Windows系统下，redeploy过程无法删除旧项目的目录

报错信息在$TOMCAT_HOME/logs下的catalina日志文件中，如下：

信息: Undeploying context [/web-loab]  
十月 11, 2014 3:52:26 下午 org.apache.catalina.startup.ExpandWar deleteDir  
严重: [D:\tomcat\apache-tomcat-7.0.56\webapps\web-loab\WEB-INF] could not be completely deleted. The presence of the remaining files may cause problems

大概是因为Tomcat还在使用这个目录，无法删除，必须修改$TOMCAT_HOME/conf/context.xml

</Context>

也就是 在 context 标签上 添加 “antiJARLocking”， “antiResourceLocking” 属性，并都设置为 true，即可！
