Code Block
new AbstractHeaderContributor() {

            @Override
            public void renderHead(IHeaderResponse response) {
                //your logic goes here
            }
        };

Removed HeaderContributor and friends. HeaderContributor was a convenience that did not add much and actually made things worth by increasing memory footprint in a lot of cases. Instead we can simply override IHeaderContributor#renderHead(IHeaderResponse) and achieve the same functionality in a simpler and consistent fashion.

Wicket 1.4:

Code Block

public class MyPage extends WebPage {
  public MyPage() {
    add(HeaderContributor.forJavaScript(YuiLib.class, "yahoo-dom-event/yahoo-dom-event.js"));
    add(HeaderContributor.forCss(AbstractCalendar.class, "assets/skins/sam/calendar.css"));
  }
}

Becomes the following in 1.5:

Code Block

public class MyPage extends WebPage {
  public MyPage() {
  }
  public void renderHead(IHeaderResponse response) {
    response.renderJavascriptReference(new PackageResourceReference(YuiLib.class,
      "yahoo-dom-event/yahoo-dom-event.js"));
    response.renderCSSReference(new PackageResourceReference(AbstractCalendar.class,
      "assets/skins/sam/calendar.css"));
  }
}

Likewise,

Code Block

public class MyPage extends WebPage {
  public MyPage() {
    WebMarkupContainer c=new WebMarkupContainer();
    c.add(HeaderContributor.forJavaScript(YuiLib.class, "yahoo-dom-event/yahoo-dom-event.js"));
    add(c);
  }
}

becomes

Code Block

public class MyPage extends WebPage {
  public MyPage() {
    WebMarkupContainer c=new WebMarkupContainer();
    c.add(new AbstractBehavior() {
      public void renderHead(IHeaderResponse response) {
        response.renderJavascriptReference(new PackageResourceReference(YuiLib.class,
          "yahoo-dom-event/yahoo-dom-event.js"));
      }
    });
    add(c);
  }
}
