[jboss-user] [JBoss Seam] - Re: Redirecting into view that is inside a directory
If I understand correctly, then I should explain how navigation rules are supposed to
work. This is how your current setup will work: Your /index.jsp will redirect to
/home.seam which, in turn will map to a file in your war called /home.xhtml which will
then be rendered on the front-end. (Note no navigation rule is involved here.)
The navigation rules are supposed to be used as action outcomes: looking at the seam
booking example, there is a login action method that returns an outcome of either
"login" or "main" these outcomes are then mapped, in the
faces-config.xml file (see below), to views.
Seam also introduces the concept of stateful navigation through the use of Pageflows. Have
a look at the seam reference for more info on this.
LoginAction.java extract...
| public String login()
| {
| List<User> results = em.createQuery("select u from User u where
u.username=:username and u.password=:password")
| .setParameter("username", user.getUsername())
| .setParameter("password", user.getPassword())
| .getResultList();
|
| if ( results.size()==0 )
| {
| FacesMessages.instance().add("Invalid login");
| return "login";
| }
| else
| {
| user = results.get(0);
| Contexts.getSessionContext().set("loggedIn", true);
| FacesMessages.instance().add("Welcome, #{user.name}");
| return "main";
| }
|
| }
|
faces-config.xml extract...
| <navigation-rule>
|
| <navigation-case>
| <from-outcome>login</from-outcome>
| <to-view-id>/home.xhtml</to-view-id>
| <redirect />
| </navigation-case>
|
| <navigation-case>
| <from-outcome>register</from-outcome>
| <to-view-id>/register.xhtml</to-view-id>
| <redirect />
| </navigation-case>
|
| <navigation-case>
| <from-outcome>password</from-outcome>
| <to-view-id>/password.xhtml</to-view-id>
| <redirect />
| </navigation-case>
|
| <navigation-case>
| <from-outcome>main</from-outcome>
| <to-view-id>/main.xhtml</to-view-id>
| <redirect />
| </navigation-case>
|
| <navigation-case>
| <from-outcome>hotel</from-outcome>
| <to-view-id>/hotel.xhtml</to-view-id>
| <redirect />
| </navigation-case>
|
| </navigation-rule>
