Is it possible to use a server certificate to sign a java web start app? What I want to know is if will it work. I have a trusted certificate for my server, and I would like to reuse the same certificate to sign an app. 

Right now, I have this warning:

> 
> This jar contains entries whose signer certificate's ExtendedKeyUsage
>  extension doesn't allow code signing. This jar contains entries whose
>  signer certificate's NetscapeCertType extension doesn't allow code
>  signing.
>

> 

Will I be able to launch my app without the warning that the certificate is not trusted?
