Hi,

Is there a way to get the contents of a project in Jazz source control whose files can be found in a RTC change set via RTC/OSLC REST APIs?

From oslc_cm:ChangeRequest I can navigate to a scm:ChangeSet associated with it.
For example, here is a snapshot of a scm:ChangeSet obtained via a GET on

https://localhost:9443/jazz/resource/itemOid/com.ibm.team.scm.ChangeSet/_IrrpoXz5Ed-hkKjk2Khljw?_mediaType=text/xml

<scm>

<stateId>_IxVlt3z5Ed-hkKjk2Khljw</stateId>

<immutable>true</immutable>

<contextId>_Dp6kMdwTEd2jUupDpQV1Rw</contextId>

<modified>2010-06-21T05:52:12.187Z</modified>

<lastUpdatedDate>2010-06-21T05:52:12.125Z</lastUpdatedDate>

<modifiedBy>

<changes>

<internalId>_IuEPQnz5Ed-hkKjk2Khljw</internalId>

<kind>2</kind>

<before>_76M7OXz4Ed-hkKjk2Khljw</before>

<after>_ItwtRHz5Ed-hkKjk2Khljw</after>

<item>

</changes>

<component>

<owner>

<xComponentLink>

</scm>

However, I cannot navigate to access the component or the item of type "filesystem:FileItemHandle". Is this possible by using REST APIs?


Thanks in advance,

private void createLocalDump(IFolderHandle fHandle, ServiceConfigurationProvider configProvider, String parent) throws TeamRepositoryException, IOException{

		IScmService scmService = getService(IScmService.class);	

		IServerSideVersionedContentService serverVCService = getService(IServerSideVersionedContentService.class);

		FolderEntryReport[] feRpts = scmService.configurationChildEntriesMultiple(configProvider,

				new IFolderHandle[]{fHandle}, null, null);

			

		for(FolderEntryReport feRpt : feRpts){

			Map map = feRpt.getEntries();

			for(String child: (Set<String>)map.keySet()){

				System.out.println(child);

				IVersionableHandle vhandle = (IVersionableHandle) map.get(child);

				if(vhandle instanceof IFolderHandle){

					String childDir = parent + "/" + child;

					new File(childDir).mkdirs();

					createLocalDump((IFolderHandle)vhandle,configProvider,childDir);

				}

				else if(vhandle instanceof IFileItemHandle){

					IFileItem fileItem = (IFileItem)getVersionable(vhandle);

					ContentHash ch = ((IFileItem)fileItem).getContent().getHash();

					FileOutputStream fos = new FileOutputStream(new File(parent + "/" +

							fileItem.getName()));

					serverVCService.fetchContent(fileItem, ch, fos);	

					fos.close();

				}

			}

		}	

	} 

Here's some preliminary information:

This specifies the UUID of the versionable (folder, file or symbolic link)

<internalId>_IuEPQnz5Ed-hkKjk2Khljw</internalId>

These specify the states of the versionable

<before>_76M7OXz4Ed-hkKjk2Khljw</before>

<after>_ItwtRHz5Ed-hkKjk2Khljw</after>

If the versionable is a file item then it has content.

In RTC 3.0 (and probably RTC 2.0.0.2) , I believe that you can GET the content from the IFilesystemContentService, which lives at:

.../service/com.ibm.team.filesystem.service.internal.rest.IFilesystemContentService

It's header comment explains:

/**

 * Content service for Filesystem, which returns the contents of files given a

 * URIs of the form:

 * .../{workspaceItemId}/{componentItemId}/{fileNameOrFilePath}?itemId={fileItemId}&stateId={fileStateId}

 * 

 * The {fileNameOrFilePath} segment(s) are there only to cause the browser to offer an appropriate

 * file name on save.

 */

At the moment, I don't have any advice about how to get a workspaceItemId or the relevant componentItemId, though it might be the value of

<contextId>_Dp6kMdwTEd2jUupDpQV1Rw</contextId>

.

Shortly, I'll add another reply explaining how to use the oslc-scm capabilities that are being added to RTC 3.0
