Hi!
Habe versucht mit einem injezierten EntityManager (@PersistenceContext...)
mit der Methode persist() ein Blob in die Datenbank zu speichern. Bekomm
aber immer wieder folgende Exception:

java.lang.RuntimeException: org.jboss.tm.JBossRollbackException: Unable to commit, tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=susi-linux/12194, BranchQual=, localId=12194] status=STATUS_NO_TRANSACTION; - nested throwable: (javax.persistence.PersistenceException: java.lang.IllegalStateException: Blobs may not be accessed after serialization)

Warum geht das nicht? Bitte dringend um Hilfe!
