This is the method of Dao class that is throwing Exception:

I did not used any Integer here. Even the phone number property is
also a String as it can contain +,() Symbols sometimes.

public List<StudentDetails> retriveStudents( String studentFirstName, String studentLastName,String studentEmail, String studentPhoneNum) {

        logger.info("AddStudentDao retriveStudents():- START");

        List<StudentDetails> nonTerminatedStudentsList = null;

        //List<UserLocationMapping> userLocationMappings = null;

        Set<Integer> studentIdSet = new HashSet<Integer>();



        try {

            DetachedCriteria objmCriteria = DetachedCriteria.forClass(StudentDetails.class);

            //objmCriteria.createAlias("studentDetails", "UserDetails");

            objmCriteria.add(Restrictions.ne("loginId", Constants.SUPER_ADMIN));

            if (!Utilities.IsEmpty(studentFirstName)) {

                objmCriteria.add(Restrictions.like("firstName", "%" + studentFirstName + "%"));

            }

            if (!Utilities.IsEmpty(studentLastName)) {

                objmCriteria.add(Restrictions.like("lastName", "%" + studentLastName + "%"));

            }

            if (!Utilities.IsEmpty(studentEmail)) {

                objmCriteria.add(Restrictions.like("email", "%" + studentEmail + "%"));

            }

             if (!Utilities.IsEmpty((studentPhoneNum))) {

                objmCriteria.add(Restrictions.like("phoneNumber", "%" + studentPhoneNum + "%"));

            }



            nonTerminatedStudentsList = hibernateTemplate.findByCriteria(objmCriteria);//*****EXCEPTION RAISING*****(Line number 216)



            if (studentIdSet != null && studentIdSet.size() > 0) {

                nonTerminatedStudentsList = getStudents(studentIdSet);

            }



        } catch (Exception e) {

            logger.error(" AddStudentDao retriveUsers :- ", e);

        }

        logger.info("AddStudentDao retriveUsers():- END");

        return nonTerminatedStudentsList;

    }

This is supposed to return a List of StudentDetails objects but the
method used in this scenario is raising an Exception. Hope somebody
can help me.

and the exception is shown like this:

Sorry guys.. My bad.
the constant in the first Restriction is an integer.
Thank you.
