If you are running into the same issue after a Fresh Install or Release 12.0.x, please check the post-Installation checks logfile for the error :
...
ERROR
RW-50016: Error: - {0} was not created...

Cause

The cause has been identified as JSP- or Class-File corruption under the $COMMON_TOP/_pages.

The corruption could be a result of a wrong CLASSPATH Setting in the Environment, as the System itself was not able to access the Classes.

Solution

To implement the solution, please execute the following steps :
1. Open a new Shell and source the APPS User Environment

2. Change into the $FND_TOP Patch directory

cd $FND_TOP/patch/115/bin

3. Compile the JSP files using following command :

perl ojspCompile.pl --compile --flush -p 2

4. Initiate the execution of Autoconfig on the DB- and the APPS_Tier(s)

5. Start the APPS-Tier(s) Services again and re-test the logon
