how to send a mail with data extracted from a database with javamail and smtp?

Question

hi, i want to send emails to an address with a java program (using javamail) via smtp. it actually send the emails to the destination. the problem is the body of the email isn't send fully each time. considering that the body of my mail is extracted from a database. here's my code:

public static void Bmail(Connection conn, String grav, String state)
    {
        Statement stmt;

        try
        {
            stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);

            ResultSet res = stmt.executeQuery("select ID, Time_C from production where name='"+grav +"' and State='"+state+"'");

            while(res.next())
            {                           
                String id=res.getString("1"), tc=res.getString("2"); 
                    testmail smtpMailSend = new testmail();
                String sub="Alert "+grav+" "+state;
                    String mes=" ID "+id +"\n Stat: "+state +"\n time: "+tc;
                  smtpMailSend.sMail(sub,mes);
             }
         } catch(Exception e)
        {
            e.printStackTrace();
            stmt = null;
        }
    }
public void sMail(String obj,String text)throws MessagingException
{
Properties props = new Properties();
    props.put("mail.smtp.host", d_host);
    props.put("mail.smtp.port", d_port);
    props.put("mail.smtp.starttls.enable","true");
    props.put("mail.smtp.debug", "true");
    props.put("mail.smtp.auth", "true");
    Authenticator auth = new SMTPAuthenticator();
    Session session = Session.getInstance(props, auth);
    session.setDebug(true);
    Message msg = new MimeMessage(session);
    msg.setText(text);
    msg.setContent(text,"text/plain");
    msg.setSubject(obj);
    msg.setFrom(new InternetAddress(d_email));
    msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
    msg.saveChanges();
    Transport transport = session.getTransport("smtps");
    transport.connect(d_host, d_port, d_uname, d_password);
    transport.sendMessage(msg, msg.getAllRecipients());
    transport.close();
    }

so after 2 first record, i've in the mail "ID: 12345" without the time or the state.

well i tried setContent but i still have the same problem. maybe the content type is the cause (i'm putting text/plain)?

thanks for your help
