WAS 7.0 app will not start inside RAD 7.5

PROBLEM:

The following error message appears when a J2EE app is attempted for deployment-
A composition unit with name  already exists. Select a different application name.

RESOLUTION:

Delete the /blas and /cus directories for the bad application from the configuration.
The resources will be located in the config directory of the profile.:

/config/cells/qcell/blas
/config/cells/qcell/cus 

See the following URL for more details:

Once the above directories are deleted, add projects to WAS Server inside RAD and then publish the application.
