    The url-pattern that you specify in web.xml is always a pattern that is relative to the context path of the webapp. So, /Projekt/* means all the URLs under /Projekt, under the context path of the application.

    Since your app is deployed un /Projekt, it means that this url-pattern matches the URL http://localhost:8080/Projekt/projekt/Hai. It doesn’t match http://localhost:8080/Projekt/Hai, because this URL, when written relatively to the context path, is /Hai, which doesn’t matches the pattern /Projekt/*.

    Good rule of thumb: nothing in the code or deployment descriptor of a webapp should ever depend on the context path chosen to deploy the application. Everything should always be specified relatively to this context path.
