jdk is 6u35 and java mail is javamail-1.4.7.
code as:
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
public class SendEMail {
public static void main(String args[]){
// Common variables
String host = "******";
  String from = "******https://wpccas.usace.army.mil/owa/redir.aspx?C=5kX_FFemQUqZpuK0W1A77yJF-kfh6dAIY7WRJgxOIuOvfrUlxyCsuX1jIVlOmv7oDTKyZmFfrN0.&URL=mailto%3aP2%2fSys-Admin%40usace.army.mil";

props.put("mail.smtp.host", host);
  props.put("mail.debug", "true");

// Get session
  Session session = Session.getInstance(props);
  try {
  // Instantiate a message
  Message msg = new MimeMessage(session);
  // Set the FROM message
  msg.setFrom(new InternetAddress(from));
  // The recipients can be more than one so we use an array but you can
  // use 'new InternetAddress(to)' for only one address.
  InternetAddress[] address = {new InternetAddress(to)};
  msg.setRecipients(Message.RecipientType.TO, address);
  // Set the message subject and date we sent it.
  msg.setSubject("Email from JavaMail test");
  msg.setSentDate(new Date());
// Set message content
  msg.setText("This is the text for this simple demo using JavaMail.");
  // Send the message
  Transport.send(msg);
  catch (MessagingException mex) {
  mex.printStackTrace();
It was compiled successfully as

Could not find the main class: SendEMail. Program will exit.

Please advise.
Could it be the mail version not compatible with java 6u35?

Answer 1

You didn't include mail.jar in your CLASSPATH when you ran the program.
$ java -cp .:/tmp//javamail-1.4.7/mail.jar SendEMail
