HIbernate Mapping Exception: PropertyNotFoundException: Could not find a setter

I have two POJO's ,STOCK and STOCK_DETAILS (one to many relationship).
Also I have one interface IAUDITLOG (having two methods). I need to implement this interface with BOTH POJO's and want to write some implementation within those methods. But when I implement IAUDITLOG interface with child class "STOCKDETAILS" then it gives exception "that you should have setter property"

STOCK CLASS:

@Entity
@Table(name = "stock")
public class Stock implements java.io.Serializable, IAuditLog
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
private Integer stockId;

@Column(name = "STOCK_CODE")
private String stockCode;

@Column(name = "STOCK_NAME")
private String stockName;

@OneToMany( fetch = FetchType.LAZY, mappedBy = "stock")
public Set<StockDetail> stockDetails = new HashSet<StockDetail>(0);


public Set<StockDetail> getStockDetails() {
return stockDetails;
}

public void setStockDetails(Set<StockDetail> stockDetails) {
this.stockDetails = stockDetails;
}

public Integer getStockId() {
return stockId;
}

public void setStockId(Integer stockId) {
this.stockId = stockId;
}

public String getStockCode() {
return stockCode;
}

public void setStockCode(String stockCode) {
this.stockCode = stockCode;
}

public String getStockName() {
return stockName;
}

public void setStockName(String stockName) {
this.stockName = stockName;
}

// overridded methods of IAUDITLOG interface
public int getLogId() {

return stockId;
}
public String getLogDetail() {
return "some implementaion";
}
}


STOCK DETAILS CLASS

@Entity
@Table(name = "StockDetail")
public class StockDetail implements Serializable, IAuditLog {
/**
*
*/
private static final long serialVersionUID = 1L;
private Integer recordId;
private Stock stock;
private Float priceOpen;


@Id
@GeneratedValue
@Column(name = "RECORD_ID", unique = true, nullable = false)
public Integer getRecordId() {
return this.recordId;
}

public void setRecordId(Integer recordId) {
this.recordId = recordId;
}

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "STOCK_ID", nullable = false)
public Stock getStock() {
return this.stock;
}

public void setStock(Stock stock) {
this.stock = stock;
}

@Column(name = "PRICE_OPEN", precision = 6)
public Float getPriceOpen() {
return this.priceOpen;
}

public void setPriceOpen(Float priceOpen) {
this.priceOpen = priceOpen;
}

//overriddded methods of IADUTILOG inteface
public int getLogId() {
// TODO Auto-generated method stub
return 0;
}

public String getLogDetail() {
// TODO Auto-generated method stub
return "some implementation";
}
}


IAUDITLOg interface:

public interface IAuditLog {
public int getLogId();
public String getLogDetail();
}

CAN ANYONE PLEASE LET ME KNOW,what could be the problem??? Why should I create getter and setter for those properties which is not ACTUALLY belongs to that class, but implemented from some other interface.
FYI... this works fine when I implement this interface with Parent class "STOCK"

Answer

You should annotate the overridden methods with @Transient.

http://docs.oracle.com/javaee/5/api/javax/persistence/Transient.html

This annotation specifies that the property or field is not persistent. It is used to annotate a property or field of an entity class, mapped superclass, or embeddable class.

P.s. As of Hibernate 3 collections are lazy by default so there is no need to explicitly mark it as lazy.
