Saving the attachments to disk programmatically

Hi All,
Am using RTC 2002; Have a requirement of saving attachments on a workitem to disk programmatically; I did refer couple of postings in this forum and could not get any pointers from them.

Am getting a run time cast exception on running the code I have written. The exception looks something like below:

Exception in thread "main" java.lang.ClassCastException: com.ibm.team.workitem.common.internal.model.impl.AttachmentHandleImpl incompatible with com.ibm.team.workitem.common.model.IAttachment
at com.ibm.team.workitem.ide.ui.example.SaveAttachments.run(SaveAttachments.java:178)
at com.ibm.team.workitem.ide.ui.example.SaveAttachments.main(SaveAttachments.java:102)


snippet of the code I have written is pated below: 

 IWorkItemReferences fsrcReferences = srcWorkingCopy.getReferences();

		  

		  List<IReference> srcAttachments = fsrcReferences.getReferences(WorkItemEndPoints.ATTACHMENT); 

		  for (int i=0; i < srcAttachments.size(); i++) { 

			  IReference srcReference = srcAttachments.get(i);



			  IItemReference attachmentReference = (IItemReference) srcReference;

			  IAttachmentHandle attachmentHandle = (IAttachmentHandle) attachmentReference.resolve();

			  

			  IAttachment srcAttachment = (IAttachment) attachmentHandle;

			  String srcAttachmentName = srcAttachment.getName();

			  

			  FileOutputStream fos = null;

			try {

				fos = new FileOutputStream("C:\\temp\\" + srcAttachmentName);

			} catch (FileNotFoundException e1) {

				e1.printStackTrace();

			}

			  IContentManager cm= srcTeamRepository.contentManager(); 

			  cm.retrieveContent(srcAttachment.getContent(), fos, null);

			  

         }


Any pointers/ guidance would be of great help. Many thanks in advance.

Regards,
Mohan.

IAttachment srcAttachment = (IAttachment) attachmentHandle;

You cannot cast a handle to an item, you need to resolve it:

IAttachment srcAttachment =
srcRepository.itemManager().fetchCompleteItem(attachmentHandle,
IItemManager.DEFAULT, monitor);
