EJBとJPAクラスのフォーマットエラー

Question

こんにちは、私のWebアプリケーションでデータベースにオブジェクトを追加しようとしていて、次の例外が発生します。java.lang.ClassFormatError：クラスファイルEntity/Rpxfornecedor_の重複フィールド名&。エンティティRpxfornecedorのこのコード：

@Entity 
@Table(name = "rpxfornecedor") 
@XmlRootElement 
@NamedQueries({ 
    @NamedQuery(name = "Rpxfornecedor.findAll", query = "SELECT r FROM Rpxfornecedor r"),

    @NamedQuery(name = "Rpxfornecedor.findByFDescri\u00e7\u00e3o", query = "SELECT r FROM Rpxfornecedor r WHERE r.fDescri\u00e7\u00e3o = :fDescri\u00e7\u00e3o"), 
    @NamedQuery(name = "Rpxfornecedor.findByFNTel", query = "SELECT r FROM Rpxfornecedor r WHERE r.fNTel = :fNTel"), 
    @NamedQuery(name = "Rpxfornecedor.findByFNCel", query = "SELECT r FROM Rpxfornecedor r WHERE r.fNCel = :fNCel"), 
    @NamedQuery(name = "Rpxfornecedor.findByFEndere\u00e7o", query = "SELECT r FROM Rpxfornecedor r WHERE r.fEndere\u00e7o = :fEndere\u00e7o"),

    public Rpxfornecedor() { 
    } 

    public Rpxfornecedor(String fid) { 
     this.fid = fid; 
    } 

    public Rpxfornecedor(String fid, String fDataAct) { 
     this.fid = fid; 
     this.fDataAct = fDataAct; 
    } 

    public String getFid() { 
     return fid; 
    } 

    public void setFid(String fid) { 
     this.fid = fid; 
    } 

    public String getFNome() { 
     return fNome; 
    } 

    public void setFNome(String fNome) { 
     this.fNome = fNome; 
    } 

    public String getFDescrição() { 
     return fDescrição; 
    } 

    public void setFDescrição(String fDescrição) { 
     this.fDescrição = fDescrição; 
    } 

    public String getFNTel() { 
     return fNTel; 
    } 

    public void setFNTel(String fNTel) {

    public String getFEndereço() { 
     return fEndereço; 
    } 

    public void setFEndereço(String fEndereço) { 
     this.fEndereço = fEndereço; 
    } 

    public String getFEmail() { 
     return fEmail; 
    } 

    public void setFEmail(String fEmail) { 
     this.fEmail = fEmail; 
    } 

    public String getFFax() { 
     return fFax; 
    } 

    public void setFFax(String fFax) { 
     this.fFax = fFax; 
    } 

    public Character getFActivo() { 
     return fActivo; 
    } 

    public void setFActivo(Character fActivo) { 
     this.fActivo = fActivo; 
    } 

    public String getFDataAct() { 
     return fDataAct; 
    } 

    public void setFDataAct(String fDataAct) {

    } 

    @Override 
    public int hashCode() { 
     int hash = 0; 
     hash += (fid != null ? fid.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 Rpxfornecedor)) { 
      return false; 
     } 
     Rpxfornecedor other = (Rpxfornecedor) object; 
     if ((this.fid == null && other.fid != null) || (this.fid != null && !this.fid.equals(other.fid))) { 
      return false; 
     } 
     return true; 
    } 

    @Override 
    public String toString() { 
     return "Entity.Rpxfornecedor[ fid=" + fid + " ]"; 
    } 

} 

エラー、次のコードで発生します。

public Rpxfornecedor addfornecedor(String Id, String nome, String endereço, String email, String cell, String tel, String fax, String des, String dnow){ 
    Rpxfornecedor Forn = new Rpxfornecedor(); 


    //em.flush(); 
    Forn.setFid(Id); 
    Forn.setFNome(nome); 
    Forn.setFEndereço(endereço); 
    Forn.setFEmail(email); 
    Forn.setFNCel(cell); 
    Forn.setFNTel(tel); 
    Forn.setFFax(fax); 
    Forn.setFDescrição(des); 
    Forn.setFActivo('Y'); 
    Forn.setFDataAct(dnow); 
    Forn.setFDataNAct("fbedfdf");  

    if(Forn != null){ 
     em.persist(Forn); 
     //em.persist(Forn);  
    } 


    return Forn; 
    } 

だから、何かアドバイスが理解されるだろうしてください。

私が使用しているJPAの実装はEclipseLink 2.0です。私はjpaを変更しようとしましたが、netbeans 7.0.1に付属しているすべてのものに同じ問題があります。

Answer 1

私は最終的にそれを修正するためにデータベースとエンティティのフィールドの名前を変更しました。例：

@Column(name = "FDescri\u00e7\u00e3o") 

あなたはJPAの実装を使用している

@Column(name = "FDescricao")
