This desktop enhancement is new in the Solaris Express 6/06 release.
Now, when a user logs into the Solaris Desktop for the first time, JavaTM Desktop System (JDS) is the default desktop environment instead of the Common Desktop Environment (CDE). JDS has also become the default environment for users who chose a desktop environment on an older Solaris release that is no longer present in the Solaris release, such as OpenWindowsTM or GNOME 2.0.
System administrators can modify the dtlogin configuration to override the default choices by using the defaultDt and fallbackDt resources.
For more information about defualtDt and fallbackDt resources, see the dtlogin(1M)man page.
