Looks like you are trying to use a null object in your DAO. Of course without seeing the code I can't be sure.

Hi Paul Sturrock
this error came while i was trying to insert a value to the table named Item,
my DAO code is given bellow

public class userDAO extends HibernateDaoSupport{
private Item item;
public void setItem(Item item)
{ this.item = item;
System.out.println("<<<<item.getDescription()1>>>");
System.out.println(item.getDescription());
}

public void findGroupByName(String name) {
getHibernateTemplate().save(item);
}
public void saveitem()
{
System.out.println("item.getDescription()200");

System.out.println(getHibernateTemplate());
getHibernateTemplate().save(item);
}

}

here i am getting the item(from POJO) values which i am passing from a jsp page.
but getHibernateTemplate() is returning a null value.
please tell me if u know the solution
