I am also getting somewhat simillar error:

the error stack is below:

below is my client code:

public class Client_1

            Context jndiContext = new InitialContext(p);
            Object ref = jndiContext.lookup("TravelAgentBean/remote");
            TravelAgentRemote dao = (TravelAgentRemote)ref;

            Cabin noCabin = dao.findCabin(1);
            System.out.println("no cabin should be null: " + noCabin);

            Cabin cabin_1 = new Cabin();
            cabin_1.setId(4);
            cabin_1.setName("Master Suite");
            cabin_1.setDeckLevel(3);
            cabin_1.setShipId(3);
            cabin_1.setBedCount(3);

            dao.createCabin(cabin_1);

            Cabin cabin_2 = dao.findCabin(4);
            System.out.println(cabin_2.getName());
            System.out.println(cabin_2.getDeckLevel());
            System.out.println(cabin_2.getShipId());
            System.out.println(cabin_2.getBedCount());

	    System.out.println("Updating detached cabin instance with new bed count of 4");
	    cabin_2.setBedCount(4);  // this is where it fails
	    dao.updateCabin(cabin_2);

	    System.out.println("Finding cabin to see it has been updated with a merge() on server");
            Cabin cabin_3 = dao.findCabin(4);

        } 
        catch (Exception ne)
        {
	    ne.printStackTrace();
	}
    }

 
}


My Business Interface:

   public Cabin findCabin(int pKey) throws java.rmi.RemoteException;
   public void updateCabin(Cabin cabin) throws java.rmi.RemoteException;
   public void flushModeExample() throws java.rmi.RemoteException;

@Entity
@Table(name="CABIN")

    private String name;
    private int deckLevel;
    private int shipId;
    private int bedCount;

    @Id

	return id;
    }
    public void setId(int pk) 
    {
	id = pk;
    }

    @Column(name="CABIN_NAME")
    public String getName()
    {
        return name;
    }
    public void setName(String str)
    {
	name = str;
    }

    @Column(name="CABIN_DECK_LEVEL")
    public int getDeckLevel() 
    {
	return deckLevel;
    }
    public void setDeckLevel(int level)
    {
	deckLevel = level;
    }

	return shipId;
    }
    public void setShipId(int sid)
    {
	shipId = sid;
    }

    @Column(name="CABIN_BED_COUNT")
    public int getBedCount() 
    { 
	return bedCount; 
    }
    public void setBedCount(int bed) 
    { 
	bedCount = bed; 
    }
}



If somebody can help me out..would be a great help...

Thanks
