How do I assign certificates to .jar files?

To assign a certificate to a .jar file, use the jarsigner tool that is shipped along with JDK and:
  1. Set <JDK installation directory>/bin in your path.
  2. Use the generated certificate and sign the .jar. Run: jarsigner -keystore <path of the keystore> <name of the jar>.jar <certificate alias>.
  3. Enter the details for the certificate values.
  4. Repeat the process for all the .jar files in your application.
