Wildfly: Encrypt password for EJB remote java

I am trying to ecnrypt my password for EJB remote client. I tried encode64 or added it to config but nothing worked. I am not sure if it is possible. Any suggestions?
Here is my code:
Context context;
final clientProperties = new Properties();
clientProperties.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
clientProperties.put("remote.connection.default.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");
clientProperties.put(remote.connections", default);
clientProperties.put("remote.connection.default.host", "server_host");
clientProperties.put("remote.connection.default.port", "8080");
clientProperties.put("remote.connection.default.username", "ejb");
clientProperties.put("remote.connection.default.password", "password");
clientProperties.put(Context.INITIAL_CONTEXT_FACTORY, org.wildfly.naming.client.WildflyInitialContextFactory");
context = new InitialContext(clientProperties);

sending e-mails automatically

I'm trying to setup a program which can automatically send e-mails. However, the first step doesn't even work for me and it gives this error:
com.sun.mail.util.MailConnectException: Couldn't connect to host, port: 127.0.0.1, 25; timeout -1;

This is the code:
// File Name SendEmail.java
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class server {
public static void main(String [] args) {
// Recipient's email ID needs to be mentioned.
String to = "my other email properly written";
// Sender's email ID needs to be mentioned
String from = "my email properly written";
// Assuming you are sending email from localhost
String host = "127.0.0.1";
// Get system properties
Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", host);
// Get the default Session object.
Session session = Session.getDefaultInstance(properties);
try {
// Create a default MimeMessage object.
MimeMessage message = new MimeMessage(session);
// Set From: header field of the header.
message.setFrom(new InternetAddress(from));
// Set To: header field of the header.
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set Subject: header field
message.setSubject("This is the Subject Line!");
// Now set the actual message
message.setText("This is actual message");
// Send message
Transport.send(message);
System.out.println("Sent message successfully....");
} catch (MessagingException mex) {
mex.printStackTrace();
}
}
}
Does anyone have any idea why this happens and how to solve this? My e-mail is actually open etc. And because it's localhost I have no idea why it wouldn't work.

Access to a SMTP server would require the smtp host port and the security settings if applicable.
Properties props = new java.util.Properties();
props.put("mail.smtp.host", "hostname") #
props.put("mail.smtp.port", "portnumber") #25
props.put("mail.smtp.starttls.enable", "boolean value true or false")
props.put("mail.smtp.auth", "boolean value true or false")
Usually a session need to be created (a Java mail session using the username and password and the properties), that is missing in the code above. For demonstration purpose,
Session session = javax.mail.Session.getInstance( props,
new javax.mail.Authenticator() {
protected javax.mail.PasswordAuthentication getPasswordAuthentication() {
return new javax.mail.PasswordAuthentication("username", "password"); //username and password
}
});

JavaMail contact us swing form programming

I want to program a "Contact Us" form in my desktop application (Swing in Netbeans), just like what we find in some websites.
The problem that I faced is the smtp server name. Actually, I want that the user could send me a message without giving his address mail and without requiring that he connects to his account either.
Here a screen shot:
And this is my Submit button action:
#Override
public void actionPerformed(ActionEvent e) {
boolean isSent = true;
try {
//Properties properties = new Properties();
Properties properties = System.getProperties();
// properties.setProperty("mail.smtp.submitter", contactUs.getMailField().getText());
//properties.setProperty("mail.smtp.auth", "false");
properties.setProperty("mail.smtp.host", "localhost");
//properties.put("mail.smtp.user", txtfrom.getText());
//properties.put("mail.smtp.port", txtPort.getText());
//properties.put("mail.smtp.socketFactory.port", txtPort.getText());
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.put("mail.smtp.socketFactory.fallback", "false");
//Authenticator mailAuthenticator = new MailAuthenticator();
Session mailSession = Session.getDefaultInstance(properties);
Message message = new MimeMessage(mailSession);
InternetAddress fromAddress = new InternetAddress(contactUs.getMailField().getText());
InternetAddress toAddress = new InternetAddress("mancha#gmail.com");
message.setFrom(fromAddress);
message.setRecipient(Message.RecipientType.TO, toAddress);
message.setSubject(contactUs.getSubjectField().getText());
message.setText(contactUs.getMsgField().getText());
Transport.send(message);
} catch (Exception ex) {
contactUs.getErrorMsg().setText("ERROR:" + ex.getMessage());
isSent = false;
}
if (isSent == true) {
contactUs.getSubmitBtn().setEnabled(false);
contactUs.getErrorMsg().setText("Your e-mail has been sent.");
}
}
Of course I google and I found that simple example which causes always problem of connection to smtp server.

