DILIGENT Provider

HOW TO PLUG 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:

1) Modify yourservice.wsdl importing DiligentProvider.wsdl.

1a) add the namespace mapping: xmlns:diligent="http://diligentproject.org/namespaces/common/provider/DILIGENTProvider"

    	1b) import DiligentProvider.wsdl from standard globus schema location:

<wsdl:import namespace= "http://diligentproject.org/namespaces/common/provider/DILIGENTProvider" location="../../common/provider/DILIGENTProvider/DiligentProvider.wsdl"/> 1c) 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"> 2) 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"/>

3) Add DiligentProvider functionalities to your service Resource class implementation;

3a)import diligent provider package: import org.diligentproject.common.provider.*;

3b)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"/>

4) 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 the DILIGENT provider new ws-properties will be added automatically to registration file):

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