Class DelegatingActionUtils

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

Deprecated. as of Spring 3.0

@Deprecated
public abstract class DelegatingActionUtils
extends java.lang.Object

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.

Since:
1.0.2
