In the adminConsole , when we click on the tree nodes , Common Tasks, Domain, Server etc, the Page Title displayed on the Left Top corner of the browser has the Logo "Sun" before the tree node name .
It shows up for all the tree nodes in the left tree.
and also appears before the URL http://hostname:4848

Notice the Sun Logo before "Common Tasks", and also in the URL field.
