Hi I am using Hibernate 3.0 , facing issue related to the char datatype field.

I am trying to save Client pojo in the database, using following method. Problem is my client_id field is char(10) in the database. when client_id is 10 characters it works fine. but when client_id is less than ten characters it gives problem at the time of update. Rather than updating data it try to insert cleint record again and gives the unquie key exeception. i drill down the problem because of char(10) client_id field. it keeps space after client_id value upto 10 characters.

Is there is any confuguration to overcome this problem. rather than modifying client_id to varchar2.

public boolean saveClient(Clnt client) {        
        boolean lReturnValue = false;
        SessionFactory sessionFactory = null;
        Session session = null;
        Transaction transaction = null;
        try {           
            HibernateTemplate hibernateTemplate = getHibernateTemplate();
            sessionFactory = hibernateTemplate.getSessionFactory();
            session = sessionFactory.getCurrentSession();
            transaction = session.beginTransaction();
            session.saveOrUpdate(client);
            transaction.commit();
            lReturnValue = true;
        } catch (HibernateException e) {
            lReturnValue = false;
            // TODO Auto-generated catch block
            if (transaction != null) {
                transaction.rollback();
            }
            e.printStackTrace();        
        }
        return lReturnValue;

    }
