Package org.apache.struts2.dispatcher.ng Description

This package contains a reimagining of the traditional Struts filter dispatchers. Each specific deployment has their own filters to prevent confusion. In addition, the operations have been explicitly pulled into *Operations objects that try to document through method naming what is happening at every step. Here are a few common use cases and how you would manage the Struts deployment:

Simple Dispatcher

 <filter>
     <filter-name>struts2</filter-name>
     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
 </filter>

 <filter-mapping>
     <filter-name>struts2</filter-name>
     <url-pattern>/*</url-pattern>
 </filter-mapping>
 

Deployment with Sitemesh

 <filter>
     <filter-name>struts2-prepare</filter-name>
     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
 </filter>
 <filter>
     <filter-name>sitemesh</filter-name>
     <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
 </filter>
 <filter>
     <filter-name>struts2-execute</filter-name>
     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
 </filter>

 <filter-mapping>
     <filter-name>struts2-prepare</filter-name>
     <url-pattern>/*</url-pattern>
 </filter-mapping>
 <filter-mapping>
