| A Resource is something that implements IResourceListener and provides a
getResourceStream() method which returns the raw IResourceStream to be
rendered back to the client browser.
Resources themselves do not currently have URLs. Instead, they are referred
to by components that have URLs.
Resources can be shared throughout an application by adding them to
Application with addResource(Class scope, String name) or addResource(String
name). A resource added in such a way is a named resource and is accessible
throughout the application via Application.getResource(Class scope, String
name) or Application.getResource(String name). The ResourceReference class
enables easy access to such resources in a way that is light on clusters.
While resources can be shared between components, it is important to
emphasize that components cannot be shared among containers. For
example, you can create a button image resource with new
DefaultButtonImageResource(...) and store that in the Application with
addResource(). You can then assign that logical resource via
ResourceReference to several ImageButton components. While the button image
resource can be shared between components like this, the ImageButton
components in this example are like all other components in Wicket and cannot
be shared.
