Question

I would like to know how can i read a value of input text from the managed bean.
I know it is possible to read this way and it is very stright forward.

<h:inputText id="username" value="#{mylogin.username}" required="true" />

But what if lets say i have a value like

 <h:inputText id="username" value="some_value" required="true" />

And i want to read this “some_value” in my managed bean.
Is it possible ?

Another question is it possible to access to the session variables in managed bean or should i somehow pass them to there ?

Answer 1

In the latter case that some_value is not bean managed, IMHO. Nonetheless, you can read that. Do something like this,

FacesContext ctx = FacesContext.getCurrentInstance();
HttpServletRequest request =
      (HttpServletRequest)ctx.getExternalContext().getRequest(); 
request.getParameter("username");

Similarly, regarding accessing session variable,

FacesContext ctx = FacesContext.getCurrentInstance();
HttpServletRequest request =
      (HttpServletRequest)ctx.getExternalContext().getSession(false);
