I finally figured out that my applet needs to be signed for it to work. So I've spent the last few hours figuring out how to do that. I used the keytool to create my .crt file, then created the .jar file using jarsigner. After I did all of that, nothing has changed with my applet. I made the applet with netbeans, so in my netbeansprojects folder, I use the html that is made to run my applet, and it does nothing different. Shouldn't I get a security prompt when I open it? Can somebody please help me. I pretty much made copies of the jar and crt files and placed them in every folder in case it was a path problem.
