How to send email using gmail smtp

User_AYF65 · May 12, 2016 5:16AM

Hi,

I want to send email using gmail smtp. I downloded a program from internet but its producing lots of errors. The code is given below along with errors:

import javax.mail.*;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import java.util.Properties;

/**

*/

public class EmailExample {

public static void main(String args[]) {

final String username = "[email protected]";

final String password = "yourpassword";

Properties props = new Properties();

props.put("mail.smtp.auth", "true");

props.put("mail.smtp.starttls.enable", "true");

props.put("mail.smtp.host", "smtp.gmail.com");

props.put("mail.smtp.port", "587");

Session session = Session.getInstance(props,

new javax.mail.Authenticator() {

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(username, password);

}

});

try {

Message message = new MimeMessage(session);

message.setFrom(new InternetAddress("[email protected]"));

message.setRecipients(Message.RecipientType.TO,

InternetAddress.parse("[email protected]"));

message.setSubject("Test JCG Example");

message.setText("Hi," +

"This is a Test mail for JCG Example!");

Transport.send(message);

System.out.println("Mail sent succesfully!");

} catch (MessagingException e) {

throw new RuntimeException(e);

}

I am getting following errors:

The problem is NOT the 'email program'.

The problem in this thread, as with your other thread, is that you are trying to use Java when you haven't learned HOW to use it.

I suggest you STOP trying to write code before you know the language and how it works.

The Java Tutorials has trails on how to use ALL of the basic functionality.

https://docs.oracle.com/javase/tutorial/deployment/jar/downman.html

Adding Classes to the JAR File's Classpath

You may need to reference classes in other JAR files from within a JAR file.

If you want to reference a class in your code the class MUST BE on the classpath or the jar that contains the class must be in the classpath.

That is one of the FIRST THINGS you learn when you take any basic Java class.

You will continue to have problems if you don't learn the language BEFORE you try to write code.

There are NO SHORTCUTS.

I would suggest first write simple programs, and learn the basics of java, for example how to add the classpath etc..

One more thing don't just try to run the downloaded programs, without understanding what that does, and reading the readMe file (pre-requisite to run the program) to compile and execute it .

Have you added required jar files in project class path ?

Check this code-

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class SendMailSSL {
public static void main(String[] args) {
String to="[email protected]";//change accordingly
//Get the session object
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("[email protected]","password");//change accordingly
}
});
//compose message
try {
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));//change accordingly
message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
message.setSubject("Hello");
message.setText("Testing.......");
//send message
Transport.send(message);
System.out.println("message sent successfully");
} catch (MessagingException e) {throw new RuntimeException(e);}
}
}
