How to open each email in gmail? - java

Could you please help with follow?
I need to open each email that I have in my Inbox.
Get a content from it.
public void main() {
driver.get("https://mail.google.com");
// gmail login
driver.findElement(By.id("Email")).sendKeys("email");
driver.findElement(By.id("next")).click();
driver.findElement(By.id("Passwd")).sendKeys("password");
driver.findElement(By.id("signIn")).click();
List<WebElement> unreademeil = driver.findElements(By.xpath("//*[#class='zF']"));
// Mailer name for which i want to check do i have an email in my inbox
String MyMailer = "Команда Gmail";
// real logic starts here
for(int i=0;i<unreademeil.size();i++){
if(unreademeil.get(i).isDisplayed()==true){
if(unreademeil.get(i).getText().equals(MyMailer)){
System.out.println("Yes we have got mail form " + MyMailer);
break;
}else{
System.out.println("No mail form " + MyMailer);
}
}
}
//open a mail from the gmail inbox.
List<WebElement> a = driver.findElements(By.xpath("//*[#class='yW']/span"));
System.out.println(a.size());
for (int i = 0; i < a.size(); i++) {
System.out.println(a.get(i).getText());
if (a.get(i).getText().equals("Я")) //to click on a specific mail.
{
a.get(i).click();
System.out.println(driver.findElement(By.xpath("//*[#id=\":9v\"]/div[1]")).getText());
driver.navigate().back();
}
}
I've tried JavaMail API as well.
But it seems that I do something wrong in their code.
public static void bot() throws Exception {
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect("imap.gmail.com", "#gmail.com",
"password");
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
System.out.println("Total Message:" + folder.getMessageCount());
System.out.println("Unread Message:"
+ folder.getUnreadMessageCount());
Message[] messages = null;
boolean isMailFound = false;
Message mailFromGod= null;
//Search for mail from God
for (int i = 0; i < 5; i++) {
messages = folder.search(new SubjectTerm("t");
folder.getMessages());
//Wait for 10 seconds
if (messages.length == 0) {
Thread.sleep(10000);
}
}
for (Message mail : messages) {
if (!mail.isSet(Flags.Flag.SEEN)) {
mailFromGod = mail;
System.out.println("Message Count is: "
+ mailFromGod.getMessageNumber());
isMailFound = true;
}
}
String line;
StringBuffer buffer = new StringBuffer();
BufferedReader reader = new BufferedReader(
new InputStreamReader(mailFromGod
.getInputStream()));
while ((line = reader.readLine()) != null) {
buffer.append(line);
System.out.println(buffer);
String registrationURL = buffer.toString().split("http://www./?")[0]
.split("href=")[1];
System.out.println(registrationURL);
}
}
}
and try this
package Bots;
import javax.mail.*;
import java.util.Properties;
public class checkemail {
public static void check(String host, String storeType, String user,
String password)
{
try {
//create properties field
Properties properties = new Properties();
properties.put("mail.pop3.host", host);
properties.put("mail.pop3.port", "995");
properties.put("mail.pop3.starttls.enable", "true");
Session emailSession = Session.getDefaultInstance(properties);
//create the POP3 store object and connect with the pop server
Store store = emailSession.getStore("pop3s");
store.connect(host, user, password);
//create the folder object and open it
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
// retrieve the messages from the folder in an array and print it
Message[] messages = emailFolder.getMessages();
System.out.println("messages.length---" + messages.length);
for (int i = 0, n = messages.length; i < n; i++) {
Message message = messages[i];
System.out.println("---------------------------------");
System.out.println("Email Number " + (i + 1));
System.out.println("Subject: " + message.getSubject());
System.out.println("From: " + message.getFrom()[0]);
System.out.println("Text: " + message.getContent().toString());
//System.out.println("Message" + message.getDescription().toString());
}
//close the store and folder objects
emailFolder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
String host = "pop.gmail.com";// change accordingly
String mailStoreType = "pop3";
String username = "test#gmail.com";// change accordingly
String password = "test";// change accoredingly
check(host, mailStoreType, username, password);
}
}
Result:
...
Email Number 7
Subject: test
From: Google
Text: javax.mail.internet.MimeMultipart#612fc6eb
Email Number 8
Subject: test
From: Google
Text: javax.mail.internet.MimeMultipart#1060b431
but how to get normal text from the message

message.getContent().toString()
Above code works for plain text for multipart messages please include below piece of code in you for loop.
Multipart multipart = (Multipart) message.getContent();
for (int j = 0; j < multipart.getCount(); j++) {
BodyPart bodyPart = multipart.getBodyPart(j);
System.out.println("Body: "+bodyPart.getContent());
content= bodyPart.getContent().toString();
System.out.println(content);
}
Lets update if your issue resolves by this.

