Answer 1

Maybe you could try to change the values in your sign_webutil.bat file:
REM Give your alias key here.
REM
SET JAR_KEY=webutil3
REM
REM Key Password for the given key to be used for signing.
REM
SET JAR_KEY_PASSWORD=webutil3
REM
REM Number of days before this certificate expires
REM
SET VALIDDAYS=360
