I have an issue related to sequence not found when I upgrade hibernate from 3.5 to 4.0.0.RC6:
at org.hibernate.internal.SessionImpl.persist(SessionImpl.java:
I found the answer.
For common id generator for all classes, we should use
@Id @GeneratedValue(generator="GENERATOR_COMMON") @GenericGenerator(name="GENERATOR_COMMON",strategy="point.to.table.generator")
Hope this help someone who have the same issue like me.
