我用jboss和jb9做了個簡單的實體bean，釋出沒問題
執行客戶段時，丟擲下列異常：
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.ServerException: EJBException:; nested exception is:
javax.ejb.EJBException: Internal error setting instance field productID; CausedByException is:

主鍵類程式碼為：
package helloworld;

import java.io.Serializable;
public class ProductPK implements Serializable{
public String productID;
public ProductPK(String productID) {
this.productID = productID;
}
public String toString(){
return productID.toString();
}
public int hashCode(){
return productID.hashCode();
}
public boolean equals(Object prod){
return ((ProductPK)prod).productID.equals(productID);
}

}
