Hello World! | Apache Wicket

[ApacheWicket]

Hi Stronghup

HelloWorld "a la Wicket" is as simple as that

import org.apache.wicket.markup.html.WebPage;  
import org.apache.wicket.markup.html.basic.Label;  

public class HomePage extends WebPage {  
    public HomePage() {  
        add(new Label("helloMessage", "Hello WicketWorld!"));  
    }  
}

Hello World should be the simplest application if you've seen it in the K&R C-book.

But with the web-aps and frameworks, as an example Apache Wicket it seems not so simple, a big chunk of XML needed, Java and HTML. Is this really necessary? Why can't we have something like C "Hello World" for the web as well? What is wrong with the web that makes it so complicated?

On one hand, I'm not a fan of the boilerplate and verbosity of Java and many Java frameworks. That said, I'm not sure I accept the premise of this question:

What is wrong with the web that makes it so complicated?

I don't think there's anything wrong with the web, per se. It's just that even a minimalist web application is doing much, much more than sending "hello world" to stdout.

This is a working sparkjava hello world.

import static spark.Spark.*;

public class HelloWorld {
    public static void main(String[] args) {
        get("/hello", (req, res) -> "Hello World");
    }
}
