Java EE (Java Enterprise Edition) General Discussion

Hi All,

I am trying to connect to a mail server which is configured for POP3 access using SSL/TLS and cleartext login.

I have tried using the following code:

    
   public void connect() {
        try {
            Properties props = System.getProperties();

            Session session = Session.getDefaultInstance(props, new MailAuthenticator());
            store = session.getStore("pop3s");
                
            store.connect(popServer, popPort, popUser, popPassword);

            folder = store.getDefaultFolder();
            if (folder == null) {
                throw new Exception("No default folder");
            }

            folder = folder.getFolder("INBOX");

            if (folder == null) {
                throw new Exception("No POP3 INBOX");
            }

            folder.open(Folder.READ_ONLY);

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
    
    private class MailAuthenticator extends Authenticator{
        MailAuthenticator(){
            super();
        }
    }

But this just brings back the error:

javax.mail.MessagingException: Connect failed;
nested exception is: javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at
com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:148) at
javax.mail.Service.connect(Service.java:275) at
EMail.Pop3Retreiver.connect(Pop3Retreiver.java:128)

I have installed a certificate using the java keytool and the certificate is visible when you go to control panel and java|security.

Any ideas what i'm missing here as i have read the SSLNotes.txt and can't seem to get any further on this.

Help is appreciated.

Regards
