Signed Java applet suddenly has mixed code warning

I have a signed applet on my website that had been working fine for nearly a year. Today, however, it's giving my users a mixed code warning. I found here that certain Apache components, which I happen to be using, can generate a mixed code warning. However, there are two things that concern me.

  1. First of all, my applet consists of a single jar file that's signed, and when I use jarsigner -verify my_signed_file.jar I get the jar verified output. (It's not linking to any external libraries, all of the compiled code is inside this jar file.)

  2. I'm getting this message all of a sudden, even though the my applet jar hasn't been modified in nearly a year. Both I and my client have been using the Java 1.7 runtime for a while now without getting this message, so why would we be getting the message today?

Any thoughts or ideas would be appreciated. Thank you.

As of Java 7 Update 21, it displays a warning message when it encounters mixed code in your signed applet.

You need to add Trusted-Only: true attribute to your manifest file so it won't show a warning dialog.

you have not made a .crt file to sign your jar with. please take a look at http://docs.oracle.com/javase/tutorial/deployment/jar/signing.html you need to make a .crt file within command prompt to use -jarsigner
