If you plan to deploy the Oracle WebLogic Server archive and Deployment Plan using the Oracle WebLogic Server administration console, you must use a specific directory structure.
The Pega Platform includes a preconfigured structure. However, if you maintain your Oracle WebLogic Server EAR files (or WAR files) in a separate location, you must replicate the proper directory structure.
For example: the directory structure for EAR file deployments is:
Plan.xmland must be located in the your_directory \plan\ directory.
