java+jsp 实现openoffice文档在线浏览
准备工作
1.安装openoffice swftools 下载FlexPaper
openoffice官网 download full installation
http://www.openoffice.org/zh-cn/download/
swftools官网 找linux/windows对应版本
http://www.swftools.org/download.html
FlexPaper下载
https://download.****.net/download/qq_35653822/10751115
2.启动配置openoffice swftools flexpaper
安装openoffice后 去program目录下执行（每次电脑重启都要执行）
soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard
program位置在你桌面图表右键属性（我当时就找了半天）
flexpaper放到你工程可以访问静态文件的一个文件夹下
3.写代码

</html>中途遇到问题
1.jsp中flexpaper文件引入不进来 多半是FlexPaperViewer没写文件路径 或者flexpaper所在位置不是浏览器可访问路径
2.openoffice链接失败 没执行soffice那一行命令
3.不管用openoffice还是linux都访问不到生成的swf文件：没加 http://
