = sky.getWidth(this);
          int h = sky.getHeight(this);
               // If we've loaded the moving image, draw it.
          if ((w > 0) && (h > 0)) {
               g.drawImage(sky, ((frameNumber*12) % (w+d.width))-w,
     (d.height - h), this);
               g.drawImage(bird,x,y,this);
Okay. The applet runs. However, when the sky moves across as the background, as soon as it shifts completely off the view, it gets all wierd and blurry. Then, when it shifts in again, it goes back to normal. It's supposed to go from left to right, start again at the left again, and then go right again...going only right...How do I stop it from getting all wierd?
Also, the bird image gets all staticky...all I do is increment/decrement the x and y (private int variables) in the keyPressed method (with a multi-way if). I read somewhere the solution to this problem is double-buffering...which I don't understand how to implement with my images....Sky and bird are both GIFs...

If you don't get a great answer (or even if you do) a great resource that I suggest you read is an article entitled [How To Ask Questions The Smart Way|http://www.catb.org/~esr/faqs/smart-questions.html] . It will tell you how to formulate your questions so that the folks here will be better able to answer them. Good luck.

Help with signing applets

Hi everybody. How do I sign an applet so that the applet is granted file access? I want the applet to request file access only and nothing else. From the applet signing tutorial it seems like signing an applet will grant all or nothing security! But I only want file access and I want the popup window which users receive to say file permissions only.

I also developed an applet where I only want socket permission but not file permission. It is a chat applet which can connect to multiple servers and so I don't want it to be limited to the domain where it is hosted. I overcome that by signing it. But my customers will not run the applet because they do not trust the applet because they say it is requesting unlimited access to their files. They say they don't want the applet messing up the computer. How can I request socket permission only and nothing else?

Need help with Drawing applet

im in the process of making a network whiteboard as a project for college and i was wondering if anyone could help me with a problem im having. When my application minimises or a window is placed over the application the drawing is erased, even if a window is placed over a certain part of the application it erases the part it covers is there any way to stop this from happening i cant seem to fix it, any help is appreciated, thanks

You should be buffering what the whiteboard is to draw, either as a BufferedImage or in some
data structure so that you can refresh when asked to repaint. Are you doing that, or are you
just drawing new graphics as it arrives from the server?

Need help with signing up for dev program - questions

Greetings,
I am planning on signing up for the dev program and I will be making a game to upload into the apple store. When I try sign up for the dev program/apple id, my country is not in the available list of countries. I am currently living in Mongolia and there is no itunes store available here. Would I be able to sign up for the dev program and develop/upload/sell?

I am able to use the singapore store as I made this account using singapore as my region. If I do that with my dev account, will I not run into problems with billing/confirmation issues?

Wanted: Help with Signed Applet Tutorial

Below is the code that goes into the policy file (from the above URL). Now where do I put it on a windows machine? %HOMEDRIVE%%HOMEPATH%? What do I specify as the keystore?
How do I edit it for a windows machine running cygwin?
Thanks,

I was not having a problem and then out of no where on Sept. 13 my game rooms failed to load and this message started appearing. I have done everything asked of me to clear files both Internet and Java, to uninstall, re-install, etc...nothing works. Does anyone have an answer for a very non technical user?
