That may mean one of a few problems I think. The whole bean is not
found, or just the property. If the configuration file for faces is
"faces-config.xml" and located in the WEB-INF directory, myfaces will
"auto-magically" find it. If it has a different name however, it must
be specifically specified in the web.xml.
Looking at the number guess demo, the name is the "correct" name, and
it is located in the WEB-INF directory, so that should not be the
issue. Also, the manaed-bean for NumberBean is registered in there.
So check:
1. that the class is indeed on the class path (in a jar in WEB-INF/lib
or classes in WEB-INF/classes)
2. verify the presence of the property. Remembering that "getProperty"
results in "property" in the jsp/xhtml
I'm posting this to the facelets user list as well to see if Jacob has
any ideas ([EMAIL PROTECTED]).
