inviare richiesta alla sevlet

[n1o]

Ciao a tutti ragazzi allora il mio rpblema è il seguente, so che è una domanda stupida:
da un form devo fare una ricerca e mi deve restituire i dati presenti nel db

ma al momento che vado a cliccare mi da questo errore:

at session.DivxFacade.findByTitolo(DivxFacade.java:51) 

Il form è:

<div id="container_box">
      

 Ricerca un film:</p>
           <form action="Find" id="tit_divx" method="post">
              <input type="text">
              <input type="submit" value="Cerca">
           </form>
</div> 

Il codice nella servlet è:

 Divx idDisp = (Divx) controllerDao.findByTitolo();
            request.getParameter("tit_divx");
                if(idDisp != null) {
                    request.getRequestDispatcher("//lista_aggr_cod_disp.jsp").forward(request, response);
                } else {
                    request.getRequestDispatcher("/error.jsp").forward(request, response);
                } 

che richiama il controller

public List findByTitolo() {
        return divxFacade.findByTitolo();
    } 

Il session interessato è:

    public List<Divx> findByTitolo(){
        return em.createQuery("SELECT d FROM Divx d WHERE d.titolo = :titolo").getResultList();
    } 

E l'entity interessato è:

@Entity
@Table(name = "divx")
@NamedQueries({
    @NamedQuery(name = "Divx.findAll", query = "SELECT d FROM Divx d"),
    @NamedQuery(name = "Divx.findByIddivx", query = "SELECT d FROM Divx d WHERE d.iddivx = :iddivx"),
    @NamedQuery(name = "Divx.findByCoddivx", query = "SELECT d FROM Divx d WHERE d.coddivx = :coddivx"),
    @NamedQuery(name = "Divx.findByTitolo", query = "SELECT d FROM Divx d WHERE d.titolo = :titolo"),
    @NamedQuery(name = "Divx.findByAnno", query = "SELECT d FROM Divx d WHERE d.anno = :anno"),
    @NamedQuery(name = "Divx.findByTipoSupporto", query = "SELECT d FROM Divx d WHERE d.tipoSupporto = :tipoSupporto")})
public class Divx implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "Id_divx")
    private Integer iddivx;
    @Basic(optional = false)
    @Column(name = "Cod_divx")
    private String coddivx;
    @Basic(optional = false)
    @Column(name = "Titolo")
    private String titolo;
    @Column(name = "Anno")
    @Temporal(TemporalType.DATE)
    private Date anno;
    @Lob
    @Column(name = "Trama")
    private String trama;
    @Basic(optional = false)
    @Column(name = "TipoSupporto")
    private String tipoSupporto;
    @JoinColumn(name = "Id_genere", referencedColumnName = "Id_genere")
    @ManyToOne
    private Genere idgenere;

    public Divx() {
    }

    public Divx(Integer iddivx) {
        this.iddivx = iddivx;
    }

    public Divx(Integer iddivx, String coddivx, String titolo, String tipoSupporto) {
        this.iddivx = iddivx;
        this.coddivx = coddivx;
        this.titolo = titolo;
        this.tipoSupporto = tipoSupporto;
    }

    // METODI SETTER E GETTER

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (iddivx != null ? iddivx.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof Divx)) {
            return false;
        }
        Divx other = (Divx) object;
        if ((this.iddivx == null && other.iddivx != null) || (this.iddivx != null && !this.iddivx.equals(other.iddivx))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "entities.Divx[iddivx=" + iddivx + "]";
    }

} 

Dove sbaglio?
grazie mille a tutti per l'aiuto siete fantastici

[n1o]

allora ho fatto un po di cambiamenti:

La servlet ora è:

public class Find extends HttpServlet {
    @EJB
    private ControllerDaoLocal controllerDao;
    
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            Divx idDisp = new Divx();
            String titolo = request.getParameter("titolo");

            idDisp.setTitolo(titolo);
            idDisp = (Divx) controllerDao.findByTitolo();

            if(idDisp != null) {
            request.getRequestDispatcher("/lista_aggr_cod_disp.jsp").forward(request, response);
            } else {
            request.getRequestDispatcher("/error.jsp").forward(request, response);
            }

        } finally { 
            out.close();
        }
    } 

Il controller è:

@Stateless
public class ControllerDao implements ControllerDaoLocal {
    @EJB
    private AttoreFacadeLocal attoreFacade;
    @EJB
    private DivxFacadeLocal divxFacade;

    public List findAllDivx() {
        return divxFacade.findAll();
    }

    public List findAllAttore() {
        return attoreFacade.findAll();
    }

    public Divx divxById() {
        return divxFacade.find(this);
    }
    /* QUESTO E' IL METODO */
    public List findByTitolo() {
        return (List) divxFacade.findByTitolo("titolo");
    } 

Il session è:

