After a jar is signed and the -tsa option was used, how can I validate that the time stamp was included? I tried:
jarsigner -verify -verbose -certs myApp.jar
But the output does not specify anything about the time stamp. I'm asking because even if I have a typo in the -tsa URL path, the jarsigner succeeds. This is the GlobalSign TSA URL: http://timestamp.globalsign.com/scripts/timstamp.dll and the server behind it apparently accepts any path (ie. timestamp.globalsign.com/foobar), so in the end I'm not really sure my jar is time stamped or not.
