Hi all.
I've upgraded to OpenEJB 3.1.1, and having an issue with mappings using OpenJPA
specific annotations, such as @Persistent to persist an InputStream as blob.
The strange part is that I was already using OpenJPA 1.2.1 with OpenEJB 3.1.0,
and without problems. If I revert to this version, everything works ok.
Previously I had the same problem when I accidentally left the openjpa-XXX.jar
file in WEB-INF/lib (thus @Persistent was defined in 2 separate classloaders,
the global and the web-app specific, which caused problems). That's not the
case now.
The exception root cause:
Caused by: <openjpa-1.2.0-r422266:683325 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Embedded property
"nl.strohalm.cyclos.entities.customization.images.Image.image" declares a
mapping override for "contents", but that is not a persistent property in the
embedded type.

The involved classes:
@MappedSuperclass
public abstract class Image extends BaseEntity {
@Embedded
@AttributeOverrides({
@AttributeOverride(name = "height", column = @Column(name =
"thumbnail_height")),
@AttributeOverride(name = "width", column = @Column(name =
"thumbnail_width")),
@AttributeOverride(name = "length", column = @Column(name =
"thumbnail_length")),
@AttributeOverride(name = "contents", column = @Column(name =
"thumbnail_contents"))
})
private ImageData thumbnail;
@Embedded
@AttributeOverrides({
@AttributeOverride(name = "height", column = @Column(name =
"image_height")),
@AttributeOverride(name = "width", column = @Column(name =
"image_width")),
@AttributeOverride(name = "length", column = @Column(name =
"image_length")),
@AttributeOverride(name = "contents", column = @Column(name =
"image_contents", columnDefinition = "mediumblob"))
})
private ImageData image;
...
}
@Embeddable
public class ImageData {
@Basic(optional = false)
private Integer height;
@Basic(optional = false)
private Integer width;
@Basic(optional = false)
private Integer length;
@Lob
@Persistent(optional = false, fetch = FetchType.LAZY)
private InputStream contents;
...
}
Can anybody help?
