Synchronization of two workspaces in same RTC repository

I am working currently on a project using RTC (Rational Team Concert) through Plain Java API.
I have a online-repository on which I have a main stream named Sample_ROOT. From this stream I want to create another one named Sample_Client_Application. The Sample_Client_Application should have all components of Sample_ROOT and whenever changes are committed in Sample_ROOT, they have to be pushed into Sample_Client_Application.
I tried to implement all the process described above in eclipse with RTC Plain Java API with the code below.
/*
parentStream : represents Sample_ROOT
appStream : represents DTO of Sample_Client_Application
projectStreams is a map of projects with their workspaces : HashMap<String, List<IWorkspaceHandle>>
*/
public IWorkspaceConnection createAppInTeamAreas(String parentStream, StreamDTO appStream)
throws TeamRepositoryException {
monitor.println("Getting Workspace");
IWorkspaceManager workspaceManager = SCMPlatform.getWorkspaceManager(repository);
IWorkspaceConnection workspaceConnection = null;
Optional<IWorkspaceHandle> handle = projectStreams.get(appStream.getProjectName()).stream().filter(xHandle -> {
IWorkspace workspace = null;
try {
workspace = (IWorkspace) repository.itemManager().fetchCompleteItem(xHandle, IItemManager.DEFAULT,
null);
} catch (TeamRepositoryException e) {
e.printStackTrace();
}
return workspace != null && workspace.getName() == parentStream;
}).findFirst();
if (handle.isPresent()) {
IWorkspace parentWorkSpace = null;
try {
parentWorkSpace = (IWorkspace) repository.itemManager().fetchCompleteItem(handle.get(),
IItemManager.DEFAULT, null);
} catch (TeamRepositoryException e) {
e.printStackTrace();
return null;
}
IWorkspaceConnection parentConn = workspaceManager.getWorkspaceConnection(handle.get(), monitor);
List<IComponentHandle> parentComps = (List<IComponentHandle>) parentConn.getComponents();
IWorkspaceConnection childConn = null;
IItemManager itemManager = repository.itemManager();
for (IComponentHandle parentCompHandle : parentComps) {
IItemHandle itemHandle = (IItemHandle) parentCompHandle;
IComponent parentComp = (IComponent) itemManager.fetchCompleteItem(itemHandle, IItemManager.DEFAULT,
monitor);
monitor.println(String.format("Component name : %s", parentComp.getName()));
childConn = createAndAddSycrhronizedComponents(parentWorkSpace, parentComp, parentConn, appStream,
childConn);
}
workspaceConnection = childConn;
}
return workspaceConnection;
}
private IWorkspaceConnection createAndAddSycrhronizedComponents(IWorkspace parentStream, IComponent parentComp,
IWorkspaceConnection parentConnection, StreamDTO childStream, IWorkspaceConnection childConnection) {
IWorkspaceManager workspaceManager = SCMPlatform.getWorkspaceManager(repository);
IWorkspaceConnection workspaceConnection = null;
try {
if (childConnection == null) {
workspaceConnection = workspaceManager.createWorkspace(repository.loggedInContributor(),
childStream.getName(), childStream.getDescription(), monitor);
} else {
workspaceConnection = childConnection;
//Set flow for the newly created repository
IFlowTable flowTarget=workspaceConnection.getFlowTable().getWorkingCopy();
flowTarget.addDeliverFlow(parentStream, repository.getId(), repository.getRepositoryURI(), parentConnection.getComponents(), "Scoped");
flowTarget.addAcceptFlow(parentStream, repository.getId(), repository.getRepositoryURI(), parentConnection.getComponents(), "Scoped");
flowTarget.setCurrent(flowTarget.getDeliverFlow(parentStream));
flowTarget.setCurrent(flowTarget.getAcceptFlow(parentStream));
flowTarget.setDefault(flowTarget.getDeliverFlow(parentStream));
flowTarget.setDefault(flowTarget.getAcceptFlow(parentStream));
workspaceConnection.setFlowTable(flowTarget, monitor);
//Add the components to the workspace
List<Object> componentsToBeAdded=new ArrayList<>();
componentsToBeAdded.add(workspaceConnection.componentOpFactory().addComponent(parentComp, true));
workspaceConnection.applyComponentOperations(componentsToBeAdded, monitor);
//Accept stream changes to local repository
IChangeHistorySyncReport streamChangeHistorySyncReport=workspaceConnection.compareTo(parentConnection, WorkspaceComparisonFlags.INCLUDE_BASELINE_INFO, Collections.EMPTY_LIST, null);
workspaceConnection.accept(AcceptFlags.DEFAULT, parentConnection, streamChangeHistorySyncReport, streamChangeHistorySyncReport.incomingBaselines(parentComp), streamChangeHistorySyncReport.incomingChangeSets(parentComp), monitor);
}
} catch (TeamRepositoryException e) {
e.printStackTrace();
}
return workspaceConnection;
}
Sample_Client_Application is created successfully but it has no components. Can anyone help me Please ?

