access outlook 365 inbox [duplicate]

I have a piece of Java code (see below), which has not been changed in a while and worked two weeks ago. When I run it now, I suddenly get an "AUTHENTICATE FAILED." I get the error on two different PCs, and I have validated that the credentials used still work when I log into may office365 mailbox using the browser.
Has something changed on the office365 side I should know of?
The error I get is:
javax.mail.AuthenticationFailedException: AUTHENTICATE failed.
at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:732)
at javax.mail.Service.connect(Service.java:366)

Digging deeper, the cause seems to be an A3 NO AUTHENTICATE failed. response (line 730 of javax.mail.IMAPStore).
The code I use is the following (using javax.mail version 1.6.2):

Again, this code worked perfectly two weeks ago, nothing was changed on my side and the credentials still work...
All suggestions are appreciated.

You must use OAuth2, legacy security may have been deprecated.
Works with Thunderbird for example.
Just see how to reactivate legacy auth or use OAuth2 with your java client.
#see https://learn.microsoft.com/fr-fr/exchange/troubleshoot/administration/cannot-connect-mailbox-pop-imap-outlook to reactivate legacy
PS : To use shared mailbox, you must user mailbox name as user, and OAuth2 user + password and MFA if needed during Auth part, all that instead of old way (user#domain\sharedmailbox + password)

Spring Stomp over Websocket: Stream large files

My SockJs client in webpage, sends message with a frame size of 16K. The message size limit is what determines the max size of the file that I can transfer.
Below is what I found in the doc.
/**
* Configure the maximum size for an incoming sub-protocol message.
* For example a STOMP message may be received as multiple WebSocket messages
* or multiple HTTP POST requests when SockJS fallback options are in use.
*
* <p>In theory a WebSocket message can be almost unlimited in size.
* In practice WebSocket servers impose limits on incoming message size.
* STOMP clients for example tend to split large messages around 16K
* boundaries. Therefore a server must be able to buffer partial content
* and decode when enough data is received. Use this property to configure
* the max size of the buffer to use.
*
* <p>The default value is 64K (i.e. 64 * 1024).
*
* <p><strong>NOTE</strong> that the current version 1.2 of the STOMP spec
* does not specifically discuss how to send STOMP messages over WebSocket.
* Version 2 of the spec will but in the mean time existing client libraries
* have already established a practice that servers must handle.
*/
public WebSocketTransportRegistration setMessageSizeLimit(int messageSizeLimit) {
this.messageSizeLimit = messageSizeLimit;
return this;
}
MY QUESTION:
Can I setup a partial messaging so that a file is transferred part by part and is not getting transferred as a single message as it is been done now?
Update:
Still looking for a solution with partial messaging
Meanwhile using HTTP now for large messages (which is file uploads/downloads in my application).

