Hi…All,

I deployed a very simple web application (which worked successfully in Tomcat
without any configuration changes) to JBoss App server 4.0 & here is the
error it gives. How should I fix this.

Regards,

The trick will be figuring out what is different between Tomcat and JBoss. For example, if JBoss ships it’s own JSF libraries, that might be what is causing the problem ( a conflict with your own libraries).

Got it working finally…

Here are the steps :

1. Delete jbossweb-tomcat55.sar/jsf-lib (Has MyFaces JSF implementation)
2. Make the following changes in web.xml :
<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>*.jsf</url-pattern>
</servlet-mapping>

3. Now deploy & the URL should read :
http://domain:port/<context>/page.jsf
