[Bluej-discuss] Applets

[Michael Kölling]

Hi Ashrak,

It seems that you use the SuM library in your program (via an  
'import' command). Unfortunately, access right to libraries from  
applets are a tricky problem. And even worse, the rules are quite  
different between web browsers and the applet viewer.

As a first try, you should try to run it in a web browser, such as  
Firefox.

Regards,

Michael
