Question

I was trying to create a Controller inheritance to check how does Interceptions work.

The default controller i.e. Application.java is like this:

@Before
static void display(){
    System.out.println("Interception method \"Before\" invoked!!!");
}

public static void index() {
    System.out.println("Inside index!!!");
    render();
}

I created a new controller named App.java and it is like this:

@With(Application.class)

public class App extends Controller {

public static void welcome(String txtName){
    render(txtName);
}

}

Here is the index.html file:

#{extends 'main.html' /}
#{set title:'Home' /}

<form action="@{App.welcome()}" method="get">
Enter your name: <input type="text" name="txtName">
<input type="submit" value="Submit">
</form>

This is Welcome.html file:

#{extends 'main.html' /}
#{set title:'Home' /}

Welcome ${txtName?:'Guest'}

I added this entry in routes file:

GET     /InterceptionDemo                       controllers.App.welcome

When I enter the name and click the button in index.html then I am getting an error:

The template App/welcome.html does not exist.

I am trying to use the App.java controller but it is not working. The welcome.html file is present under the views/Application folder where the index.html is also present.

Please let me know how to make it work…this is just a junk app trying it out for getting started with Play framework inheritance.

Thanks.

Tried your example, and it worked just fine. Placed the Welcome.html file in the wrong directory, and got the same error as you. But then created the views/App directory and placed it there, and it worked.
