How to redirect flow between two beans?

shasho Jul 11, 2006 1:22 PM

The general question is how can I direct the flow of the program from one java action bean to another?

Here is a scenario

1. User log in using username and password
2. An action bean checks the username/password (loginAction.java)
3. Now I want to jump from loginAction.java to a new action bean (displayAction.java) and perform a database search there (displayAction.find)

I have hard time performing step 3! If I redirect from loginAction.java to the DisplayAction xhtml associated with displayAction.java using the ?navigation-case? I cant call the ?find? because the EntityManager in displayAction.java is null thus the DisplayAction xhtml appears empty

Following seam booking demo program

Let?s say that after a successful login we want to perform an automated search that shows all the available hotels

In the file LoginAction.java under the login function in case of successful login
?..
user = results.get(0); Contexts.getSessionContext().set("loggedIn", true); FacesMessages.instance().add("Welcome, #{user.name}"); // here I want to redirect to hotel search instead of displaying the main page // need to call HotelSearchingAction.find return "main";

and return "hotelSearch" or whatever instead of "main" isn't what you want?

I want to call specific function in hotelsearch - find and not just load it

I want to know how to direct to a specific fucntion inside hotelsearch which is a Java bean

If all you want to do is call some method you could use a page action.

I have a feeling there's more to your story, but will need more information about what it is you're trying to do. You may also benefit from reading about the @Factory and @Unwrap annotations.

I'm not sure I follow, but if as your comment states you want to call the method from another seam managed bean try:

@In(create = true)
private HotelSearchingAction hotelSearchingAction

user = results.get(0);
Contexts.getSessionContext().set("loggedIn", true);
FacesMessages.instance().add("Welcome, #{user.name}");
// here I want to redirect to hotel search instead of displaying the main page
// need to call HotelSearchingAction.find
return hotelSearchingAction.find();
