getSharedResources().putClassAlias() no longer exists in 1.5

I was told on the user list to open a ticket for this missing API call. Not sure whether it is a "gap" in 1.5 or there's some alternative (see: http://apache-wicket.1842946.n4.nabble.com/MIIGRATE-1-5-Where-is-quot-getSharedResources-putClassAlias-quot-td3471235.html ).

I used to publish dynamic image resources (retrieved from DB) as follows:

protected void init()

{ super.init(); getSharedResources().putClassAlias(org.apache.wicket.Application.class, "global"); getSharedResources().add("images", new ImageResources()); }

The above would let my image resource reply to the URL:

http://host/resources/global/images?params=...

In 1.5, the SharedResources class no longer has a "putClassAlias()" method, so apparently there's something new.

How do we go about doing this with 1.5?
