Form Runner supports implementing services using XPL (the XML pipeline language), associated with an application or a specific form.
NOTE: This is an advanced feature which requires programming.
Assuming the following:
- App name:
acme
- Form name:
order
If you place a file called foo.xpl
under
WEB-INF/resources/form/acme/service/
A service called foo
is made available the following URL:
/fr/service/custom/acme/foo
Similarly, if you place a file called bar.xpl
under
WEB-INF/resources/form/acme/order/service/
A service called bar
is made available the following URL:
/fr/service/custom/acme/order/bar
The XPL has the following interface:
-
instance
input: contains the XML data posted to the service URL -
data
output: XML data produced by the service
The following example XPL just echoes the incoming data:
<p:config
xmlns:p="http://www.orbeon.com/oxf/pipeline"
xmlns:oxf="http://www.orbeon.com/oxf/processors">
<p:param type="input" name="instance"/>
<p:param type="output" name="data"/>
<p:processor name="oxf:identity">
<p:input name="data" href="#instance"/>
<p:output name="data" ref="data"/>
</p:processor>
</p:config>
