Investigate file locking in server API

Question

Hi

I have a need for investigating if files in a changeset are locked on delivery. In an operation advisor, that is triggered on delivery, i shall find out, if any of the files in the delivering changeset are locked on the receiving stream.

My next need is to be able to lock files, that are delivered. I figure it done in an operation participant also triggered on delivery.

It's not easy to find anything about how to lock/unlock files by the serverside API.

Regards

Erling

The client side API is outlined in another forum post: SCM Locking API.

It would probably be useful to look at that, <tt>IWorkspaceManager.applyLockOperations</tt> will call the server side <tt>IScmService.updateLocks</tt> and <tt>IWorkspaceManager.findLocks</tt> calls the server side <tt>IScmQueryService.findLocks</tt>

I'm still having trouble making this work. My code is:

IScmService scmService = getService(IScmService.class);

    LockParameter lockParameter = ScmDtoFactory.eINSTANCE.createLockParameter();

    WorkspaceLocks wLocks = ScmDtoFactory.eINSTANCE.createWorkspaceLocks();
    wLocks.setWorkspace((IWorkspaceHandle) deliverData.getDestWorkspace().getItemHandle());

    ComponentLocks cLocks = ScmDtoFactory.eINSTANCE.createComponentLocks();
    cLocks.setComponent(changeSet.getComponent());

    ContributorLocks contLocks = ScmDtoFactory.eINSTANCE.createContributorLocks();
    contLocks.setContributor(changeSet.getAuthor());
    List<IChange> changes =  changeSet.changes();
    for (IChange iChange : changes) {
        IVersionableHandle versionableHandle = iChange.afterState(); //tried getting afterstate(), no difference
        if (versionableHandle.getItemType().getName().equals("FileItem")){
            contLocks.getVersionables().add(iChange.afterState());
        }
    }

    cLocks.getContributorLocks().add(contLocks);
    wLocks.getComponentLocks().add(cLocks);     
    lockParameter.getToAcquire().add(wLocks);

    scmService.updateLocks(lockParameter, null);

I don't get stacktraces, just an error.
