How to get the session variable value in JSF

Question

Hi
This is Subbus, I'm new for JSF framewrok, i was set the session scope for my LoginBean in faces-config.xml file..
<managed-bean-name>login</managed-bean-name>
<managed-bean-class>LoginBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope> like that...
So all parameter in LoginBean are set in session right ?... for example i used userId is the Parameter...
Now i need to get the the userId parameter from that session in my another JSP page.. how i get that ?..
Already i tried
session.getAtrribute("userId");
session.getValue("userId");
but it retrieve only "null" value.. could u please help me.. it's very urgent one..

Answer 1

Where i use that..is it in jsp or backend bean...
simply i use the following code in one backend bean and try to get the value from there bean in the front of jsp page...
in LogoutBean inside
public String getUserID()
     Object sessionAttribute = null;
     FacesContext facescontext=FacesContext.getCurrentInstance();
     ExternalContext externalcontext=facescontext.getExternalContext();
     Map sessionMap=externalcontext.getSessionMap();
     if(sessionMap != null)
     sessionAttribute = sessionMap.get("userId");
     System.out.println("Session value is...."+(String)sessionAttribute);
     return (String)sessionAttribute;
     return "fail";
JSP Page
<jsp:useBean id="logs" scope="session" class="logs.LogoutBean" />
System.out.println("SS value is ...."+logs.getUserID());
but again it retrieve only null value.. could u please tell me first how to set the session variable in JSF.. i did faces-config only.. is it correct or not..
