Xavier Dury commented on HHH-4261:
----------------------------------
Tested with hibernate 4.0.1
If META-INF/orm.xml is present on the classpath => org.hibernate.AnnotationException:
@Any requires an explicit @JoinColumn(s): org.hibernate.issues.any.Attachment.container
After removing META-INF/orm.xml => org.hibernate.MappingException: Foreign key
(FK1C93543ED11F13A:Attachment [container_type,container_id])) must have same number of
columns as the referenced primary key (Issue [id])
Now, I admit my setup/mapping can be incorrect due to the fact that I can't find
anything in hibernate documentation wrt to bidirectionnal associations using @Any.
I would like to implement something like:
class Attachment {
@ManyToOneAny?
@AnyMetaDef(...)
@JoinColumn
Container container;
}
class Blog implements Container {
@OneAnyToMany?(mappedBy = "container")
Set<Attachment> attachments;
}
class Issue implements Container {
@OneAnyToMany?(mappedBy = "container")
Set<Attachment> attachments;
}
I found this in hibernate doc
(http://docs.jboss.org/hibernate/annotations/3.5/reference/en/html/entity....)
@ManyToAny(metaColumn = @Column(name = "property_type"))
@AnyMetaDef(idType = "integer", metaType = "string", metaValues = {
@MetaValue(value = "S", targetEntity = StringProperty.class),
@MetaValue(value = "I", targetEntity = IntegerProperty.class)})
@JoinTable(name = "obj_properties", joinColumns = @JoinColumn(name =
"obj_id"), inverseJoinColumns = @JoinColumn(name = "property_id"))
List<Property> getGeneralProperties()
which I think is very confusing
because @ManyToOne is typically used to indicate a (* -> 1) association
and @ManyToAny is used to denote a (1 -> *) association where * could be anything
@Any mapping fails during configuration: "@Any requires an
explicit @JoinColumn(s)"

When I try to apply the @Any annotation, I get the following exception:
ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to

See the forum posting http://forum.hibernate.org/viewtopic.php?p=2403045 for another
description of this problem. That thread suggests the problem is with
EJB3OverridenAnnotationReader not adding properties annotated with @JoinColumn if xml
mapping files exist.
My code is:
@Any(metaColumn = @Column(name = "RelatedRecType"))
@AnyMetaDef(idType = "integer", metaType = "string", metaValues =
{
@MetaValue(targetEntity = Approval.class, value = "approval"),
@MetaValue(targetEntity = ZoningPermit.class, value =
"zoningpermit") })
@JoinColumn(name = "RelatedRecNum", nullable = false)
public BlueserveEntity getNoteOwner()
{
return this.noteOwner;
}
An orm.xml file (auto-generated by seam-gen) exists in this project, though it has no
entity mappings and there are no other hbm.xml files. When I remove this file, I no
longer receive the exception (that's not a long-term solution).
