This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I have signed my applet jar and all the related JAR's. Now my applet is working fine except for the WARNING "APPLICATION'S DIGITAL SIGNATURE CANNOT BE VERIFIED" which pops up when I run the applet in a browser.
Is there anything else left I need to do after signing, to overcome this warning message???
What kind of certificate did you use - a self-signed one? If so, that's probably the reason for this; I don't think there's anything you can do about that (except of using a 3rd party certificate).
