A project is using Sferyx in Webforms, and the file HTMLEditorLight.jar is used. But ‘copy and paste’ from outside the form to the editor is not working. Cause: the jar-file need to be signed. To sign a jar-file the tools ‘keytool’ and ‘jarsigner’ is needed. But… why not use a script from e.g. webutil:  sign_webutil.sh? With a few adjustments it’s a quite common, usable script.

Below is the script. In bold the variables which you need to adjust. Beware of the different paths for ‘keytool’ / ‘jarsigner’ !

#   NAME
#      sign_jar.sh – Sample script to sign jar-files
#   USAGE
#      sign_jar.sh <jar_file>
#      jar_file : Path of the jar file to be signed. Prefer to use forward
#                 slash instead of back-slash. Otherwise, some characters may
#                 be strangely escaped. e.g. \f may be printed as ‘female’
#                 symbol character on some systems.
#   NOTES
#      This script uses keytool and jarsigner utilities, which usually comes
#      along with JDK in its bin directory. These two utilities must be
#      available in the PATH for this script to work. Otherwise, signing
#      will fail even though the script may show a successful signing.
#
# The following are the Distinguished Names for keytool. You can change them
# to generate your own key.
# CN = Common Name
# OU = Organization Unit
# O  = Organization
# C  = Country code
#
# Certificate settings:
# These are used to generate the initial signing certificate
# Change them to suite your organisation
#
DN_CN=”Example Firm”
DN_OU=”Development Tools”
DN_O=Mydomain
DN_C=nl
#
# Give your keystore file
KEYSTORE=/home/oracle/dba/key/.keystore
#
# If KEYSTORE already exists, old KEYSTORE_PASSWORD for the keystore file must
# be correctly given here. If KEYSTORE does not already exist, any password
# given here will be taken for the new KEYSTORE file to be created.
#
KEYSTORE_PASSWORD=<keystore_passw>
#
# Give your alias key here.
#
JAR_KEY=<app_name>
#
# Key Password for the given key to be used for signing.
#
JAR_KEY_PASSWORD=<file_passw>
#
# Number of days before this certificate expires
#
VALIDDAYS=360

#
# Signing script starts here…
