Removing Attributes on ServletContext (Application Scope) in Tomcat manually

Question

Hi Stackoverflow peeps,

I'm just wondering if there are way to remove application scope attributes in your web app. I know how to delete it in a code way, like using this:

ServletContext application = getServletConfig().getServletContext();
application.removeAttribute("sampleInfo");

But the problem is the application is currently on the production now. So, is there a way to remove it like flushing something on the server side (Tomcat), because I tried to shutdown and start the tomcat, but the attribute is still there.
