How can I retrieve a list of attachments of a workitem
programmatically.

I know how to add an attachment but I don't know how to retrieve the
existing attachments of a existing workitem.

You would do it using the same IWorkItemReferences class used when adding
attachments:

IWorkItemReferences references= workingCopy.getReferences();
List<IReference> attachments=
references.getReferences(WorkItemEndPoints.ATTACHMENT);
for (IReference reference : attachments) {
IItemReference attachmentReference= (IItemReference) reference;
IAttachmentHandle attachmentHandle= (IAttachmentHandle)
attachmentReference.resolve();
}

Hi Patrick!

First of all thanks for your fast help.

Perhaps I should post my current code:

		// Query the Jazz repository for list of workitems

		auditableClient = (IAuditableClient) teamRepository

				.getClientLibrary(IAuditableClient.class);

		IQueryClient queryClient = (IQueryClient) teamRepository

				.getClientLibrary(IQueryClient.class);



		IQueryableAttribute attribute = QueryableAttributes.getFactory(

				IWorkItem.ITEM_TYPE).findAttribute(projectArea,

				IWorkItem.PROJECT_AREA_PROPERTY, auditableClient, null);

		Expression expression = new AttributeExpression(attribute,

				AttributeOperation.EQUALS, projectArea);

		IQueryResult<IResolvedResult<IWorkItem>> results = queryClient

				.getResolvedExpressionResults(projectArea, expression,

						IWorkItem.FULL_PROFILE);



		while (results.hasNext(null)) {



			IResolvedResult<IWorkItem> resolved = results.next(null);

			

			...

			

			// Getting existing attachments...

	

			IWorkItemWorkingCopyManager workingCopyManager = workItemClient.getWorkItemWorkingCopyManager();

			IWorkItemHandle foundWorkItem = workItemClient.findWorkItemById(resolved.getItem().getId(), IWorkItem.FULL_PROFILE, null);

			workingCopyManager.connect(foundWorkItem, IWorkItem.FULL_PROFILE, null);

			WorkItemWorkingCopy workingCopy = workingCopyManager.getWorkingCopy(foundWorkItem);

			

			IWorkItemReferences references = workingCopy.getReferences();

			List<IReference> attachments = references

					.getReferences(WorkItemEndPoints.ATTACHMENT);

			



			for (IReference reference : attachments) {

				

				IItemReference attachmentReference = (IItemReference) reference;

				IAttachmentHandle attachmentHandle = (IAttachmentHandle) attachmentReference

						.resolve();

				

			}

		}

But now I have some additional questions:
1. Why do I have to use a working copy of the workitem although I already have a reference to the workitem in my iteration?
2. How can I save the attachments to disk?

Do you have any idea? Thanks in advance!
Marcel.
