Delete using a composite-key (Spring/ Hibernate)

[DistillingSpring]

Hello,

This is a so simple operation, but I think I am little lost with some concepts.
Let's say that I have product and item and I want to delete an item like:

public void delete (Product productParam, int codeParam) {
Item it = new Item();
it.setCompositeKey(productParam);
it.setCodeX(codeParam);
}

this.getHibernatTemplate().delete(it);

Map for Item
------------
...
<many-to-one name=item class=Item> <!-- Composite key -->
<column name="code1">
<column name="code2">
</many-to-one>

I would like to do that on the programatic way instead of using the map.
Using this implementation the code1 and code 2 are null when send through the delete, even though it has value when received from the parameter.

Could you give me some clues please?

I have to confess I haven't tried to do this before. Usually you have the item you want to delete, query for it and then delete it or issue a bulk update statement to do it for you.

Hello karl, thanks for your answer. Would mind to provided me with some reference and/ or examples about what you have said?

Also, how do you have handled with this kind of situation?

Actually, there is a little correction in the map. Instead of Item it's Product
Map for Item
------------
...
<many-to-one name=product class=Product> <!-- Composite key -->
<column name="code1">
<column name="code2">
</many-to-one>


Thanks.

This is how I tend to do things like this.
