一つ質問があります。たとえば、1つのWebサイトからデータを抽出し、RDF（タートルタイプ）形式で返すプログラムをJavaで作成しました（出力はSystem.out.println()）：

The syntax is correct, because I checked it in Protege program. I read this tutorial through: http://docs.openlinksw.com/virtuoso/virtuososponger.html, but here i haven't seen how to use this cartridge in Virtuoso Sponger, where to upload .java file, I just registered cartridge, but where is no option to upload a .java file or whatever to use it.
If anyone already developed a custom Java cartridge for Virtuoso sponger, please give me link how did you include it in VS or write me how did you included it in VS. Thank you very much!
