SOS problem using one Entity bean for editing records. please help me

Question

Hello
I have one great problem using one entity bean 2.1 and i am working with this problem several days and i dont solve it.
i am using this jb 2.1 for add new records to one oracle database and for editing records.
I have one great problem for editing records
I have one objets that is as one of my database table. (PersonaObj.java)
     //personaObj.java
     public class PersonaObj implements Serializable{
          private Integer id_persona; //this ishte database table autonumeric
          private java.lang.String nombre;
          now the set/get methods.
     One field of this objets (bean) is the primary key of the table, and this field is one part of the pk from the entity bean.
     From one session bean i call the entity bena passing the objet
     into the entity bean (interface) i have one methods:
          public getPersona getT56aaat04();
     public void setPersona(PersonaObj obj);
     into the entitybean bean i have:
     public PersonaEntityPK ejbCreate(PersonaObj obj) throws CreateException {
          this.setT56aaat04(obj);
          public abstract Integer getId_persona();
     public abstract void setId_persona(Integer Id_persona);
     public abstract java.lang.String getNombre();
     public abstract void setNombre(java.lang.String Nombre);
     public PersonaObj getPersona() {
          PersonaObj obj = new PersonaObj();
          obj.setId_persona(getId_persona());
          obj.setNombre(getNombre());
          return obj;
     public void setPersona(PersonaObj obj) {
          setId_persona(obj.getId_persona());
          setNombre(obj.getNombre());
But i have one graet problem.
adding new record to the database i runs well but if i want to edit one recor appears this error:
=> Error <=
java.rmi.RemoteException: EJB Exception: ; nested exception is: javax.ejb.EJBException: EJB Exception: : java.lang.IllegalStateException:[EJB:010144]The setXXX method for a primary key field may only be called during ejbCreate.

into the session bean i make this (the session recibes one PersonaObj obj):
T56aContactosEntityLocal personaLocal ;
               try {
                    personaLocal = personaHome.findByPrimaryKey(new T56aContactosEntityPK(obj.getId_a04()));
                    T56aaat04Obj objTmp = new T56aaat04Obj();
                    objTmp.setAp1_a04(obj.getAp1_a04());
                    objTmp.setEstado_a04("false");
                    personaLocal.setT56aaat04(obj);
Please can you help me to solve this problem?

Hello Werner,
The mappings seem to be alright at a first glance.
Have you tried out un- and redeploying your application? Sometimes values appear to be cached in the server. So if you have deployed the application before you entered DB_BANK as alias this might solve the problem...