Can I setup a partial messaging so that a file is transferred part by part and is not getting transferred as a single message as it is been done now?
Yes. Here is the relevant Config from my Spring boot experimental project - basically UploadWSHandler is registered and WebSocketTransportRegistration.setMessageSizeLimit is set.
#Configuration
#EnableWebSocket
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer implements WebSocketConfigurer {
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(new UploadWSHandler(), "/binary");
}
#Override
public void configureWebSocketTransport(WebSocketTransportRegistration registration) {
registration.setMessageSizeLimit(50 * 1024 * 1024);
}
}
The UploadWShandler is as follows. Sorry too much code here - Key points
supportsPartialMessage which returns true.
handleBinaryMessage will be called multiple times with partial message so we need to assemble the bytes. So afterConnectionEstablished establishes an identity using the websocket URL query. But you don't have to use this mechanism. The reason why I choose this mechanism is to keep the client side simple so that I call webSocket.send(files[0]) only once i.e. I am not slicing the file blob object on the javascript side. (side point: I want to use plain websocket on client side - no stomp/socks)
The iternal client side chunking mechanism provides message.isLast() last message
For demo purposes I am writing this to file system and accumulating those bytes in memory with FileUploadInFlight but you don't have to do this and can stream somewhere else as you go.
public class UploadWSHandler extends BinaryWebSocketHandler {
Map<WebSocketSession, FileUploadInFlight> sessionToFileMap = new WeakHashMap<>();
#Override
public boolean supportsPartialMessages() {
return true;
}
#Override
protected void handleBinaryMessage(WebSocketSession session, BinaryMessage message) throws Exception {
ByteBuffer payload = message.getPayload();
FileUploadInFlight inflightUpload = sessionToFileMap.get(session);
if (inflightUpload == null) {
throw new IllegalStateException("This is not expected");
}
inflightUpload.append(payload);
if (message.isLast()) {
Path basePath = Paths.get(".", "uploads", UUID.randomUUID().toString());
Files.createDirectories(basePath);
FileChannel channel = new FileOutputStream(
Paths.get(basePath.toString() ,inflightUpload.name).toFile(), false).getChannel();
channel.write(ByteBuffer.wrap(inflightUpload.bos.toByteArray()));
channel.close();
session.sendMessage(new TextMessage("UPLOAD "+inflightUpload.name));
session.close();
sessionToFileMap.remove(session);
}
String response = "Upload Chunk: size "+ payload.array().length;
System.out.println(response);
}
#Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
sessionToFileMap.put(session, new FileUploadInFlight(session));
}
static class FileUploadInFlight {
String name;
String uniqueUploadId;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
/**
* Fragile constructor - beware not prod ready
* #param session
*/
FileUploadInFlight(WebSocketSession session) {
String query = session.getUri().getQuery();
String uploadSessionIdBase64 = query.split("=")[1];
String uploadSessionId = new String(Base64Utils.decodeUrlSafe(uploadSessionIdBase64.getBytes()));
System.out.println(uploadSessionId);
List<String> sessionIdentifiers = Splitter.on("\\").splitToList(uploadSessionId);
String uniqueUploadId = session.getRemoteAddress().toString()+sessionIdentifiers.get(0);
String fileName = sessionIdentifiers.get(1);
this.name = fileName;
this.uniqueUploadId = uniqueUploadId;
}
public void append(ByteBuffer byteBuffer) throws IOException{
bos.write(byteBuffer.array());
}
}
}

Issues in Apache CXF for getting server stacktrace in Exception_Exception

I have implemented Apache CXF WebService and trying to access WebService through Swings Application.
The problem that I am facing is CXF has created a class named Exception_Exception in client side from the WSDL. When an exception occurs in server side, the client Exception_Exception gets invokes but I don't receive the same stack trace of server in Exception_Exception stack trace.
Below is the class generated by CXF:
package com.abc.it.vcare.service;
import javax.xml.ws.WebFault;
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2-hudson-752-
* Generated source version: 2.2
*
*/
#WebFault(name = "Exception", targetNamespace = "http://service.vcare.it.abc.com/")
public class Exception_Exception
extends java.lang.Exception
{
/**
* Java type that goes as soapenv:Fault detail element.
*
*/
private com.axiom.it.vcare.service.Exception faultInfo;
/**
*
* #param message
* #param faultInfo
*/
public Exception_Exception(String message, com.axiom.it.vcare.service.Exception faultInfo) {
super(message);
this.faultInfo = faultInfo;
}
/**
*
* #param message
* #param faultInfo
* #param cause
*/
public Exception_Exception(String message, com.axiom.it.vcare.service.Exception faultInfo, Throwable cause) {
super(message, cause);
this.faultInfo = faultInfo;
}
/**
*
* #return
* returns fault bean: com.axiom.it.vcare.service.Exception
*/
public com.axiom.it.vcare.service.Exception getFaultInfo() {
return faultInfo;
}
}
Please help, what should I do to get the same StackTrace given in Server Exception in my client side Exception_Exception.
Thanks,
Jai G.

What version of CXF are you using? This is an old CXF issue that has been addressed in the most recent versions. Try using version 2.7.0 of CXF, that should solve the problem.