How to get file list of an Artifactory folder sorted by last modified stamp from Java client

I am trying to get last modified time stamp on Artifactory file item, but it is coming as null.
What am I doing wrong with this function?
public static List<File> listChildren(RepositoryHandle aRepo, String folder, FileFilter filter)
{
List<File> children = null;
if (null == aRepo || null == folder || folder.length() <= 0)
return null;
try
{
folder = FilenameUtils.normalizeNoEndSeparator(folder, true);
ItemHandle folderItem = aRepo.folder(folder);
Folder folderInfo = folderItem.info();
List<Item> itemChildren = folderInfo.getChildren();
if (null == itemChildren)
return null;
children = new ArrayList<>(itemChildren.size());
String name;
File fileItem;
for(Item curItem: itemChildren)
{
fileItem = new File(curItem.getUri());
Date timeStamp = curItem.getLastModified(); // This is coming as null
fileItem.setLastModified(curItem.getLastModified().getTime());
name = fileItem.getName();
if (null != name)
{
if (null == filter ||
filter.accept(fileItem))
children.add(fileItem);
}
}
// Sort the list by last modified stamp so that the oldest is at the front
Collections.sort(children, Comparator.comparingLong(File::lastModified));
}
catch (Throwable ex)
{
ex.printStackTrace();
}
return children;
}

Below is modified version that gave me sorted list.
public static List<String> listChildren(RepositoryHandle aRepo, String folder, FileFilter filter)
{
List<String> children = null;
if (null == aRepo || null == folder || folder.length() <= 0)
return null;
try
{
folder = FilenameUtils.normalizeNoEndSeparator(folder, true);
ItemHandle folderItem = aRepo.folder(folder);
Folder folderInfo = folderItem.info();
List<Item> itemChildren = folderInfo.getChildren();
if (null == itemChildren)
return null;
List<org.jfrog.artifactory.client.model.File> itemExtChildren = new ArrayList<>();
for(Item curItem: itemChildren)
{
ItemHandle hItem = aRepo.file(folder+curItem.getUri());
if (null == hItem)
continue;
org.jfrog.artifactory.client.model.File aFile = hItem.info();
itemExtChildren.add(aFile);
}
Collections.sort(itemExtChildren, (org.jfrog.artifactory.client.model.File f1, org.jfrog.artifactory.client.model.File f2) ->
f1.getLastModified().compareTo(f2.getLastModified()));
children = new ArrayList<>(itemChildren.size());
String name;
for(Item curItem: itemExtChildren)
{
name = curItem.getName();
if (null != name)
{
if (null == filter ||
filter.accept(new File(name)))
children.add(name);
}
}
}
catch (Throwable ex)
{
}
return children;
}

