Error when execute WebCenter on AdminServer

If you have created the WebCenter Portal domain and removed the managed servers, all applications were installed in AdminServer. In this case when you start your AdminServer, you will see this error:

This error happens because there is a conflict between FMW Welcome Page Application and webcenter. To solve this problem, go to WebLogic Server Console and remove the FMW Welcome Page Application.


Now, you can start the webcenter application.
