Hi Amit,

You need to create Entity group , if you want cascading delete operation.

For clear understanding please go through this
http://code.google.com/appengine/docs/java/datastore/jdo/relationships.html#Relationships_Entity_Groups_and_Transactions

Let me know if you need more clarification.

Regards,
Kartik
