saving a email as a .eml

[jordan ryan]

Ok i can read an e-mail as attached below but i now need to be able to save this email as a .eml so i can view it when i click on the saved location.
I assumed a file writer then changing the println to Append would work but it didn't seem to work. is there any easy way around this.

import java.io.FileWriter;
import java.io.InputStream;
import java.util.Properties;

import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Store;

public class ReadMail { 

  public static void main(String args[]) throws Exception { 

  String host = "host address";
  String user = "account name";
  String password = "password"; 
   Properties properties = System.getProperties(); 
  Session session = Session.getDefaultInstance(properties);
  Store store = session.getStore("pop3");
  store.connect(host, user, password);
  Folder folder = store.getFolder("inbox");
  folder.open(Folder.READ_ONLY);

  Message[] message = folder.getMessages();
	FileWriter writer = new FileWriter ("test.eml");
  for (int i = 0; i < 1; i++) {

  System.out.println("------------ Message " + (i + 1) + " ------------");

  System.out.println(message[i].getSentDate());
  System.out.println(message[i].getFrom()[0]);
  System.out.println(message[i].getSubject());

  InputStream stream = message[i].getInputStream();
  while (stream.available() != 0) {
  System.out.print((char) stream.read());
  }
  System.out.println();
  }

  folder.close(true);
  store.close();
	  	
	  	}
	}

First of all, available() doesn't do what you think it does.

Second, all you need to do is write the message to a file. Using Java 7's try-with-resources:

System.out.println(message[i].getSubject());

try (OutputStream out = new FileOutputStream("something.eml")) { // fix the name of course
    message.writeTo(out);
}
