Is it possible to connect a java server, sending picture data with sockets, to an HTML page, that can then render those pictures on screen?
It would also be helpful to know how to send a response from the HTML page back to the java server. (If for example, someone clicked their mouse on the page)
import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
class SimpleMail1 {
public static void main(String[] args) throws Exception{
System.out.println("Sending mail...");
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.mymailserver.com");
props.setProperty("mail.user", "myuser");
props.setProperty("mail.password", "mypwd");
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(true);
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("HTML mail with images");
message.setFrom(new InternetAddress("me#sender.com"));
message.setContent
("<h1>This is a test</h1>"
+ "<img src=\"http://www.rgagnon.com/images/jht.gif\">",
"text/html");
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("you#receiver.com"));
transport.connect();
transport.sendMessage(message,
message.getRecipients(Message.RecipientType.TO));
transport.close();
}

I am trying to send mail using Java code . The code is working fine when running on my personal PC . But on office network the exception of unknown SMTP host is appearing. Also my office pc is not able to ping smtp.gmail.com. PC firewall is closed as well.
Is there any other way to establish the connection? I am also providing my code below for reference.
mport javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
import javax.mail.Authenticator;
public class otp {

d_uname="uname",//your email password

d_port = "587",
m_to = "target#gmail.com", // Target email address
m_subject = "Testing Mail programs",
m_text = "Hey, this is a test email.";

I guess that you are behind the internal firewall/proxy of your office, it is very common to put the whole internal network of a company behind a central firewall or to check Outgoing/Incoming requests of the networks traffic a Dynamic Proxy Server.in that case, you can check it in the proxy settings of your pc.
internet explorer(or any browser)-> settings -> internet option -> Connections Tab -> LAN Settings.
for the granular analyses,please attach your code.
you are using a gmail account but you have provided a outlook host , try the following template:

// Send message
Transport.send(message);
System.out.println("Sent message successfully....");
} catch (MessagingException e) {
throw new RuntimeException(e);
}enter code here
}
}
The following is my code.
This executed successfully. But I didn't see any mail in my inbox
Anybody please help.
import java.util.*;

System.out.println("Email sent");
}
catch (MessagingException e)

You'll need to either login and send over one of:
POP
IMAP
Gmail API
or you can use a domain you control, at the moment you are trying to send as gmail.com, and being ignored because it knows your IP is not allowed to send as gmail.com, because of SPF, which limits spam by setting who can send as which domains

i am creating a simple java mail program,the program is working ok and the last system print also working .but the problem is i dint received the mail in outlook.here i am using the company outlook.please some one help me.
i am attaching my code here
enter code here
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class SimpleSendEmail
{
public static void main(String[] args)
{
String host = "compny host";
String from = "mail id";
String to = "usr#some.com";
String subject = "birthday mail";
String messageText = "I am sending a message using the"
+ " simple.\n" + "happy birthday.";
boolean sessionDebug = false;
Properties props = System.getProperties();
props.put("compny host", host);
props.put("mail.smtp.port", "25");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.starttls.enable", "true");
Session session = Session.getDefaultInstance(props, null);
// Set debug on the Session so we can see what is going on
// Passing false will not echo debug info, and passing true
// will.
session.setDebug(sessionDebug);
try
{
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = { new InternetAddress(to) };
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(messageText);
Transport.send(msg);
System.out.println("Sent message successfully....");
}
catch (MessagingException mex)
{
mex.printStackTrace();
}
}
}
output
Sent message successfully....
"Compny host" doesn't seem like correct host. Check out this tutorial http://www.tutorialspoint.com/java/java_sending_email.htm and here you have also a few examples of sending emails in Java Send email using java
I do expect that you are using the correct host on your side.
But you are missing Username and Password.
transport = session.getTransport("smtp");
transport.connect(hostName, port, user, password);
transport.sendMessage(message, message.getAllRecipients());
or you can use the Authenticator:
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
I would like to send email without authentication using java.
Can someone help me?
With authentication, I do it as follows:
public void sendEmail() throws EmailException{
SimpleEmail email = new SimpleEmail();
email.setHostName("smtp.gmail.com");
email.setSmtpPort(465);
email.addTo("XXX#gmail.com", "XXXX");
email.setFrom("XXXX#gmail.com","XXXXX");
email.setSubject("testando . . .");
email.setMsg("testando 1");
email.setSSL(true);
email.setAuthentication("xxxxxx#gmail.com", "XXXXX");
email.send();
}
I forgot to say that i do not have a provider. i need an provider finally, i have emailFrom Subject and Message, and need send this email how?
If it is only for testing purposes, you may try Papercut. While it’s running, Papercut automatically picks up e-mail sent to the standard SMTP port (25) on any IP address. You just send mail from your application and switch to Papercut to review it.

Trying to get Play! Framework to send an email with an attachment. Code below works fine if I don't add the attachment to the message. I've tried both with Play's Mailer class and with the Apache Commons classes (as below), but in both cases, the page just sits there with a spinner (Chrome) and no email is received.
EmailAttachment attachment = new EmailAttachment();
attachment.setURL(new URL(base + "public/images/triangles.png"));
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription("test");
attachment.setName("test");
emailaddress = "test#test.com";
MultiPartEmail email = new MultiPartEmail();
email.setDebug(true);
email.addTo(emailaddress);
email.setFrom("Testing <test#test.com>");
email.setSubject("Testing email");
try
{
email.attach(attachment);
}
catch (EmailException ex)
{
System.out.println(ex.getMessage());
}
email.setMsg("test email");
email.send();
Im guessing you've already had a look at the Examples for Apache Commons and Sending e-mail - Play! Framework 1.1?
IMO I'd suggest using a well known library with loads of documentation and examples like JavaMail and their api.
Here are a few tutorials that will get you started immediately:
