Calling Java functions from Haxe

Question

I'm trying to call an external Java function from Haxe. How can I call a Java function that I've written from Haxe?

Java code:

public class ExternalClass{

    public static String myFunction(){ //this will be invoked from Haxe
        return "External Java function";
    }

}

Haxe main class:

class Main 
{
    public static function main() 
    {
        trace(myFunction()); //how can I properly access this Java method?
    }
}

Haxe extern class:

extern class Test
{
    public static function myFunction():String;
}

It's possible to do this using a Haxe "extern" class, but should the extern class be defined in the same folder as the Main class and ExternalClass? haxe.org/doc/java/externs — Anderson Green

class Main 
{
    public static function main() 
    {
        trace(ExternalClass.myFunction()); //how can I properly access this Java method?
    }
}

extern class ExternalClass
{
    public static function myFunction():String;
}

Your external class should have the same name that your native java class.

Then you must call your function as a classic static one, prepending the class name to the function name.
