Hi,

I want to connect to gmail or Yahoo mail server to fetch the new messages. I am trying to connect to gmail using the code below, but I am getting this error:


" javax.mail.MessagingException: Connect failed;
nested exception is:
java.net.ConnectException: Connection timed out: connect
at com.sun.mail.pop3.POP3Store.protocolConnect(POP3St ore.java:161)"

What would be the reason? Can you please suggest ways to handle it?





public class TestMail{

public static void main(String[] args)
{
String user="xxx";
String passwd="yyy";
new TestMail().receive(user,passwd);
}


public void receive(String username,String password)

{
String host = "pop3.gmail.com";
try {
Properties prop = new Properties();
prop.setProperty("mail.pop3.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
prop.setProperty("mail.pop3.socketFactory.fallback", "false");
prop.setProperty("mail.pop3.port", "995");
prop.setProperty("mail.pop3.socketFactory.port", "995");

prop.put("mail.pop3.host", host);
prop.put("mail.store.protocol", "pop3");
Session session = Session.getDefaultInstance(prop);
Store store = session.getStore();
System.out.println("your ID is : "+ username);
System.out.println("Connecting...");
store.connect(host, username, password);
System.out.println("Connected...");
Folder inbox = store.getDefaultFolder().getFolder("INBOX");
inbox.open(Folder.READ_ONLY);

Message[] msg = inbox.getMessages();

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

for (int i = 0; i < msg.length; i++) {
System.out.println("Subject:" + msg[i].getSubject());
System.out.println("Read message? [Y to read / N to end]");
String line = reader.readLine();
if ("Y".equalsIgnoreCase(line))
{
handleMultipart(msg[i]);
System.out.println("****************************");
}
else if ("N".equalsIgnoreCase(line))
{
break;
}
else
{}
}
if (inbox != null) {
inbox.close(true);
}
if (store != null) {
store.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}

private void handle(Message msg) throws Exception {
System.out.println("From:" + msg.getFrom()[0].toString());
System.out.println("SentDate:" + msg.getSentDate());
}

private void handleText(Message msg) throws Exception {
handle(msg);
System.out.println("Content:"+msg.getContent());
}

private void handleMultipart(Message msg) throws Exception {
String disposition;
BodyPart part;
Multipart mp = (Multipart) msg.getContent();
int mpCount = mp.getCount();
for (int m = 0; m < mpCount; m++) {
handle(msg);
part = mp.getBodyPart(m);
disposition = part.getDisposition();
System.out.println(disposition);
if (disposition != null && disposition.equals(Part.ATTACHMENT))
{
BufferedReader areader = new BufferedReader(new InputStreamReader (System.in));
System.out.println("you get an attachment : " + part.getFileName());
System.out.println("Save attachment? [Y to read / N to end]");
String line = areader.readLine();
if ("Y".equalsIgnoreCase(line))
{
saveAttach(part);
}
else{}
} else if(disposition.equals(Part.INLINE)){
System.out.println(part.getContent());
} else {}
}
}

}



Thank you,

I can't get on either! So I guess we are not the only ones.

See Configuring other mail clients (http://mail.google.com/support/bin/answer.py?hl=en&answer=13287).

Blind stab: That document lists POP3 host as "pop.gmail.com" not "pop3.gmail.com" as in your code.

If speciy "pop3.gmail.com" as host

The error I get is
"java.net.UnknownHostException"

if speciy "pop3.gmail.com" as host...

Yes, the correct host is "pop.gmail.com". Your original post's code had "pop3.gmail.com".

Just change this line

Prop.put("mail.store.protocol", "pop3s");

I think the error is due to invalid username and password.
