config issue jsf with jboss 6

Question

I have set up a project that I deploy to Jboss 6. It is a war file with a bunch of xhtml files. After several hours of searching and increased frustration, I was hoping that someone with more experience with jsf config would be able to help out...

I keep getting the following error and cannot figure out why since I do not have any jsp pages. Nothing in my web.xml points to jsp (see web.xml further below):

Is my config wrong?

I was packaging a jar with the wrong (old) version of jsf, causing this jspView exception. Once I got rid of the jar, the error cleared.

If you are using Primefaces then you are missing all of the Primefaces configurations in your web.xml, including the FileUploadFilter and the ResourceServlet. Below is an example of what you are missing.

  <servlet>
    <servlet-name>Resource Servlet</servlet-name>
    <servlet-class>org.primefaces.resource.ResourceServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>Resource Servlet</servlet-name>
    <url-pattern>/primefaces_resource/*</url-pattern>
  </servlet-mapping>
  <context-param>
    <param-name>com.sun.faces.allowTextChildren</param-name>
    <param-value>true</param-value>
  </context-param>
  <context-param>
    <param-name>primefaces.THEME</param-name>
    <param-value>none</param-value>
  </context-param>
  <filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>
        org.primefaces.webapp.filter.FileUploadFilter
    </filter-class>
  </filter>
  <filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
  </filter-mapping>

OP is apparently using PF 3.0 which doesn't require the resource servlet. Even then, it would likely have generated a different exception. — BalusC, Jan 10 '12 at 04:24