Google API v3 checking exist folder by passing folder name

I'm using google API v3 for check exist folder. If folder does not exist, then create the new folder. This is my code for creating folder
private void createFolderInDrive() throws IOException {
boolean existed = checkExistedFolder("MyFolder");
if (existed = false) {
File fileMetadata = new File();
fileMetadata.setName("MyFolder");
fileMetadata.setMimeType("application/vnd.google-apps.folder");
File file = mService.files().create(fileMetadata)
.setFields("id")
.execute();
System.out.println("Folder ID: " + file.getId());
Log.e(this.toString(), "Folder Created with ID:" + file.getId());
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(),
"Folder is existed already", Toast.LENGTH_SHORT).show();
}
}
and here is the code for checking exist file
private boolean checkExistedFolder(String folderName) {
//File file = null;
boolean existedFolder = true;
// check if the folder exists already
try {
//String query = "mimeType='application/vnd.google-apps.folder' and trashed=false and title='" + "Evacuation Kit" + "'";
String query = "mimeType='application/vnd.google-apps.folder' and trashed=false and name='Evacuation Kit'";
// add parent param to the query if needed
//if (parentId != null) {
//query = query + " and '" + parentId + "' in parents";
// }
Drive.Files.List request = mService.files().list().setQ(query);
FileList fileList = request.execute();
if (fileList.getFiles().size() == 0 ) {
// file = fileList.getFiles().get(0);
existedFolder = false;
}
} catch (IOException e) {
e.printStackTrace();
}
return existedFolder;
fileList.getFiles().size() keep returning 3, even there is no folder on g drive. Can you guys tell me where am I doing wrong?

In the code you show, checkExistedFolder is always looking for the name "Evacuation Kit" and not using the argument folderName. Maybe this is the main reason you're always getting 3 from fileList.getFiles().size().
Also there's an assignment in if (existed = false), you should use if ( false == existed ) -using the static value in the left side of the comparison helps avoiding such mistakes-, or if (!existed). Note that it's important to check the nextPageToken when calling Files:list to check if there is more pages to look for the file. See more here https://developers.google.com/drive/api/v3/reference/files/list and Create folder if it does not exist in the Google Drive

This code will check if folder exist on drive. if exists, it will return id else create folder and returns id.
private DriveFile file;
GoogleApiClient mGoogleApiClient;
#Override
public void onConnected(#Nullable Bundle bundle) {
Log.e(TAG, "connected");
new Thread(new Runnable() {
#Override
public void run() {
DriveId Id = getFolder(Drive.DriveApi.getRootFolder(mGoogleApiClient).getDriveId(), "FOLDER_NAME");
Log.e(TAG, "run: " + Id);
}
}).start();
}
DriveId getFolder(DriveId parentId, String titl) {
DriveId dId = null;
if (parentId != null && titl != null) try {
ArrayList<Filter> fltrs = new ArrayList<>();
fltrs.add(Filters.in(SearchableField.PARENTS, parentId));
fltrs.add(Filters.eq(SearchableField.TITLE, titl));
fltrs.add(Filters.eq(SearchableField.MIME_TYPE, DriveFolder.MIME_TYPE));
Query qry = new Query.Builder().addFilter(Filters.and(fltrs)).build();
MetadataBuffer mdb = null;
DriveApi.MetadataBufferResult rslt = Drive.DriveApi.query(mGoogleApiClient, qry).await();
if (rslt.getStatus().isSuccess()) try {
mdb = rslt.getMetadataBuffer();
if (mdb.getCount() > 0)
dId = mdb.get(0).getDriveId();
} catch (Exception ignore) {
} finally {
if (mdb != null) mdb.close();
}
if (dId == null) {
MetadataChangeSet meta = new MetadataChangeSet.Builder().setTitle(titl).setMimeType(DriveFolder.MIME_TYPE).build();
DriveFolder.DriveFolderResult r1 = parentId.asDriveFolder().createFolder(mGoogleApiClient, meta).await();
DriveFolder dFld = (r1 != null) && r1.getStatus().isSuccess() ? r1.getDriveFolder() : null;
if (dFld != null) {
DriveResource.MetadataResult r2 = dFld.getMetadata(mGoogleApiClient).await();
if ((r2 != null) && r2.getStatus().isSuccess()) {
dId = r2.getMetadata().getDriveId();
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return dId;
}

