É essa instrução que estou querendo executar:


try{  
        
        String use = user;
        char[] senh = sen;
        String s = String.valueOf(senh);
        
          String consultaUsuario = "select USUARIO,SENHA from Login where USUARIO = ? and SENHA = ? ";
         
          ConexaoPostgresql cone = new ConexaoPostgresql();              [b]O erro ocorre aqui[/b]
            pstm = cone.conecta.prepareStatement(consultaUsuario);
            pstm.setString(1,use);
            pstm.setString(2,s);
            rs = pstm.executeQuery();
            } 
           catch(SQLException e){
               e.printStackTrace();           
           } 
           
            try{  
              
            if(rs.next()){
                    
                String usuario = rs.getString("USUARIO");
                String senha = rs.getString("SENHA");
    
                }
                else{
                JOptionPane.showMessageDialog(null,"Login ou Senha Incorretos");                
             }
          } 
           catch(SQLException erro){
                    erro.printStackTrace();           
                    }                        
  }
#4

cara o erro é um NullPointerException, então dentro da classe ConexaoPostgresql()
ele está fazendo algo que ele utiliza um valor null que não foi inicializado, poem uns breakpoint e debuga la dentro
