测试环境：
tomcat-6.0.14
ubuntu gusty
sun-jdk-1.6
多个人合作的项目里只要修改tomcat-conf.properties文件后即可使用。我这里用了slf4j做LOG，不用LOG的把相关类去掉即可。还有我是把tomcat/lib下的jar都加进classpath的。

tomcat-conf.properties:
catalina.home=/home/jarod/server/tomcat/apache-tomcat-6.0.14
为什么要
setCatalinaHome?
设了该值，tomcat启动时会在该目录加载默认的一些配置，如MIME mapping等，如果要自己手动添加配置太麻烦了，而如果不要这些配置，这个embedded tomcat用处也不大
