Hi,

Most of j2ee application servers (tomcat, jboss) when a war or ear
file is deployed. It will generate a folder which contains the same
file structure (web application format) as which is in the war or ear
file.

A war is considered as a file but not a path. So if Tomcat only reads
war but not a directory based content, it has problem (when changes to
parent path, or changes to child path). Besides, a war is a packed jar
file, reading a directory based content is a lot more easier and
faster than a packed jar file.
