Problema dll Delphi com jna

djJoe · Julho 5, 2013, 9:15am

Olá amigos, estou tendo problemas com uma dll em java, em Delphi ela funciona beleza, mas, meus conhecimentos em Delphi são muitos limitados, por isso resolvi criar essa Dll e usar com java. Acredito que o problema seja com os tipos Variant e OleVariant, pois testei uma simples MessageBox e funcionou.

Código da Dll.


library MacroParaJava;


uses
  SysUtils,
  ComObj,
  windows,
  Variants,
  Classes;

   var
   Sess0,
   Sistema,
   Sessions: OleVariant;


//______________________________________________________________________________

                          // Conectar ao STC

 procedure conectarSTC;  stdcall;
    begin

  Sistema := CreateOleObject('EXTRA.System');
  Sessions:= Sistema.Sessions;
  Sess0   := Sistema.ActiveSession ;
  MessageBoxA(0,PAnsiChar('Criado Sessão!'),PAnsiChar('Aviso'),0);
    
    end;
//______________________________________________________________________________


       // Mover para uma posição na tela conforme argumentos informados
 procedure Mover(linha, coluna:Integer); stdcall;
    begin

  Sess0.Screen.MoveTo (linha, coluna);

    end;
//______________________________________________________________________________

                      // Tempo entre uma tela

 procedure aguardar; stdcall;
    begin

   while(Sess0.Screen.OIA.XStatus = 5) do
   begin
   end;
    end;

//______________________________________________________________________________

            // Enviar uma tecla conforme argumento informado

procedure enviarTecla(tecla:String); stdcall;
    begin
 Sess0.Screen.SendKeys(tecla);
    end;

//______________________________________________________________________________

                   // Copiar uma área da Tela

 function copiarAreaTela(linhaDe, colunaDe,linhaAte,colunaAte:Integer): String;  stdcall;
  begin

    Result:= Sess0.Screen.Area(linhaDe,colunaDe,linhaAte,colunaAte);
  end;


//______________________________________________________________________________

                   // Desconectar

 procedure desconectarSTC;  stdcall;
  begin
    Sess0    :=Unassigned;
    Sessions :=Unassigned;
    Sistema  :=Unassigned;
  end;



                    // Exportar Funções e Procedimentos
Exports
test,
conectarSTC,
Mover,
aguardar,
enviarTecla,
desconectarSTC,
copiarAreaTela;

begin
end.

Interface JNA com apenas um método para teste.


import com.sun.jna.Library;


public interface InterfaceJna extends Library{   
    
    
    public void conectarSTC();
  
}

Código da classe onde é chamado.


InterfaceJna ij = (InterfaceJna) Native.loadLibrary("MacroParaJava.dll", InterfaceJna.class);
   
    ij.conectarSTC();
