Hi Kranthi,
Did you manipulate the index.html file? It contains the following line:
<param name="initParams" value="theme=Corbu,frameless=true"/>
If this parameter is set to true then Personas will not show its frame.
Cheers,
Tobias.
PS: I think you can overwrite this parameter for a specific session if you just add &frameless=true to your call of the index.html e.g. http://hostname:port/sap(bD1lbiZjPTEwMA==)/bc/bsp/persos/mainapp/index.html?log=debug&frameless=false
