But when I access the applet using http://parag:8080/mine/TestApplet.html the lookup is done properly and the applet is started (parag is name of my computer).

Can someone please tell me why accessing from localhost throws AccessControlException.

Thanks and Regards,
Parag

[severityone]

It would help if you included the relevant parts of the HTML file, but my guess is that you load the relevant JAR and/or class files from parag. But parag and localhost are, from the perspective of the sandbox, two different machines. You're not allowed to load applets from a different machine (parag) than the one you're browsing on (localhost), so that's why you get the error.

Hope this helps,
