[jboss-user] [JBoss Seam] - Re: ERROR: invalid large-object descriptor: 0 with postgreql

Great that did the trick, thanks a  lot.

To sum up for anyone else with the same problem.

The EntityBean has
	@Lob
	public Blob getContent() 
	{
		return content;
	}
In the Stateful session bean
   @DataModel                                                                           
   private List documentList;
   
   @DataModelSelection   
   @In(required=false)
   @Out(required=false)                                                                  
   private Document document;
   
   @PersistenceContext                                              
   private EntityManager em;

//You do need to do the merge before accessing the BLOB

   em.merge(document);
Blob blob=document.getContent();
 is = blob.getBinaryStream();
