Tomcat is not a web server in the way that Apache is. It is a servlet container and as such is geared to serving web applications. As such, you can't just drop files anywhere and expect things to work without a bit of structure.
Look at the other folders under webapps. Notice what they have in common?
They each have a WEB-INF sub-folder which contains a web.xml file.
This structure creates and defines an 'application context' for Tomcat to load.
So... if you want Beer-v1 to be loaded as a web app, you'll need to create a WEB-INF folder within it, and within that a minimal web.xml deployment descriptor. [ July 15, 2005: Message edited by: Bear Bibeault ]
