Java在WAR内加载ResourceBundle，其中包含几个带有其ResourceBundle的jar

Question

I have a java project called API, it has its own ResourceBundle, because it know the language of the user, and the response is written according to its language. The tests are working fine, I see the messages correctly written.

When I want to use the jar of the API project inside another project, lets call it REST_API, it doesn't find any key from API.

The REST_API has it's own language keys, so the final bundle files should have a merge of the bundles. Right?

I'm using maven to build the jar, wars, etc. Is there any maven plugin that scan the projects, and merge resource bundle files in order to make it work?

Or should I implement it in a different way?

Thanks!

UPDATE

Resources in API project are in:

   src/main/resources/ApplicationMessages_en.properties 
   src/main/resources/ApplicationMessages_es.properties

The following is an example of how I load the bundles:

   private static final String DEFAULT_LANG = "en";
   private static final Locale DEFAULT_LOCALE = new Locale(DEFAULT_LANG);
   private static final ResourceBundle DEFAULT_TRANSL = ResourceBundle.getBundle("ApplicationMessages", DEFAULT_LOCALE, new UTF8Control());

Resource files are placed in a package inside resource folder:

src/main/resources/my.package.api.lang.ApplicationMessages_en.properties
src/main/resources/my.package.api.lang.ApplicationMessages_es.properties

And in the REST API project:

src/main/resources/my.package.api.rest.lang.ApplicationMessages_en.properties
src/main/resources/my.package.api.rest.lang.ApplicationMessages_es.properties

To load those files:

// lang = "es" || "en"
// bundleName = "my.package.api.lang.ApplicationMessages"
// bundleName = "my.package.api.rest.lang.ApplicationMessages"
final Locale locale = new Locale(lang);
ResourceBundle translator = ResourceBundle.getBundle(bundleName, locale);

thanks!
