You'll find more CAs with a simple Google search.

Keep in mind, even though this is a Java JAR, the dialog you're seeing is from Windows complaining about the EXE being unsigned. You'll need a MS Authenticode signing certificate to sign the EXE. I'm not too familiar with Java, so you may or may not need a certificate to sign the JAR as well. (Note a self-signed certificate will never be recognized as fully Trusted and Valid on any computer other than your own.)
