Serving dynamic content with Wicket 1.5

Question

I have my Wicket 1.4 code to have a link to download a file which is generated programatically:

protected class MyWebResource extends WebResource {
    public IResourceStream getResourceStream() {
        .....
        return new StringResourceStream(myString, "text/plain");
    }
}

ResourceLink<?> downloadLink = 
   new ResourceLink<Object>("downloadLink", new MyWebResource());

Everything was good. Now I've upgrade to Wicket 1.5. Now WebResource doesn't exist any more.

I've searched the web for ages, surely this must be a simple problem which has a simple solution? Alas I can't find it.

The replacement is AbstractResource. Basically you should create ResourceResponse and do what you did in its WriteCallback. See the specializations of AbstractResource in Wicket's code for examples. See http://wicketinaction.com/2011/07/wicket-1-5-mounting-resources/ as well.

Hello martin. I am new to wicket and couldn't getting desired result through that example. Could u please elaborate linking part for me. Is it generating image on wicket page or simply providing a link because what I am getting is a link. – Crypt
