[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Oracle sequences not being found

I'm getting validation exceptions from Hibernate during deployment of my (seam-gen generated) app, saying it can't find my sequences in Oracle, but the sequences are there.  From the log I can see it's trying qualified and unqualified names, either should be fine.

  |         @Id
  |         @SequenceGenerator(name = "analysesGenerator", sequenceName = "SEQUENCE_ANALYSES")
  | 	@GeneratedValue(strategy = SEQUENCE, generator = "analysesGenerator")
  | 	@Column(name = "ANALYSIS_ID", unique = true, nullable = false, precision = 22, scale = 0)
  | 	@NotNull
  | 	public BigDecimal getAnalysisId() {
  | 		return this.analysisId;
  | 	}

Exception during deployment:
Deployment log 
  | 09:53:32,006 INFO  [DatabaseMetadata] table not found: JANUS.SEQUENCE_ANALYSES
  | 09:53:32,009 INFO  [DatabaseMetadata] table not found: SEQUENCE_ANALYSES
  | 09:53:32,015 WARN  [ServiceController] Problem starting service persistence.units:ear=Janus.ear,unitName=Janus
  | javax.persistence.PersistenceException: org.hibernate.HibernateException: Missing sequence or table: JANUS.SEQUENCE_ANALYSES
  |         at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:698)

However the sequences are certainly there:

  | NEXTVAL                
  | ---------------------- 
  | 2

I can turn off hibernate validation, but then I get validation exceptions when I try to save a record from a form.  If I turn off sequence generation altogether (making the user enter the pk values manually), the records save just fine - but obviously users won't tolerate this.

PS: Here's another user that seems to have the identical problem, on the hibernate forums recently:

Anybody have any ideas?
