I don't have any database installed or configured for kepler. And I tried executing kepler after clearing the kepler cache. Does anybody have any idea about the possible cause of this exception and possible solution?
This  exception is blocking my work. Please let me know if there is any quick fix available.

Regards,
Madhavi
