Good day

I've got a problem in a project that I'm developing and I'm becoming crazy :|
I'm using jboss5.1 with ejb3, hibernate and postgres8.4. I've created a stupid table called 'ships' because I want to test what happens when a table hasn't got a primary key.
My entity bean is:
Code:
@Entity
@Table(name="ships")
@IdClass(JokerId.class)
public class Ship implements Serializable {

   private static final long serialVersionUID = 3612308018537637948L;
   
   @Column(name="ship_type")
   private String shipType;
   
   @Column(name="ship_name")
   private String shipName;
   
   @Column(name="staff_number")
   private Integer staffNumber;
   
   @Column(name="commander_name")
   private String commanderName;
   
   public Ship() {
      super();
   }

   public Ship(String shipType, String shipName, Integer staffNumber, String commanderName) {
      
      super();
      this.shipType = shipType;
      this.shipName = shipName;
      this.staffNumber = staffNumber;
      this.commanderName = commanderName;
      
   }

   public String getShipType() {
      return shipType;
   }

   public void setShipType(String shipType) {
      this.shipType = shipType;
   }

   public String getShipName() {
      return shipName;
   }

   public void setShipName(String shipName) {
      this.shipName = shipName;
   }

   public Integer getStaffNumber() {
      return staffNumber;
   }

   public void setStaffNumber(Integer staffNumber) {
      this.staffNumber = staffNumber;
   }

   public String getCommanderName() {
      return commanderName;
   }

   public void setCommanderName(String commanderName) {
      this.commanderName = commanderName;
   }
   
}

class JokerId implements Serializable {

   private static final long serialVersionUID = 6679333070251022160L;
   String shipType;
   String shipName;   
   
}


I've used the @idclass to specify a combination of id. But when I try to execute a stupid query via entity manager I get this error:

I used a similar entity class in another project and it worked fine. Can you give me a help, please?

Thanks a lot
