Error in the implementation

Question

I wrote the followring method:
public void sendMail( )  {
    //@@begin sendMail()
       String host =" "; // Specify the host
     // Get the From Address
     String from = wdContext.currentContextElement().getFromAddress();
     // Get the To Address
     String to = wdContext.currentContextElement().getToAddress();
     // Initialize Session
     Properties props = System.getProperties();
     props.put("mail.smtp.host", host);
*     Session session = Session.getDefaultInstance(props, null);*
     // Create new MimeMessage
*     MimeMessage message = new MimeMessage(session);*
     try {
          // Set the From Address
*          message.setFrom(new InternetAddress(from));*
          // Set the To Address
          message.addRecipient(message.RecipientType.TO,
          new InternetAddress(to));
          // Set the Subject
          message.setSubject("Test Mail");
          // Set the Text
          message.setText(wdContext.currentContextElement().getTextMessage());
          // Send message
          Transport.send(message);
          messageMgr.reportSuccess("Mail Sent Successfully");
          } catch (AddressException e) {
          messageMgr.reportException(e.toString(),false);
          } catch (MessagingException e) {
          messageMgr.reportException(e.toString(),false);
    //@@end
The problem is that it complains on: Session, MimeMessage, InternetAddress, AddressException and MessagingException. Why is it doing that Should I have done something before?

Answer 1

As I said earlier, please add 3 jar files, viz., smtp.jar, activation.jar, mail.jar
Please use below mentioned code:
String strMailDetail[] = new String[10];
StringBuffer strMailBody;
try
strMailBody = new StringBuffer();
Properties props;
Session session;
Provider p;
String strSMTPIPAddress =  // Enter SMTP Server address here
java.util.Date todayDate = new java.util.Date();
// Get System Properties
props = System.getProperties();
// Setup SMTP Mail Server
props.put("mail.smtp.host", strSMTPIPAddress);
// Get session without Authenticator
session = Session.getDefaultInstance(props, null);
p = session.getProvider("smtp");
Message message = new MimeMessage(session);
message.setFrom("email_ID");
message.addRecipient(Message.RecipientType.TO, "email_ID");
message.addRecipient(Message.RecipientType.CC, "email_ID");
MimeBodyPart mbp = new MimeBodyPart();
mbp.setText(strMailBody.toString());
Multipart mt = new MimeMultipart();
message.setContent(mt);
message.setSentDate(new java.util.Date());
//Send message
Transport.send(message);
catch (Exception e)
wdComponentAPI.getMessageManager().reportException(e+" in Send Mail method", false);
