How to forward....
Hello: I am trying to develop a small application that contains a Login.jsp, in case of failure the controller must redirect to Login.jsp again; in case of success the controller must redirect to a Java application ,MainMenu.class. I think this is done in struts-config.xml file: http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd";> Is this OK?? What is the right way to do it Any help is welcome. Vangelis _ Windows Live: Make it easier for your friends to see what you’re up to on Facebook. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_2:092009
Re:Re: How to forward request in struts 2.1.6?
by the idea of Convention-plugin(CodeBehind-plugin)--"Zero Config",it provides:
Action location by package naming conventions
Result (JSP, FreeMarker, etc) location by naming conventions
Class name to URL naming convention
Package name to namespace convention
SEO compliant URLs (i.e. my-action rather than MyAction)
the normal mappings don't work in the REST-plugin environment.

so many thanks.
forgive my poor english.
there are some words in this document:
http://struts.apache.org/2.1.6/docs/rest-plugin.html
Also, notice we aren't returning the usual "success" result code in either
method. This allows us to use the special features of the Codebehind Plugin to
intuitively select the result template to process when this resource is
accessed with the .xhtml extension. In this case, we can provide a customized
XHTML view of the resource by creating /orders-show.jsp and /orders-update.jsp
for the respective methods.

Why do you need to do it manually with the request dispatcher? Can't
you use any of the available result types?

How to forward request in struts 2.1.6?
from:
ServletActionContext.getServletContext().getRequestDispatcher("/post/message/"+id).forward(ServletActionContext.getRequest(),ServletActionContext.getResponse());
I want to forward request to http://localhost:8080/post/message/3166,
but it always throws out exception says requested resource not exist.
when replace the string with "/index.jsp",it can work correctly.
so, anyone who can help? I just want to forward request to an ACTION other than
jsp file.
thanks.
Re: [S2] How to forward to another struts mapping
You can do it in two ways - 1. Action chaining using result type="chain" - But as a rule, action chaining is not recommended. 2. Using Redirect-after-post pattern. You'll need to define result type="redirectAction". For example, if you need to redirect from ActionA to ActionB, your struts2 config will look like - ActionB While redirecting, you'll need to persist any data that is needed for subsequest request temporarily on the server side (flash scope in popular lingo :^) ) . You might want take a look at the Scope plugin which provides such support out of the box. - Omkar alexworden wrote: > > Hi, > > I'm trying to process a request to URL-A with Action-A, then display a > home page of URL-B in Struts 2.

Hi, I'm trying to process a request to URL-A with Action-A, then display a home page of URL-B in Struts 2. However, in order to display the view of URL-B, I need to invoke Action-B first. I also want any ActionErrors from Action-A to be present in the view of URL-B. How do I do this? It used to be simple in Struts-1, but I can't figure it out for Struts2.

Re: Login implementation, how to forward user to original destination?
First of all thanks a lot for the fast reply. The problem with storing something in the session is it that if the user tried to access two different pages at once in separate windows and had to login in both, he will be forwarded in both to the last page he tried to access. I think this is a quite realistic scenario, for example if a user was logged in and used the service in separate windows, but was kicked out by the system because he was inactive for a while. Any way to do that? Best, Anton Paul Benedict wrote: > Anton, > > Acegi Security does something similar.

Re: Login implementation, how to forward user to original destination?
Anton, Acegi Security does something similar. The original requests (yes -- the actual request object) is stored in the session when the user's credentials are challenged. If they then succeed at the login page, the original request is taken from the session and forwarded along.

Login implementation, how to forward user to original destination?
I spent quite a few hours today trying to forward the user to his original destination when he has to login in between. I have an interceptor (Authentication) that is called before an action and it forwards to Login.action if the user is not logged in. The problem is that if Login.action returns SUCCESS the struts.xml maps it to a static page (index.jsp) and not the page originally requested by the user. My current solution is it that the Authentication interceptor saves the requested URL as a session attribute and Login.action reads it and makes a getResponse().sendForward(requestedURL). However, I am not happy with this solution and I guess there are some much better solutions out there. Would be great if you could suggest me a better way to do that.

