[Komari raj]

Hi,

I have deployed pluto-1.1.4 and the pluto portal is working fine.
Now i am not able to deploy a portlet on the pluto portal.
Even when i deploy the Portlet War file, then also i am not able to select the ADD Portlet button on the pluto portal.

Can anybody tell me what si wrong with it.
Incase of any doubt, kindly let me know.

Error
ErroPluto_Error.txtr rendering portlet.
