Problem with reading the contents, from and to adresses while using javamail pop3

Nikhil

Hey,
I'm downloading mail from a google account using pop3.
The dowloading is going well(at least for some messages).
When I display the contents of the message or the sender and receiver
addresses it shows some wierd thing that at least I cannot
understand....

Following is my program:


import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import com.sun.mail.pop3.POP3Message;


public class PopTest2
{

private static final String SMTP_HOST_NAME = "smtp.gmail.com";
private static final String SMTP_PORT = "465";
private static final String emailMsgTxt = "Test Message
Contents";
private static final String emailSubjectTxt = "A test from
gmail";
private static final String emailFromAddress =
"(e-mail address removed)";
private static final String SSL_FACTORY =
"javax.net.ssl.SSLSocketFactory";
//private static final String[] sendTo = { "(e-mail address removed)"};


public static void main(String argv[])
{
AccountAuthentication auth = new AccountAuthentication();

String host = "pop.gmail.com";
String user = "myemailid";
String password = "mypassword";
String port = "995";

Properties props = new Properties();

//props.put("mail.debug", "true");
props.put("mail.pop3.host", host);
props.put("mail.pop3.user", user);
props.put("mail.pop3.port", port);
props.put("mail.pop3.starttls.enable","true");
props.put("mail.pop3.auth", "true");

props.put("mail.pop3.socketFactory.port", port);
props.put("mail.pop3.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("mail.pop3.socketFactory.fallback", "false");

Session session = Session.getDefaultInstance(props, auth);

try
{
Store store = session.getStore("pop3");

try
{
store.connect(host, user, password);

}
catch (MessagingException ex)
{
ex.printStackTrace();
}

try
{
if(store.isConnected())
{

Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);

Message[] msg = folder.getMessages();
//Calendar c = new Calendar();

int len = folder.getMessageCount();
Date d=new Date();
Date msgDate;

System.out.println("Message Count: " + len);
Part p;

for(int i = 0; i < len; i++)
{
Flags msgFlags = msg.getFlags();
//msgDate=msg.getReceivedDate();
Flags.Flag[] sf = msgFlags.getSystemFlags();
{
p=msg;
String subject = msg.getSubject();
System.out.println("\nSEEN message");
System.out.println("\nSubject[" + i +
"]:---------------> " + subject);
System.out.println("\nFrom-------------------
"+msg.getFrom());

System.out.println("\nTo--------------------->"+
(msg.getRecipients(Message.RecipientType.TO)).toString());
//System.out.println("From soft------------->" +
"(e-mail address removed)");
System.out.println("Content:----------------->
\n"+msg.getContent());
}

}
}
else
{
System.out.println("Unable to open the Inbox.");
}

}
catch (MessagingException ex)
{
ex.printStackTrace();
}
catch(IOException ex)
{
ex.printStackTrace();
}


}
catch (NoSuchProviderException ex)
{
ex.printStackTrace();
}
}
}


And following is the output :(of only one of the many mails of the
account)

SEEN message

Subject[9]:---------------> Re: Student project

From------------------->[Ljavax.mail.internet.InternetAddress;@13582d

To--------------------->[Ljavax.mail.internet.InternetAddress;@21b6d
Content:----------------->
[email protected]


Now I can assure you that the message does not contain
"[email protected]".

How do I get the mail ids of sender and receiver and the content?
Thanx for having a look....

Your post would be much easier to follow if you did not embed TAB characters
in it.

....
Message[] msg = folder.getMessages(); ....
System.out.println("\nFrom-------------------> "+msg.getFrom()); ....
And following is the output :(of only one of the many mails of the
account) ,,,
From------------------->[Ljavax.mail.internet.InternetAddress;@13582d


Well, of course we don't have the definition of Message in front of us, since
you didn't post an SSCCE, but dollars to doughnuts getFrom() doesn't return a
String. In fact, I will bet good money it returns a
javax.mail.internet.InternetAddress.

What is the type of Message.getFrom()?
(Hint: javax.mail.internet.InternetAddress)

What is the default output from toString() if one doesn't override it?

Thanks for replying....

Actually the getFrom method returns an array of type
javax.mail.internet.InternetAddress .
So now when i wrote the following statement, it printed the correct
address.

(msg.getRecipients(Message.RecipientType.TO))[0].toString()


But still I am not able to read the contents of the Messages whose
content type is MimeMultipart.
So how do I read contents of these messages?

You should be able to figure that out from the API documentation. Note
that different MessageParts may have different representations of the
actual message. One part may be text/html (or application/html), another
may be text/plain. It's all spelled out in the headers and the class
hierarchy. Note also that text may be encoded in, e g, Quoted Printable
or Base64. The header fields may also be encoded, if they contain
non-ascii characters.

Look at the example code in the JavaMail API Design Specification. While
you're at it, download the API documentation as well: the
Message.getFrom() method returns javax.mail.Address objects, which are
not the same as javax.mail.internet.InternetAddress object, which you'd
know if you'd looked at the API documentation.
