Answer 1

import org.hibernate.Criteria;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;


    @Transactional
    public int changepassword(String password, long mobile) {
        // TODO Auto-generated method stub
        session = factory.getCurrentSession();
        Query query = session.createQuery("update User u set u.password='" + password + "' where u.mobile=" + mobile);
        int result = query.executeUpdate();

        return result;
    }
add this code 200% it will work... might scenario is diff but write like this:)
