Class DelegatingActionUtils

java.lang.Object
  org.springframework.web.struts.DelegatingActionUtils

public abstract class DelegatingActionUtils

extends java.lang.Object

Common methods for various ways to make Struts delegate to Spring-managed Actions.

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.
