Hello John,

Thanks for your reply. Sure. I can use appletviewer to test the applet.
However, my object is not this. I want to add a small code snippet to the
HotSpot VM so that it can print out the methods invoked information when an
applet is running. I think the appletviewer is linked with the HotSpot under
jdk7 directory. How can I link the appletviewer to "my" HotSpot project?
Does it mean I need to directly change the HotSpot code under jdk7
directory? Thank you very much.
