Repeated column in mapping for entity ERROR PLEASE HELP..

[Abduljaleel Ch]

This is my entity configurations..

@Entity
  @Table(name = "VSS_FILE_HEADER")
  public class PatchVO implements Serializable{
   
   @Id
   @GeneratedValue(strategy=GenerationType.SEQUENCE,generator="my_entity_seq_gen")
   @SequenceGenerator(name="my_entity_seq_gen", sequenceName="VSS_FILE_HEADER_SEQ")
   @Column(name="VSS_ID")
   private Long vssId;
   @Column(name="FILE_NAME")
   private String fileName;
   
   @OneToMany(cascade=CascadeType.ALL)
   @JoinColumn(name = "VSS_ID",insertable=false,updatable=false,nullable=false)
   private List <VssArtifactVO> vssArtifacts;

--------------------------------------------------------------------
@Entity
@Table(name = "VSS_ARTIFACTS")
public class VssArtifactVO implements Serializable {
   
   @EmbeddedId
   private CompoundKey id;
   
   @Transient
   private Long artifactSeq;
    

   @Embeddable   
   public static class CompoundKey implements Serializable{
            
        @Column(name="VSS_ID")
        private Long vssId;
        @Column(name="ART_TYPE_ID")
        private Integer artifactTypeId;
        @Column(name="ARTIFACT_NAME")
        private String artifactName;
        public CompoundKey() {}
        public CompoundKey(Long vssId,Integer artifactTypeId,String artifactName) {
           this.vssId=vssId;
           this.artifactTypeId=artifactTypeId;
           this.artifactName=artifactName;
        }
          
   }

}

But i am getting the following error
Repeated column in mapping for entity: om.gov.moh.phs.patch.vo.VssArtifactVO column: VSS_ID (should be mapped with insert="false" update="false");

How can I solve this issue?.. I cannot give VSS_ID as insertable=false,updatable=false because this is a composit key in VssArtifactVO ..
Please help...

Thanks in Advance
