Actually, that's exactly the procedure that can cause the problem.  When the 
webapp is first loaded, Tomcat copies the webapp's META-INF/context.xml file to 
conf/Catalina/[host]/[appName].xml.  As long as the 
conf/Catalina/[host]/[appName].xml file exists, it will override the one in 
META-INF/context.xml.  Proper undeployment will remove the copied <Context> 
element; just copying over a new version of the webapp will not.
