PrimeFaces Theme does not apply (maven)

Question

I am trying to change the default theme (aristo) of my web application to "cupertino". I followed several tutorials without any success. I used the following instruction from https://www.primefaces.org/documentation/ : Picture of instruction but the theme did not change

I am using
- Spring Framework
- Maven
- Eclipse
- Primefaces 5.3

Here is my whole web.xml

I found out that no matter what i type in my web.xml file as param value I get the same result -> no changes to the theme
<param-value>something</param-value>

The webapp starts and I don't get any errors! Am I blocking something? Or do I forgot something?

There are no dependencies in your pom. Is that correct? I would expect at least both PrimeFaces and the theme there. — Jasper de Vries
Thanks for your reply. I have both dependencies (primefaces and the one for the theme) in my pom file. Both are in the <dependencies> section above. I dont see what I did wrong. — 1anmeldename

It seems that Spring is ignoring the parameters from web.xml I tried a workaround creating a java class which passes the parameter on startup:

import javax.servlet.ServletContext;
import javax.servlet.ServletException;

import org.springframework.boot.web.servlet.ServletContextInitializer;
import org.springframework.context.annotation.Configuration;

@Configuration
public class CustomServletContextInitializer implements ServletContextInitializer {

    @Override
    public void onStartup(ServletContext sc) throws ServletException {
        sc.setInitParameter("primefaces.THEME", "cupertino"); 
    }

}
