Description
According to Java bean standard the setter for attribute qMgrId is setQMgrId. But for some reason Hibernate fails to find the setter and i get the above mentioned exception.
However when i change the value of the name attibute of the id element in the Mapping XML document to QMgrId('q' in capital) then everything works fine.
