Which XHTML files do I need to put in /WEB-INF and which not?

Solution 1:

Files in /WEB-INF folder are indeed not publicly accessible by enduser. So you cannot have something like http://localhost:8080/contextname/WEB-INF/some.xhtml. That would be a potential security hole as the enduser would be able to view among others /WEB-INF/web.xml and so on.

You can however use the /WEB-INF folder to put master template files, include files and tag files in. For example, the following template client page.xhtml which is placed outside /WEB-INF and is accessible by http://localhost:8080/contextname/page.xhtml:

<ui:composition template="/WEB-INF/templates/template.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets"
>
    <ui:define name="content">
        ...
        <ui:include src="/WEB-INF/includes/include.xhtml" />
        ...
    </ui:define>
</ui:composition>

The advantage of placing master templates and include files in /WEB-INF is that the enduser won't be able to open them directly by entering/guessing its URL in the browser addres bar. The normal pages and template clients which are intented to be accessed directly must not be placed in /WEB-INF folder.

By the way, the composite component files are in turn also not supposed to be publicly accessible, however they are by specification required to be placed in /resources folder which is by default publicly accesible. If you make sure that you access all resources using the therefor provided components so that they are never accessed by /resources in URL (but instead by /javax.faces.resource), then you can add the following constraint to web.xml to block all public access to the /resources folder:

<security-constraint>
    <display-name>Restrict direct access to the /resources folder.</display-name>
    <web-resource-collection>
        <web-resource-name>The /resources folder.</web-resource-name>
        <url-pattern>/resources/*</url-pattern>
    </web-resource-collection>
    <auth-constraint />
</security-constraint>
