Error starting java applet

Hi,
I had an issue on starting the applet on the web browser(either IE or FireFox). The applet loaded and starts well in my colleagues machine(windows 2000 and jdk 1.5.0) but in my local machine, running the same OS and jdk 1.5.0, throws an exception. here is the detail of exception thrown.....

Im tracing the exception using the Java Console in the web browser and set the trace level to 5.
Any help will be very much appreciated.
Thanks.
