Content-Transfer-Encoding: 7bit
Content-Disposition: attachment;
     filename="InterScan_Disclaimer.txt"
I am not setting the content type.
The content type is assumed by the mail server.
The code which i use is as follows::
public SendMail(Connection con,String incNo, String createdBy, String app, String priority,int upNo,String title,int flag)
String[] recipient_name = new String[10];
String[] recipient_mail_id = new String[10];
String sender_name = null;
String sender_id=null;
String msgText;
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd,yyyy");
Calendar today = Calendar.getInstance();
String dt = sdf.format(today.getTime());
String dtinc=null;
System.out.println(createdBy+"creator");
try
Statement stmt = con.createStatement();
ResultSet rs1 = stmt.executeQuery(" select user_first_name + ' ' + user_last_name as user_name, e_mail as mail_id from Users where e_mail NOT IN ('','null') AND e_mail IS NOT NULL AND mailing_flag = 1 ");
int i=0;
while (rs1.next())
recipient_name[i] = rs1.getString("user_name");
recipient_mail_id[i] = rs1.getString("mail_id");
i++;
stmt = con.createStatement();
ResultSet rs2 = stmt.executeQuery(" select user_first_name + ' ' + user_last_name as user_name,e_mail as mail_id from Users " +
               " where user_id = '" + createdBy + "'");
rs2.next();
sender_name = rs2.getString("user_name");
sender_id = rs2.getString("mail_id");
System.out.println(createdBy+sender_name);
System.out.println(createdBy+sender_id);
catch (Exception ex)
System.out.println(ex);
msgText = "A new update has been created for " + app;
msgText = msgText + "\nIncident # : " + incNo;
msgText = msgText + "\nUpdate # : " + upNo;
msgText = msgText + "\nTitle : " + title;
msgText = msgText + "\nCreated on : " + dt;
msgText = msgText + "\nCreated by : " + sender_name;
msgText = msgText + "\nPriority : " + priority;
String from = sender_name;
String host = "mail server IP";
boolean debug = Boolean.valueOf("true").booleanValue();
Properties props = new Properties();
props.put("mail.smtp.host", host);
if (debug) props.put("mail.debug", "true");
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
try
Message msg = new MimeMessage(session);
if(sender_id ==null || sender_id.equals("null")||sender_id.equals(""))
     sender_id="Default";

msg.addRecipient(Message.RecipientType.CC, ccAddress);
msg.setSubject("Update Notification for Incident #: " + incNo);
msg.setSentDate(new java.util.Date());
msg.setContent(msgText, "text/html");
Transport.send(msg);
catch (UnsupportedEncodingException ex)
System.out.println("\n--UnsupportedEncodingException in msgsendsample.java");
catch (MessagingException mex)
System.out.println("\n--Exception handling in msgsendsample.java");
mex.printStackTrace();
System.out.println();
Exception ex = mex;
do {
if (ex instanceof SendFailedException) {
SendFailedException sfex = (SendFailedException)ex;
Address[] invalid = sfex.getInvalidAddresses();
if (invalid != null) {
     System.out.println(" ** Invalid Addresses");

Answer 1

Good to see some other person also waiting for a reply!!
Well i know that the problem may arise when the message.settext() is used instead of message.setcontent()...
Also i have this problem rectified now and the change we did was
---some of the mail ids had capital letters in it.we changed all the letters to small letters
---change the settext to setcontent
I dont know whether these are the correct solutions
but may be this could help in getting the correct solution!!!!!!!
