Gwt with hibernate

Question

I need to work on hibernate and Springs along with GWT ( Google ).

This is my hibernate config file..

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
        <property name="hibernate.connection.username">root</property>

        <mapping class="com.AAA"  />

    </session-factory>
</hibernate-configuration>

And this is the model class

@Entity
public class AAA {

    @Id@GeneratedValue(strategy=GenerationType.AUTO)
    private int id;
    private String Name;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return Name;
    }
    public void setName(String name) {
        Name = name;
    }
}

this is my main class

public static void main(String arg[] ) {

    SessionFactory sessionFactory=new AnnotationConfiguration().configure().buildSessionFactory();
    Session hibernate_session = ((org.hibernate.SessionFactory) sessionFactory).openSession();
    hibernate_session.beginTransaction();

    System.out.println("Inside..");

    AAA pr = (AAA)hibernate_session.get(AAA.class,2);


    hibernate_session.getTransaction().commit();
    hibernate_session.close();

    System.out.println("Out sideee..");
}

And this is the Error getting continuously, even though there is changes of Different ver.. of `Asm.jar files.

And these are the following main jars what I am using.

asm-3.1.jar
cglib-2.1.3.jar
hibernate3
spring.jar
hibernate-jpa-2.0-api-1.0.1.final.jar

If I used these jars in Dynamic web project, every thing is fine, but in case of GWT webapplication its not..

Please give some Idea to Achieve it,
