trait Application extends AnyRef

A Play application.

Application creation is handled by the framework engine.

If you need to create an ad-hoc application, for example in case of unit testing, you can easily achieve this using:

val application = new DefaultApplication(new File("."), this.getClass.getClassloader, None, Play.Mode.Dev)

This will create an application using the current classloader.

  10. def getExistingFile(relativePath: String): Option[File]

    Permalink

    Retrieves a file relative to the application root path.

    Retrieves a file relative to the application root path. This method returns an Option[File], using None if the file was not found.

    Note that it is up to you to manage the files in the application root path in production. By default, there will be nothing available in the application root path.

    For example, to retrieve some deployment specific data file:

    val myDataFile = application.getExistingFile("data/data.xml")
    relativePath

    the relative path of the file to fetch

    returns

    an existing file
