At first, oracle change this site a lot. I logged into this site after a long time and I was amazed to see the new changes. Moving onto the the question.
I am developing a spring mvc web application. The problem is when I send email, let say to more than 4 person, the program hangs for a while. Some friend told me to use thread pool to solve this. What is the general practice for handling this kind of situation?
I am trying send email .So I have downloaded javaEE and javamail jar files and added buildpath.And wrote this code below .But I am getting this exception.
Exception in thread "main" java.lang.RuntimeException: javax.mail.AuthenticationFailedException: 534-5.7.14 <https://accounts.google.com/ContinueSignIn?sarp=1&scc=1&plt=AKgnsbskV

What am i missing here.

final String username = "mymail@gmail.com";
final String password = "mypass";
Properties props = new Properties();

I have two programs that I'll post below, one is a Server and the other is a Client. The ChatServer runs once and many clients can run ChatClient from separate computers and talk together in their GUI's. The the client program comes with two buttons, one that's simulates the sending of a message to a single user ; "Send Message To User", and one that just generally sends a message ; "Send Message To All". Although now the Clients on the server seem to be able to selectively send messages to an individual by giving the recipient name, all the clients can see that message, which is not exact what I am aiming for. What I am going for is having the "Send Message To User" button click to send a message to the named user without all other users seeing the message.
The Server Program Code
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
[Code] ....
Now I have tried thing like having various input output streams and trying to connect those, but no luck. Tried fiddling with having the names arraylist directing the messages to one client versus all but that did not work out either. How I what I would need to do to go about doing this?
I am a first-timer using J2EE and here on coderanch.com and wanted to make a Simple Email-like System which a Registered User can Send Message/Email to another Registered User. how to do it. I have already my register/login process done but I'm stuck on how to make the Email. And I have an sample Bootstrap for my UserInterface which I want to use.
View Replies View RelatedI am trying to make a program that takes the information from the main args, and displays them as a email in another class when Java is run.
Ex.
From: PersonA
To: PersonB
Email message is here
I have gotten this far, but every time I append my "email.print()" into the next class, it never can print any of the Strings.
Main Args Class:
public class TestMessage {
public static void main(String[] args) {
Message email = new Message("Harry Morgan", "Rudolf Reindeer");
email.append("Dear so and so,");
email.append("It is my great pleasure to");
email.append("write you an email.");
email.append("");

I'm creating ftp program which server will send not existing files on client to him.
There is method responsible for creating connection and sending list of files on client written by me.
Java Code:
[JAVA]//client method
public void enableClient() throws IOException, ClassNotFoundException {
System.out.print("Rozpoczęto działanie klienta");
strIP = jtfIP.getText();
intPort = Integer.parseInt(jtfNrPortu.getText());
clientPath= "C:/serweris/";

I wrote a proxy in java. The version with ServerSocket-Socket/Stream-IO works wonderfully. When I rewrote it to ServerSocketChannel-SocketChannel/ByteBuffer it works also very well. However, when I access YouTube things happen weirdly: The video is frozen after 3 or 5 minutes (but this did not with the version of ServerSocket/Socket). I strongly assume that there probably was a nasty bug.... The (shortened) codes are:
Server:
public class BeanServer extends Thread {
public BeanServer( ) { }
public void run( ) {
try {
bServer = ServerSocketChannel.open();

I have an app that is randomly hanging it doesn't give any error information when it hangs.
Is there at way to see what's going on when it hangs? e.g. the methods that are being called, where is the program execution at..
We have a java application in our production enviroment using Spring framework which is configured with DBCP connection pool and the backend is Oracle database( version 11.2.0.3). Recently we encountered an occasionally happened situation(about once every week) and can be described as below:
The application schedules a task that runs every 10 minutes. And during task execution, the application would issue a SQL query of which the result is expected to be got within 10 seconds. At 11:51 a.m Oct 13th, however, the application failed to get the result within expected time, and 2 hours later, at 13:51, the result was finally returned to application. Due to lack of information at that time, we were not able to reproduce the same problem in test environment. At 15:31 p.m, Oct 29th, it happend again and this time we grasped all the information including thread dump and Oracle diagnostic information. We could found that:
1. Through oracle v$sql view, we could find that the SQL query is executed twice, at 15:31 and 17:31 respectively.
2. By analyzing TCP packets provided by network monitoring tools, it can be concluded that the request TCP packet containing SQL statement had been sent to Oracle and get executed, but after that JDBC only fetched first 80000 records out of 90000 records in total and then it stopped, didn't send any more request to Oracle to fetch rows. 2 hours later, Oracle sent a TCP keep alive packet and JDBC driver resume fetching remaining rows using the same connection(which can be confirmed by comparing source port of packets).
3. We dumped the thread at which JDBC hangs at socket read of JDBC driver
By the way, the version of JDBC we use is 11.2.0.1 and JDK version is 1.5.0_22.
The SQL statement is very simple:
select sum(n.netvalue) npvi,
n.HISCENEID hsid,
n.counterpartyid cid,
n.productid pid,
n.opendays

