autoUnpackWars (Tomcat)

AutoUnpackWars is a feature of Tomcat which automatically unpacks WAR files before deployment, creating all the files and folders that are stored in the WAR file.

This is useful for a number of reasons:

• An unpacked application is less likely to be locked by Tomcat, allowing it to be undeployed more easily.
• Unpacked applications are able to write to their Application Root and other folders such as WEB-INF, because the folders exist in the file system. When the application is deployed as a WAR file, these folders don't exist.
• Class and jar files exist in the file system, which is accessed faster than a WAR file.
