It works quite well, but it is not a speed champion. I used it like this

ServletDataSource sds = new ServletDataSource(req, resp);
msg = new MimeMultipart(sds);
int parts = msg.getCount();

.....

class ServletDataSource implements DataSource
{
   private String cType = "";
   private OutputStream os;
   private InputStream is;
   private int len = -1;

   ServletDataSource(HttpServletRequest in, HttpServletResponse out)
            throws IOException
   {
        os = out.getOutputStream();
        is = in.getInputStream();
        len = in.getContentLength();
        cType = in.getContentType();
   }

   public InputStream getInputStream()
            throws IOException
   {
        return is;
   }

   public OutputStream getOutputStream() 
   {
        return os;
   }

   public String getContentType() 
   {
        return cType;
   }

   public String getName() 
   {
        return "dummy";
   }
}
