Getting bean from request scope

Question

Hi,
I am new to JSF and unfortunately I am running into a problem that I am not entirely sure about. I look in other forums and what I am doing looks right but I am not getting the desired result.
In my faces-config.xml file I have a managed bean defined as follows:
<managed-bean>
    <managed-bean-name>LogIn</managed-bean-name>
    <managed-bean-class>lex.cac.tables.RefUsers</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
  </managed-bean>I then have a log on page with a form which contains a user name and password field. The tags are defined as
<h:inputText immediate="false" value="#{LogIn.username}" /> (for username) and
<h:inputSecret immediate="false" required="true"
                               value="#{LogIn.password}" /> (for password)
When I submit the form the web app navigates to a jsp page which attempts to do validation against a database.
The first step though is retrieving the object which is suppose to be in request scope.
I attempt the following but I get back null which causes a NullPointerException. Why can't if find the bean?
ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
Map params         = ec.getRequestParameterMap();
params.get("LogIn");  //null is returned hereWhat am i doing wrong? Can someone please help.
Thanks in advance,
Alex.

Something like that:
FacesContext fc = FacesContext.getCurrentInstance();
RefUsers LogIn = (RefUsers)fc.getApplication().createValueBinding("#{LogIn}").getValue(fc);
String username = LogIn.getUsername();
String password = LogIn.getPassword();
