[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - facing issues in persisting standalone application using hib

[gup123]

Hi I am new to this area and I am using hibernate3.2, hibernate-annotation3.2 and hibernate-entitymanager3.2 for persisting a object in the database in  a standalone program i.e.  plain java, but i am getting the following program when i run.

Please suggest any solution or if i am missing anything: exception is =:

Code is some thing like this:
/**
 * AB generated by hbm2java
 */
@Entity
@Table(name="ABs"
    ,schema="Cat"
, uniqueConstraints = {  }
)

public class ABs  implements java.io.Serializable {
    // Fields
     private NId id;
     private Cdates cdates;
    // Constructors
    /** default constructor */
    public ABs() {    }

    /** full constructor */
    public ABs(NId id, Cdates cdates) {
        this.id = id;
        this.cdates = cdates;    }
    // Property accessors
    @EmbeddedId
    @AttributeOverrides( {
        @AttributeOverride(name="A",...))
        @AttributeOverride(name="B", ...) ) } )

    public NId getId() { return this.id;    }
    
    public void setId(NId id) { this.id = id;   }
    @ManyToOne(cascade={},
        fetch=FetchType.LAZY)    
        @JoinColumn(name="A", unique=false, nullable=false, insertable=false, updatable=false)

......
}

another class
/**
 * NId generated by hbm2java
 */
@Embeddable

public class NId  implements java.io.Serializable {
    // Fields    
     private String a;
     private String b;
    // Constructors

    /** default constructor */
    public NId() {
    }
    
    /** full constructor */
    public NId(String a, String b) {
        this.a = a;
        this.b = b;
    }
   
    // Property accessors
    @Column(name="a", unique=false, nullable=false, insertable=true, updatable=true, length=200)

    public String getA() {   return this.a;    }
    
    public void setA(String a) { this.a = a;  }
    @Column(name="B", unique=false, nullable=false, insertable=true, updatable=true, length=30)

    public String getB() { return this.b;   }
    
    public void setB(String b) {  this.b = b;   }
    
    public boolean equals(Object other){.....}
    public int hashCode() {....)
}

and the main class is 
public class SSTest {
	public static void main(String[] arg)
	{
		SSTest sstest = new SSTest();
		sstest.addNS();
	}

	public void addNS()
	{
	     EntityManagerFactory emf = Persistence.createEntityManagerFactory("manager1");
	     NId item = new NId( "111111", "111111" );

	     ABs ns = new ABs();
	         ns.setId(item);

          EntityManager em = emf.createEntityManager();
			em.getTransaction().begin();
			em.persist( ns );
			em.getTransaction().commit();
     }// end of method
}// End of Class
