Java ResourceBundle

Question

I haven't programmed in Java for months and I have a small application to develop for my own usage. I am stuck on ResourceBundle ! I remember it to be very easy to use, so I guess my problem is something very easy to solve but needs new eyes :)

Locale frLocale = new Locale("fr","CA");
Locale enLocale = new Locale("en","CA");

String dir = System.getProperty("user.dir");
System.out.println("current dir = " + dir); // current dir = D:\RP1.8.2

Path p = FileSystems.getDefault().getPath(dir,"test.properties");
System.out.println("Path : "+p.toAbsolutePath().toString()); // Path : D:\RP1.8.2\test.properties

boolean exists = Files.exists(p);
System.out.println("File found: "+exists); // File found: true

ResourceBundle bundle = ResourceBundle.getBundle(p.toAbsolutePath().toString());
/* Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name D:\RP1.8.2\test.properties, locale fr_CA */

String title = bundle.getString("main.title");
System.out.println("Titre = "+title);

So my properties file exists but the ResourceBundle doesnt find it ... weird. In the user directory i have 3 files: test.properties, test_fr.properties and test_fr_CA.properties

Any clue for me ? Thanks

The argument to getBundle is not a file name, and in fact must not be a file name. ResourceBundle files are application resources, and need to be placed in the same location as your compiled classes. (In fact, a ResourceBundle can be an actual Java class instead of a properties file.) For example:

build
└─classes
  └─com
    └─example
      └─myapp
        ├─MyWindow.class
        ├─MyDataImporter.class
        ├─test.properties
        ├─test_fr.properties
        └─test_fr_CA.properties

Code:

ResourceBundle bundle = ResourceBundle.getBundle("com.example.myapp.test");

如果它是一个Maven项目，那么我将右键单击该项目，然后在“ M2工具”下选择“生成工件（检查更新）”，然后单击“生成OSGI捆绑包”
