jsf2 xhtml pages not interpreted by browser [duplicate]

Answer 1

Basically, MyFaces' JSF 2 implementation is returning blank pages whenever there's any error on either a configuration file or whatever. Worse yet, the errors aren't being sent to the log, either. Use Mojarra (Oracle's JSF 2 implementation) instead, and you'll start getting clear error messages.

Answer 2

RichFaces has it's own configs in web.xml (RichFaces Filter etc.), so if you don't want to use it, you should remove the library because you're not applying any suitable configuration for it, in order to trigger it properly.

Answer 3

That can happen when you have sent a request whose URL does not match the URL pattern of the FacesServlet which in turn causes that the JSF works won't run at all. According to the URL pattern of your servlet mapping, you have to request your XHTML page with .jsf extension. Imagine that you've an index.xhtml, then you'd need to invoke it by http://localhost:8080/contextname/index.jsf.

I however recommend to just replace the *.jsf URL pattern by *.xhtml so that you never need to worry about and fiddle with suffixes. Change your web.xml as follows:

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

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

And open the page by http://localhost:8080/contextname/index.xhtml.
