Using Xforms App as a service

Hello All,

I have xforms code which I want to call from two different xforms apps.

I have implemented this as follows:
- common xforms code (lets call it XC) is written as separate app
- other xforms apps (lets call them X1 and X2) are calling XC using post-submission with replace attribute set to none

Alternate way to achieve this would be either including XC in both X1 and X2 using xi:include or
by rewriting XC code in XPL.

I am wondering if there is any alternate and better way to do this .

Thanks,
Harshal

Re: Using Xforms App as a service

After playing a little with XML processors in epilogue.xpl, This is what I came up with:

1. Add entry in page-flow.xml
<config xmlns="http://www.orbeon.com/oxf/controller">
<page path-info="/Services/XForms/test-service" view="/Services/XForms/test-service.xhtml"/>
<epilogue url="oxf:/config/xforms-service-epilogue.xpl"/>
</config>

xforms-service-epilogue.xpl is attachedxforms-service-epilogue.xpl

2. Call test-service.xhtml with xforms:submission

3. In test-service.xhtml write a processing code inside xforms-model-construct-done event.
Inside xforms:body put only single xforms:output statement with id which outputs result of service.

sample test-service.xhtml reads as follows:
<xhtml:html
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xhtml="http://www.w3.org/1999/xhtml">
<xhtml:head>
<xforms:model>
<xforms:instace id="result"><result/><xforms:instance>
<xforms:action ev:event="xforms-model-construct-done">

</xforms:action>
</xforms:model>
</xhtml:head>
<xhtml:body>
<xforms:output id="response" ref="instance('result')"/>
</xhtml:body>
</xhtml:html>

Thanks for sharing this.

Your approach is ok.

For a long time now we have been wanting to add the ability to create
services returning XML fully in XForms. I.e. you could write:

<result>
<xf:model>…</xf:model>
<foo><xf:output value="…"/>
</result>

There is already some code going in that direction, but it's not fully
baked yet.

Another option which works now is to use a submission with
replace="all" and the "echo:" protocol:

<xf:submission id="fr-send-stats" ref="instance('fr-import-stats')"
method="post" action="echo:" replace="all"/>

If you run this upon XForms initialization, instance "fr-import-stats"
will be the response of loading that XForms document. There is no need
to change the epilogue this way.

Re: Re: Using Xforms App as a service

Thanks Erik.

I tried echo: URL scheme as you suggested.
But I get following error-

Expected scheme-specific part at index 5: echo:

Orbeon Version: 3.9.0.201105152046 CE

I also tried echo: scheme on other submissions and that fails with same error as well.

The "echo:" scheme might have been implemented after that. A precursor
was called "test:". Does that one work for you?

Re: Re: Re: Using Xforms App as a service

I tried "test:" scheme as well.
But it works only with replace="none" or replace="instance".

action="test:" and replace="all" fails with same error.
java.net.URISyntaxException: Expected scheme-specific part at index 5: test:

I repeated experiment with milestone build (4.0.0.m9.201208080300 CE) and it worked perfectly
with "echo:" scheme and replace="all"

Thanks for all the help.
