Java Forum / Security / August 2003Webstart Signing JARs
Hi, I'm using Webstart to deploy a java application from cd. It looks like I need my jar files to be signed otherwise I can't use this deployment technology. It's an application rather than an applet so doesn't need a browser. Can anyone point me in the right direction? I'm new to Java. Thanks, Kevin. > Can anyone point me in the right direction? >I'm new to Java. see http://mindprod.com/jgloss/jarsigner.html and follow the links. It is actually quite trivial. Create a phony cert using Keytool. See http://mindprod.com/jgloss/keytool or buy one. See http://mindprod.com/jgloss/certificate.html Then sign the jar with jarsigner. You have to write a JNLP file, but other than that, it is no different from writing an application. You don't have to put anything strange in your code. see http://mindprod.com/jgloss/javawebstart.html -- Canadian Mind Products, Roedy Green.

The java application I'm deploying is contained in jar files and needs access to read and write files. I don't seem to be able to deploy using web start unless I sign the jars. Could I get away with a phoney cert, maybe I need another installer that doesn't insist on signed jars? > > Can anyone point me in the right direction? > >I'm new to Java.

For a captive audience they can install your phony cert or just say YES I trust you anyway. -- Canadian Mind Products, Roedy Green. Coaching, problem solving, economical contract programming.
