We are looking for an example of SOAP call for Workflow web service to delegate an activity to a user.
Tried the following :
<soapenv:Envelope xmlns:soapenv="[url]http://schemas.xmlsoap.org/soap/envelope/[/url]" xmlns:api="[url]http://infinity.com/bpm/ws/v2009a/api[/url]" xmlns:query="[url]http://infinity.com/bpm/ws/v2009a/api/query[/url]">
<soapenv:Header/>
<soapenv:Body>
<api:delegateActivity>
<api:activityOid>30</api:activityOid>
<api:participant/>
</api:delegateActivity>
</soapenv:Body>
</soapenv:Envelope>
Got the following exception:
<S:Envelope xmlns:S="[url]http://schemas.xmlsoap.org/soap/envelope/[/url]">
<S:Body>
<S:Fault xmlns:ns4="[url]http://www.w3.org/2003/05/soap-envelope[/url]">
<faultcode>S:Server</faultcode>
<faultstring>[b]null is not a valid argument for ParticipantInfoBaseXto[/b]</faultstring>
<detail>
<bpmFault:bpmFault xmlns:bpmFault="[url]http://infinity.com/bpm/ws/v2009a/api[/url]" xmlns="[url]http://infinity.com/bpm/ws/v2009a/api[/url]" xmlns:ns2="[url]http://infinity.com/bpm/ws/v2009a/api/query[/url]">
<faultCode>[b]PublicException[/b]</faultCode>
</bpmFault:bpmFault>
<ns2:exception class="com.infinity.bpm.rt.api.ws.BpmFault" note="To disable this feature, set com.sun.xml.ws.fault.SOAPFaultBuilder.disableCaptureStackTrace system property to false" xmlns:ns2="[url]http://jax-ws.dev.java.net/[/url]">
<message>null is not a valid argument for ParticipantInfoBaseXto</message>

To delegate activity oid 1 to motu (i.e. userOid 1) the correct SOAP UI message to send is:
<soapenv:Envelope
xmlns:soapenv="[url]http://schemas.xmlsoap.org/soap/envelope/[/url]">
<soapenv:Header/>
<soapenv:Body>
<delegateActivity
xmlns="[url]http://infinity.com/bpm/ws/v2009a/api[/url]"
xmlns:ns2="[url]http://infinity.com/bpm/ws/v2009a/api[/url]">
<activityOid>1</activityOid>
<participant
xsi:type="UserInfo"
xmlns:xsi="[url]http://www.w3.org/2001/XMLSchema-instance[/url]">
<oid>1</oid>
</participant>
</delegateActivity>
</soapenv:Body>
</soapenv:Envelope>
The key here is to specify xsi:type, which can be UserInfo, ParticipantInfo. Your initial request did not contain enough information to delegate:
<participant/> is a placeholder for additional information. Stardust provides a range of participant subclasses that can be inserted here.
search in Eclipse for Web Service API, will get result : Infinity Web Services API.
Alternatively you can refer the online Stardust product documentation
ActivityInstanceXto delegateActivity(long activityOid, ParticipantInfoBaseXto participant)
You can add participant for a User (e.g. motu), or a Role (e.g. Administrator) , or just the default participant. So if you want to delegate to a specific User the next question is, what XML should I use?
Types for ALL Web Service operations are specified in
<Infinity Dynamic Project>/ipp-portal/WEB-INF/wsdl/InfinityBpmService.xsd>
Browse this xsd in Eclipse and you will find ParticipantInfoBase and UserInfo - you should also note if class inheritance mandates additional parameters
I've just described a generic method for locating the correct xml payload for an Stardust WS API call via SOAP.
