Dispatcher Result
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
{@link PageContext#include(String) 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_pathin the request attributes), then a call to{@link RequestDispatcher#forward(javax.servlet.ServletRequest, javax.servlet.ServletResponse) forward}is made. - Otherwise,
{@link RequestDispatcher#include(javax.servlet.ServletRequest, javax.servlet.ServletResponse) include}is called.
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.
Examples
<result name="success" type="dispatcher">
<param name="location">foo.jsp</param>
