[jboss-user] [EJB 3.0] - Lazy byte array gets loaded on query

Hello, I'm trying to specify a property in my entity bean (called Appendix) as lazy loaded by the following annotations: | @Lob | @Basic(fetch = FetchType.LAZY) | @Column(name = "DOCUMENT", nullable = true) | public byte[] getDocument() { | return this.document; | } | What I want is that this property ISN'T loaded unless I access it within the scope of the entity manager. When I search for an Appendix entity bean in the database using a EJB-QL query like: | // Create traffic type query | final EntityManager theEntityManager = this.getEntityManager(); | final Query theTrafficTypeQuery = theEntityManager.createQuery("from Appendix a where a.trafficType = :trafficType"); | theTrafficTypeQuery.setParameter("trafficType", theTrafficType); | final List<Appendix> theAppendixes = theTrafficTypeQuery.getResultList(); | I can see in the JBoss log that the property "DOCUMENT" gets loaded anyway. | select appendix0_.APPENDIX_ID as APPENDIX1_0_, appendix0_.START_DATE as START2_0_, appendix0_.DESCRIPTION as DESCRIPT3_0_, appendix0_.DOCUMENT as DOCUMENT0_, appendix0_.EXTENSION_ID as EXTENSION9_0_, appendix0_.CREATE_DATE as CREATE5_0_, appendix0_.PAGE_ID as PAGE6_0_, appendix0_.PRODUCT_ID as PRODUCT7_0_, appendix0_.STOP_DATE as STOP8_0_ from APPENDIX appendix0_ where appendix0_.PRODUCT_ID=? | Does anyone know how I get my byte array property lazy loaded? If I understand it correct, loading lazy loaded entities should use the EntityManager method getReference(...), but in my case I load the entities using a query. In the following Hibernate reference docs I've read something about instrumentation, is it really necessary? http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#performanc.... I've really tried to search the forum but doesn't find anything useful. I'm using JBoss 4.0.4 GA and EJB3.0RC6.
