g051051's answer is still valid in GF4/Payara :

In the admin console (http://localhost:4848), navigate to :

-Configuration
    -server-config
        -JVM Parameters
            -JVM Options

Then, add your parameter prefixed with -D, for instance :

-DBF_DIR_DOC=C:/BU/BF/BFdocuments

In your java code, you can retrieve the property easily :

String directory = System.getProperty("BF_DIR_DOC");

You're done.
