Why would I want to unpack my WAR file?
* WAR files are sometimes more difficult to undeploy, and have problems such as not being able to determine the application root, it is sometimes preferable to unpack the WAR file.
* Some packages such as JSPWiki have the properties files in the WAR, so it must be unpacked to edit settings before deployment.
How to unpack
* Rename the file as a zip file (eg: myapp.war becomes myapp.zip)
* Unzip as you would with any other zip file
