java.lang.Object org.springframework.web.struts.DelegatingActionUtils
public abstract class DelegatingActionUtils
Common methods for letting Struts Actions work with a Spring WebApplicationContext.
As everything in Struts is based on concrete inheritance, we have to provide an Action subclass (DelegatingActionProxy) and two RequestProcessor subclasses (DelegatingRequestProcessor and DelegatingTilesRequestProcessor). The only way to share common functionality is a utility class like this one.
