What is "html format mail" ?

Do you want the body of your mail to be of html type ? Have a look at the java mail API and the SMTP protocol.

Here is a tutorial

Thankyou John Meyers,
I have looked into the JavaMail tutorial and I am not convinced with the output. I'm still getting errors while sending. I want the code for sending the mail. For that i've used this code and it is working in my localhost system, but when i uploaded to the remote server, it is not working. Can you please tell me the reason?

Here is the code

    
 
String from = "[e-mail]";
String to = "[e-mail],[e-mail]";
 try
 {
     //SmtpClient client = new SmtpClient(smtp);
     SmtpClient client = new SmtpClient("mail.softnotions.com");
     client.from(from);
     client.to(to);
     //client.cc(cc);
     PrintStream message = client.startMessage();
     message.println("From: " + from);
     message.println("To: " + to);
     message.println("Subject:  New User Joined in Order Management System");
     message.println("Order Management Program");
     message.println("Dear Administrator,");
     message.println("");
     message.println("A new User/Client has signed-up in the Order Management Program. Please give the necessary rights to him.");     
     message.println("");
     message.println("Username:"+username);
     message.println("Firstname:"+fname);
     message.println("Lastname:"+lname);
     message.println("Office:"+office);
 message.println("");     
     message.println("Thanks and Regards");     
     message.println("Order Management Server");     
     client.closeServer();
  }
    catch (IOException e)
    {System.out.println("ERROR SENDING EMAIL:"+e);
    }
     response.sendRedirect("index.htm");

If it is working when run on your local system but not on a server, the problem could be security at the mail server. Typically mail servers only accept outgoing mail from certain senders and your JSP server is not cleared to send mail through the system you are trying to use.

Thanks for the reply.
Now i'm trying to run a simple java mail application from JavaMail API tutuorial and it is showing me errors

The code is here

 
<%@  page language="java"  import="javax.mail.*" import="javax.activation.*" import="java.util.*" import ="javax.mail.internet.*" import ="javax.mail.util.*" %>
<%
String host = "mail.softnotions.com";
String from = "[e-mail]";
String to = "[e-mail]";
 
// Get system properties
Properties props = System.getProperties();
 
// Setup mail server
props.put("mail.smtp.host", host);
 
// Get session
Session session = Session.getDefaultInstance(props, null);
 
// Define message
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject("Hello JavaMail");
message.setText("Welcome to JavaMail");

// Send message
Transport.send(message);
%>
 

and the error i'm getting is here

You cant use "session" when its already an implicit object.

MimeMessage(HttpSession) does not exist. MimeMessage(Session) does

[Bear Bibeault]

This has not a thing to do with JSP. Moved to Other Java APIs.

[Rashid Mayes]

When sending an message with html use the set content method of the MimeMessage class. i.e mimeMessage.setContent(htmlString,"text/html");

You may want to check the implementation of transport.send and smtptransport. I think it blocks until the first server in the delivery chain accepts the message for each recipient (cant remember exactly). If this is the case, sending the mail asynchronously will provide a better user experience especially in cases where a MX record points to a dead or slow server.
