I used to put applets out on the web but as they got bigger and more people used them I figured I'd do better with webstart.
I then had to use a (self) certificate even when there was nothing running outside the sandbox.
My certificate expired and I couldn't work out how to extend it so I deleted it and created a new one.
[root@checkmypages swarm]# keytool -list -keystore keystore.jks
Enter keystore password: xxxx

Keystore type: jks
Keystore provider: SUN

Your keystore contains 1 entry

mykey, Dec 7, 2013, keyEntry,
Certificate fingerprint (MD5): xxxxxxxx
[root@checkmypages swarm]# jarsigner -keystore mjrsoft AlienSwarm.jar "xx xxxx"
Enter Passphrase for keystore: xxxxx

Warning: The signer certificate has expired.

I'm confused. Can I correct this and how?
Is there a better way than using certificates as users keep getting popup warnings and it just looks very poor.
