Java EE (Java Enterprise Edition) General Discussion

Hello,
I'm newbie to JSF, so I hope to explain me almost correctly.
I have to call from a jsf page the main page of another jsf application (SecondApplication) passing some parameters.
I thought to pass them in Session. Is it possible, and how ?
What I've written is totally wrong ?

Thanks in advance for any help.

*[FirstApplication]*

String url="http:/192.168.2.100/SecondApplication";



FacesContext fC=FacesContext.getCurrentInstance();



HttpSession session=(HttpSession)fC.getExternalContext().getSession(true);



session.setAttribute("par1","value1");



fC.getExternalContext().redirect(url);

*[SecondApplication]*

FacesContext fC=FacesContext.getCurrentInstance();



HttpSession session=(HttpSession)fC.getExternalContext().getSession(false);



String Par1=(String)session.getAttribute("par1");



System.out.println(Par1);
