retrieve GET parameter in a request bean

Why not store it in the request map and have your bean access that?

I'm sorry, I don't understand what you mean.

request map == face-config?

The url in the email will be something lik

http://myWebSite.com/MyPage.jsf?idDeal=3517&authKey=341AFE80CFB419750D

I want to have a direct access to this page.

>>request map == face-config?

request.setAttribute("x", y);

>>request.setAttribute("x", y);
How do we get this object?

Email are in a mail, I don't think it works and they aren't sent from the same server(and it's not a J2EE server).

Or

http://java.sun.com/javaee/javaserverfaces/1.1/docs/api/javax/faces/context/ExternalContext.html#getRequestMap()

You don't really help here...

When must I use this?
What do I write in the email?
Is this really done for JSP/JSF?(because I see always "servlet" in the javadoc)
How do I get this ExternalContext?

Why is it so complicated???
It's just amazing, I only want to retrieve a Get variable. In php it's only a $_GET['my_var_name'], in .NET it's only a Request.QueryString("parameter1")

The difference is you're using multi-layered technologies. PHP is shallow in comparision. Exactly what layer of your app are you in? If you have access to the request object, then of course it's equally easy

Theses layer must simplify the development no?

I'm in a Bean with a Request scope, in a getter of one attribut of my bean.

>>Theses layer must simplify the development no?

No, that's not the objective. They actually make it more complex. The objective is to increase reusability and scalability

A bean is not meant to have circular references to the request, hence your problem. You would be better to rethink the design, but a kludge would be to pass the request into the bean

But say me how I can do it differently?

I need to have:
-a link from an email
-can load an object corresponding to the given ID in my RequestBean

So the user clicks on a link in an email?

>>can load an object corresponding to the given ID in my RequestBean

What object?

It's an Entity object, I've a facade(session bean) to load it

    @EJB
    private MatchFacadeRemote matchfac;
 
    public Match getMatchToReview() {
        if(matchToReview == null){
            int idMatch = xxxxxx;//here we get this object
            matchToReview = matchfac.find(idMatch);
        }
        return matchToReview;
    }

Select allOpen in new window

What is the first thing that gets hit when the user clicks on the link in the email? Do you have jsp, servlet or what?

It's a JSP page

Yeah it's an email, it was specified in the first message ;)

In that case it would be e.g.

String authKey = request.getParameter("authKey");

Select allOpen in new window

I've try but I don't have this request var

That's *always* present in a jsp

I'm confuse, I've responded to fast to your question, I've only JSF pages

In that case we're back with http:#24905473

See http://www.java-samples.com/showtutorial.php?tutorialid=474

I've tried to create an ExternalContext, but it's an abstract class.

I've created a FaceContext, but there isn't any getRequestMap on this method.

I've check there isn't any :

get***Map() on the ExternalContext

You need to read the link i posted to you - it tells you exactly what to do

Okay,

So I've try to do mixes, but when I call the page like this:
http://localhost:8080/TrustBN-war/faces/ReviewExchange.jsp?idReview=120938120839

I get a null in my code

FacesContext context = FacesContext.getCurrentInstance();
String idReview = (String)context.getExternalContext().getRequestMap().get("idReview");
System.out.println(idReview);

Select allOpen in new window

Yeah it works

Thank you sooo much!
