Make a copy of the .jar file that is being loaded in your browser (make sure it is NOT the unsigned one initially created by NetBeans). Once you have made a copy of the file, change the extension from .jar to .zip and open with any zip program such as WinZip (.jar files are just .zip files anyway). Now look in the folder called META-INF. You should see three files; MANIFEST.MF, and two other files ending in .DSA and .SF. If you don't see the .DSA and .SF files, then your applet has not been signed correctly. If everything is in place and your applet is definitely signed, then you may have encountered a bug in your version of Java. There are lots of bug reports out there for this sort of thing. Update to the latest JRE and if the problem persists, start a thread on the official forum asking for help: http://forums.sun.com/forum.jspa?forumID=30 Good luck and let me know how you go.

Are you clearing your classloader cache after building the .jar file? If you are using the applet from within a browser like Firefox or IE, you must clear the classloader cache in order to load the new version of the applet. Simply refreshing the page is not enough. This should also force Java to re-evaluate the applet's permissions. To clear your classloader cache, open your Java Console and press 'x'. Hi Patrick.
