Hibernate version: The one that ships with JBoss 4.0.4.GA

The following code functions perfectly the first time through. However, if it get's hit a second time I get an error when invoking a mehtod on the actual blob ojbect.

The method element.getFrontImage(); throws an exception the second time through.

Any help is appreciated. I'm pretty much at a loss here.

Here's the Entity code:
Code:

public Class Element {
  private Blob frontImage;

...

  @Lob @Basic(fetch=FetchType.LAZY)
   public Blob getFrontImage() {
      return frontImage;
   }
}


Here's the SFSB...
Code:
  blob = element.getFrontImage();
  size = (int)blob.length();
  // fc is FileChannel
  fc.write(ByteBuffer.wrap(blob.getBytes(1, size)));



The exception:
Code:

the exception comes on the call to length...

Code:
blob.length();


with this error
Code:
ERROR: invalid large-object descriptor: 0
SQLState: 42704


pulled this info from the debugger. the previous information was from system logs. this should be more accurate.

thanks.

It's seems that the problem is a transacational issues. Specifically, stale file descriptor for the Blob object.

Originally, I was using the EM like so...
Code:
@PersistenceContext(unitName = "DC", type=PersistenceContextType.EXTENDED)
  private EntityManager em;


by moving the persistence context back to transactional like so...
Code:
@PersistenceContext(unitName = "DC")
  private EntityManager em;


The EM appears to be doing a better job of not getting stale. Here's what I would like to know. Is this the way it has to be done due to the nature of Blobs and Large Objects or is this a bug in the Hibernate Entity Manager?

I've read the Hibernate guarantees that references will not get stale. Maybe it's not a stale issues at all. Anyway, some light on this would be great.

Thanks.
