How do I undeploy/completely-remove .war deployed under webapps directory when Tomcat 6.x is uninstalled?

Question

Does anyone know of a method to remove all webapps deployed from .war files when uninstalling Tomcat (other then Shift + Delete . . .)? The reason I ask is is described below.

I am using InstallShield 2009 to lay down a copy of the JRE and Tomcat 6.x, where the Tomcat start/stop uses org.apache.catalina.startup.Bootstrap and is registered as a Windows service with a custom name. When the "program" is uninstalled certain directories need to be left behind, such as log files.

There is also behavior in place, where Installshield does not remove directories or files that it did not install. For example InstallShield has a reference to <filename>.war, but not the expanded contents into <filename>/<files> and <filename>/<directories> when Tomcat is installed and the WAR file is extracted.

Answer 1

The method of complete removal of Tomcat and .WAR files used to satisfy InstallShield2009 was to (via InstallShield2009):

1. Remove the .WAR file
2. Restart the Tomcat service
3. The deployed exploded directories from the .WAR file have already been removed, or are now removed.
4. Stop the Tomcat service.
5. Remove Tomcat.

If anyone out there knows of a way via command-line switch or something to tell Tomcat to remove all, or specific directories under /webapps/ then please respond, otherwise I'm going to accept the steps above as the answer.