Re: How to forward to a page out of .war file
If you configure your web applications so that the context is shared then you will be able to get resources from the other web applications. See for more details the documentation for the web application context configuration (context.xml). As Struts uses standard RequestDispatcher, then you should get what you need.

Hi,
You can use the below given statements in javascripts to forward the control to
the action.
document.forms[0].action='myAction.do';
document.forms[0].submit();
Thanks & Regards

Re: How to forward to an unknown view in Struts 2?
Sorry for taking so long to get back to everyone on this. This is a side
project of mine and things have been hectic with the day job keeping me from
this.
After doing some experimentation, I've found that your solution below does
work Musachy. It just won't access a property in the request attributes as
I was trying to do. At least it wouldn't do it the way I was doing it. =)
Setting a property in my Struts action class is working perfectly now.
Thanks to everyone that responded.

Re: How to forward to an unknown view in Struts 2?
Thanks again for your help. So perhaps I'm not understanding how to get
this to work. In my action I have this mapping:
@Result(name=Action.SUCCESS, value="/resources/${resource}.ftl", type=
FreemarkerResult.class)
And in my execute method I have:
request.setAttribute("resource", "myPage");
The action is trying to forward to "/resources/.ftl". Which tells me it is
not resolving ${resource}.
Am I missing something?
Thanks,

I want to write a Struts 2 action that will forward the user to a .jsp
dynamically. The flow works like so:
1. A request is made for 'resourceLocator.action?resource=common'.
2. The resourceLocator.action class takes the 'resource' request parameter
and forwards the user to 'common.jsp'.
I'm not able to figure out how this is done in Struts 2, since all actions
only return a String result which must be mapped. I'm trying to avoid
having to map all my resources in this action.

How to Forward Request Parmeters in Struts
Hi, In struts, I have an action Act1 that forwards to a display page Page1. On that page there is a submit button whose action act2 forwards to display page Page2. I need to modify Page1 in such a way that I add an additional submit button whose action Act1A forwards to display page Page1A. On page Page1A there is a button whose action is the same as in the previous flow, Act2, but the request parameters from Page1 and Page1a I'd like to forward to Act 2. What is the best way to handle this? My action, Act1a returns null, but when I'm losing the request parameters from page 1. How do I forward the request parameters from page 1 while maintaining the request parameters from page1a to action2? I hope that this makes sense. Thanks for your assistance. - Get your email and more, right on the new Yahoo.com

In my opinion, Eric, this is a bad solution. There are lots of reasons this

/retrieve.do?id=42.
I agree with Jack here. The code to get back your Collection of objects
based on "id 42" should be about one line. Then maybe another to
populate the request so you aren't really saving maybe lines of code
forwarding to another action. So for example if whatever action is
processing your /retrieve.do?id=42 simply do something like...
retrieveAction(..) -->
String forwardName = "success";
Item item = service.getItemFromDB( 42 );
if ( item == null ) {
Collection items = service.performSearch( 42 );
request.setAttribute("items", items );
forwardName = "itemNotFound";
}else {
//probably put item in scope
request.setAttribute("item", item );
}
return (mapping.findForward(forwardName ));

How to forward from one action to another, with modified parameters?
If a request for
/retrieve.do?id=42
fails (e.g. couldn't find item in database), I'd like to say
request.setStatus(HttpServletResponse.SC_NOT_FOUND);
request.setAttribute("warning", "Not your lucky day.");
and forward (not redirect) the request to
/search.do?query=42
Can this behavior be accomplishing with Struts? Currently I'm using
request.getRequestDispatcher(...).forward(...) with a modified
HttpServletRequest, but there must be a better way (TM)...

Re: How to Forward out of struts to a URL from an Action
In struts you can redirect(not forward) to other page or site.
In your action instead of mapping.findforward use following code
ActionForward toAction= new ActionForward ();
ActionForward fromAction = mapping.findForward("targetURL");
toAction.setPath(fromAction.getPath());
toAction.setRedirect(true);
return toAction;
Please note targetURL is defined in your struts config file.
The above code acts as redirect and not as forward.
Also you can add queryStrings to URL (if required).
Please write me if you need any addtional info.

