Message with attachment

In order to send message with file attachment you should encode your file to base64 encoding.
The following application demonstrate how to read a file located on your local disk, encode it to base64 and write the encoded file as a new file. For more information please consult our detailed documentation.
Note: the 3rd party package JavaMail is required.

  import java.io.*;
import javax.mail.internet.MimeUtility;
  public static void main(String[] args) {
  //initialize input and output file name
String strInputFileName = "enter file name (to encode) here";
String strOutputFileName = "enter output file name here";

rawFileToBase64(strInputFileName,strOutputFileName);
   
       }
  public static boolean rawFileToBase64 (String inFile, String outFile) {
  try {
  // initialize inputFile
FileInputStream fin = new FileInputStream(inFile);
BufferedInputStream bis = new FBufferedInputStream(fin);

// initialize outputFile
FileOutputStream fos = new FileOutputStream(outFile);
OutputStream os = MimeUtility.encode(fos,"base64");
BufferedOutputStream bos = new BufferedOutputStream(os);

byte data[] = new new byte[1024];
int len;

// read the buffered stream
while(bis.available()>0)
{
    len = bis.read(data);
    bos.write(data,0,len);
}

bos.close();
bis.close();
 
} catch (Exception e) {
  System.out.println("Unable to encode the contents of the request file."+ e);
}
