Can we build java web start application using unsigned jars?

Hi,

When I saw the text field demo for java web start application in the sun's site, I did notice that the jar file which they used was UNSIGNED! But when I created my own jar file and tried to launch JNLP, my java web start application didn't start up as the jar file was not SIGNED! Then I signed the jar file I created and it was working fine.

How come sun's jars working though UNSIGNED? Can I also have UNSIGNED jars to start my web start application? If so, how?

Thanks and Regards,

Narendranath
