At this place,I just want to say ant isn't so hard to study.

start to study the build.xml

#console question
1.env.CATALINA_HOME  -------------------you need to config in path
2.you will find jstl1.2 can't be used in it.----------- change it
3.```<project name="testSpring" default="war" basedir=".">```  at the first line,you can change the default,If you buid in eclipse,you can choose different way to run.In linux,you need to write it.

#console
