Pessoal, eu já não sei o que fazer. Já pesquisei em tudo quanto é lugar e não encontro uma solução.
Eu fiz uma aplicação para envio de arquivos txt.
O usuário deve clicar em um botão e o sistema deve abrir uma caixa para o usuário selecionar o arquivo txt. Para isto eu estou utilizando o JFileChooser.
Acontece que em minha máquina ela funciona perfeitamente, porém quando eu subo a aplicação para o servidor aparece o erro abaixo no log do tomcar 6.

Alguém poderia me ajudar?
Classe que seleciona o arquivo:
public String selecionarArquivoTexto() throws HandlerException{
String nome = null;
JFileChooser abrir = new JFileChooser();
abrir.setFileFilter(new FileFilter() {
@Override
public String getDescription() {
return "Diretórios e .txt"; // Exibe essa mensagem
}
@Override
public boolean accept(File arq) {
return (arq.getName().endsWith(".txt") || arq.isDirectory());
// Só mostra arquivos terminados em .txt ou diretórios
}
});
int retorno = abrir.showOpenDialog(null);
if (retorno == JFileChooser.APPROVE_OPTION) {
nome = abrir.getSelectedFile().getAbsolutePath();
}
return nome.replace("\\", "/");
}
