  • 0

I am loading a value from the database, which is a Timestamp datatype in IBM DB2, but needs to be mapped as java.util.Date for the JSF GUI. I thought just tell JPA it is a timestamp and it will manage it. I did it this way:

@Temporal(TemporalType.TIMESTAMP)
@Column(name = "DATE")
private Date myTimeStampAsDate;

However if there is the Date 9999-12-31 23:59:59 in the database it will be round up in my Entity to the date 10000-01-01 00:00

If I map it as a real java.sql.Timestamp it loads even the milliseconds perfectly. What do I need to do to avoid this “rounding behavior” but keep java.util.Date for my entity and the GUI?

    Openjpa will provide a data dictionary option to not round the milliseconds for java.util.Date properties annotated with @Temporal(TemporalType.TIMESTAMP)
    . Hopefully it will come with version 2.2.1/2.3.X and ongoing. Please follow this Jira Issue to see when it will be entirely solved:

    https://issues.apache.org/jira/browse/OPENJPA-2159

    The property seems to look like this in your persistence.xml (The default will be true):

    <property name="openjpa.jdbc.DBDictionary" value="roundTimeToMillisec=false" />

    The default will be true
