Delphi-Quellcode:

function GetMimeType(AFilename: String): JString;
var
  jstr: JString;
begin
  // MIME-Type auslesen
  result := StringToJString('application/pdf'); // Standard
  jstr := TJMimeTypeMap.JavaClass.getFileExtensionFromUrl(StringToJString(AFilename));
  if jstr <> nil then begin
    jstr := TJMimeTypeMap.JavaClass.getSingleton.getMimeTypeFromExtension(jstr);
    if jstr <> nil then
      result := jstr;
  end;
end;
