How to get resource bundle file from a directory in java?

Question

I have a code to internationalize an application. I need to load the bundle file, go back twice from the running location and load it.

My code is,

bundle = ResourceBundle.getBundle("../../resources/basic",new Locale("fr", "CA"));
lblUsername.setText(bundle.getString("username"));
lblPassword.setText(bundle.getString("password"));
btnLogin.setText(bundle.getString("login"));

I got the following error.

java.util.MissingResourceException: Can't find bundle for base name ../../resources/basic, locale fr_CA

Answer 1

As far as I remember the Bundle class will lookup by default on the current ClassLoader to find your resource. If you want to look a file on the filesystem, please use that instead:

File file = new File("the path of the folder containing the bundles");
URL[] urls = new URL[]{file.toURI().toURL()};
ClassLoader loader = new URLClassLoader(urls);
ResourceBundle rb = ResourceBundle.getBundle("the bundle name", your_locale, loader);

Answer 2

ResourceBundle.getBundle("../../resources/basic",new Locale("fr", "CA")); 

change the first argument to fully qualified class name and make sure that basic_fr_CA.properties exists.

for example if your file is at

/resource/basic_fr_CA.properties location, 

then change your java code to

ResourceBundle.getBundle("resources.basic",new Locale("fr", "CA"));
