public static void loadFilters() throws MalformedURLException {

        URL[] urls = {filtersFile.toURI().toURL()};
        ClassLoader loader = new URLClassLoader(urls);
        ResourceBundle bundle = ResourceBundle.getBundle(FILTERS_BASE, Locale.getDefault(), loader);

I am trying to load properties file using resource bundle kept outside the code in a separate directory. But when I try to do this way(above code) I am getting error as

ERROR [main] Can't find bundle for base name filters, locale en_US

And If I am keeping this file filters.properties in src/main/resources folder then this code is working fine… but when I keep it outside it doesn’t works.. Don’t know why..

And CONFIG_DIR contains \my\dir\conf and FILTERS_FILE contains filters.properties file.

FILTERS_FILE has value filters.properties and FILTERS_BASE has value filters and urls got the value as [file:/C:/my/dir/conf/filters.properties]

And filters.properties file is in /my/dir/conf/filters.properties

Answer 1

Try having the file point to the directory rather than the actual properties file. So just change the first statement of that method to

File filtersFile = new File(CONFIG_DIR + "/");

If FILTERS_BASE contains filters, that should be enough. You don’t need the full filters.properties name since the .properties prefix is appended by the getBundle method.
