Java EE: how to get the URL of my application?

In Java EE, how can I dynamically retrieve the full URL for my application?

For example, if the URL is "localhost:8080/myapplication/", I would like a method that can simply return this to me, either as a String or something else.

I am running GlassFish as application server.

In JSF I was able to achieve this relatively easily using the following helper function (all you need is a reference to the HttpServletRequest:

public static String getRequestUrl() {
    HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
    StringBuffer requestURL = request.getRequestURL();
    if (request.getQueryString() != null) {
        requestURL.append("?");
        requestURL.append(request.getQueryString());
    }
    return requestURL.toString();
}

Inside any servlet or filter you have access to HttpServletRequest which allows you to see what URL was used by the client to access your application, e.g. try HttpServletRequest.getRequestURL().
