Information in this document applies to any platform.
Any .jar file that is not Oracle supplied jar file, requires signing with a trusted certificate from a Certificate Authority or a self signed certificate to function properly: for example, the jacob.jar file required by webutil. When configuring webutil, the jacob.jar file may be signed with the "sign_webutil.bat" or "sign_webutil.sh" courtesy script provided by Oracle. This certificate normally expires after 1 year from the date of signing.
The example given describes how to resign jacob.jar, but can be used for any custom .jar file used by an application.
