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_path" in 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>
</result>
