CURLing orbeon

Hi,

I'm running a PHP app on one server and Orbeon on a seperate Tomcat
server (port 8080). I'm trying to use CURL to request an XFORM from the
Orbeon server and have it work as if it was running directly on the
server. Receiving the XFORM back is fine, and everything looks right in
the page (I set the base url in the HTML header to that of the Orbeon
server).

When I try to use the XForm however I get the message "Unexpected
response received from server" appear as a standard XForm error message.

Are there any other parameters I need to change on Orbeon to get this
route working?

FYI, my PHP code is:

function convert_body($string)
{
$string = str_replace("<html>",'<html><base
href="http://myserver.com:8080">',$string);
return $string;
}

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,
"http://myserver.com:8080/ops/goto-example/xforms-todo");
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec ($ch);

curl_close ($ch);

echo convert_body($result);

Colin,

I doubt changing <base> will do much for anything besides static links
in HTML. The error you are seeing probably means that an Ajax request
failed to contact the server, probably because it was attempted to the
wrong URL. Currently, the JS code naively looks at the URL of the first
script loaded (I think) to determine the URL of the XForms server (the
target of the Ajax requests).

We have a bug entered about doing this better:

http://forge.objectweb.org/tracker/index.php?func=detail&aid=305808&group_id=168&atid=350207

When that is fixed, you should be able to rewrite that more easily. In
the meanwhile, instead or in addition to <base>, you may want to try to
rewrite the script URLs.

Re: CURLing orbeon

Hi Guys,

If anyone's ineterested...

We've finally managed to deploy a sufficient proxy implementation of Orbeon. This allows us to use our PHP server (apache) to serve our app, and keep Orbeon running on it's own separate server to manage our XFORMS (apache tomcat port 8080).

This allows us to mask the Orbeon server from the address bar (and code) but keep the full functionality of Orbeon (ie: real time XFORMS).

To do this we:
created a .htaccess file and put it in our root of our PHP app server. The contents is as follow:
RewriteEngine on
RewriteRule ^call/(.*)$ http://myopsserver.com:8080/ops/goto-example/$1 [P]

And enable mod_proxy and modproxyhttp

Hope this helps someone! :-)
