In addition to this, you should be aware that your proposed code will fail
if your webapp is being run directly from a WAR file rather than from an
unpacked directory. A portable way to do this sort of thing would be:
URL url = getClassLoader().getClass().getResource
("/com/company/app/PropertiesFile.properties");
InputStream in = url.openStream();
Properties props = new Properties();
props.load(in);
in.close();
