Hi Animesh,
Your realm implementation looks fine. But, JSecurity doesn't throw a
NoSuchElementException anywhere in its code. I'm assuming this has to do
with how a collection is being used, either iterated by JSecurity, or
something happening in your DAO layer.
Please include the stacktrace - it is very hard to debug without it ;)
Thanks,
Les
