How do I sign a Java applet for use in a browser?
I'm trying to deploy a Java applet on my website. I also need to sign it, because I need to access the clipboard. I've followed all the signing tutorials I could find but have not had any success. Here is what I've done so far:
- Wrote an applet in NetBeans. It runs fine in the applet viewer.
- Made a .jar file out of it.
- Created a certificate by doing this:
keytool -genkey -keyalg rsa -alias myKeyName keytool -export -alias myKeyName -file myCertName.crt
- Signed it wtih jarsigner like this:
jarsigner "C:\my path\myJar.jar" myKeyName
- Made an html file containing this:
<html> <body> <applet code="my/path/name/myApplet.class" archive="../dist/myJar.jar"/> </body> </html>
When I open that html file, I never get the security confirmation dialog box (and thus get the "java.security.AccessControlException: access denied" error). This happens on all browsers.
Am I missing a step?
