EnterpriseOne Tools 8.96 currently doesn't have a facility for web users to help them identify what environment they are currently logon. Given the standard environments on a default install of DV, PY and PD, there's no easy way to automatically distinguish each from one another.
Editing the following image on the JAS would do the trick! We used the stop light colors of green, yellow and red.
LOGIN PAGE LOGO:

LOGO ABOVE THE MENU:
C:\OraHome_1\j2ee\JasOC4J\applications\jasapp\webclients\share\images\jdelogo-onwhite.gif
Now that's more like it!
