EJB 및 JPA 클래스 형식 오류

Question

안녕하세요, 내 웹 응용 프로그램에서 데이터베이스에 개체를 추가하려고하는데 다음과 같은 예외가 발생합니다. java.lang.ClassFormatError : 클래스 파일 Entity/Rpxfornecedor_에 중복 필드 이름 & 서명이 있습니다. 엔티티 Rpxfornecedor이 코드 :

@Entity

    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) { 
     this.fNTel = fNTel; 
    }

     return fNCel; 
    } 

    public void setFNCel(String fNCel) { 
     this.fNCel = fNCel; 
    } 

    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) { 
     this.fDataAct = fDataAct; 
    } 

    public String getFDataNAct() { 
     return fDataNAct; 
    } 

    public void setFDataNAct(String fDataNAct) { 
     this.fDataNAct = fDataNAct; 
    } 

    @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 + " ]"; 
    } 

} 

오류는 다음 코드에서 발생

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; 
    } 

그래서 어떤 조언 주시면 감사하겠습니다.

사용중인 JPA 구현은 EclipseLink 2.0입니다. 나는 jpa를 변경해 보았지만 netbeans 7.0.1과 함께 제공되는 모든 제품에서 동일한 문제가 발생했습니다.

Answer 1

마침내 데이터베이스와 엔터티의 필드 이름을 수정하여 문제를 해결했습니다. 예 :

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

이

@Column(name = "FDescricao")
