Access JSF ManagedBean from Servlet

Before giving a ready solution I want to clarify some moments that can answer many unasked questions:

• FacesContext is ThreadLocal (but ServletContext is not), that's why you can access it in a static way
• FacesContext cannot be accessed in a static way from a servlet (only if it's FacesServlet)
• FacesContext store it's beans into request attributes, session attributes or application attributes
• You cannot inject @ManagedBean as @ManagedProperty into servlet

Now the answer is simple - JSF beans (if they are already instantiated and managed) can be accessed via attributes

JSF bean:

@ManagedBean(name="SimpleBBean")
@SessionScoped
public class SimpleBBean {
  // managed bean properties
}

and in the servlet:

SimpleBBean simpleBBean = (SimpleBBean) this.getServletContext().getAttribute("SimpleBBean");
SimpleBBean simpleBBean2 = (SimpleBBean) request.getAttribute("SimpleBBean");
SimpleBBean simpleBBean3 = (SimpleBBean) request.getSession().getAttribute("SimpleBBean");
response.getWriter().println("beans: " + simpleBBean + " " + simpleBBean2 + " " + simpleBBean3);

the output will be:

beans: null null SimpleBBean@ebf121

you can also set the scope attributes and then retrieve them from FacesContext
