You can use this script to create data sources, JMS end points, and any other resources that might be needed by the application that is being deployed.
  - Post Deploy Script: This is a WLST script that is executed by Management Agent on the Administration Server after the application is deployed. You can use this script to perform any post deployment configuration. For example, if you need to roll back and undo the changes made by the pre deploy script, you can select this option.
Zip File: If you select the Upload Zip File option, you must upload a zip file that contains the JavaEEAppComp.manifest file that describes the contents of the zip file.
