JSF - Web.xml file not found in Web Context

Question

I am having trouble getting my web.xml to recognize a welcome/login file.

The following lines produce something along the lines of "references to 'filename' that does not exist in web content"

<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>

<form-login-config>
    <form-login-page>/login.html</form-login-page>
    <form-error-page>/login.html</form-error-page>
</form-login-config>

Both login.html and index.xhtml exist in ProjectRoot/WebContent

What allows Eclipse, and I assume JSF, to recognize a file in the WebContent folder?

Here is the full web.xml:
