Play lets us override the default page hander for 404 and 500 errors.

views/errors/404.html 

<!DOCTYPE html>

<html>
    <head>
        <title>Not found</title>
        <meta http-equiv="Content-Type" content="text/html; charset=${_response_encoding}"/>    
    </head>
    <body>
        #{if play.mode.name() == 'DEV'}
            #{404 result /}
        #{/if}
        #{else}
            <h1>Not found</h1>
            <p>
                ${result.message}
            </p>
        #{/else}
    </body>
</html>

views/errors/500.html

<!DOCTYPE html>

<html>
    <head>
        <title>Application error</title>
        <meta http-equiv="Content-Type" content="text/html; charset=${_response_encoding}"/>    
    </head>
    <body>
        #{if play.mode.name() == 'DEV'}
            #{500 exception /}
        #{/if}
        #{else}
            <h1>Oops, an error occured</h1>
            #{if exception instanceof play.exceptions.PlayException}
                <p>
                    This exception has been logged with id <strong>${exception.id}</strong>.
                </p>
            #{/if}
        #{/else}
    </body>
</html>

What is the japid way to do it ?

branaway commented 10 years ago

One way is to change the default 404 page to refer to a japid version, eg: (in app/views/errors/404.html)

<html>
    <head>
        <title>Not found</title>
    </head>
    <body>
        #{if play.mode.name() == 'DEV'}
            #{404 result /}
        #{/if}
        #{else}
        ${cn.bran.play.JapidPlayRenderer.renderWith("japidviews.error404").raw()}
        #{/else}
    </body>
</html>

Then do whatever you want with an Japid based "error404.html" in you japidviews folder.

The above example let your Japid 404 page to handle 404 in prod mode.
