createNewFile() not working and image not being stored - java

I am trying to save the images in my local machine and its information in the database. But no data is being inserted into the database. The file is being created but their is no content (is of 0 bytes).
I am using hibernate and spring mvc REST API. I am receiving data from an angular 7 app. The program is running on live server but not on my local machine.
On the local server I get this error and response
POST

The problem actually was with PosixFilePermission class as this class only works with Linux based operating systems.
When used readAttributes() method it gave error as Linux has its own methods to get file attributes and windows has its own.

Get LDAP User information from HttpServerletRequest in Jboss

My team is migrating a java application from Weblogic to Jboss, when the user has consumed the app, this calls the method getUserFromSession.
The problem is when we get ldap information because this code does not work in Jboss the return error is
java.lang.NoSuchMethodException: io.undertow.servlet.spec.HttpSessionImpl.getInternalAttribute(java.lang.String)
The code to change is as follows, can you help me with some option to get that information something similar to what is currently in place for weblogic
public static UserBean getUserFromSession(HttpServletRequest request) throws SessionExpiredException {
try {
Method methodSession = request.getSession().getClass().getMethod("getInternalAttribute", String.class);

if (authUser == null) {
attempts++;

}
}
if (authUser != null) {

Spring Rest API TransactionSystemException

I'm very new in spring development because I'm not a back developer.
I create a back to manage sports training.
I has several times a TransactionSystemException like
Exceptionorg.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Error while committing the transaction
I don't understand what it mean.
I have a class Person who contains a Coordinates object on #OneToOne relation.
Each class have a Service class that has a method of adding.
In PersonService's add method, I call the Coordinates add method which save and return saved object.
This is the add method of PersonClass
public ResponseService<ObjectCreatedModel<UUID, PersonneMorale>> add(PersonneMorale personneMorale) {
String messageErreur = TAG + " - add - ";
StatusReturn status = StatusReturn.ERROR;
String message = null;
ObjectCreatedModel<UUID, PersonneMorale> objectCreatedModel = null;
if (personneMorale != null) {
if (personneMorale.getId() == null) {
personneMorale.setId(UUID.randomUUID());
try {
// Gestion des coordonnees
ResponseService<ObjectCreatedModel<UUID, Coordonnees>> responseServiceCoordonnees =
coordonneesService.add(personneMorale.getCoordonnees());
if (responseServiceCoordonnees.isSuccess() || responseServiceCoordonnees.exist()) {
ResponseService<Coordonnees> responseServiceCoordonneesGet = coordonneesService
.getOne(responseServiceCoordonnees.getObjectReturn().getId());
Coordonnees coordonnees = responseServiceCoordonneesGet.getObjectReturn();
personneMorale.setCoordonnees(coordonnees);
personneMorale = personneMoraleRepository.save(personneMorale);
if (personneMorale != null) {
status = StatusReturn.SUCCESS;
objectCreatedModel = new ObjectCreatedModel<>(personneMorale.getId(), null);
} else {
message = messageErreur + StringResource.E_OCCURRED;
}
} else {
status = responseServiceCoordonnees.getStatusReturn();
message = responseServiceCoordonnees.getMessage();
}
} catch (ConstraintViolationException violationException) {
status = StatusReturn.EXCEPTION;
message = messageErreur + ConstraintViolationReader.extractException(violationException);
} catch (Exception ex) {
status = StatusReturn.EXCEPTION;
message = messageErreur + ex.toString();
}
} else {
message = messageErreur + StringResource.E_MUST_NULL;
}
} else {
message = messageErreur + StringResource.E_SET_PARAMETER;
}
return new ResponseService<>(status, message, objectCreatedModel);
}
This is the add method of CoordinatesService
public ResponseService<ObjectCreatedModel<UUID, Coordonnees>> add(Coordonnees coordonnees) {
StatusReturn status = StatusReturn.ERROR;
String message = "";
ObjectCreatedModel<UUID, Coordonnees> objectCreatedModel = null;
if (coordonnees != null) {
if (coordonnees.getIdCoordonnees() == null) {
try {
coordonnees.setIdCoordonnees(UUID.randomUUID());
Coordonnees coordonneesBase = coordonneesRepository.save(coordonnees);
if (coordonneesBase != null) {
status = StatusReturn.SUCCESS;
objectCreatedModel = new ObjectCreatedModel<>(coordonneesBase.getIdCoordonnees(), null);
} else {
message = StringResource.E_ERROR_OCCURRED;
}
} catch (ConstraintViolationException violationException) {
status = StatusReturn.EXCEPTION;
message = "Exception" + ConstraintViolationReader.extractException(violationException);
} catch (Exception ex) {
status = StatusReturn.EXCEPTION;
message = "Exception" + ex.toString();
}
} else {
message = "Coordonnées" + ErrorsString.ERROR_COMMON_ID_MUST_BE_EMPTY;
}
} else {
message = ErrorsString.ERROR_COORDINATES_MANDATORY;
}
return new ResponseService<>(status, message, objectCreatedModel);
}
The error occurs when CoordinatesService try to save coordinates and pass to the catch (Exception e)
Could you help me to understand what Transaction error mean with an example like my code please ?

Unable to upload a file through multipart form data from java as well as postman

I have been trying to upload a file from java as well as postman. But I am unable to upload. The server is giving back the response as 200 Ok. But, the file is not being uploaded.
API Details:
I have an API for uploading file as "FileExplorerController". This API has a method "upload()" to upload the files. Url to access this method is"/fileupload". The API is working fine if I upload a file through HTML UI.
But I am trying to upload using Java. I have tried using Postman as well.

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.

The code working for me with updated API on Kotlin:

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"
