como podem ver, fiz o codigo em jigloo, mas eu quero uma coisa, tem os dois botoes ai, eu queria que quando o usuario clicasse nele, pudesse escolher diretorio, nao o arquivo, mas sim o diretorio. tentei usar o jFileChooser, mas como o nome ja diz, ele so pega o arquivo.
E alem disso eu tbm n conseguia executar ele, nem sabia como pegar o arquivo encontrado, o botao do fileChooser de cancelar tb m n funcionava, alguem poderia me explicar esses detalhes
