45. Date/Timestamp problem with Java: equals fails, workarounds? forum.hibernate.orgThe dateEquals option is the best of what you suggest.

51. Is there unsaved-value="" equivalent in JPA annota forum.hibernate.orgProbably No. Identifier mappings The unsaved-value attribute is now optional, in most cases. Hibernate will use unsaved-value="0" as the default, where that is sensible. Note: In Hibernate3, it is no longer necessary to implement Interceptor.isUnsaved() when using natural keys (assigned identifiers or composite identifiers) and detached objects. In the absence of any "hints", Hibernate will query the database to determine if ... |
