Wow a stacktrace.

I would say you pass a null value to the merge function. :)

[sumaprakash]

Iam not getting you ..can u b more closure

[sumaprakash]

can u tell me more briefly

[kragoth]

Somewhere inside the code for

CalculateRateAction.calculaterate(....)

you are calling

entityManager.merge(Object entity)

The problem could be that the entity you are passing to the merge method is null.
