Support for forward/include is also available in Struts 1.0, as follows:
* You can use your subservlet as an Action itself, by
forwarding to it:
<action path="/mypath" forward="/mysubservlet" .../>
NOTE: No "type" attribute would be used here.
* You can use your subservlet as an Action itself, by
including it (you would do this if the subservlet
expects to be the target of a RequestDispatcher.include()):
<action path="/mypath" include="/mysubservlet" .../>
NOTE: No "type" attribute would be used here.
* You can forward from your Action to a presentation JSP page
in the usual way, and that JSP page can use <jsp:include>
to merge in content from the subservlet.
* You can stitch together the output of multiple servlets by
using RequestDispatcher.include() multiple times in your
Action, although the previous method (using <jsp:include>)
would generally be preferred.
See the documentation in struts-config_1_0.dtd for more info about the
first two options.
