Hi,

Im trying to extend ProductImpl , in the extended class if I want to use say

List<Product> someProduct = new ArrayList<Product>;
Im getting the following exception
Use of @OneToMany or @ManyToMany targeting an unmapped class

I'm stuck with this for long time.
I saw this package org.broadleafcommerce.common.extensibility.jpa.clone and annotation interfaces within them, do i need to use any of them if i want to use the polymorphic version of the ProductObject in the extented class?
or am I wrong with the whole idea of using interface here ?

Use the targetEntity property in the JPA annotations. This is required when targeting interfaces.

Here is how the List<Sku> is annotated on ProductImpl:

Also, you do not have to target the subclassed version of ProductImpl in your targetEntity; Hibernate will inject the correct version (ProductImpl or MyProductImpl) appropriately.

hey thanks @phillipuniverse it seems to work but, since im using a field in subclassed version in mappedBy im getting following exception.

mappedBy reference an unknown target entity property: org.broadleafcommerce.core.catalog.domain.ProductImpl.stores
where as stores is in MyProdcutImpl.java

If you are mapping to a property from a subclass, then yes, you need to target the subclass itself (MyProductImpl.class).

thanks @phillipuniverse for the clarifications,It was very helpful.

I am getting ClassNotFoundException for my custom entity which I created in the core module. I have listed that class in the blPu persistence unit as well as added it to the applicationContext.xml in the core module of the site by defining
