I am trying to call saveOrUpdate() in hibernate to save data. Since columns have unique index, so its throws ConstraintViolationException when I look through via Eclipse debugger.

Since root cause could be different for different exception while inserting data to table.
I wanted to know, how can I loop / traverse through getCause() to check what is the root cause of exception and its message.

Update:

Thanks.
