Hello,

I’m trying the JSFLoginDemo and I’ve got an exception while running (http://localhost:8080/JSFLoginDemo/userLogin.faces).

Looks like the Faces context is not found.

I’m new to JSF and it cannot understand what’s wrong with my config. I believe I followed the tutorial step by step as requested.

Any idea ?

Fred

Hi Fred,
Can you post the information about your setup, web.xml file, faces-config.xml file, the EXACT error you get and app server.

Hello,

I found a solution to my problem. It’s linked to JBoss 4.0.5 which bundles Apache MyFaces implementation.

Check
http://docs.jboss.org/jbossas/jboss4guide/r4/html/ch9.chapt.html

I made sure to unbundle MyFaces and everyhting works now.
