EL to check session object how?

[Davie Lin]

Hey everyone

If I have a User object and its store in session map like

  
  User user = Model.getUser( login, pwd);
 
  FacesContext context = FacesContext.getCurrentInstance();
  context.getExternalContext().getSessionMap.put("User", user);

What are the EL syntax I need to access the session object, in struts I use ${sessionScope}

Thanks

<h:outputText value="#{User.someProperty}"/>

However, it's not recommended practice to name objects using an initial capital letter.

You can also reference using an explicit scope notation, but I've never needed to do that so far. Since it's also not advisable to name scoped objects with the same name in different scopes.

I believe I visited the official JSF site about EL syntax from oracle.

looks like JSF can use the same implicit object like sessionScope in JSP. That should be no problem if I am using Facelets instead right?

I will remember the naming convention you mentioned

Thanks Tim

Even in basic JSP, it was usually possible to omit the scope and have it determined implicitly. EL continues that tradition. While it may make the process of resolving objects slightly less efficient, since multiple scopes have to be searched, the payback is the flexibility of not having to change all your references if the scope needs to be changed.