The code working for me with updated API on Kotlin:
override fun createFolder(name: String): Task<GoogleDriveFileHolder> {
check(googleDriveService != null) { "You have to init Google Drive Service first!" }
check(search(name, FOLDER_MIME_TYPE).not()){"folder already exist"}
return Tasks.call<GoogleDriveFileHolder>(
mExecutor,
Callable<GoogleDriveFileHolder> {
val metadata = File()
.setMimeType(FOLDER_MIME_TYPE)
.setName(name)
GoogleDriveFileHolder(
googleDriveService!!.files()
.create(metadata)
.setFields("id")
.execute() ?: throw IOException("Null result when requesting file creation.")
)
})
}
private fun search(name: String, mimeType:String): Boolean {
var pageToken: String? = null
do {
val result: FileList =
googleDriveService!!
.files()
.list()
.setQ("mimeType='$FOLDER_MIME_TYPE'")
.setSpaces("drive")
.setFields("nextPageToken, files(id, name)")
.setPageToken(pageToken)
.execute()
for (file in result.files) {
Log.d(TAG_UPLOAD_FILE , "Found file: %s (%s)\n ${file.name}, ${file.id} ")
if (name == file.name) return true
}
pageToken = result.nextPageToken
} while (pageToken != null)
return false
}
private const val FOLDER_MIME_TYPE= "application/vnd.google-apps.folder"

