How to retrieve the changesets associated to a workitem via Java API

Luca Martinucci (1.0k294112) | asked Aug 25 '14, 4:35 a.m.
I am developing a Java extension (a follow-up action) to RTC 4.0.5, and I need to retrieve the list of changesets associated to a work item.
I have already managed  to retrieve a IWorkItem object; how can I retrieve its changesets (using server-side classes)?

Hi Luca,

I have never done this but
I'd try to iterate over the links and find links which link to a changeset.

You can retrieve all links from a workItem with:
workItemCommon.resolveWorkItemReferences(workItem, monitor)

Hope this helps

see below an example :

     private List<IChangeSet> getChangeSets(IWorkItem wi)
             throws TeamRepositoryException {
         IRepositoryItemService repositoryItemService = getService(IRepositoryItemService.class);

         ILinkService linkService = getService(ILinkService.class);
         ILinkServiceLibrary linkLibrary = (ILinkServiceLibrary) linkService
         IItemReference workItemRef = IReferenceFactory.INSTANCE
         ILinkQueryPage linkPage = linkLibrary.findLinks(
                 WorkItemLinkTypes.CHANGE_SET, workItemRef);

         List<IChangeSet> changeSets = new ArrayList<IChangeSet>();

         for (ILink link : linkPage.getAllLinksFromHereOn()) {
             // Change set links should be item references
             IChangeSetHandle changeSetHandle = (IChangeSetHandle) link
             IChangeSet changeSet = (IChangeSet) repositoryItemService
                     .fetchItem(changeSetHandle, IRepositoryItemService.COMPLETE);
         return changeSets;

Olivier, thanks for providing me with this example: it worked, with some minor corrections.

In this example there is getService method: 
 IRepositoryItemService repositoryItemService = getService(IRepositoryItemService.class); 
         ILinkService linkService = getService(ILinkService.class);

Where does this come from/what are the contents of this method?

That is server side API. The extension extends AbstractService which provides getService().

See for server and Client API. See to get started.

 Hi Olivier,
In your above answer to fetch change set associated to work item, you have used server API.
Could you please tell me about java client API which does similar thing.
I figured out that instead of IRepositoryItemService we can use IItemManager at client side.
instead of ILinkServiceLibrary we can use ILinkManager at client side. 
Other are common API.
 IChangeSet changeSet = (IChangeSet) repositoryItemService
                     .fetchItem(changeSetHandle, IRepositoryItemService.COMPLETE);

I replaced it with

IChangeSet changeSet = (IChangeSet) itemManager.fetchCompleteItem(changeSetHandle,itemManager.DEFAULT, monitor);
but at this line it is throwing null pointer exception
Could you please tell me about client API which will does similar thing.

 I think it should work :
 for (Object o : changeSet.changes()) {
     IChange change = (IChange) o;
     IVersionableHandle handle = change.item();
     IVersionable afterVersionable = workspaceManager.versionableManager().fetchCompleteState(handle, new SysoutProgressMonitor());