Tried every permutation and combination but all leading to this same error.
how to get the file size of an email attachment.
I used the following code to get this information.
l_EndUserObj.attachmentSize = mailAttachments.length();
The output is constant 2 even though the file size for each email attachment differ.
When I tried to use the getsize() I'm just getting an error that it is not a function.
I'm using BPM Studio during my coding.
I want to import a PDF file into a database, The PDF will be pulled from an email.
The PDF file must be imported into a specific user's profile.
When the user logs into his profile the file must be visible to that person only.

i am beginner in java. i was try to send email with MailAPI, follow is my code and error

Write a program that scans a text file for possible e-mail addresses. Addresses look like this:
someone@somewhere.net
Read tokens from the input file one by one using hasNext() and next(). With the default delimiters of Scanner, an entire e-mail address will be returned as one token. Examine each token using the indexOf() method of String. If a token contains an at sign @ followed some characters later by a period, regard it as a possible e-mail address and write it to the output file.
Programs such as this scan through web pages looking for e-mail addresses that become the targets of spam. Because of this, many web pages contain disguised e-mail addresses that can't easily be automatically extracted and above that is says to modify a program from our chapter which is this:
import java.util.Scanner;
import java.io.*;
class NamedFileInOut {
public static void main (String[] args) throws IOException {
int num, square;
[Code] ....
This is the first time hasnext() and next() have been introduced to me, so whereas scan.nextInt() looks for integers, does hasNext() looks for strings or characters? the wording in the exercise text is confusing to me. so basically i should create a text file with a ton of strings and within that jumble of text, stick a few email addresses; then when the program asks the user for the input file name, use that text file's name correct? pretty sure i have it up to that point, but using the indexOf() is what i'm having trouble wrapping my head around. do i look for the index of "@" and "."? i could conceptually see how i could say if the indexOf(".") is three spaces before the end then i know it's a .com or .net or .org or whatever. but how would i use indexOf("@") when the "user name" AND the "provider" (i.e. @yahoo or @google or @whatever) have an infinite number of lengths? we haven't had literally any discussion on input/output in classes so i am totally green to this.
how should i write appropriate methods to get user info like age, email address etc?
View Replies View Relatedi found a code to get emails from gmail in this forum.It's working very well, now i want to delete a specific sender email address.
So i can have the sender email with this:
Java Code: String senderAddress = aMessage.getFrom()[0].toString();
System.out.println(" From: " + senderAddress); mh_sh_highlight_all('java');
Now i want to do something like
Java Code: If (senderAddress = "test@gmail.com"){
message.setFlag(Flags.Flag.DELETED, true);
} mh_sh_highlight_all('java');
but it's not working.
I need to check the existence of email accounts before sending them mails to avoid going to a blacklist for sending to non real accounts.
I was thinking on (SSL)Sockets and smtp commands but I cant get it to work properly I am shooting in the dark here...
I have a JAVA application that sends mail to the people that buy certain things but the information quality is bad, so I must check if the mail exists before sending the mail....
I have saved emails that are stored in to text files and I want to retrieve the Sender, Reciever, Subject and the Email Content.I am using From: as a delimiter and To: as a delimiter and Subject as a delimiter and I am not sure what delimiter I should set for the email content.Also, there can be emails that will have comments after the message content and I plan on using the delimiter Comments:.
Any example of what delimiters I should use it would be great. Also I would like to know how check whether or not a delimiter exists so that I can print out the comments if it exists and if the file does not have comments, it prints out nothing.

I have a request to create a java scheduled job to send email with attachment of word document every week. any example codes I can use. This is my first time to code this request, I do not what is the standard way to do it.
View Replies View RelatedI will be developing a change and would like to know how can i parse a mail header in OBPM using java.
I want to get the message id, date and time the email recieved and email size.
Our code is already fetching the attachment of the email using the following syntax.
mailAttachments = mail.attachments;
I tried creating a variable like mailHeaders = mail.headers, would you know how can i get the details i want by parsing the variable? so far I wasn't able to check what mail.headers return as i'm currently having issues running our code locally due to DB connections.
I am reading mail by using pop3 in java mail. In outlook I found we can leave the copy of mail in server side after reading. Shall we do that process in java mail ?
