How to read the message body in a mail

Question

how can we read the message body of a mail. i am using pop3 server for reading the mails. my program is
public class GetMessageExample {
public static void main (String args[]) throws Exception {
String host = args[0];
String username = args[1];
String password = args[2];
Properties props = new Properties();
Session session = Session.getInstance(props, null);
Store store = session.getStore("pop3");
store.connect(host, username, password);
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
BufferedReader reader = new BufferedReader (
new InputStreamReader(System.in));
Message message[] = folder.getMessages();
for (int i=0, n=message.length; i<n; i++) {
System.out.println(i + ": " + message.getFrom()[0]
+ "\t" + message[i].getSubject());
System.out.println(
"Do you want to read message? [YES to read/QUIT to end]");
String line = reader.readLine();
if ("YES".equals(line)) {
message[i].writeTo(System.out);
} else if ("QUIT".equals(line)) {
break;
folder.close(false);
store.close();
i am getting the following exception
Exception in thread "main" java.lang.NoSuchFieldError: contentStream

Answer 1

The Part interface that the Message class implements describes 3 ways for getting the content of a message. To use an Input Stream, you can call the getInputStream() method on the message itself, rather than System.in.
Hope this helps!
