Hi all
I am using hibernate to upload the the news object in my project.

The code for the updating function is as follows :

public static boolean updateNews(News obj , int id) {
        Session session = null;
        Transaction tx = null;
        boolean flag  = false;
        
        try {
        	
            session = sessionFactory.openSession();
            tx = session.beginTransaction();
     
            News news = (News)session.load(News.class,new Integer(id));
            news = obj;
            String title3 = news.getTitle();
            session.update(news);
            
            tx.commit();
            flag = true;
            
        } catch(RuntimeException REx) {
            if(tx != null) {
                tx.rollback();
            }
            REx.printStackTrace();
            throw REx;
        } finally {
            session.close();
        }
      
        return flag;
    }

This function is being called in struts action by the following way :

NewsForm news = (NewsForm) form;
News bean = new News();
BeanUtils.copyProperties(bean, news);
NewsDataOperations.updateNews(bean, id)

where id is the rowid for the corresponding row to be updated.

While this function executes i get the following exception :
org.hibernate.StaleStateException: Unexpected row count: 0 expected: 1

i have tried but unable to solve it
if anybody have any idea please help me
thanx
