从JFileChooser获取file.properties并在ResourceBundle上使用它

Question

Currently I am building a Java Desktop Application where the user can load a file.properties through JFileChooser to set the language. However, it throws me an exception: Can't find bundle for base name language.properties, locale pt_BR.

My file name is language.properties so I don't know what is wrong. I want to load the default language.properties file and not language_en.properties for example. Here is my code:

JFileChooser fileChooser = new JFileChooser();
int returnValue = fileChooser.showOpenDialog(null);
if (returnValue == JFileChooser.APPROVE_OPTION) {
File selectedFile = fileChooser.getSelectedFile();
URL[] urls = null;
try {
urls= new URL[]
{
selectedFile.toURI().toURL()
};
} catch (MalformedURLException e){// TODO Auto-generated catch block
    e.printStackTrace();
}
    String fileName = selectedFile.getName();
    int pos = fileName.lastIndexOf(".");
    if (pos > 0) {
      fileName = fileName.substring(0, pos);
    }
    ClassLoader loader = new URLClassLoader(urls);
    ResourceBundle bundle = ResourceBundle.getBundle(fileName,Locale.getDefault(),loader);
}

Any help would be greatly appreciated.

I corrected the issue. I was setting the absolute path to the urls array but I should have set only the path.

Here is the right code:

    JFileChooser fileChooser = new JFileChooser();
    int returnValue = fileChooser.showOpenDialog(null);


    if (returnValue == JFileChooser.APPROVE_OPTION) {
        File selectedFile = fileChooser.getSelectedFile();

        int pos2 = selectedFile.getAbsolutePath().lastIndexOf(selectedFile.getName());
        String path = null;
        path = selectedFile.getAbsolutePath().replace(selectedFile.getName(), "");
        File file = new File(path);
        URL[] urls = null;
        try {
            urls=new URL[]{
                    file.toURI().toURL()
                    };} 
        catch (MalformedURLException e){// TODO Auto-generated catch block
                    e.printStackTrace();
                }
        String fileName = selectedFile.getName();
        int pos = fileName.lastIndexOf(".");
        if(pos > 0){
            fileName = fileName.substring(0,pos);
        }
        ClassLoader loader = new URLClassLoader(urls);
        bundle = ResourceBundle.getBundle(fileName, Locale.getDefault(), loader);
        }

I will make further improvements. Thank you.
