[jboss-user] [EJB 3.0] - Temporals and ON UPDATE CURRENT_TIMESTAMP

Hello there, I have an entity bean with a field "dtupdated" that I would like to have set to the current timestamp on each update of the dataset. It is annotated the following way. @Temporal(TemporalType.TIMESTAMP) @Column(columnDefinition="TIMESTAMP ON UPDATE CURRENT_TIMESTAMP") private Date dtupdated; My DB is mySQL. If I retrieve this entity bean from the DB now, make changes and write it back to the database, the dtupdated field will of course not be set to CURRENT_TIMESTAMP, because it's previous value will be explicitly passed in the UPDATE statement on the DB and CURRENT_TIMESTAMP is only set, if a NULL value is passed... How can I create a field with the desired behaviour? Any good solutions out there? Thanks a lot for your help - Dennis View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4177086#...