How to send an email using MS exchange server

I am trying to sent an email using my company's mail server. But I am getting the following exception
Caused by: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.1 Client was not authenticated
at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:959)
at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:583)
at javax.mail.Transport.send0(Transport.java:169)
at javax.mail.Transport.send(Transport.java:98)
Here is my sample code,
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", "example.server.com");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", "25");
// Get session
//Session session = Session.getDefaultInstance(props, null);
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username", "password");
}
});
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(from));
// Set the to address
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set the subject
message.setSubject("Hello JavaMail");
// Set the content
message.setText("Welcome to JavaMail");
// Send message
Transport.send(message);
What piece of code is wrong?
As as username and password , I am using my company's email address and password.

The 5.7.1 is probably caused by exchange and not your code. You may just need to enable relaying on the server. Either for anonymous users or from a certain IP address. I'm not an expert on Exchange but I have got this working before. Here is the last solution I tested that works:
If a 5.7.1 error is encountered when trying to send an email via SMTP on an exchange server when the user has been authenticated..
For ref the issue you just had was caused by a setting on the Exchange 2007 server – this would not normally be a problem on 2003 server
Fixed by doing below...
You can set this authentication setting via the GUI
In Server configuration / Hub Transport / Default <ServerName>
Right click, properties, Permission Groups
Check "Anonymous users" and then click OK
Obviously anon users is not too secure but you could see if this solves the problem.

When I will use a MS Exhange SMTP Server to send an email, I use the above maven dependency.
<dependency>
<groupId>com.microsoft.ews-java-api</groupId>
<artifactId>ews-java-api</artifactId>
<version>2.0</version>
</dependency>
For that reason I created a class that represents an email client for MS Exchange Servers. I use log4j for logging.

<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>

A working example,
// import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
ExchangeClient client = new ExchangeClient.ExchangeClientBuilder()
.hostname("webmail.domainOfWeb.com")
.exchangeVersion(ExchangeVersion.Exchange2010)
.domain("ActiveDirectoryDomain")
.username("ActiveDirectoryUsername")
.password("ActiveDirectoryPassword")
.recipientTo("recipient#whatever.com")
.recipientCc("recipient#whatever.com") // Ignore it in case you will not use Cc recipients.
.recipientBcc("recipient#whatever.com") // Ignore it in case you will not use Bcc recipients.
.attachments("/home/username/image.png") // Ignore it in case you will not use attachements.
.subject("Test Subject")
.message("Test Message")
.build();
client.sendExchange();

Mail.jar (Version 1.4.0) has a compatibility issue with MS Exchange Server and throws 530 5.7.1 Client was not authenticated, even when Username and password are configured.
Upgrading the mail API to 1.4.4 OR 1.4.7 should resolve the issue.
Mail API's 1.4.7 can be download from the following URL: http://www.oracle.com/technetwork/java/javamail/index.html

In some companies, the Exchange server SMTP support is disable and you cannot ask them to enable it. In these cases, a reasonable solution is this one:
http://davmail.sourceforge.net/

Simple Java Mail worked for me. The only thing you have to check is for correct hostname, username, port and password TransportStrategy.SMTP_TLS:
new Mailer(host, port, username, password, TransportStrategy.SMTP_TLS).sendMail(email);

I had to use javamail + exchange. The messages returned were helpless.
Thanks to the stack, I got some hints.
Add this to your code
props.put("mail.smtp.starttls.enable","true");
Think of adding the certificates of the machines used too.
To find them, just go to your browser, export them and import to the cacerts file in use.

Please use the following code parts instead of Transport.send(message);
MimeMessage message = new MimeMessage(session);
message.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect(host, "user", "pwd");
transport.sendMessage(message, message.getAllRecipients());
transport.close();
I have tested in the local and it is working

The ews-java-api package is at end of life.
From https://github.com/OfficeDev/ews-java-api
Starting July 19th 2018, Exchange Web Services (EWS) will no longer receive feature updates. While the service will continue to receive security updates and certain non-security updates, product design and features will remain unchanged. This change also applies to the EWS SDKs for Java and .NET. More information here: https://developer.microsoft.com/en-us/graph/blogs/upcoming-changes-to-exchange-web-services-ews-api-for-office-365/
