我们的下载包目录结构是与SERVLETS 2.2+ 兼容的。

你将在WEB-INF/lib 文件夹下找到若干JAR文件。 标准配置描述文件(web.xml) 在 WEB-INF/ 下，JSP文件在根目录下 （/） 大多数Servlet Engines 支持这样的 目录结构。 这样可使UploadBean的安装就像拷贝/粘贴一样。

安装步骤：

1. 把cos.jar, struts.jar 和uploadbean.jar 加入到类路径CLASSPATH中。
   (例如：把以上文件放到WEB-INF/lib/文件夹下)。
2. 拷贝 SimpleUpload.jsp, MultipleUploads.jsp, DatabaseUpload.jsp, ExceptionHandler.jsp 到web应用程序的根目录下。
   
3. 编辑 SimpleUpload.jsp 和 MultipleUploads.jsp：改变上载类型参数(文件夹, ZIP 文件...)。

4. 运行：
   文档 : http://yourserver.com/uploadbean/documentation/index.html
   例 1 : http://yourserver.com/uploadbean/SimpleUpload.jsp
   例 2 : http://yourserver.com/uploadbean/MultipleUploads.jsp
   例 3: http://yourserver.com/uploadbean/DatabaseUpload.jsp

1. 拷贝uploadbean.war 到你Servlet引擎的 Web应用程序文件夹下，这就可以了 :-)
   注意Web应用程序文件夹的名字将依赖于你的Servlet引擎，可能叫webapps/或applications/ 等等 WAR文件将被自动解压缩到uploadbean/文件夹下
   
   
2. 第一次运行：
   文档 : http://yourserver.com/uploadbean/documentation/index.html
   例 1 : http://yourserver.com/uploadbean/SimpleUpload.jsp
   例 2 : http://yourserver.com/uploadbean/MultipleUploads.jsp
   例 3: http://yourserver.com/uploadbean/DatabaseUpload.jsp
   注意UploadBean还没有 被配置。
   
   
3. 第一次运行后，停下你的引擎，根据需要编辑JSP文件， 浏览开发指南学习更多UploadBean参数。

UploadBean WAR 文件下载点击UploadBean HomePage.

• I get a 404 HTTP error when running SimpleUpload.jsp ?
  Check that ExceptionHandler.jsp file is in the same directory as SimpleUpload.jsp.
• I get JSP Exception when running SimpleUpload.jsp ?
  SimpleUpload sample stores uploaded files under a folder. If this folder doesn't exist then UploadBean will try to create one. It will fail if the servlet engine doesn't have Read/Write access. Pay attention to use / or \\ file as separator too.
• I get "uploads.zip not found" when running MultipleUploads.jsp ?
  MultipleUploads sample stores uploaded files under a ZIP archive. If this archive doesn't exist then UploadBean will try to create one. It will fail if the servlet engine doesn't have Read/Write access on this archive or on the parent folder.
• I can't upload ZIP files with MultipleUploads.jsp ?
  Check the blacklist parameter in MultipleUploads.jsp sample.
• I can't upload a big files (> 1MB) with MultipleUploads.jsp ?
  Check the filesizelimit parameter in MultipleUploads.jsp sample.
• How to get StackTrace from ExceptionHandler ?
  Right-click and view HTML source, full StackTrace is in HTML comments.
• Is there any lock for ZIP store access ?
  Yes, ZIP archive access is done through a synchronized Archiver class. There is only one instance of Archiver (singleton).
• Is there any SQL script to create table for UploadBean + database store ?
  Yes, UploadBean has been tested under Oracle8i/9i (upload_oracle.sql), IBM DB2 UDB 7.2 (upload_db2.sql) and MySQL 3.23.51 (upload_mysql.sql).
  
• DatabaseUpload.jsp returns an Exception ?
  Check that you've made modifications to <jsp:useBean ... /jsp:useBean> in DatabaseUpload.jsp that suits to your database configuration (Driver, URL, login, password). Check your JDBC driver is in CLASSPATH too.
• DatabaseUpload.jsp hangs with Oracle ?
  Check you're using LONG RAW and not BLOB in your Oracle upload table. For BLOB support try the OracleBlobDBStore add-on.
• How can I check or download a file uploaded in database ?
  We provide another 100% JAVA component : Download4J that downloads files from any folder, ZIP archive or Database.
• Should I use COS or STRUTS multipart parser ?
  UploadBean uses COS as default one but STRUTS one is really good too.
  Try this link to learn more about pros and cons of multipart parsers.
• How to add a progress bar when file is uploading ?
  You have to select Struts parser and implement your own UploadListener. You could find a ProgressStatus sample in our UploadBean add-ons section.
