Hi,

I'm trying to make and applet that will contact another website, on
the click of a button from a webpage. In order to do this I've created
a Signed Applet below.. Where all the work of contacting the web page
is done in the shift4 class.

Anyhow, when I load this applet, it will contact the website (ie the
code validateCreditCard is run during the init). However when the
webpage calls this same code I get a security problem (Exception :
access denied ).

I would like to have this so it only does validateCreditCard when the
button is pressed. I only put it in the init for test.. Why does it
work one way fine, and not the other?

--- Code in FireFox Browser --
     <form name="shift4" method="POST">
         <applet id="shift4Processing"
code="com.webrezpro.browser.shift4Test" archive="./dist/
WebRezProBrowserJava.jar" width="300" height="300">
         </applet>
         <input type="button" value="Test"
onClick="alert( this.form.shift4Processing.validateCreditCard('http://
java.webrezpro.com/test/t.txt', 10000,'test=test') )" />
     </form>

--Basic Applet Setup
public class shift4Test extends java.applet.Applet{
   shift4 processing;

   /** Initializes the applet shift4Test */
   public void init() {

       try {
           java.awt.EventQueue.invokeAndWait(new Runnable() {
               public void run() {
                   initComponents();
               }
           });

           this.processing = new shift4();
           System.out.println( this.validateCreditCard("http://
www.google.com", 11000, "") );

       } catch (Exception ex) {
           ex.printStackTrace();
       }
   }