@Stateless
public class DivxFacade implements DivxFacadeLocal {
    @PersistenceContext(unitName = "Applicativo3-ejbPU")
    private EntityManager em;

    public void create(Divx divx) {
        em.persist(divx);
    }

    public void edit(Divx divx) {
        em.merge(divx);
    }

    public void remove(Divx divx) {
        em.remove(em.merge(divx));
    }

    public Divx find(Object id) {
        return em.find(Divx.class, id);
    }

    public List<Divx> findAll() {
        return em.createQuery("select object(o) from Divx as o").getResultList();
    }

    /*public Divx findByTitolo(Object titolo) {
    return em.find(Divx.class, titolo);
    }*/
    public List<Divx> findRange(int[] range) {
    Query q = em.createQuery("select object(o) from Divx as o");
    q.setMaxResults(range[1] - range[0]);
    q.setFirstResult(range[0]);
    return q.getResultList();
    }
/* QUESTO E' IL METODO */
    public List<Divx> findByTitolo(String titolo){
    Query q = em.createQuery("SELECT d FROM Divx d WHERE d.titolo = :titolo");
    q.setParameter(titolo, q);
    return (List<Divx>) q;
    }
    public int count() {
        return ((Long) em.createQuery("select count(o) from Divx as o").getSingleResult()).intValue();
    }
} 

per il resto è tutto rimasto invariato ma adesso mi da questo errore:

Mi è saltata all'occhio questa riga:

Caused by: java.lang.IllegalArgumentException: You have attempted to set a value of type class oracle.toplink.essentials.internal.ejb.cmp3.EJBQueryImpl for parameter titolo with expected type of class java.lang.String from query string SELECT d FROM Divx d WHERE d.titolo = :titolo. 

Praticamente mi dice che gli passo un oggetto Divx e che gli devo passare una String

Come faccio?
Dove sbaglio?
vi prego aiutoooo

[R@ve M@ster]

Dove sbaglio?

Qui:

Query q = em.createQuery("SELECT d FROM Divx d WHERE d.titolo = :titolo");
q.setParameter(titolo, q); 

Va sostituito con:

q.setParameter("titolo", titolo);

Ciao R@ve preciso come sempre grazie mille.
Devo sostituire entrambe le righe che mi hai detto(anche quella contenente anche la query vera e propria) con quella che mi hai scritto?
Grazie mille mi state aiutando tantissimo

Ovviamente no! Se togli la prima riga, la variabile q nella seconda non sarebbe definita!

Infatti la domanda era più stupida del solito, adesso ho un altro problemuccio (Vi sto tartassando vi ringrazio per la vostra infinita disponibilità)

Con la modifica del codice non mi lancia più nessuna eccezione ma non mi richiama più nessuna pagina(cioè mi restituisce lo schermo bianco) e non capisco perchè.
Il codice nella servlet è:

 try {
            Divx coDisp = new Divx();
            
            coDisp = (VRicercaAggrCodDispaccio) controllerDao.findByCodeDivx();
                coDisp.setCode("codeDivx");
            request.setAttribute("code", coDivx);
                if(coDivx != null) {
                    request.getRequestDispatcher("/lista_aggr_cod_Divx.jsp").forward(request, response);
                } else {
                    request.getRequestDispatcher("/error.jsp").forward(request, response);
                }
        } finally { 
            out.close();
        } 

e nella jsp me lo riprendo in questo modo:

<table id="table_listMazzetti">
                                <tr id="tr_testata">
                                    <td id="td_indice"> Codice </td>
                                    <td id="td_testata"> Sigla Video </td>
                                    <td id="td_testata"> Frazionario </td>
                                    <td id="td_date"> Status </td>
                                    <td id="td_testata"> Data di Creazione </td>
                                    <td id="td_testata"> Data di Check </td>
                                    <td id="td_testata"> Data di Scan </td>
                                    <td id="td_testata"> Nome </td>
                                    </tr>
                                        <%
                                        Divx coDivx= (Divx)request.getAttribute("code");
                                        %>

                                <tr id="tr_collection">
                                    <td id="td_collection"> <%= coDivx.getCode() %></td>
                                    <td id="td_collection"> <%= coDivx.getSiglavideo() %></td>
                                    <td id="td_collection"> <%= coDivx.getFrazionario() %></td>
                                    <td id="td_collection"> <%= coDivx.getStatus() %></td>
                                    <td id="td_collection"> <%= coDivx.getCreationDate() %></td>
                                    <td id="td_collection"> <%= coDivx.getCheckDate() %></td>
                                    <td id="td_collection"> <%= coDivx.getScanDate() %></td>
                                    <td id="td_collection"> <%= coDivx.getName() %></td>
                                </tr>
                           </table> 

è giusto o no?
Le pagine jsp sono nel path giusto
grazie mille ragazzi siete fantastici
