How to add weblogic-application.xml in a WAR file
descriptor, jakarta-ee, java, weblogic
Solution
No, it cannot. If you do it, then it won't be considered.
It needs to be in an ear-file/META-INF
The weblogic-application.xml file is the WebLogic Server-specific deployment descriptor extension for the application.xml deployment descriptor from Sun Microsystems. This is where you configure features such as shared Java EE libraries referenced in the application and EJB caching.

Problem
Could you please let me know whether weblogic-application.xml can be added in a WAR file and if so, then how to do the same.
