Ok, we're on the same page with application.xml, but after spending so much
time on this I was starting to question the basics.
I resolved my JNDI problem, which was do to collision between the myfaces
classes in my WEB-INF/lib directory and the default jboss myfaces classes. I
had removed the ../deploy/jsf/libs directory to fix this a while ago, but it
turns out that I needed to add back in a single commons jar.
The bottomline is that I still have problem accessing the beans, but should be
getting closer.
Per your suggestion, I looked up the classloaders for RequirementsManagerBean:

,addedOrder=1}, [EMAIL PROTECTED] url=file:/C:/Program

I'm not sure how to read this...is this showing me an array of multiple
classloaders? Am I looking for duplicates?
At any rate, the good news is that my bean is registered ok:

Nevermind "MyTableManager"...that is from an earlier test I tried.
Now what I don't get is why I can't access any beans, be they normal
FacesBacking beans or EJB 3.0 entity beans. I've posted my faces-config.xml
file above. When I run something like:
<f:view>
| <h:outputText value="#{rmBean.name}"/>
| </f:view>
I get a "javax.faces.el.EvaluationException: Cannot get value for expression
'#{rmBean.name}'" when the above call is made. Now many users have posted this
type of problem and it's a persistence.xml or JNDI lookup problem, but I've
posted my code in my earlier posting and it complies with the latest JBoss
implementation of EJB 3.0 (i.e., following the migration guide and wiki
postings). The stack trace of the EvaluationException above ends with
"java.lang.NulPointerException"

The method I'm attempting to access is in fact getting called because I am
printing a STDOUT from it. Is it finding a copy of the bean class in my WAR
file (I'll have to triple check that they're not there), and then failing to
access the beans in the ear's jar file?
What is interesting (or not) is this exception that happens a bit earlier in
the server log:

Notice the bolded section...that is a result of attempting to peform a JNDI
lookup.
FacesContext fc = FacesContext.getCurrentInstance();
| rm =
(RequirementsManagerBean)fc.getApplication().createValueBinding("#{rmBean}").getValue(fc);
|
I've also tried:
InitialContext ic = new InitialContext();
| rm =
(RequirementsManagerBean)ic.lookup("alpha/RequirementsManagerBean/local");
|
The above, however, I wouldn't expect to be valid since this is a jsf page and
I'm trying to access RequirmentsManagerBean as a managed bean.
I really think this is a problem between JSF managed beans and the JNDI access,
but I don't know where to go from here. The following forum postings have
similar problems, but the most relevent ones don't have any responses.
Googling for info on other sites has really created more questions than
answers. Is the war/jar file separation within my ear the culprit? Are there
better questions I should be asking?
