Upload using O'Reilly package

[Adrian Muscalu]

Given this html form,

 
<form name="e_fileupload" method="post" enctype="multipart/form-data" action="/myWebApp/servlet/MyServlet">
<input type="file" name="filecontent">
<input type="text" name="aText" value="aaa">

,
it seems that when I try to get the value of 'aText' in the servlet returns an empty String.
My question is:
is this behaviour normal? Once the enctype is multipart/form-data I cannot send some description of the file in the same request object?
Thank you,
Adrian

hi,
you have to ask the multipart if the next part is an file or a parameter. then you put the parameter in an hashtable (or work with it directly) and the file in an uploaddirectory or something else.

this is an example to upload the file in UPLOADDIR and put the parameter in a hashtable. the hashtable is the reuturn of this method.
i hope this helps

   public Hashtable upload(HttpServletRequest request, HttpServletResponse response) throws Exception{
      Hashtable parameters = new Hashtable();
      String error         = "";
      String fileName      = "";
      // max Upload < 10MB !
      MultipartParser parser = new MultipartParser(request, 10*1024*1024);
      Part part;
      while ((part = parser.readNextPart()) != null)
      {
         String name = part.getName();
         if (part.isParam()) {
            ParamPart paramPart = (ParamPart) part;
            String value = paramPart.getStringValue();
            parameters.put(name, value);
          }
          else if (part.isFile()) {
             FilePart filePart = (FilePart) part;
             fileName = filePart.getFileName();
             if (fileName != null){
                parameters.put(filePart.getName(),fileName);
                FileOutputStream outs = null;
                try{
                    new File(UPLOADDIR).mkdirs();
                    outs = new FileOutputStream(UPLOADDIR+fileName);
                    filePart.writeTo(outs);
                    outs.flush();
                    outs.close();
               }
               catch (Exception e) {
                  error = "Failed in MultiPartRequest: " + e.getMessage();
                  System.out.println(error);
               }
            }
        }
     }
     return parameters;
   }

Thank you for your help,
the example works just fine. I've tried to save the FilePart object in the hashtable for future actions but it doesn't work. It is affected somehow and the uploaded file ends up with 0Kb.
Could this be a bug in O'Reilly's package?
Again, if I save the file into the while statement it works OK. However, it is not practical if you want to have a "conditional" upload, depending on the parameters retreieved from the same request object.
Thank you,
Adrian
