I get the following error on a self-signed jar:
jar verified.
Warning:
This jar contains entries whose certificate chain is not validated.
Re-run with the -verbose and -certs options for more details.
I signed the jar like this:
"C:\Program Files\Java\jdk1.7.0\bin\jarsigner" -keystore myKeyStore myJar.jar myAlias
My jar has 2 entry points: One for java web start, and one for an applet.
Using the -verbose and -certs options shows a lot of lines. And I don't understand anything of this. This is the output: output.txt (part of the 6307 lines reproduced below).

How to sign the jar file ?
Just one line answers you question I guess. And if you look closer you'll see it. Here it is
[certificate is valid from 17/08/11 17:32 to 24/07/11 17:32]
As I may hope, you know that today is not July 24 so you just have to re-sign your app
