Hi Andrew,
I supposed you was not going to call a webservice (which is server to
server comunication) but send the user to another site, and then
receive back (thru the user browser) the result of the transaction.
This is what i asked in the first few lines of my first answer. If you
have to call a webservice (your server connects to the other server,
the user notices nothing) then the aproach is radically different.

Hi Simone,

You're welcome :)
How so? This is
what comes back to me:
www.mysite.com/continuation-id/value-returned
What happens
next? How do I get the value-returned into the if statement
following the var bizdata line?
This is not simple. If you can manipulate the return url, try to have
the value-returned passed as a parameter (like
www.yoursite.com/continuation-id.continue?value-returned=X ) .
If you can't, then you will have to parse the URL by yourself inside
the flow, and to do this you have to access the underlying JAVA request
object, since the FOM object does not have methods to access the
requestURI.
This is dirty, and YMMV, but it's done this way :
var objectmodel =
Packages.org.apache.cocoon.components.CocoonComponentManager.getCurrentEnvironment().getObjectModel();
var jrequest =
Packages.org.apache.cocoon.environment.ObjectModelHelper.getRequest(objectmodel);
var uri = jrequest.getRequestURI();
var value-returned = uri.substring(uri.lastIndexOf('/') + 1);
I don't know of a way to pass parameters from the sitemap to a
continuation (you can pass them with
OR you can try to rewrite the url, (a match that uses a map:redirect-to
uri="{1}.continue?value-returned={2}") but it's getting dirtier and
dirtier and don't know if it works well at all.
Hope this helps,
Simone

It's not really related to the issue at hand, but instead of issuing a
sendPageAndWait() to a pipeline that just calls another flow function,
you could call that flow function confirmStage() directly and save some
complexity.

IIUC, you're just making an HTTP request to an external URL, passing it
a few parameters, and getting back a one-line text result which you need
to parse? You can do that all within flow by using the HTTPClient
library: http://jakarta.apache.org/commons/httpclient/ (included with
Cocoon).
So instead of your form posting directly to the external site, have it
post to your continuation like normal, then in your flowscript read the
user's inputted values from the form, assemble them into a HTTPClient
request, send that request to the external URL, and parse the response
however you need to.
Is this what you're wanting to do?

Re: Flowscript continuation from external reply
Hi Andrew,
first question. When you say "pass variables to an external site" you
mean "redirect the user to an external site, like a payment gateway,
and then the external site will redirect the user back to me" right?
In that case, the redirectTo function does not suspend the current
execution, and there is no "redirectAndWait" function, so you are
sending the user to the site, but the flow is not waiting for the
response.
You can solve in two ways :
1) Instead of using redirectTo, set up a page with a link to the
external site (like a jx page), then use sendPageAndWait to send this
page to the user, he will click on the link, go to the external site
and all the rest, while your flow will be suspended until the external
site will redirect him to your continuation and the flow will restart.
This is a clean solution, but involves one more step for the user.
2) Create a webContinuation in your flow (you can do this in _javascript_
flow), before the redirectTo. This way you have a "bookmark" in your
flow the user can be redirected to, even if you haven't stopped the
flow directly. This is quite a dirtier solution, but avoids the extra
click. Here is the pseudocode:
continuation = createWebcontinuation();
if (value-returned == null) {
redirectTo(externalSite + continuation.id);
} else {
if (value-returned == true) {
etc etc
}
}
You have to check if there is a returned value because when the user is
redirected back to your site the flow will restart from the line
immediately after the creation of the continuation, so you have no way
to determine if this is the first time the user is entering this flow
or if it's returning from the external site if not checking for the
presence of the return value.
Hope this helps,
Simone

Hi,
I have a

The site will send back a success or failure confirmation based upon
the parameters passed. What I want to do next is continue on the from
the next point in time after the external site was contacted, so:
I want to create
some flowscript which passes variables to an external site, (https://www.externalsite.com/test.asp?contiuation-id=xxx,
var1=x,var2=x) for example, gets a response back from the external site
(http://www.mysite.com/continuation-id/value-returned), and based on the response
sent back does something else following the initial call to the
external site. How do I do this in flowscript?
So what i'm
thinking is something like:
function getResults() {
cocoon.redirectTo("https://www.externalsite.com/test.asp?contiuation-id=xxx,
var1=x,var2=x")
if
(value-returned == 'true') {
do this
}else{
do this
}
}
How do I get back to the point after cocoon.redirectTo() using
the returned continuation-id?
thanks in advance
Andrew