First of all, make sure that your smtp server listens on port 25.
you can check it via telnet.
telnet localhost 25
if you do not have any, install a smtp service to your system.
if you have, check your smtp services security settings to connect it

Firstly check that your mail server is up and running by running
telnet localhost 25
Secondly you don't want to set the fromAddress as the users 'prescribed' email as that would require the account exists on your local mail server (As often people contacting you wouldn't already be on your system). Instead, temporarily hard code the fromAddress to an email address you know exists on your mail server and just append the users email address to the email.
An example of what you might want to do
final String FROM_EMAIL_ADDRESS = yourexistingemail#mailserver.com;
InternetAddress fromAddress = new InternetAddress(FROM_EMAIL_ADDRESS);
message.setText(contactUs.getMsgField().getText(), "\nFrom: " + contactUs.getMailField().getText());

Logging into multiple gmail accounts to read messages in inbox in java using imaps

I'm beginner,
I'm writing a program which logins into my g-mail accounts and checks the messages in the Inbox.
To do this I'm using imaps ("imaps.gmail.com").
But what my problem is while logging into all the accounts, checking the messages in it one by one.
Program Reporting an error/kind of:
javax.mail.AuthenticationFailedException: [ALERT] Please log in via
your web browser: some url (Failure) imaps: xxxx#gmail.com for the
second and other accounts...
From this What I understand is I'm not closing sessions, store properly. So,Program is unable to check in the respective second and rest mail accounts..
Someone Help (With clarification)..
And the architecture of my code:
public class InboxRead {
public static boolean release = false;
private Session session = null;
public void checkInbox(String username, String password) {
// logging into account using imaps..
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
session = Session.getDefaultInstance(props, null);
store = session.getStore("imaps");
store.connect("imap.gmail.com", username, password);
System.out.println(store);
// reading inbox... closing all folders here
store.close();
session = null;
release = true;
}
public static void main(String[] args) {
for(;;) { // gives no of accounts with credentials..
do {
String username = "xxx#gmail.com";
String password = "xxxx";
InboxRead.checkInbox(username, password);
} while(release);
}
}
}
...

Its a Google gateway thrown error. Google maintain high security in the aspect of profile access or even mail access but even that can be controlled by the user using below link Google secure control
go to that link with your google account and select "turn on" and then try to execute your program.

Can't connect to Hotmail with JavaMail

First, let me appoligize if this is a duplicate question. Over the last couple of calendar months, I have been attempting to send email, using JavaMail; via my Hotmail account. I have used the numerious tips and code snipits that have been posted to this site in the past on this topic; however, I am still getting a java.net.ConnectException: Connection refused... when I execute the Transport.connect method
Here's my code
String fromUserName = "testEmailAddress#hotmail.com";
String fromEMailAddress = "My Email Test <testEmailAddress#hotmail.com>";
String fromEmailPassword = "testEmailPassword";
String emailServerName = "smtp.live.com";
String emailServerPort = "587";
String toEMailAddress = "<TestDestinationEmailAddress#gmail.com>";
Properties emailProps = System.getProperties();
emailProps.put("mail.smtps.host", emailServerName);
emailProps.put("mail.smtps.auth", "true");
emailProps.put("mail.transport.protocol", "smtps");
emailProps.put("mail.smtps.starttls.enable", "true");
emailProps.put("mail.smtps.ssl.enable","true");
emailProps.put("mail.smtps.port", emailServerPort);
emailProps.put("mail.debug", "true");
Authenticator localAuthenticator = new SMTPAuthenticator(fromUserName, fromEmailPassword);
Session emailSession = Session.getInstance(emailProps, localAuthenticator);
try {
SMTPTransport emTransport = (SMTPTransport) emailSession.getTransport("smtps");
emTransport.connect(emailServerName, Integer.parseInt(emailServerPort), fromUserName, fromEmailPassword);
System.out.println("Ok, we connected ok.");
MimeMessage emailMsg = new MimeMessage(emailSession);
emailMsg.addRecipient(Message.RecipientType.TO, new InternetAddress(toEMailAddress));
emailMsg.setFrom(new InternetAddress(fromEMailAddress));
emailMsg.setSubject("Automated Notification Number 1");
emailMsg.setContent(getHtmlContent(), "text/html");
emTransport.sendMessage(emailMsg, emailMsg.getAllRecipients());
System.out.println("Sent Message#: 1");
} catch (Exception e) {
e.printStackTrace();
}
And here's the exception...
DEBUG JavaMail version 1.4.5
DEBUG successfully loaded resource: /META-INF/javamail.default.providers
DEBUG SMTP useEhlo true, useAuth true

A couple of things:
I have tried both "smtp" and "smtps"...it doesn't seem to matter
I have tried ports: 25, 465, 587, and 995...still refuses the connection
I have tried the code on many computers with the same results.
Cut-and-pasted the code from the JavaMail demo code but stll get the error.
The code works for yahoo, at&t, gmail, and others...but not Hotmail!

I removed all the "socketFactory" stuff, as in Using javamail to send from hotmail?
Then it worked fine...
Below is the function:
private Properties _setProperties() {
Properties props = new Properties();
props.put("mail.smtp.host", _host);
if(_debuggable) {
props.put("mail.debug", "true");
}
if(_auth) {
props.put("mail.smtp.auth", "true");
}
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", _host);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.port", _port);
return props;
}

Presumably you've already read this JavaMail FAQ entry.
Did you also try the debugging tips here?
From the debug output you posted, it looks like you have a firewall or something that's preventing you from connecting to that site.
