Java Mail Code To Send EMAIL

E-Mailing Through Java Mail

* You use the JavaMail API where as JavaMail implementation providers implement the JavaMail API to give you a JavaMail client (Java JAR file). Sun gives you mail.jar which has Sun's SMTP, POP3 and IMAP client implementations along with the JavaMail API. This is sufficient to send and receive e-mail but not to read or post to newgroups which use NNTP.

Sample Code to Send E-Mail

* To compile and run, you must have mail.jar (from the JavaMail download) and activation.jar (from the JavaBeans Activation Framework download) in Java classpath.

* You need to replace email addresses and mail server with your values where noted. Username and password is generally not needed to send e-mail although your ISP may still require it to prevent spam from going through its systems.

import java.util.*;

import javax.mail.*;

import javax.mail.internet.*;

import javax.activation.*;

// Send a simple, single part, text/plain e-mail

public class TestEmail {

public static void main(String[] args) {

// SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!

String to = "vipan@vipan.com";

String from = "vipan@vipan.com";

// SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!

String host = "smtp.yourisp.net";

// Create properties, get Session

Properties props = new Properties();

// If using static Transport.send(),

// need to specify which host to send it to

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

// To see what is going on behind the scene

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

Session session = Session.getInstance(props);

try {

// Instantiatee a message

Message msg = new MimeMessage(session);

//Set message attributes

msg.setFrom(new InternetAddress(from));

InternetAddress[] address = {new InternetAddress(to)};

msg.setRecipients(Message.RecipientType.TO, address);

msg.setSubject("Test E-Mail through Java");

msg.setSentDate(new Date());

// Set message content

msg.setText("This is a test of sending a " +

"plain text e-mail through Java.\n" +

"Here is line 2.");

//Send the message

Transport.send(msg);

}

catch (MessagingException mex) {

// Prints all nested (chained) exceptions as well

mex.printStackTrace();

}

}

}//End of class

Sample Code to Send Multipart E-Mail, HTML E-Mail and File Attachments

* To compile and run, you must have mail.jar (from the JavaMail download) and activation.jar (from the JavaBeans Activation Framework download) in Java classpath.

* You need to replace email addresses and mail server with your values where noted.

* This sample code has debugging turned on ("mail.debug") to see what is going on behind the scenes in JavaMail code.

Downloading File in struts using DownloadAction, Struts Download File Action, Download Code for file download in struts.

 Implementing a DownloadAction
You need to extend org.apache.struts.actions.DownloadAction and implement the getStreamInfo() method. Optionally you can also override the getBufferSize() method if you require a different buffer size from the default.
Implement the getStreamInfo() Method
The getStreamInfo() method returns a StreamInfo object - which is an inner interface of the DownloadAction. The DownloadAction provides two concrete implementations (static inner classes) of the StreamInfo interface:
* FileStreamInfo - Simplifies downloading of a file from disk - need to pass a java.io.File object to the constructor along with the content type.
* ResourceStreamInfo - simplifies downloading of a web application resource - need to pass the ServletContext, path and content type to its constructor.
In the examples below referring by link, I have also provided a Byte array implementation of the StreamInfo interface. Implement the getBufferSize() Method.
The DownloadAction, by default, returns a buffer size of 4096. Optionally, this may be overriden to customize the size of the buffer used to transfer the file.
Link Shows here  below is having three examples:
* using a File
* using a web application resource
* using a byte array.