Realm findfirst() is returning null

realm newbie here and facing a problem in my project. So what I want to achieve is that, in my app when I click a photo I am saving a realm object inside my database as well as caching the image locally to be used later. Here is the code for both:
#Override
public void onPhotoSelected(PXImage photo) {
PXComposition composition = null;
PXPhoto photoParent = null;
for (PXComposition pxComposition : mSession.getCompositions()) {
if (pxComposition.getItems() == null || pxComposition.getItems().size() < 1)
continue;
for (PXPhoto item : pxComposition.getItems()) {
if (item.getImage().getOriginalPath().equals(photo.getOriginalPath())) {
composition = pxComposition;
photoParent = item;
break;
}
}
}
if (composition == null && photo.isSelected()) {
mRealm.beginTransaction();
String uuid = mSession.addPhoto(photo).getUuid();
mRealm.commitTransaction(); // IMPORTANT to commit transaction. ContentDownloadTask requires PXImage to be written in Realm.
ThreadUtils.getDefaultExecutorService().submit(new ContentDownloadTask(this, photo.getOriginalPath(), uuid));
} else if (composition != null && !photo.isSelected()) {
mRealm.beginTransaction();
if (photoParent.getImage().isDownloaded()) // FIXME What if not copied yet ???
FileUtils.deleteFile(photoParent.getImage().getApplicationPath());
mSession.removePhoto(photoParent);
mRealm.commitTransaction();
}
onCheckChanged(photo);
App.log().v("SESSION", mSession.toString());
}
This is where click events on the photo are handled. After the selection click I am calling ThreadUtils.getDefaultExecutorService().submit(new ContentDownloadTask(this, photo.getOriginalPath(), uuid)); to cache the image locally. Here is the code for the ContentDownloadTask:
public class ContentDownloadTask implements Callable<Void> {
private String id;
private String path;
private Context context;
private Realm mRealm;
public static final String TAG = "ContentDownloadTask";
private static final String DIR_EXTERNAL_NAME = "Local";
private static final String FILE_EXTENSION = ".jpg";
public ContentDownloadTask(Context context, String path, String id) {
this.path = path;
this.id = id;
this.context = context;
}
#Override
public Void call() throws Exception {
try {
Log.d(TAG, "Copying From " + path);
//create output directory if it doesn't exist
final File file = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
if (file == null) {
throw new IllegalStateException("Failed to get external storage files directory");
} else if (file.exists()) {
if (!file.isDirectory()) {
throw new IllegalStateException(file.getAbsolutePath() +
" already exists and is not a directory");
}
} else {
if (!file.mkdirs()) {
throw new IllegalStateException("Unable to create directory: " +
file.getAbsolutePath());
}
}
File to = new File(file, DIR_EXTERNAL_NAME);
if (to.exists()) {
if (!to.isDirectory()) {
throw new IllegalStateException(file.getAbsolutePath() +
" already exists and is not a directory");
}
} else if (!to.mkdirs()) {
throw new IllegalStateException("Unable to create directory: " +
file.getAbsolutePath());
}
to = new File(to, fileName(this.id));
if (!to.exists())
to.createNewFile();
InputStream in = null;
if (PackageUtils.isContentUri(path)) {
Uri uri = PackageUtils.toUri(path);
in = context.getContentResolver().openInputStream(uri);
} else {
File from = new File(this.path);
in = new FileInputStream(from);
}
OutputStream out = new FileOutputStream(to);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
mRealm = Realm.getDefaultInstance();
PXImage image = mRealm.where(PXImage.class).equalTo("uuid", this.id).findFirst();
if (image == null) {
to.delete();
throw new Exception("Photo Not Found ID: " + this.id);
}
mRealm.beginTransaction();
image.setApplicationPath(to.getPath());
mRealm.commitTransaction();
mRealm.close();
Log.d(TAG, "Complete Copied From " + path + " To " + to.getAbsolutePath());
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
return null;
}
Now the null is returned at this statement: PXImage image = mRealm.where(PXImage.class).equalTo("uuid", this.id).findFirst();. Basically here I need to save the application path of the image that I cached locally inside the realm object. But it's returning null. Also this not happening every time I click the photos. This only happens sometimes and the error is not reproducible. Any kind of help will be appreciated. I have already checked the following duplicate questions:
first
second
third
fourth
public PXPhoto addPhoto(PXImage image) {
PXComposition composition = null;
PXPhoto photo = null;
boolean isLandscape = false;
int photosPerItem = getProduct().getSelectedPhotosPerItem();
switch (getProduct().getRootShortCode()) {
case Product.CategoryType.SQUARES:
case Product.CategoryType.CLASSIC:
case Product.CategoryType.WALLOGRAPHS:
case Product.CategoryType.SIGNATURES:
case Product.CategoryType.MOSAIC:
setLayoutType(image.isLandscape() ? C.LayoutType.LANDSCAPE.ordinal() : C.LayoutType.PORTRAIT.ordinal());
composition = PXComposition.initializeNewComposition(this);
photo = PXPhoto.initializePhoto(image);
break;
case Product.CategoryType.PANORAMA:
composition = PXComposition.initializeNewComposition(this);
photo = PXPhoto.initializePhoto(image);
break;
case Product.CategoryType.STRIPS:
case Product.CategoryType.POSTERS:
if (getCompositions() == null || getCompositions().size() == 0
|| (getProduct().getRootShortCode().equals(Product.CategoryType.STRIPS) &&
getCompositions().last().getItems().size() % photosPerItem == 0))
composition = PXComposition.initializeNewComposition(this);
else
composition = getCompositions().last();
photo = PXPhoto.initializePhoto(image);
break;
}
composition.addItem(photo);
composition.updateComposition();
if (!composition.isManaged()) {
Realm realm = Realm.getDefaultInstance();
composition = realm.copyToRealmOrUpdate(composition);
realm.close();
photo.setComposition(composition);
addComposition(composition);
} else
photo.setComposition(composition);
return photo;
}
EDIT:
uuid generation:
public PXPhoto() {
this.uuid = UUID.randomUUID().toString();
this.autoEnhance = false;
this.zoom = 1;
}

Error while running customized java class

I have created a sequence file out of directory and then given index according to groups I want so that I can create groups using that index. This groups are then given one by one to my customized java class which gives information based on the file present in the group.
My problem is that some time it runs perfectly but some time gives different errors like null pointer exception, data type of field not found.
The problem is may be due to size of group. Because I am creating folder based group and then do the fetches the information from that folder inside my customized jar.
So how can I resolve this issue?