How to Forward out of struts to a URL from an Action
I would like to forward the user out of struts to a URL after an action executes without additional user input, what is the best way in Struts? I can use a page that has a redirect javascript in it, but is there a facility in Struts to do this? Michael Oliver CTO Alarius Systems LLC 3325 N.

How to forward to an Action in one web app, from the Action of a different web app
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:

I have also used this in the past, but without execution errors (I'm
using Struts 1.1 stable). But as you've rightly spotted, you are
limited to only being able to forward to another method in the same Action.
I, too, felt this was an 'ugly' solution because the Struts Controller
is bypassed and you cannot change your mind about unchaining those
actions without editing Java. I read somewhere authoritative that
ActionForward was created for just this purpose; you chain the actions
in the Struts config file instead.
However, chaining actions programmatically could be a perfectly valid
thing to do though...I've only been using Struts for three months ;-)

I do exactly this in my own apps. I use Struts forward Actions in my
struts-config. What about something like this? (I'm assuming your
exsiting Struts forwards and 'showList' method work):
Struts-Config.xml:
=
Your Action class:
=
public ActionForward execute(/* the usual args */) {
ActionForward forward = new ActionForward("defaultErrHandler");
String method= request.getParameter("method");
if (method!= null && !method.equals("")) {
if (method.equalsIgnoreCase("showList")) {
forward = showList(mapping, form, request, response);
}
else {
forward = super.execute(mapping, form, request, response);
}
}
return forward;
}
...
public ActionForward moveDown(/* the usual args */) {
...
// Success! Now refresh the re-ordered list:
return mapping.FindForward("successShowList");
}
public ActionForward showList(/* the usual args */) {
// hit the DB for the new list and forward to the JSP
// etc.
}
To summarise:
(1) The 'moveDown' handler is called.
(2) It looks up "successShowList" thereby forwarding to
"/forward/product/showList".
(4) "/forward/product/showList" forwards back into your Struts Action
class with a 'method' parameter called 'showList' causing your existing
'showList' method to execute.
That's all off the top of my head Riyad. But I use that approach all
the time.

And it didn't work either, it threw the same exception, EVEN THOUGH
the forward that returns from "showList" is actually pointing to a JSP

Struts 1.1, and I thought I saw somewhere in a longer thread from
March I think that this didn't work in 1.1 but works in 1.2 (nightly

So far everything works fine, however I am running into a problem
when I have my LDA returning a forward BACK to itself. This situation
arises when someone changes the order of a product (maybe they move
it down), so what happens is the "Down" button is pressed, execution
goes to the "moveDown" method in the LDA. At the end of that method,
a forward is returned that actually points to the same LDA, but is
suppose to call the "showList" method (different path). This is done
because after the order of the products is changed, you need to
refresh the page with the list of products again so the user sees the
changed ordering.
However, as you can imagine, I get the following exception after
returning the forward:

parameter (get an IllegalStateException because 'Config is Frozen')
and tried to add a request attribute all by the name I have defined
for the parameter (it happens to be 'method') and none of it worked.
So to recap if this isn't clear so far, going into my LDA to change
the ordering is fine because its from a JSP link where a value for
'parameter' is defined, so the LDA knows which method to call.
However by the end of the "moveDown" method, where I need to send
execution over to the "showList" method, I have no way to define a
parameter value, so when the forward is returned, and execution comes
BACK to the LDA, it has no parameter value (hence the exception).
I've looked into using the "unspecified" method, but it SEEMS to me
like that has the exact same problem... if no parameter is specified,
I STILL want to forward to the showList method in the LDA, but I
still won't be able to set the parameter, and it seems ugly to do a:
protected ActionForward unspecified(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
return showList();
}
Does anyone know how I would be able to forward from one method in an
LDA to another method in the same LDA (or any other LDA for that
matter...)? My entire site is a 1:1 mapping for actions and JSPs, so
users never actually see ".jsp" in their address bar, its always
".do", so being able to go between LDAs is pretty important to me ;)
