Purpose and usage of “application.path” variable

Question

In the Play! framework source for the main method in Server.java I found these two lines:

File root = new File(System.getProperty("application.path"));
if (System.getProperty("precompiled", "false").equals("true")) {
    Play.usePrecompiled = true;
}

Where can I find the application.path value?

Answer 1

System.getProperty("application.path") that looks like a -D property. So at the start of the server there is a call like java -Dapplication.path=/opt/play/myApp

/play/framework/pym/play/application.py in line 251 makes the work.

Answer 2

There might be a properties file in your application and also there might be a mechanism to load all those properties into System properties.

Search for application.path in your application folder file contents and you may get a clue.

Answer 3

It may be in your application.conf file. Check there.
