Greetings,

I am trying to get the java applets working for a website I did not create. I finally figured out how to sign the .jar files with a valid certificate, so that seems to be in order. However, when I try to run the application, it asks if I want to "Block potentially unsafe components from being run?".
The application that it sites in the pop-up is one of the .class files used in the java applet. If I click "Don't Block", the applet still has an error and doesn't run. When I click "Show details", it says "Class does not match trust level of other classes in the same package." I'm not really sure what to
do from here, although from searching online I think it has something to do with applet consisting of mixed code.

Please Help!
Thanks

I tried out this website, but it told me "Assessment failed. No security protocols supported." ...I'm not quite sure what to make of that.

I just contacted InCommon, who provided me with the certificate. I'm hoping they'll be able to shed some light on what's going on.

Thanks for all the responses!

I am currently trying to update a few java applets for a website. As of right now, the applets are automatically
blocked on all computers when they are accessed because the newest updates
for Java have caused them to be blocked. I have determined that the
solution to this is to resign the .jar files that are used to run the
application with a new certificate.

I requested and received a certificate (in pkcs 12 format, a .p12 file), imported it into
the computer, and used it to sign the .jar files. However, I have been
getting an error after signing the .jar files stating that the full
certificate chain of the code signing certificate is not valid.

I am not sure what to do from here. I've done a lot of internet
searching for a solution but haven't really found anything that applies to
our exact scenario. Prior to working on this project for work, I have never had any experience with this kind of thing
I contacted someone in the IT department at the University at which I work and he thought that maybe one of the intermediates within the certificate was either missing or illegitimate.
I tried to check the path of the certificate using a method he recommended (using OpenSSL) but didn't really find anything of use. Beyond that

Prior to this project, I had absolutely no knowledge of anything related to Java applets or web design. I would really appreciate any help you can offer me! I'd like to get the website operational as soon as possible!
