ORDS Create Deploy WAR

create_deploy_war.py

#!/usr/bin/python
#
# Python code to create a new ords.war that can be deployed to a supported Apache Tomcat or WebLogic Server container.
# The created web archive is based on the ords.war distribution but has the following modification:
# - The META-INF files are not copied.
# - The web.xml has the configutation directory explicitly set. Setting the config.url environment variable is not required.
#
# Usage: create_deploy_war <source ords.war> <destination war filename> <configuration directory>
