Hi,


I am working on an  example  Chat Server in Ch 10, in the bookJava Servlet
Programming, by Jason Hunter.

The example is Chat Server application and demonstrates Applet - Servlet
Communication. When i run the servlet
 it displays an HTML page, and i have a choice to choose http or Socket or
RMI to be my mode of communication.
When i choose "http" as my choice, the applet corresponding to  this choice
'HttpChatApplet'  should be invoked.

But i get the error exception:
com.ms.security.SecurityExceptionEx[HttpChatApplet.init] in Internet
Explorer
and applet HttpChatApplet class HttpChatApplet could not be loaded in
Netscape.
(When i load the HttpChatApplet  alone it works fine.)

I am using JavaWebServer1.1.3. I have my Applet source and class file under
public_html and the servlets under the servlets directory.

Please advise how to deal with the SecurityException error.  How can i
figure out when a problem occurs  -- if it is in the Applet or the Servlet
or the JavaWebServer. Is there any debugging techniques / tools for servlets
?


Thanks in advance,
Vaishnavi
