There are two issues here, and neither is critical but misleading to the new uPortal 3 users.

First, the README file in the root of the project structure incorrectly describes the location of the log4j.properties file. The README says that the file is in /uportal-war/src/main/resources/log4j.properties, but it is actually in /uportal-war/src/main/webapp/WEB-INF/log4j.properties.

Second, the header of the file has not been modified from the time it used to be Logger.properties in uP 2.x resulting in further misleading about the location of the file. The location of the file after deployment is simply in uPortal/WEB-INF.
