Repeated columns in JPA

I wanted to define repeated columns in JPA. But when I do, I got the message the second column should be defined as insert="false" , update="false"

 Approach 1: Here is an easy way to do it. In the entity bean define the second property as follows 

        @Column(name="UPLOAD_DATE")
        private Date uploadDate;
        @AttributeOverride(name="uploadDateAsTime", column = @Column
                        (name = "UPLOAD_DATE"))
        private Timestamp uploadDateAsTime;
        @Column(name="UPLOAD_STATUS")
 

 Approach 2: Here is the alternatie way to do it via XML file.. 

it would take care of giving unique names for enbeddable field columns in target entity class.

                
                
                 ddl, callback
