Cannot Un-deploy a web-app completely in Tomcat

Hi,

I have been using Maven for deploy and redeploy to Tomcat, and it was great cause you don't need always to do it manually.
But in Windows environment I have encounter an issue that is "I cannot undeploy the web application completely from the Tomcat".
I have found a solution and its easy:

Open context.xml from /tomcat/conf folder and modify the context to match this :

<Context antiJARLocking="true" antiResourceLocking="true">
