First, the deployment rules concerning appBase, docBase, <Context>,
etc., have changed significantly between 4.1 and 5.5. The current rules
are much more strict, and certain errors in older Tomcat versions that
may have resulted in acceptable behavior but went against the spec have
been corrected.
The appBase attribute of the <Host> element specifies the default
directory under which apps are deployed. However, no app or portion
thereof (e.g., a .jsp, .html, .css) may be placed directly in the
docBase directory, unless the app is packaged in a .war file. By
default, appBase is set to CATALINA_HOME/webapps; if you examine this
directory on a clean Tomcat installation, you will note that it contains
nothing other than subdirectories, since the sample apps that come with
Tomcat are expanded, not deployed as .war files.
Apps normally are placed in subdirectories (or .war files) under
appBase; the name of the subdirectory (or .war file) is the URI path to
the app. The one exception to this is the default app, which must be in
the webapps/ROOT subdirectory (or webapps/ROOT.war file).
When an app is deployed under appBase, its <Context> element should
appear in the META-INF/context.xml file of the app, and should not
contain either a path or docBase attribute. Alternatively, the
<Context> element may be placed in a file called [appname].xml within
conf/[engine]/[host] (by default, conf/Catalina/localhost). Such a
<Context> should not contain a path attribute, and should only use a
docBase attribute if the app is deployed in a location other than under
the appBase directory. Finally, the <Context> element may appear inside
a <Host> element in server.xml (for compatibility with 4.1), but that
practice is strongly discouraged, since it requires a restart of Tomcat
to make any changes. In this last case, the <Context> element must
specify both path and docBase attributes.
