I am using the following code sample to try to retrieve IContributor from IContributorHandle in a advisor, which I had noticed on another forum post:

                IContributorHandle owner = workItem.getOwner();
                IRepositoryItemService itemService = getService(IRepositoryItemService.class);               
                IContributor user = (IContributor) itemService.fetchItem(owner, null);

I don't see any compilation errors in the project.

However, when the advisor runs, I get  the following error:
Problem
An unhandled exception occurred during "Check Owner Advisor".

The service 'com.pb.CheckOwnerAdvisor@35f835f8' failed to find the required service 'interface com.ibm.team.repository.service.IRepositoryItemService'.  Check <prerequisites> in plugin.xml.

I would deeply appreciate feedback on the issue.

Thanks.

Check the particpants plugin.xml, there is a <prerequisites> block.
You'll need to be sure you have
                <prerequisites>
                    <requiredService interface="com.ibm.team.repository.service.IRepositoryItemService"/>   
                     .
                     .
               </prerequisites>

Susan, When I add prerequisites, I am getting a warning that prerequisites is not legal as a child of element extensionService.  Is this warning normal?          <extensionService                componentId="rtc-check-owner-advisor.extensionService"                implementationClass="com.pb.CheckOwnerAdvisor">                <prerequisites>  <requiredserviceinterface="com.ibm.team.repository.service.IRepositoryItemService"/>                   </prerequisites>          </extensionService>

if you have the manifest file open in the eclipse editor, you may want to look at the dependencies tab. 

You must have an entry here for com.ibm.team.repository.service. 

If you dont find it, please revisit your Target Platform to add the required library to it and add the dependency in the plugin configuration. 

hope this helps.

I don't see the Prerequisite block in plugin.xml. I could try adding it to see if it makes a difference as was pointed out by previous comment. However, here is the content of the manifest, which does show the Require bundle: Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: Rtc_check_owner_advisor Bundle-SymbolicName: rtc_check_owner_advisor;singleton:=true Bundle-Version: 1.0.0.qualifier Bundle-RequiredExecutionEnvironment: J2SE-1.5 Require-Bundle: com.ibm.team.process.common;bundle-version="1.2.0",  com.ibm.team.repository.common;bundle-version="1.1.0",  com.ibm.team.repository.service;bundle-version="1.1.0",  com.ibm.team.workitem.common;bundle-version="2.3.0" Import-Package: org.eclipse.core.runtime;version="3.4.0"

the manifest content looks ok to me.. i have 403 setup with similar manifest file and the operation advisor thus created works well.... yes, though i dont see the <prerequisite> on my plugin.xml, you may still want to try the suggestion from Susan... let us know how it goes

the prereq block is optional..    here is part of a plugin.xml for one of my plugins
you can get to it from the plugin.xml editor UI as well.. right click on the elements in the Extensions tab for additional items. (see image below)

  <extension
         point="com.ibm.team.process.service.operationParticipants">
      <operationParticipant
            class="com.sd.tools.CreateApprovalParticipant"
            id="com.sd.tools.workitem.createapproval.participant"
            name="Create Approval Participant"
            operationId="com.ibm.team.workitem.operation.workItemSave">
            <extensionService
                componentId="com.sd.tools.workitem.createapproval.participant.component"
                implementationClass="com.sd.tools.CreateApprovalParticipant">
                <prerequisites>
                    <requiredService interface="com.ibm.team.repository.common.service.IContributorService"/>   
                    <requiredService interface="com.ibm.team.workitem.common.IAuditableCommon"/>        
                    <requiredService interface="com.ibm.team.process.service.IProcessServerService"/>
                    <requiredService interface="com.ibm.team.workitem.service.IWorkItemServer"/>
                    <requiredService interface="com.ibm.team.repository.common.service.IQueryService"/>
                    <requiredService interface="com.ibm.team.repository.service.IRepositoryItemService"/> 
                </prerequisites>
            </extensionService>
            <description>
              some description here
            </description>      
      </operationParticipant>
   </extension>

Thanks Susan, Mark.
Adding the prerequisite block helped.