I've modified code a bit. Everything seems to be working as expected.

File transfer Client to Client in JAVA

I need to implement a program to transfer files. I decided to make it using a chat template I've made about 1 month ago so I would have a chat with file transfer option.
The transfer should follow the following points:
1- Server only keeps a list of all files provided by connected clients (No file are actually located in the server, only their names)
2- Client "1" requests file "A" then:
if file "A" is located ONLY in client "2", then client "2" should send 100% of the file to client "1"
if file "A" is located in client "2" and client "3" also has file "A", then client "2" should send 50% of the file to client "1" and client "3" should send the other 50%.
(if the file is located in 4 clients it should be 25% each....and so it goes...)
I've already managed to make the server find out which client is requesting the file and which clients have it. But now I'm stuck, I don't know how to make the transfer.
Could someone give me an example of how to do it? or point me through the right direction?
[I'm aware my code has some flaws and I will fix it later, right now I need to make the transfer happen before working on fixes, so please, unless it's related, try to focus on that]

I was able to make a transfer between two clients easily with the information provided and a little research on stackOverflow to understand more about out/inputStreams!
This post also helped me a lot: Sending a file with Java Sockets, losing data
next step is the shared transfer

Each one of your threads creates its own Login object.
Therefore, synchronization has no effect, because each thread synchronizes on a different instance of your Login object.
In order to achieve the desired behavior you have to instantiate only one Login object and pass it to all your threads to use.

Retrieving emails from Latest to oldest Java Mail API

private Folder inbox = null;
private String userName = "xxx#gmail.com"; //

properties.setProperty("mail.host", "imap.gmail.com");

In the above code I am able to get emails from oldest to newest on my console from gmail. However I would want it to loop from newest to oldest. Is there any way I could get this achieved. Please Help :)
I don't think there's a parameter or method for this in the JavaMail API. You have to reverse the messages array yourself, e.g. by including the Commons.Lang library:
messages = ArrayUtils.reverse(messages);
or iterating over it in the other direction:
for (int i = messages.length - 1; i >= 0; i--) {
Message message = messages[i];

JavaMail : Folder.hasNewMessages() and .getMessageCount() don't seem to work properly

I have this simple code to perdiodically access a pop3 server and check if there are new messages in the inbox folder
public static void main(String[] args) {
try {
String storeType = "pop3";
String host = "...";
int port = ...;
String user = "...";
String psw = "...";
//
int delay = 1;
long mins = 200 * 60 * delay;
firstAccess = true;
Properties properties = new Properties();
properties.put("mail.pop3.host", host);
properties.put("mail.pop3.user", user);
properties.put("mail.pop3.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.put("mail.pop3.port", port);
RomasAuthenticator r = new RomasAuthenticator(user, psw);
Session session = Session.getDefaultInstance(properties, r);
POP3Store emailStore = (POP3Store) session.getStore(storeType);
emailStore.connect(host, port, user, psw);
Folder emailFolder = emailStore.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
while (true) {
if (checkInbox(emailFolder)) {
//prepara la notifica per il voice_service
System.out.println("mes!");
}
firstAccess = false;
Thread.sleep(mins);
}
} catch (Exception ex) {
//return null;
}
}
private static boolean checkInbox(Folder inbox_folder) throws MessagingException, IOException {
System.out.println("checking");
boolean res = false;
try {
int email_actual_count = inbox_folder.getMessageCount();
if (email_actual_count > email_prev_count /*or hasNewMessages()*/) {
if (!firstAccess) {
res = true;
}
}
//bisogna aggiornare comunque email_count in caso siano stati cancellati messaggi
email_prev_count = email_actual_count;
}
catch (Exception e) {
e.printStackTrace();
}
return res;
}
Both getMessageCount() and hasNewMessages() do not work, because the first always returns the same number of messages, and the second always returns false. What's that I'm doing wrong?
I don't want to use a messagelistener because this code will run on a robot with really low performances..
thanks everyone
The JavaMail FAQ explains why these features don't work with the POP3 protocol.
