File saveAsOpen and Base64 encoding...

Question

In order to send the activeDocument to a web service, i need to save is as a file image, and send in an xml format.
Thus, i also need to encode it in Base64.
At this point everything is OK.
But between the saveAs of the file, its reopening, and its encoding, its corrupted.
I receive an error on the Mongrel server.
The Base64 encoder seems to work well, the rest of the code seem to be also ok, so I think my problem is either I do not save it correctly, either i do not reopen it correctly...
Please save me :(
Here is the code :
          /* STEP 1 : save current document as image file (temporary) */
          var docRef = activeDocument;
          var filepath=app.path.toString()+"/"+docRef.name+".jpg";//create the image file in the installation folder of Photoshop
          var file = new File(filepath);
          //var options = new ExportOptionsSaveForWeb();
          //options.format = SaveDocumentType.PNG;
          var options = new JPEGSaveOptions();
          options.quality=8;
          docRef.saveAs (file, options, true, Extension.LOWERCASE);
          //docRef.exportDocument (file, ExportType.SAVEFORWEB , options);
          file.close();
/* I code here dialogBox and httpCOnenction object creation
that do not need to be written here
(but if you think it's important, i can give you the full script)
          var f= new File(filepath);
          f.open();
          var buffer = f.read(f.length);
          f.close();
I build an HttpConnection object called "send"
*/                 send.request='"+f.name+""+f.length+""+base64encode(buffer)+"';
Here is the Server error :
Exception working with image: Not a JPEG file: starts with 0xc7 0xff `/var/folders/Nz/NzlixjchF+WAvFkZK9vVRU+++TM/-Tmp-/test599-0.jpg'
