HOW TO PLUG the DILIGENT Provider into DILIGENT Services.

The DILIGENTProvider provide new ws-resource properties and operation ( not in this first version ) to DILIGENT services.

It's present inside the DHN_installer archive, and automatically deployed on the DHN.

These are the steps to follow:

  • Modify yourservice.wsdl importing DiligentProvider.wsdl.
    • add the namespace mapping:
xmlns:diligent="http://diligentproject.org/namespaces/common/provider/DILIGENTProvider"
    • import DiligentProvider.wsdl from standard globus schema location:
<wsdl:import namespace=
   		 "http://diligentproject.org/namespaces/common/provider/DILIGENTProvider"
   		 location="../../common/provider/DILIGENTProvider/DiligentProvider.wsdl"/>
    • extends DiligentProvider provider in your porttype:
<portType name="YourServicePortType" 
    				wsdlpp:extends="wsrpw:GetResourceProperty
                   	wsrpw:GetMultipleResourceProperties
                   	wsrpw:SetResourceProperties
                    	wsrpw:QueryResourceProperties
	            	wsrlw:ImmediateResourceTermination
		    		wsntw:NotificationProducer
		    		diligent:DiligentProvider">
  • Add DiligentProvider to the list of the provider of your service wsdd file:
<parameter name="providers" value="org.diligentproject.common.provider.DILIGENTProvider GetRPProvider GetMRPProvider

 SetRPProvider QueryRPProvider"/>
  • Add DiligentProvider functionalities to your service Resource class implementation;
    • import diligent provider package: import org.diligentproject.common.provider.*;
    • create an object of class DILIGENTPropertySet instead of SimpleResourcePropertySet:
this.propSet =  new DILIGENTPropertySet(DILIGENTResourceQNames.RESOURCE_PROPERTIES);

this will add 7 new resource properties to your resource:

<xsd:element name="RunningInstanceID" type="xsd:string"/>

			<xsd:element name="ServiceID" type="xsd:string"/>
	
			<xsd:element name="DHNID" type="xsd:string"/>
		
			<xsd:element name="ServiceName" type="xsd:string"/>
	
			<xsd:element name="ServiceClass" type="xsd:string"/>
	
			<xsd:element name="VOName" type="xsd:string"/>
	
			<xsd:element name="ResourceType" type="xsd:string"/>
  • Also you have to modify the registration file that you pass to DIS-IP in order to register also the new ws-properties( in future version of the DILIGENT provider new ws-properties will be added automatically to registration file):
<ServiceGroupRegistrationParameters
   xmlns:sgc="http://mds.globus.org/servicegroup/client"

   xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/03/addressing"
   xmlns:agg="http://mds.globus.org/aggregator/types"
   xmlns="http://mds.globus.org/servicegroup/client">

        seconds -->

   <!-- <Content> specifies registration specific information -->
   <Content xsi:type="agg:AggregatorContent"
      xmlns:agg="http://mds.globus.org/aggregator/types">

      <agg:AggregatorConfig>
      <agg:GetMultipleResourcePropertiesPollType 	

xmlns:registry="http://diligentproject.org/namespaces/informationservice/disregistry/DISRegistryService"

	<!-- ADD the DILIGENT provider Ns -->

      xmlns:provider="http://diligentproject.org/namespaces/common/provider/DILIGENTProvider">

  	   <agg:PollIntervalMillis>60000</agg:PollIntervalMillis>

   	   <agg:ResourcePropertyNames>registry:UniqueID</agg:ResourcePropertyNames>
   	   <agg:ResourcePropertyNames>registry:ResourceType</agg:ResourcePropertyNames>
   	   <agg:ResourcePropertyNames>registry:AuthPolicies</agg:ResourcePropertyNames>
  	   <agg:ResourcePropertyNames>registry:Profile</agg:ResourcePropertyNames>
  	
	<!-- ADD these list of WS-Properties -->
         <agg:ResourcePropertyNames>provider:RunningInstanceID</agg:ResourcePropertyNames>
	   <agg:ResourcePropertyNames>provider:ServiceID</agg:ResourcePropertyNames>
	   <agg:ResourcePropertyNames>provider:ServiceName</agg:ResourcePropertyNames>
	   <agg:ResourcePropertyNames>provider:ServiceClass</agg:ResourcePropertyNames>
         <agg:ResourcePropertyNames>provider:VOName</agg:ResourcePropertyNames>
         <agg:ResourcePropertyNames>provider:DiligentType</agg:ResourcePropertyNames>
	   <agg:ResourcePropertyNames>provider:DHNID</agg:ResourcePropertyNames>
   

 </agg:GetMultipleResourcePropertiesPollType>
 	 </agg:AggregatorConfig>
      <agg:AggregatorData/>
   </Content>

</ServiceGroupRegistrationParameters>


The DiligentProvider Resource Properties are filled during registration to DIS by DIS-IP/NAL methods.
