项目需要一个在线浏览文档的功能，于是参照网上的代码写了一份利用Microsoft Office 2010和swftools-2013-04-09-1007.exe转换的程序
思路：调用电脑本机的office组件把ppt或者word转换为pdf文件，接着调用pdf2swf应用把pdf文件转换为swf。

但由于目前项目组没有windows的服务器，于是想着试试能不能搭一个在linux上能跑的程序。首先尝试过最新的OpenOffice4，程序虽然能跑，但是却仍然无法支持数学公式的转换，于是转而使用LibreOffice，完美地解决了问题，以下为记录linux环境下的配置过程。

0 环境
Java: "1.7.0_79"
OS: ubuntu-15.10-server-i386.iso
libreoffice: LibreOffice_5.0.6.3_Linux_x86_deb
swftools:swftools-0.9.2.tar.gz
1. ubuntu安装libreoffice
从LibreOffice官网下载安装包LibreOffice_5.0.6_Linux_x86_deb.tar.gz并上传到ubuntu上，运行命令
tar -zxvf LibreOffice_5..6_Linux_x86_deb.tar.gz
sudo dpkg -i ./LibreOffice_5.0.6.3_Linux_x86_deb/DEBS/*.deb
最终的安装目录为 /opt/libreoffice5.0
2. ubuntu安装SWFTools
从swftools下载swftools-0.9.2.tar.gz并上传到ubuntu上，运行命令
sudo apt-get install g++
sudo apt-get install libgif-dev xpdf libfreetype6 libfreetype6-dev libjpeg62 libjpeg8 libjpeg8-dev
tar -zxvf swftools-0.9..tar.gz
cd swftools-0.9./
./configure
make
sudo make install
sudo apt-get install xpdf
3. 打包转换代码并上传
https://github.com/hivsuper/converter
4. 编写启动脚本
#! /bin/sh
export JAVA_HOME=/opt/java/jdk1.
export PATH=/opt/java/jdk1./bin
java -jar converter-0.0.-SNAPSHOT.jar
遇到的问题：
a. 安装swftools时遇到`./configure`命令运行报错，最终发现是由于没有安装g++导致
b. 由于服务器系统为server版，故默认无桌面，虽然程序在windows系统跑没有问题，但一直报错
org.artofsolving.jodconverter.office.OfficeException: could not establish connection
最后安装了桌面程序再次运行，问题解决
sudo apt-get install ubuntu-desktop
c. 运行启动脚本发现一直报错，内容如下：
