<%
        try {
            // Apache Commons-Fileupload library classes
            DiskFileItemFactory factory = new DiskFileItemFactory();
            ServletFileUpload sfu  = new ServletFileUpload(factory);

            if (! ServletFileUpload.isMultipartContent(request)) {
                System.out.println("sorry. No file uploaded");
                return;
            }

            // parse request
            List items = sfu.parseRequest(request);
            FileItem  PartNo = (FileItem) items.get(0);
            String photoid =  PartNo.getString();

            FileItem SerialNo = (FileItem) items.get(1);
            String phototitle = SerialNo.getString();

            // get uploaded file
            FileItem file = (FileItem) items.get(2);

            // Connect to Oracle
            Class.forName("oracle.jdbc.driver.OracleDriver");
            Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "hr", "hr");
            con.setAutoCommit(false);

            PreparedStatement ps = con.prepareStatement("insert into InventoryDB_Main(PartNo,SerialNo) values(?,?)");
            ps.setString(1, photoid);
            ps.setString(2, phototitle);
            // size must be converted to int otherwise it results in error
            ps.setBinaryStream(3, file.getInputStream(), (int) file.getSize());
            ps.executeUpdate();
            con.commit();
            con.close();
            out.println("File Uploaded Successfully.");
        }
        catch(Exception ex) {
            out.println( "Error --> " + ex.getMessage());
        }

%>

This is my code which is not working it throws error, index 1, size 1.
