Java EE 404 Error on XHTML but Not HTML

I'm learning Java EE through a simple "Hello World" application, and when I run the program using index.html it works well. However, when I run the same program with index.xhtml, it throws a 404 Error saying "The requested resource is not available."

My folder structure is as follows:

When I run the program using index.html, I use the following URL: http://localhost:8081/index.html, and the page shows up with Hello World. And when I run using index.xhtml, I tried both: http://localhost:8081/example2/index.xhtml and http://localhost:8081/index.xhtml. Both give a 404 Error.

My web.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.xhtml</url-pattern>
    </servlet-mapping>
</web-app>

I've also tried multiple browsers (Chrome and Firefox). Any ideas why I'm getting a 404 on XHTML but not HTML?

Solution

  • The solution was pretty simple. When I checked the Tomcat logs, there was a ClassNotFoundException because Tomcat does not come with the jsf-api and jsf-impl jars. I created a new directory in WEB-INF called lib and put the 2 jars there. Yes, you need both jars. Now the XHTML file is found and the 404 goes away.
