MORE INFORMATION

Steps to Reproduce Behavior

1. Create the following file, naming it DatagramSocketDemo.java:

   // DatagramSocketDemo.java
   // ======================
   import java.awt.*;
   import java.net.*;
   public class DatagramSocketDemo extends java.applet.Applet {
     Label label=new Label("");
     public void init() {
       setLayout(new BorderLayout());
       add(new Button("Click me to create a Datagram"),"North");
       add(label,"Center");
     }
     public boolean action(Event ev, Object ob) {
       try {
         DatagramSocket ds=new DatagramSocket(9000);
         System.out.println("Succeeded");
         label.setText(
           "Bug Fixed -- successfully created a DatagramSocket."
         );
       } catch (SocketException ex) {
         ex.printStackTrace();
         label.setText("SocketException: "+ex.getMessage());
       } catch (com.ms.security.SecurityExceptionEx ex) {
         ex.printStackTrace();
         label.setText("Bug -- SecurityExceptionEx:  "+ex.getMessage());
       }
       return true;
     }
   }
   						

2. Compile the DatagramSocketDemo.java file, creating a DatagramSocketDemo.class.
3. Create an HTML file named DatagramSocketDemo.html with the following code:

   <HTML>
   <HEAD>
   <TITLE>DatagramSocketDemo</TITLE>
   </HEAD>
   <BODY>
   <APPLET CODE=DatagramSocketDemo width=600 height=100>
   </APPLET>
   <HR>
   <A HREF="DatagramSocketDemo.java">The source.</a>
   </BODY>
   </HTML>
   						

4. Put DatagramSocketDemo.java, DatagramSocketDemo.class, and DatagramSocketDemo.html in the same folder on your Web server.
5. Open DatagramSocketDemo.html from Internet Explorer.
6. Click the button in the applet.
7. You should to see the message "bug - SecurityExceptionEx: cannot access port 9000"
