Oracle9i JPA Hibernate NamedStoredProcedureQuery : String attributes of my object class are not matched even column names explitictly specificed

问题

As a system analyst, I develop a class object mapping the columns of tables , so that I can call stored procedures to return a list of class objects as json array. Throughout examining the SQL structure of the table, there is a composite key made of LOOKUP_CODE and LOOKUP_TYPE.

The sql database is Oracle 9i

Result : Some fields are missing to be returned

Would you please devise the strategies to match the columns under this case?

Here is my table columns :

Here is the SQL:

 CREATE TABLE "PC_LOOKUP" 
   (    "LOOKUP_TYPE" VARCHAR2(30 BYTE) NOT NULL ENABLE, 
    "LOOKUP_CODE" VARCHAR2(30 BYTE) NOT NULL ENABLE, 
    "LOOKUP_VALUE" VARCHAR2(100 BYTE) NOT NULL ENABLE, 
    "LOOKUP_DESC" VARCHAR2(200 BYTE), 
    "LAST_UPD_DATE" DATE NOT NULL ENABLE, 
    "LAST_UPD_BY" VARCHAR2(8 BYTE) NOT NULL ENABLE, 
     CONSTRAINT "B_PC_LOOKUP_PK" PRIMARY KEY ("LOOKUP_TYPE", "LOOKUP_CODE")

Here is my class (LookUp.java):

@NamedStoredProcedureQueries({

   @NamedStoredProcedureQuery(name = "call_look_up_list", 
                              procedureName = "pkg.get_pc_lookup_value",
                              parameters = {
                                 @StoredProcedureParameter(mode = ParameterMode.IN, name = "i_lookup_type", type = String.class),
                                 @StoredProcedureParameter(mode = ParameterMode.IN, name = "i_lookup_code", type = String.class),
                                 @StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, name = "o_lookup_value", type =  void.class)
                              }),

   @NamedStoredProcedureQuery(name = "call_look_up_single", 
                              procedureName = "pkg.get_pc_lookup_value_prim",
                              parameters = {
                                 @StoredProcedureParameter(mode = ParameterMode.IN, name = "i_lookup_type", type = String.class),
                                 @StoredProcedureParameter(mode = ParameterMode.IN, name = "i_lookup_code", type = String.class),
                                 @StoredProcedureParameter(mode = ParameterMode.OUT, name = "o_lookup_value", type = String.class)
                              })
})


public class LookUp implements Serializable{

    @Transient
    private static final long serialVersionUID = 3506968846904417333L;


    @Column(nullable = false , insertable = false,  updatable=false,  name = "LAST_UPD_BY" )
    private String lastUpdateBy;    

    @Column(nullable = false , insertable = false,  updatable=false, columnDefinition = "TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP" ,  name = "LAST_UPD_DATE")  
    private Date lastUpdateDate = new Date();


    @EmbeddedId
    private LookUpCompositeKey privateKey;

    @Column(nullable = true , name = "LOOKUP_DESC")
    private String desc;

    @Column(nullable = false , name = "LOOKUP_VALUE")
    private String value;

Here is my class : (LookUpCompositeKey .java)

@Embeddable
public class LookUpCompositeKey implements Serializable {

    private static final long serialVersionUID = -5628924656701586906L;


    @Column(  name = "LOOKUP_TYPE")
    String  type;

    @Column( name = "LOOKUP_CODE")
    String  code;


    public LookUpCompositeKey() {

    }
