    Question regrading uploading file on Flex and reading the on Java server


      I am using Java on the server side and i am uploading a file using file reference on the client side using adobe flex 3 and passing it to the server side using http post and i am having trouble saving the file to database. I am also using hibernate, springframework, Jboss server and Mysql 5 database this is my flex code. I know for a fact that it is hitting the servlet page so i am just can't read the file.
      private function startUpload():void
      if (_arrUploadFiles.length > 0) {


      listFiles.selectedIndex = _numCurrentUpload;
      var sendVars:URLVariables = new URLVariables();
      sendVars.action = "upload";


      var request:URLRequest = new URLRequest();
      request.data = sendVars;
      request.url = _strUploadUrl;
      request.method = URLRequestMethod.POST;
      _refUploadFile = new FileReference();
      _refUploadFile = listFiles.selectedItem.file;
      _refUploadFile.addEventListener(ProgressEvent.PROGRESS, onUploadProgress);
      _refUploadFile.addEventListener(Event.COMPLETE, onUploadComplete);
      _refUploadFile.addEventListener(IOErrorEvent.IO_ERROR, onUploadIoError);
      _refUploadFile.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onUploadSecurityError);
      _refUploadFile.upload(request, "file", false);
      This is my java code and i have tried so many different ways of getting this file but have hit a brick wall and i have no other ideas
