CMP exception: Attempt to cast instance "xxx [java.lang.String]" to PersistenceCapable failed. Ensure that it has been enhanced.

Hi

i've been playing around with a test project consisting of

a cmp entity bean and a simple 1-method-webservice trying to persist on
instance of that entity.

deployment of the classes went well but i couldnt get an entity-instance
persisted.


the entity class look something like this

@Entity
@Table(name="SOMETABLE")
public class EntityClass implements Serializable
{
        @Id
        @GeneratedValue(strategy=GenerationType.AUTO)
        public int id;
        @Column(length=100)
        public String name;
        
        int getId()
        {
                return id;
        }
        
        void setId(int id)
        {
                this.id = id;
        }
        
        String getName()
        {
                return name;
        }
        
        void setName(String name)
        {
                this.name = name;
        }
}


whereas the webservice implementation is

@Stateless
@WebService(serviceName = "TestWS",
            portName = "TestWSPort",
            endpointInterface = "xxxx",
            targetNamespace = "xxx")
public class TestWSBean implements TestWS {
        
        @PersistenceContext(unitName="TestPU")
        private EntityManager em;

        public String saveName(String value)
        {
                String result = "ok";
                
                try {
                        EntityClass b = new EntityClass();
                        b.setName(value);
                        em.persist(value);      
                }
                catch(Exception ex) {
                        ex.printStackTrace();
                        result = ex.getLocalizedMessage() + " " + 
ex.getClass().getName();      
                }
                
                return result;
        }
}


Calling the webservice-method from within the eclipse ws-explorer i get the
following message:



Attempt to cast instance "abc [java.lang.String]" to PersistenceCapable
failed.  Ensure that it has been enhanced.
org.apache.openjpa.persistence.ArgumentException
 
geronimo is 2.1.3.

Kind regards
