struts result going to a current page
I want to define a global exception handler where if this exception happens,
it goes to the current page
Is there any way to get the current page and specify it as the result ?
Thanks

You won't get an argument from me.

Ew.
It's almost enough to make me want to put the request object in as a named
thingie. That and the current action (as #action, I would have sworn we all
talked about that at one point? to avoid issues with multiple pages,
iterators, etc. and property shadowing).

Thanks. Since this poster isn't asking for the request URL, but the
page from which that request was submitted, which is the Referrer, I
think that means they want:
<result name="redirectToReferrer" type="redirect">
<param
name="location">${#context.get(@org.apache.struts2.StrutsStatics@HTTP_REQUEST).getHeader("Referer")}</param>
</result>

That's correct; #request is the request context, not the request itself.
I posted the OGNL for getting the actual request a few days ago; it's a
little twisted. From that post (which was asking how to get the current
request URL):
<s:property
value="#context.get(@org.apache.struts2.StrutsStatics@HTTP_REQUEST).getRequestURL()"/>

Since I've never used Beehive, and I don't feel like digging through
it's internals to figure out how it determines what the "previousPage"
was, or how it forwards there, I can't tell you exactly what this does.
In general, though, what I'm telling you is that you have two choices.
You can either have your global result of type httpheader and simply
return 204 so the request completes but the person is left on whatever
page they were previously viewing, or you can look in the request to see
what the "referer" page is, and if set, you can send a redirect to it.
<global-results>
<result name="noAnswer" type="httpheader">
<param name="status">204</param>
</result>
<result name="redirectToReferrer" type="redirect">
<param name="location">${#request.getHeader("Referer")}</param>
</result>
</global-results>
<global-exception-mappings>
<exception-mapping exception="recoverableExceptionBaseClass"
result="one-of-the-two-above"/>
</global-exception-mappings>
-Dale
P.S.: If that request.getHeader bit doesn't work, it's because I think
the OGNL #request object might be the request namespace rather than the
actual HttpServletRequest object. I think that's a standard stumbling
block, but it's late and I don't recall the standard solution -- can
someone else please chime in?

To be more specific, Here is we can do in Beehive Pageflow which is based on
struts 1.x
I am trying to do a similar thing in Struts 2
@Jpf.ExceptionHandler(forwards = { @Jpf.Forward(name = "recoverableError",
navigateTo = Jpf.NavigateTo.page) })
protected Forward handleRecoverableException(
RecoverbaleException ex, String actionName,
String message, Object form) throws Exception{
// code
this.addActionError(Globals.ERROR_KEY, key, null);
return new Forward( "recoverbleError" );
}
The above is the global exception handler. If any RecoverbaleException
happens anywhere in the application the request is send back to the current
page by means of Jpf.NavigareTo.Page
Thanks

Yes,
I want to return to whatever page referred the current request. Whenever a
recoverable exception happens, I want to return to the current page so that
user can take some action
I am trying to avoid defining exception handling at each action level and
do globally and want to access the current page
Thanks

That desire is not well specified. Do you mean you want to return to
whatever page referred the current request? Do you really want to
re-load that page (which may or may not be from within your webapp), or
is simply not changing the content currently being displayed sufficient?
The http return code 204 (or "no content") will leave the browser where
it was.
Otherwise it sounds like you want to redirect to the "referer" (yes,
it's misspelled in the specification). Note if that page was the result
of a POST you pretty much can't redirect to it.

I am working on struts2.
I cannot return null from the action.
I want the current page in the global exception handler. Instead of giving a
specific jsp page, I want to return to what ever the current page is
