Problem to get file with special characters in the message

Question

Hi, I'm developing an application that read the email and save the attached file. However, some files have special characters in the name, like: Documento de EspecificaÇÂO.doc
I noticed the de name of the file in de message head is:
"=?iso-8859-1?Q?Documento_de_Especifica=E7=E3o.doc?="
I'm already using the JavaMil 1.4.5
Tha is my code:
package br.com.cesan.helpdesk;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
import javax.mail.Flags;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Part;
import javax.mail.Session;
import javax.mail.Store;
import javax.mail.search.FlagTerm;
public class LerEmail2 {
     * @param args
     * @throws MessagingException
     * @throws IOException
     public static void main(String[] args) throws MessagingException, IOException {
          // TODO Auto-generated method stub
          // Get session
     Session session = Session.getInstance(new Properties(), null);
     // Get the store
     Store store = session.getStore("pop3");
     store.connect("pop.xxxxx.com.br", "user", "password");
     Folder folder = store.getFolder("INBOX");
          //folder.open(Folder.READ_ONLY);
          folder.open(Folder.READ_WRITE);
          // Show only unreaded Messages
          FlagTerm ft = new FlagTerm(new Flags(Flags.Flag.SEEN), false);
          // Get directory
     Message message[] = folder.getMessages();     
     //Message messages[] = folder.search(ft);
     for (int i=0, n=message.length; i<n; i++) {
          System.out.println(i + " - "+ message.getSubject() +" - " + message[i].getSentDate() );
          Object content = message[i].getContent();
          if (content instanceof Multipart) {
     handleMultipart((Multipart)content);
     } else {
     handlePart(message[i]);
     // Close connection
     folder.close(false);
     store.close();
     public static void handleMultipart(Multipart multipart) throws MessagingException, IOException {
          for (int i=0, n=multipart.getCount(); i<n; i++) {
               handlePart(multipart.getBodyPart(i));
     public static void handlePart(Part part) throws MessagingException, IOException {
          String disposition = part.getDisposition();
     String contentType = part.getContentType();
     if (disposition == null) { // When just body
          System.out.println("Null: " + contentType);
          // Check if plain
          if ((contentType.length() >= 10) && (contentType.toLowerCase().substring(0, 10).equals("text/plain"))) {
               part.writeTo(System.out);
          } else { // Don't think this will happen
               System.out.println("Other body: " + contentType);
               part.writeTo(System.out);
     } else if (disposition.equalsIgnoreCase(Part.ATTACHMENT)) {
          System.out.println("Attachment: " + part.getFileName() + " : " + contentType);
          saveFile(part.getFileName(), part.getInputStream());
     } else if (disposition.equalsIgnoreCase(Part.INLINE)) {
     System.out.println("Inline: " +
     part.getFileName() +
     " : " + contentType);
     saveFile(part.getFileName(), part.getInputStream());
     } else {  // Should never happen
     System.out.println("Other: " + disposition);
     public static void saveFile(String filename, InputStream input) throws IOException {
          if (filename == null) {
               filename = File.createTempFile("xx", ".out").getName();
          // Do no overwrite existing file
          File file = new File(filename);
          for (int i=0; file.exists(); i++) {
               file = new File(filename+i);
          System.setProperty("file.encoding", "iso-8859-1");
          FileOutputStream fos = new FileOutputStream(file);
          BufferedOutputStream bos = new BufferedOutputStream(fos);
          BufferedInputStream bis = new BufferedInputStream(input);
          int aByte;
          while ((aByte = bis.read()) != -1) {
               bos.write(aByte);
          bos.flush();
          bos.close();
          bis.close();
The problem occurs in:
FileOutputStream fos = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(fos);
BufferedInputStream bis = new BufferedInputStream(input);
int aByte;
while ((aByte = bis.read()) != -1) {
bos.write(aByte);
Thanks
