Is anybody know howto map Oralce ROWID?

I has received the error message:
Column "rowid" cannot be resolved on table "LOG"

when doing mapping like this:

@Entity
public class Log implements Serializable {
	private static final long serialVersionUID = 1L;

	@Id
	private ROWID rowid;

Include the SQL and exception stack. Is this on an insert? The column must be marked as read-only (insertable/updateable=false)

In general mapping or making the ROWID the Id is not a good idea. If you really don't have an Id the either generate one, or make all of the columns the Id.

Thank you James!

It's my mistake. JPA specification doesn't support ROWID type and EclipseLink doesn't have such extension.
So, I should make the generated @Id for JPA Entity class.
