This class consist four Date field . All are java.utill.Date.
At the time of inserting a new object when i pass
new Date() [/b] to modifiedOn or createdOn then it is ok .
But if i pass new Date() to fromDate or todate then on insert it beacame halt. I am using MS SQl Data base .
Can any one suggest what can be the problem

what error did you get?

Are the four database columns of the same type? If not, I suspect that may be the problem. With dates you may have to be more specific than saying that it is a java.util.Date. At the database level there are usually several types of date columns. Eg. timestamp, date with no time, date with time, time only, etc.
