> The OpenJPA manual very briefly talks about the @VersionColumns annotation, but its usage is not clear. I have an entity that tries to use this annotation (below), but I get back an exception when I run the mapping tool against it:
> "Exception in thread "main" <openjpa-1.3.0-SNAPSHOT-runknown fatal user error>
> org.apache.openjpa.util.MetaDataException: For "entities.Employee<version>", expected 1 column(s),
> but found 2."
> @Entity
> @VersionColumns({@VersionColumn(name="vcol1"),@VersionColumn(name="vcol2")})
> @SecondaryTable(name="EADDRESS", pkJoinColumns=@PrimaryKeyJoinColumn(name="EMPID"))
> public class Employee {
>         @Id @GeneratedValue(strategy=GenerationType.AUTO)
>         private int empid;
>         private String name;
>        
>         @Column(table="EADDRESS")
>         private String street1;
>         @Column(table="EADDRESS")
>         private String street2;
>         @Column(table="EADDRESS")
>         private String city;
>         @Column(table="EADDRESS")
>         private int zipcode;
> }
