Estou usando uma conexao ao um arquivo do access…
Pessoal, preciso de ajuda, tenho que entegrar isso amanhã de manhã…
Código para inserir:
Código:

public void cadFuncionario(String nome,String setor,String funcao,double salario){ 
         try{ 
            stmt=conect.getStatement(); 
            stmt.executeUpdate("insert into CAD_Funcionario(NM_Funcionario,NM_Setor,NM_Funcao,VL_Salario)values('"+nome+"','"+setor+"','"+funcao+"',"+salario+")"); 
         }catch(SQLException ex){ 
            System.out.print(ex);    
         } 
         JOptionPane.showMessageDialog(null,"Registro salvo!"); 
         try { 
            stmt.close(); 
         } catch (SQLException e) { 
            e.printStackTrace(); 
         } 
      }

Código que dispara a ação:
Código:

jButton5.addActionListener(new java.awt.event.ActionListener() { 
         public void actionPerformed(java.awt.event.ActionEvent e) {    
            //Funcionario novo=new Funcionario(Integer.parseInt(jLabel1.getText()),jTextField.getText(),jTextField1.getText(),jTextField2.getText(),Double.parseDouble(jTextField3.getText())); 
            fd.cadFuncionario(jTextField.getText(),jTextField1.getText(),jTextField2.getText(),Double.parseDouble(jTextField3.getText())); 
            } 
      }); 
             
      }

Erro que aparece:
Código:

Voce prestou atencao na mensagem de erro? NullPointerException eh um dos erros mais comuns que existe.
Voce esta acessando algum objeto sem ter instanciado ele ( e a mensaem de erro indica onde isto esta ocorrendo ).
