Sign java applet without security pop-up

Question

I have question about signing java applets. I have self-signed applet. When i open webpage i have security warning dialog, and i have to confirm permissions. Is it possible (for example via SSL certificate or i don't know, some code certificate) that this dialog will not appear?

Answer 1

Get a certificate from a trusted authority, like Thawte or Verisign. This way you'll ensure your users, that you are a trusted party (so they might more willingly click the Always trust content from this publisher checkbox).

You - as an application developer - cannot disable this dialog completely, but your users can. Look at the Avoiding security chapter of this document to find out how.

Answer 2

Is it possible ... that this dialog will not appear?

Only if there is a security bug in the JRE.

If the code is digitally signed using a verified certificate, the security warning will be more mild, the signer identified in the dialog, and Always Trust might be checked by default.
