JFileUpload 適合很多涉及到Web 上傳的公司如印刷公司、主機(jī)服務(wù)、攝影師、網(wǎng)站管理員、CMS 商家、web相冊(cè)等。JFileUpload 是一個(gè)Java 應(yīng)用程序（Applet和WebStart），它允許終端用戶向web 或ftp 服務(wù)器上傳文件和文件夾。它可以被整合到任何應(yīng)用程序中。
快速輕松的部署。

• 進(jìn)度條：JFileUpload 前端包括一個(gè)進(jìn)度條，在任何時(shí)候都可以通過(guò)取消按鈕停止上傳。
• 文件選擇和拖拽：終端用戶可以通過(guò)一個(gè)對(duì)話框或直接簡(jiǎn)單的從文件系統(tǒng)資源管理器中拖拽即可選擇文件。支持多文件和多目錄選擇，同時(shí)可以壓縮子目錄。
• 自定義：JFileUpload 支持多語(yǔ)言，前端資源（菜單、文本、消息、背景圖片、外觀等）以ASCII 格式存儲(chǔ)，并且可以修改。也可以添加圖片預(yù)覽器，同時(shí)顏色也可以更改。
• 高級(jí)特性：JFileUpload 支持超大文件上傳（高達(dá)2GB），同時(shí)客戶端占用較少的資源（內(nèi)存、CPU）。它可以恢復(fù)被中斷的上傳，上傳前重命名文件以及快速壓縮文件。它可以限制上傳文件大小（以bytes為單位）或限制上傳文件類型（比如*.doc, *.exe）。它允許上傳額外的參數(shù)（如：登錄名，密碼，sessionid,cookie），并且允許在上傳后進(jìn)行重定向。
• 跨服務(wù)器端技術(shù)：JFileUpload 是一個(gè)客戶端組件，它支持HTTP 和FTP 傳輸協(xié)議。在服務(wù)端你需要一個(gè)服務(wù)器端組件來(lái)處理上傳：
  HTTP: JFileUpload 通過(guò)標(biāo)準(zhǔn)的HTTP 協(xié)議（RFC1867）向Web 服務(wù)器發(fā)送文件，這就是為什么服務(wù)器端技術(shù)可以是Java/J2EE™,PHP,Microsoft ASP/.NET,Macromedia/Coldfusion 或 Perl/CGI的原因。針對(duì)Java/J2EE 服務(wù)器端腳本我們推薦使用JSPUpload 來(lái)處理在文件夾或數(shù)據(jù)庫(kù)中的文件上傳和存儲(chǔ)。另外也支持HTTPS（HTTP在SSL之上）。
  FTP：被認(rèn)證后（匿名或用戶賬號(hào)）JFileUpload 可以向ftp 服務(wù)器發(fā)送文件。另外也支持FTPS（FTP在SSL之上）
• 跨瀏覽器：JFileUpload 可以在大多數(shù)的操作系統(tǒng)下工作，如Windows,Linux,MacOSX.它已經(jīng)通過(guò)Internet Explorer, Safari, Firefox, Opera 以及Google Chrome 的測(cè)試。
• 靈活的API：JFileUpload API 非常的靈活。它整合了新的前端、嵌入自定義過(guò)濾器、傳遞額外的HTTP 參數(shù)、支持cookies和session,代理服務(wù)器，支持認(rèn)證。但是這些特性只能在JFileUpload 企業(yè)版和附加包中可用。
• 插件：一些其他的產(chǎn)品可在JFileUpload 上工作：
  JBatchUpload 上傳前添加隊(duì)列文件
  類似于FTP 的上傳、下載資源管理器Amazon Simple Storage Service (S3)上傳文件管理器
  支持安全的FTPFlickr 上傳圖片預(yù)覽器和圖片過(guò)濾器，快速生成縮略圖，為你節(jié)省了帶寬和上傳時(shí)間。
  還可以使用工具插件，如PHP,JSP,ASP.NET和ColdFusion簡(jiǎn)單上傳腳本，PGP 加密過(guò)濾器、JavaScript API.更多的工具可以嵌入到JFileUpload 中。

JFileUpload fits to many businesses involving web uploads such photographers, printing companies, web albums, hosting services, webmasters, CMS vendors ... JFileUpload is a Java Application (Applet and WebStart) that allows end-user to upload files and folders to a web or ftp server. It could be integrated into any application. Deployment is fast and easy.

• Progress bar:JFileUpload front-end includes a progress bar. Upload could be stopped at any time thanks to a cancel button.
• File(s) selection and Drag&Drop:End-user could select file(s) to upload with a dialog box or through simple drag and drop from file system explorer. Multiple files and directories selection is allowed. Recurse subdirectories feature is available too.
• Customization:JFileUpload includes multilanguage support. Front-end resources (menu, text items, messages, background image, look and feel, ...) are stored in ascii files and could be modified. Image previewer could be added and colors could be modified too.
• Advanced features:JFileUpload supports very large uploads (more than 2 GB) with low resources (RAM, CPU) usage on client-side. It could resume broken upload, rename files before upload and ZIP file on fly. It allows to limit size (in bytes) or type (e.g. *.doc, *.exe) of files to upload. It allows to pass extra parameters (e.g. login, password, sessionid, cookie, ...) and allows post-processing by redirecting to an URL after upload.
• Cross server-side technology:JFileUpload is a client-side component. It provides both HTTP and FTP transport protocols support. You do need a server-side component to process upload on server:HTTP: JFileUpload sends files to a web server through standard HTTP multipart (RFC 1867) request, that's the reason why server-side technology could be Java/J2EE™, PHP, Microsoft ASP/.NET, Macromedia/Coldfusion or Perl/CGI. For Java/J2EE server-side script, we recommend JSPUpload to process upload and store files in folder or database. Note that HTTPS (HTTP over SSL) is supported too.
• FTP:JFileUpload sends files to a ftp server after being authenticated (anonymous or user account). Note that FTPS (FTP over SSL) is supported too.
• Cross browsers:JFileUpload works under most operating systems such as Windows, Linux and MacOSX. It has been tested with Internet Explorer, Safari, Firefox, Opera and Google Chrome.
• Flexible API:JFileUpload API is flexible. It is designed to integrate new front-ends, plug custom filter, pass extra HTTP parameters, support cookies and session, proxies, support authentication ... However, this feature is only available in JFileUpload enterprise and premium packages.
• Add-ons:A few others products could work on the top of JFileUpload: JBatchUpload to queue files before upload, FTP-like explorer to upload and download, Amazon Simple Storage Service (S3) uploader and file manager, Secure FTP support, Flickr upload, image previewer and image scaling filter to generate thumbnails on the fly. Such filter allows saving bandwidth and lowering upload time. An add-ons section is available with tools such as PHP, JSP, ASP.NET and ColdFusion upload sample scripts, PGP encryption filter, JavaScript API and more tools that could be plugged to JFileUpload.
