FileItemStream não retorna nome do upload

Boa tarde galera. seguinte, estou tentando fazer um servlet de upload, como já fiz antes, porém algo não está funcionando e não consigo achar o problema…
O FileItemStream não retorna o nome do arquivo para upload.

`/**
     * Processes requests for both HTTP <code>GET</code> and <code>POST</code>
     * methods.
     *
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
     */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException
    {
        response.setContentType( "text/html" );

        boolean isMultipartContent = ServletFileUpload.isMultipartContent( request );
        if ( isMultipartContent )
        {
            FileItemFactory factory = new DiskFileItemFactory();
            ServletFileUpload upload = new ServletFileUpload( factory );
            
            try
            {
                    Article pla = null;
                    String urls = "";
                    
                    
                    FileItemIterator it = upload.getItemIterator( request );

                    while ( it.hasNext() )

                                String imagePath = ApplicationUtilities.getInstance().makeUniquePath( ApplicationUtilities.Paths.FILES, urls );

                                File filets = new File( imagePath );

                                ApplicationUtilities.getInstance().copyFile( fileItem.openStream(), filets );

                                filets.delete();
                            }
                        }

                }
                    response.sendRedirect( "/articlespane.jsp" );
            }
            catch( Exception e )
            {
                e.printStackTrace();
            }
        }
}`

Um label informa o id do arquivo e outro seleciona a imagem…
Alguém sabe o que pode estar errado?

Valeu!
