I have 3 different Struts (1.1) web applications all running in the same
Tomcat (4.1) server. When the user presses a button on a form of one of
the applications, tied to a Struts Action, I would like that Action to
be able to forward control to an Action within a different web
application, which would build the page and display it to the user. I
would like this new application to
be able to "remember" who called it, and at some point, when the user
presses a button that says "Return to original application", the new
application will forward the user back to the original application
at/near the point where they first left it.
In my Current Action.execute() method, I'm doing:
MyAction.execute() ...
//Get the servlet context of the application I want to switch to.
ServletContext newContext =
session.getServletContext().getContext("/webmaint");
//The new ServletContext seems to be correct.
//I can find JSP resources but I really want to forward to an Action
in the new application!!
RequestDispatcher rd =
newContext.getRequestDispatcher("/MainFrameSet.jsp");
rd.forward(request, response);
return(null);
The following exception is generated when I execute this action code:
