How to call Scala method in Java class

Question

As I need that Play application should load and read a single message file, I was thinking of calling loadMessages() method of MessagesPlugin class of Scala from my Application class of Java and pass the path of single message file. I am assuming that when my application will boot , it will call loadMessages() method of Scala and create map of single message file. Kindly rectify if my understanding is wrong.

As I am totally new to Scala programming , kindly rectify me If I am calling Scala method in Java class in wrong way:

import play.api.i18n.MessagesPlugin;
class Application{
      private static boolean renderHomePage(){
        language="en";        
        String configPath=System.getProperty("IUI_CONFIG_DIR");
        MessagesPlugin.loadMessages(configPath+"/"+language+"/messages."+language);
        changeLang(language);       
        setSessionData(true);
        return true;
    }
}

But my above code is unable to recognize loadMessages(). Do I need to import something else.

As you can see here, loadMessages is protected. You have to extend MessagesPlugin to be able to call that method.

In your link , method is shown as protected and in this link loadMessages method is private.So which one I should refer.

Depends on your version. My link is from master (newest version), yours is from version 2.0.

I am using 2.1.3 version of play in my project and in that loadMessages method is private. Can we override private method of scala in java?If yes , any link or example will be highly useful.
