How do I define an entity for the following table. I've got something that isn't working and I just want to see what I'm supposed to do.

USE [BAMPI_TP_dev]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[MemberSelectedOptions](
    [OptionId] [int] NOT NULL,
[SeqNo] [smallint] IDENTITY(1,1) NOT NULL,
[OptionStatusCd] [char](1) NULL
) ON [PRIMARY]

GO
SET ANSI_PADDING OFF

This is what I have already that isn't working.

@Entity
@Table(schema="dbo", name="MemberSelectedOptions")
public class MemberSelectedOption extends BampiEntity implements Serializable {

    @Embeddable
    public static class MSOPK implements Serializable {
        private static final long serialVersionUID = 1L;

        @Column(name="OptionId")
        int optionId;

        @GeneratedValue(strategy=GenerationType.IDENTITY)
        @Column(name="SeqNo", unique=true, nullable=false)
        BigDecimal seqNo;

        //Getters and setters here...

}

    private static final long serialVersionUID = 1L;

    @EmbeddedId
    MSOPK pk = new MSOPK();

    @Column(name="OptionStatusCd")
    String optionStatusCd;

    //More Getters and setters here...
}

I get the following ST.
