There does not seem to be an easy way to do this. Please log an enhancement request and vote for it.|
You can use a native SQL query for this. You will need to set "eclipselink.maintain-cache"="true" on the query.
You could also map a separate class to the historical table, and include the start and end date in the object, and the startDate as part of the Id. This is really what you would want to do, as querying the original class will not give you access to the start and end dates. You could use a MappedSuperclass and have the current and historical class subclass it and use the different tables.
