using webservices in xforms

Hi there,

in a project i had the pleasure to take over, a lot of handcoded xforms were used inside
an intalio environment.
Those xforms are extremely powerful, but to be honest, i only understand half of it (or not even).

Now i want to extend one of these forms, and include webservices to fill in the dummy lists.
E.g. in the appended formevc.xform there is a dummy instance 'users-instance'
and there is a TODO in the xforms-ready event to "load the list of users".

I have implemented a webservice, that returns a list of users, in the same format as before (see appended WSDL file).
Now i need to get it called from the xform itself.

I have been searching the orbeon website and the web, but there are very little tutorials or explanations how to use WSDL webservices from xforms.

Could you give me a few pointers ? I think i found an example that uses a SOAP webservice (without any explanation),
but it starts its action on form-submission. How do i start an action on an event ?

<xforms:instance id="ws-request">
                <SOAP-ENV:Envelope>
                    <SOAP-ENV:Body>
                        <m:GetQuote xmlns:m="<a href="http://ws.invesbot.com/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> http://ws.invesbot.com/">
                            <m:symbol>GOOG</m:symbol>
                        </m:GetQuote>
                    </SOAP-ENV:Body>
                </SOAP-ENV:Envelope>
            </xforms:instance>

            <xforms:instance id="ws-response"><dummy/></xforms:instance>

            <xforms:submission id="stock-submission" method="post"
                    action=" <a href="http://ws.invesbot.com/stockquotes.asmx" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://ws.invesbot.com/stockquotes.asmx"
                    ref="instance('ws-request')" replace="instance" instance="ws-response"
                    mediatype="application/soap+xml; action="<a href="http://ws.invesbot.com/GetQuote12" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://ws.invesbot.com/GetQuote12 ""/>

I can fill in the SOAP-header, using SOAPUI, but then it stops.

Please, any tips ?

Kind regards,

Nathan

Re: using webservices in xforms

Hi Nathan,

When using SOAP style web services, one strategy is to

write a handler in an xpl file that uses the delegation processor.

You can also transform the result , if needed, so that it is a proper

XForms instance.

http://www.orbeon.com/ops/doc/integration-webservices

This way, you likely would not need any SOAP elements in your

XForms view -- all "clean" instances. And your submission elements

would use the replace="instance" attribute.

Hank,

Yes this is possible, although I find it often easier to just paste the
SOAP envelope in XForms. This way, you don't need to write a separate
XPL file, add an entry in the page flow, or deal with the oxf:delegation
processor.

Which way is the easiest may depend on the particular use case.

Nathan,

That's right, we are a little short on the Web Services documentation.
However you can do a lot from XForms. Just last week, I called Alfresco
Web Services from XForms without major issues.

In your example below, you can call the "stock-submission" with a simple
submit button:

<xforms:submit submission="stock-submission">
<xforms:label>Try me</xforms:label>
</xforms:submit>

This should do for testing.
