Java Cast Exception

[Aslam]

Hello,

I have a problem with a findByPrimaryKey method which I have in my

Data Access Object File. The method returns a java List and I am casting

to a list in my code but I get java.lang.ClassCastException. ANY idea why the exception could be occurring? - many thanks.

List heldPrice = (List)

super.getHandle().findByPrimaryKey(item.getComposi te_id);

The handle is fine and composite_id passed appears to have been built correctly. It is made up of three fields.

The composite_id was set using the setter method for it on the Item object.

Item is a DB Table and has a object representation as Item with itemDAO being the data access mapping file.

the itemDAO has the following method:

public final List findByPrimayKey(final ItemPK itemPK)
throws finderDAOException{

Object [] ObjectArray = ( itemPK.getItem(),
itemPK.getItemDate,
itemPK.getSource()};
Type[] Array = { Hibernate.BIG_DECIMAL,

Hibernate.BIG_DECIMAL,

Hibernate.String};

return get HibernateTemplate().find(
" from Item item where item.composite_id.item = ?" +
" and item.composite_id.itemDate =?" +
" and item.composite_id.itemSource =?",
ogbjectArry,
typrArray);
}
}
}

Aslam,

Have you checked the error output to see what class it the compiler says you are trying to cast what class? You might you've accidentally imported a different List class. There should be no problem casting from java.util.List to java.util.List.

Hi,

You are right. Someone changed the DAO object and the casting needed changng from List to aspecif user class!

Thanks.
