EntityNotFoundException for OneToMany Mapping

[Debasmita Dash]

Hi All,

I am working in Hibernate for the first time and am stuck with an issue.Please help me with the issue.
I want to insert records into the USER_FAVORITE_LST_T table. In the entity UserFavoriteLstEntity (for USER_FAVORITE_LST_T table) I have List<UserFavoriteClmnEntity> which corresponds to the USER_FAVORITE_CLMN_T table.
Following is the code in UserFavoriteLstEntity.

public class UserFavoriteLstEntity implements Serializable {
	@Id
	@Column(name="FAVORITE_LST_NBR")
	private long favoriteLstNbr;

	@Column(name="FAVORITE_NM")
	private String favoriteNm;

	@Column(name="USER_CD")
	private String userCd;

	@OneToMany(fetch=FetchType.LAZY, mappedBy="userFavoriteLstEntity")
	List<UserFavoriteClmnEntity> userFavoriteClmnEntityList=new ArrayList<UserFavoriteClmnEntity>();
}

Following is the UserFavoriteClmnEntity class

@Entity
@Table(name="USER_FAVORITE_CLMN_T")
public class UserFavoriteClmnEntity implements Serializable {
	@EmbeddedId
	private UserFavoriteClmnEntityPK pk;

	@Column(name="SEQ_NBR")
	private BigDecimal seqNbr;
	
    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name = "CLMN_NBR",insertable=false,updatable=false)
    private ClmnListEntity clmnListEntity;

    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name = "FAVORITE_LST_NBR", insertable=false, updatable=false)
    private UserFavoriteLstEntity userFavoriteLstEntity;
}

In the ManagerImp class I am using the following code to set the UserFavoriteClmnEntity values to the UserFavoriteLstEntity.

UserFavoriteLstEntity userFavoriteListEntity = new UserFavoriteLstEntity();
UserFavoriteClmnEntity userFavoriteColumnEntity = new UserFavoriteClmnEntity();
UserFavoriteClmnEntityPK userFavoriteColumnPKEntity = new UserFavoriteClmnEntityPK();
userFavoriteColumnEntity.setSeqNbr(sequenceNumber);				
userFavoriteColumnPKEntity.setClmnTypCd(clientPackUPCListSequence.getColumnTypeCode());
userFavoriteColumnPKEntity.setClmnNbr(columnNumber);
userFavoriteColumnPKEntity.setFavoriteLstNbr(favoriteLstNbr);
userFavoriteColumnEntity.setPk(userFavoriteColumnPKEntity);
userFavoriteColumnEntityList.add(userFavoriteColumnEntity);
userFavoriteListEntity.setUserFavoriteClmnEntityList(userFavoriteColumnEntityList);

In the DaoImpl I am using the following to insert the record into the database.

 UserFavoriteLstEntity userFavListEntity = (UserFavoriteLstEntity)super.saveOrUpdate(userFavoriteListEntity);

In the persistence.xml I have the following

<class>com.bpt.cms.services.clientpack.entity.UserFavoriteClmnEntity</class>
<class>com.bpt.cms.services.clientpack.entity.UserFavoriteLstEntity</class>
<class>com.bpt.cms.services.clientpack.entity.UserFavoriteClmnEntityPK</class>

I am able to insert record into the USER_FAVORITE_LST_T table with the above.But not able to insert records into the USER_FAVORITE_CLMN_T table it throws exception
