Is it possible to obtain an application's base url from the Java Play API? Right now, I'm hard coding the port in application.conf, and assuming the hostname as "localhost" to derive the base url as follows:

String baseurl = "localhost" + Play.current().configuration().getInt("application.port").get().toString();

In my application.conf, I have

application.port=7000

There must be a better way.

Thanks for any help.

You can just get the absolute URL to your Home Page action

routes

# Home page

GET / controllers.Application.index()

Application.java:

String baseUrl = routes.Application.index().absoluteURL(request());

Of course you can also use this trick in the template if required:

<head>

<title>@title</title>

</head>

Thanks for your reply. I'm doing this from a multi-threaded controller, and it's giving me the following error:

Exception in thread "Thread-406" java.lang.RuntimeException: There is no HTTP Context available from here.
    at play.mvc.Http$Context.current(Http.java:27)
    at play.mvc.Controller.request(Controller.java:28)

I found my problem. I got this exception because I was trying to parse HTTP responses without properly getting an HTTP stream to hold those responses. Fixed now.
