My project features the following configuration:
I use static weaving to lazily fetch heavy relations (done by load groups).
I have the following entity to serialize and store files to the database:
@Entity
@Table(name = "Document")
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
public class Document implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE)
protected Long id;
@Column(length = 128)
protected String description;
@Lob
@Basic(optional=false, fetch=FetchType.LAZY)
protected byte[] content;
@Transient
protected transient File file;
public Document() { }
// getters and setters ...
}
The following is a coutout from my document facade that contains the management functions (persist, modify, remove and queries) :
@Override
@RolesAllowed("User")
public Document queryById(Long id, LoadGroup group) {
TypedQuery<Document> query = em.createQuery("SELECT d FROM Document d WHERE d.id = "+id, Document.class);
if(group!=null) {
query.setHint(QueryHints.LOAD_GROUP, group);
}
try {
return query.getSingleResult();
} catch(NoResultException ex) {
return null;
}
}
This is how I invoke the query on the stand-alone client:
DocumentFacadeRemote documentFacade = (DocumentFacadeRemote)ctx.lookup("java:global/LawSuiteEE/LawSuiteEE-ejb/DocumentFacade!ch.lawsuite.control.DocumentFacadeRemote");
LoadGroup group = new LoadGroup();
group.addAttribute("content");
Document document = documentFacade.queryById(new Long(1), group);
Now I get the following exception:
Exception Description: The parameter name [ID] in the query's selection criteria does not match any parameter name defined in the query.
and here's the full stack-trace:

Any help highly appreciated! Many thanks in advance!
I changed
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
to
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
and now it works just fine. It somehow had a conflict with the inherited @Id's. JPA used a auto-generated fetch group of the sub-class even when calling the query on a object instance of the super class... Probably a bug in eclipse-link.
