[[EMAIL PROTECTED]]

I see, thats pretty good idea, will do like you wrote, I'm quite lazy in 
repeating the code, so that solution is for me :)

Thanks everyone for help :)

You shouldn't need to do direct session/request manipulation as long 
as you have a facescontext.

I also don't like including all this FacesContext/ValueBinding code in 
every managed bean. Too much clutter.

Better is a utility class that performs such lookups between managed 
beans:

public class WebLookup {
    
    /**
     * Look up a managed bean by JSP-EL value-binding expression
     * @param ref a value-binding expression to lookup
     * @return the managed bean referenced by the expression
     */
    public static Object getManagedBean(String ref) {
        // Find or create the web-tier data object
        // ref like "#{loginBean}"
        // would return the LoginBean
        FacesContext context = FacesContext.getCurrentInstance();
        ValueBinding binding = 
context.getApplication().createValueBinding(ref);
        return binding.getValue(context);
    }
    
    public static LoginBean getLoginBean() {
        return (LoginBean )getManagedBean("#{loginBean}");
    }

    ...

}

   Hi,
      I'm wondering what solution for that you got boys:
        - how should I pass the password and the user login through 
beans, as I need both of them to retrieve data form database.

   Is good enough to have loginBean.java and then on each bean which 
needs connect to db do something like:
       FacesContext context = FacesContext.getCurrentInstance();
       ValueBinding vb = 
context.getApplication().createValueBinding("#{loginBean}");

       u = ((UserBean) vb.getValue(context));
       userName = u.getLoginName();
       passwd = u.getPasswd();
     Or better solution will be put user and password to the session 
like:
           FacesContext fc = FacesContext.getCurrentInstance();
           HttpSession session = (HttpSession) 
fc.getExternalContext().getSession(false);
           session.setAttribute("USER", loginName);
     and then retrieve it when necessery:
           HttpSession session = (HttpSession) 
context.getExternalContext().getSession(false);
           session.getAttribute("USER");

  Thanks for any suggestion!
