Saving attachment problem

Question

Hi, I just wrote a java code for reading mail and store the attachment on a specific folder. It works for 90%, but with some mails the system sees well that it's a multipart/mixed mail, but when I use the getDisposition() it's allways return a NULL value !!!!. I printout the getcontent and getcontenttype ... it shows the same for all mail/attcahment ... So I need help, because I can't see where the problem is. Thanks for prompt answer. here can you fina a part of the code :
for(int i=0;i<msg.length;i++)
          System.out.println("Message is: " + msg.getContentType());
if(msg[i].isMimeType("text/plain"))
System.out.println("Sender: "+msg[i].getFrom()[0]);
System.out.println("Subjet: "+msg[i].getSubject());
System.out.println("Text: "+(String)msg[i].getContent());
          try
          Connection con=null;
          Class.forName("oracle.jdbc.driver.OracleDriver");
          con=DriverManager.getConnection("jdbc:oracle:thin:@xxx","xxx","xxx");
          Statement s=con.createStatement();
          res = s.executeQuery("xxx" );
          Nbr = 0 ;
          while (res.next())
                         Address OriginalSender = msg[i].getFrom()[0];
                         System.out.println("Original Address = " + OriginalSender );
          OriginalSender2 = OriginalSender.toString();
                    } // while
               String str = (String)msg[i].getContent();
               ..... some coding
          s.close();
          con.close();
               catch(Exception e){e.printStackTrace();}
else
               if(msg[i].isMimeType("multipart/*"))
System.out.println("Sender: "+msg[i].getFrom()[0]);
System.out.println("Subjet: "+msg[i].getSubject());
/*Multipart mp = (Multipart)part.getContent();
     level++;
     int count = mp.getCount();
     for (int i = 0; i < count; i++)
//getMessageBody((Part)mp.getBodyPart(i)); //loop back into the same method
level--;*/
Multipart multipart = (Multipart)msg[i].getContent();
               System.out.println("multipart: "+ multipart);
          Part part = multipart.getBodyPart(i);
          MimeBodyPart mbp = (MimeBodyPart)part;
          System.out.println("MimeBodyPart: "+ mbp);
               System.out.println("attachment: "+ part);
               String contentType = part.getContentType();
               System.out.println("Content: "+ contentType);
               InputStream input = part.getInputStream();
               System.out.println("Input: "+ input);
               if(contentType == null)
               System.out.println("Invalid Type");
               else
               String disp = part.getDisposition();
               System.out.println("disp = " + disp);
               if(disp!=null && (disp.equalsIgnoreCase(Part.ATTACHMENT)||disp.equalsIgnoreCase(Part.INLINE)))
                    //if(contentType.startsWith("image/")){
                    String filename = part.getFileName();
                    System.out.println("filename : " + filename);
                    //InputStream input = part.getInputStream();
                    File SaveAttach = new File("C:/"+ filename);
                    FileOutputStream fos=new FileOutputStream(SaveAttach);
                    BufferedOutputStream bos=new BufferedOutputStream(fos);
                    BufferedInputStream bis=new BufferedInputStream(input);
                    int c;
                    while ((c =bis.read()) != -1)
                    bos.write(c);
                    bos.flush();
                    bos.close();
                    bis.close();
Attach = "Attach" ;
               ... coding for reply of this mail
System.out.println("End of messages");

You are right.
If I use input stream from a file I have the same problem:
<%@ page import="java.io.*" %>
<%
try{
     FileInputStream is = new FileInputStream("c:/x.jpg");
     response.setHeader("Content-Disposition", "attachment;filename=\"x.jpg\"");     
     response.setHeader("Cache-Control", "no-cache");
     response.setHeader("Pragma", "no-cache");
     int i;
     while ((i = is.read()) != -1) { out.write(i); }
     out.flush();
     out.close();
     is.close();
catch(Exception e) { }      
%>strange. do I need a special directive ?
