JSF does not find managed bean
Hi, everyone. I'm learning JSF and I'm having some
headaches.
I have a managed bean called LogonBean with two String
attributes, login and password, their getters and
setters and a method called logon(). In the jsp I have
a commandButton that calls the logon method.
When I click the commandButton, logon() is never
called; instead, an error message "Conversion Error"
is displayed. As my attributes are both String and no
conversion is required, I put immediate="true" on the
button to skip validation/convertion. Then, this
exception was thrown:
-------------------
18:16:01,859 ERROR [[Faces Servlet]] Servlet.service()
for servlet Faces Servlet threw exception
javax.faces.FacesException: Error calling action
method of component with id logonForm:_id3
at
org.apache.myfaces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:74)
at
[...]
Caused by: javax.faces.el.EvaluationException:

at
org.apache.myfaces.el.MethodBindingImpl.invoke(MethodBindingImpl.java:165)

org.apache.myfaces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:63)

at
org.apache.myfaces.el.MethodBindingImpl.invoke(MethodBindingImpl.java:114)
... 26 more
-------------------
I think that the managed bean is not being found, am I
right? Its declaration on faces-config.xml is like
this:
Code:
<managed-bean>
<managed-bean-name>logon</managed-bean-name>
<managed-bean-class>br.com.advocacia.arq.faces.LogonBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
And all my classes are in a file lib.jar which I
declared in application.xml:
Code:
<application>
[...]
<module>
<java>lib.jar</java>
</module>
</application>
Please, does anyone knows what is going wrong?

Re: JSF does not find managed bean
Posted by dr...@yahoo.com.br.
Hi!
I don't think so... I'm pretty sure that the reason of
this conversion error is because the managed bean
(LogonBean) is null... so when it tries to lookup for
its methods, a FacesException is thrown.
I'm saying this because I switched to the Sun RI to
see if it works, but the same conversion error
occurred and the exception said it! The exception was
"could not bound property logon to null bean logon" or
something like this.
Do you know why can this be happening? This is driving
me crazy!

My guess would be that you used "|" (pipe character) instead of "[" =>

<h:inputSecret id="senha"
value="#{logon.senha}"/>
private String password;
I don't see anything beside the above inconsistency, but I'm pretty
sure that you just translated senha to password in your first message
so it'd be more clear.
Try adding this to your form and see if you get better errors.

There's not enough information to speculate why that is happening.
You'll need to post the conversion error stack trace (if there is one).
You should probably also post your full jsp page and full faces-config file.

When I remove immediate=true I receive a "Conversion

Re: JSF does not find managed bean
Posted by Mike Kienenberger <mk...@gmail.com>.
What's probably happening is that you're trying to access your login
and password components from logon. Those values won't contain valid
input if you're skipping the conversion and validation phases.
Remove the immediate=true attribute.
JSF moves data through several stages before it's bound to your
models, and those stages are not reached when you use immediate=true.
First, the data starts as form data in the request.
Then it's set as the "submittedValue" for the component in the
applyValues phase, then it's validated/converted in the
processValidations phase and set as a "localValue" for your component,
then it's put into your backing bean in the updateModel phase.
By using immediate=true, you're executing your action between the
applyValue and processValidations phase, so the only data available is
on the component itself.

Thanks for your answer. Here are my jsp and my managed
bean codes:
Jsp:
------------------
<h:form id="logonForm">
<h:messages/>
[...]
<h:commandButton action="#{logon.logon}"
immediate="true" value="Submit"/>
</h:form>
------------------
LogonBean:
------------------
public class LogonBean {
private String login;
private String password;
public String logon() {
// method impl.
}
// getters/setters
}
----------------
David.

Re: JSF does not find managed bean

What does your jsp look like?
What is the method signature for logon()?
It must be "public String logon()" if you're using
"action="#{logon.logon}" and it must be public void logon(ActionEvent
event) if you're using "actionListener="#{logon.logon}".
