Warning: The signer certificate has expired.
I get the following when I try to sign with jarsigner, and the output jar doesn't get generated.
How do I renew my jar signature?

The jarsigner command uses key and certificate information from a keystore to generate digital signatures for JAR files. A keystore is a database of private keys and their associated X. 509 certificate chains that authenticate the corresponding public keys.
You can optionally sign a JAR file with your electronic "signature." Users who verify your signature can grant your JAR-bundled software security privileges that it wouldn't ordinarily have. Conversely, you can verify the signatures of signed JAR files that you want to use.
Are you using a self-signed certificate? If so, you just need to use keytool to generate a new certificate, then sign your jar using keysigner.
If you are using a third-party signed certificate (Verisign, Thawte, etc), you'll need to renew your key using their online system (usually the same place you got the original cert).
