[Jdeveloper 12c] Récupérer les données d'une view à travers un bean

Bonjour. J'ai un object view entet base sur plusieurs tables dont le code

Code:

import oracle.adf.share.ADFContext;
 
import oracle.dfw.impl.common.SecurityContext;
 
import oracle.jbo.server.ViewObjectImpl;
// ---------------------------------------------------------------------

public class EnteteImpl extends ViewObjectImpl {
    /**
     * This is the default constructor (do not remove).
     */
    public EnteteImpl() {
    }
 
    /**
     * Returns the bind variable value for p_user.
     * @return bind variable value for p_user
     */
    public String getp_user() {
        //return (String) getNamedWhereClauseParam("p_user");
        //We want this bind variable to return user name from the security context:
        //SecurityContext securityContext = ADFContext.getCurrent().getSecurityContext();
        //String userName = securityContext.gestUserName();
        String _currentUser = ADFContext.getCurrent().getSecurityContext().getUserName(); 
        return _currentUser;
    }
 
    /**
     * Sets <code>value</code> for bind variable p_user.
     * @param value value to bind as p_user
     */
    public void setp_user(String value) {
        setNamedWhereClauseParam("p_user", value);
    }
}

Et je veux à travers une classe java accéder aux attributs:

Code:

1
2
3
4
5
6

    public void findData(){
        ViewObject view = (ViewObject) Utilities.getApplicationModule().findViewObject("Entete1"); 
        view.setNamedWhereClauseParam("p_user",Utilities.getCurrentUser());  
        view.executeQuery();
        //Row row = view.first();
        EnteteImpl row = (EnteteImpl)view.first();
        this._username = (String)row.getAttribute(arg0)
    }

Le code mis en gras ne m'affiche uniquement getp_user() alors que dans la vue j'ai des champs comme poste,service, etc.. auquel je veux accéder
Merci
