所有已实现的接口：

com.opensymphony.xwork2.Result, Serializable, StrutsStatics

public class ServletDispatcherResult
extends StrutsResultSupport

Includes or forwards to a view (usually a jsp). Behind the scenes Struts will use a RequestDispatcher, where the target servlet/JSP receives the same request/response objects as the original servlet/JSP. Therefore, you can pass data between them using request.setAttribute() - the Struts action is available.

There are three possible ways the result can be executed:

• If we are in the scope of a JSP (a PageContext is available), PageContext's include method is called.
• If there is no PageContext and we're not in any sort of include (there is no "javax.servlet.include.servlet_path" in the request attributes), then a call to forward is made.
• Otherwise, include is called.

This result type takes the following parameters:

• location (default) - the location to go to after execution (ex. jsp).
• parse - true by default. If set to false, the location param will not be parsed for Ognl expressions.

Example:

 <result name="success" type="dispatcher">
   <param name="location">foo.jsp</param>
 </result>
 

This result follows the same rules from StrutsResultSupport.
