Java digital signature

I am trying to run a web page that has Java applet, but it prompts me with a screen that says:

The application's digital signature cannot be verified. Do you want to run the application?

I know that as long as I check the box "Always trust content from this publisher", that prompt will not show up anymore. However, is there a way that I can tweak in the registry setting so that I can by pass that prompt without having to click on "Always trust content..."?

I don't think you're allowed to do that. Java has a white list for certificate issuers and if your certificate is not signed by one of those it's considered invalid. So by clicking the always trust content from this publisher you are adding the publisher to the white list.

What you want to do is make your computer open for the risk of Viruses and worms, so not a really good idea

Hi, where the white list is located at?
