Thanks Jacek,

Store is annotated with @Entity:

@Entity
@Table(name = "manufacturer", schema = "bidspec")
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
@NamedQueries( {
		@NamedQuery(name = "StoreFXPK", query = "SELECT s FROM Store s
WHERE s.id = :primaryKey"),
		@NamedQuery(name = "StoreFXTypeAndName", query = "SELECT s FROM
Store s WHERE s.type = :type AND UPPER(s.name) = :storeName OR
UPPER(s.displayName) = :storeName"),
		@NamedQuery(name = "StoreFXName", query = "SELECT s FROM Store s
WHERE UPPER(s.name) = :storeName OR UPPER(s.displayName) = :storeName") })
public class Store extends Persistable {
....

I thought I needed to add the class names to persistence.xml to have them
post-processed. I recognized (since using java agent right now) they are all
looked at for persistence candidacy but figured this would be needed for compile
time processing that I would switch to later. Let me know if I am way off here.
Also must I list all other classes in the <exclude-unlisted-classes> section or
can I simply list add <exclude-unlisted-classes/> after my listed classes. -
Clearly I am uncertain to the full purpose of this file

Thanks for all this support

Phill

Could you make sure that the entity behind p.store is really an entity? Is it
annotated with @Entity?

It's because you use <class> and no <exclude-unlisted-classes> in
persistence.xml. You should either remove the <class> elements or add
<exclude-unlisted-classes> and the Ignoring. warning message should go away.
