JSF Unable to create managed bean X using Eclipse

I'm using Eclipse Indigo. I'm following a patter from this site where it separates the beans in 5 classes, I'm using ModelBean, BackingBean and ControllerBean.

My project structure is:

Java resources -> src -> com.erp3.gui.user with those beans mentioned above

Here is my UserController

package com.erp3.gui.user;

import java.io.Serializable;

import com.erp3.bo.user.UserBO;

public class UserController implements Serializable {

    private static final long serialVersionUID = 1L;
    private UserBO bo;
    private UserModel model;

    public UserController() {
        bo = new UserBO();
        model = new UserModel();
    }

    public void Login() {
        model.setVo(bo.executeLogin(model.getVo()));
        System.out.println("Foi");
    }

    public UserBO getBo() {
        return bo;
    }

    public void setBo(UserBO bo) {
        this.bo = bo;
    }

    public UserModel getModel() {
        return model;
    }

    public void setModel(UserModel model) {
        this.model = model;
    }   
}

When I run the index.html:

<h:inputText label="Usuário" id="username" value="#{userController.model.vo.login}"/>

And I have this exception:

javax.servlet.ServletException: Unable to create managed bean userController.  The following problems were found:
     - Bean or property class com.erp3.gui.user.UserController for managed bean userController cannot be found.
     - Bean or property class com.erp3.gui.user.UserController for managed bean userController cannot be found.
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:321)

I was told that Eclipse doesn't work with annotation, so I have my faces-config

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xi="http://www.w3.org/2001/XInclude"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
 <managed-bean>
  <managed-bean-name>userController</managed-bean-name>
  <managed-bean-class>com.erp3.gui.user.UserController</managed-bean-class>
  <managed-bean-scope>request</managed-bean-scope>
 </managed-bean>
 <managed-bean>
  <managed-bean-name>userBacking</managed-bean-name>
  <managed-bean-class>com.erp3.gui.user.UserBacking</managed-bean-class>
  <managed-bean-scope>request</managed-bean-scope>
 </managed-bean>
 <managed-bean>
  <managed-bean-name>userModel</managed-bean-name>
  <managed-bean-class>com.erp3.gui.user.UserModel</managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
 </managed-bean>
 <application>
  <message-bundle>com.erp3.gui.helpers.messages</message-bundle>
 </application>
</faces-config>

If necessary, I can add my other beans, didn't do because would make a enormous question

EDIT

I have added the annotations on my beans and the problem changed to:

javax.el.PropertyNotFoundException: /views/user/login.xhtml @18,135 value="#{userController.model.vo.login}": Target Unreachable, identifier 'userController' resolved to null
    com.sun.faces.facelets.el.TagValueExpression.getType(TagValueExpression.java:97)
    com.sun.faces.renderkit.html_basic.HtmlBasicInputRenderer.getConvertedValue(HtmlBasicInputRenderer.java:91)
    javax.faces.component.UIInput.getConvertedValue(UIInput.java:1023)
    javax.faces.component.UIInput.validate(UIInput.java:953)
    javax.faces.component.UIInput.executeValidate(UIInput.java:1204)
    javax.faces.component.UIInput.processValidators(UIInput.java:693)
    javax.faces.component.UIForm.processValidators(UIForm.java:240)
    javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1081)
    javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1081)
    javax.faces.component.UIViewRoot.processValidators(UIViewRoot.java:1159)
    com.sun.faces.lifecycle.ProcessValidationsPhase.execute(ProcessValidationsPhase.java:72)
    com.sun.faces.lifecycle.Phase.doPhase(Phase.java:97)
    com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:114)
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:308)

But when I add the beans to the faces-config the error comes back.

Unfortunately it was a tremendous lack of attention.

On my project Build Path I was referencing to jars on my server and another programmer changed those jars addresses so I had broken references.

The weird is that Eclipse haven't send any alert about this issue.

Problem solved.

Thanks BalusC and Montolide for your time and attention.

Eclipse works fine with annotations (or maybe its JBoss tools?), so you should use @ManagedBean on your class.

Are your faces-config on WEB-INF folder?
