关闭启动tomcat
在发布war文件的时候经常需要关闭启动tomcat，太麻烦了，就起了怎么在ant里实现一体化的想法在google了一下以后找到了答案，经过验证是可行的
一、失败的解决方案，不够好
通常的想法是写一个target来实行，可是这个样子好像不太来晒艾，ant会堵塞在那里一直到tomcat挂了为止.
执行以下的ant target，你只能得到以下的结果，永远得不到"END STARTUP TOMCAT 4.1"，除非tomcat结束了
STARTUP TOMCAT 4.1
Using CATALINA_BASE: C:/Tomcat4.1
Using CATALINA_HOME: C:/Tomcat4.1
Using CATALINA_TMPDIR: C:/Tomcat4.1\temp
Using JAVA_HOME: C:/j2sdk1.4.2_02
二、有个强人给了一个解决办法，自写tomcat的任务
