Junk characters display while using multipart with html content in Javamail

Question

Hi All,
I have used Java mail API to send mail with attachment. To enable to attachment in mail and to do content formatting i have used multipart and html content type together.
My web application runs on apache tomcat 5.5 in MAC server. Java version is 1.5.
The Function which i have used for sending mail with attachment is as follows:
public void sendmailAttached(String to,String from,String host,boolean debug,String mailContent,String mailSubject,String cc,String attachFiles)
          String mailarray[]=to.split(";");
          Properties props = new Properties();
          //props.put("mail.smtp.port","425");
          props.setProperty("mail.smtp.host", host);
          if (debug) props.setProperty("mail.debug", ""+debug);
          Session session = Session.getInstance(props, null);
          session.setDebug(debug);
          try {
               Message msg = new MimeMessage(session);
              msg.setFrom(new InternetAddress(from));
             javax.mail.internet.InternetAddress[] toAddress=new javax.mail.internet.InternetAddress[mailarray.length];
             for (int i=0;i<mailarray.length ;i++ )
                                        toAddress=new javax.mail.internet.InternetAddress(mailarray[i]);
          msg.setRecipients(Message.RecipientType.TO, toAddress);
          msg.setSubject(mailSubject);
          try{
                    String ccaray =cc;                    
                    String mailarray1[]=ccaray.split(";");
                    javax.mail.internet.InternetAddress[] CCAddress=new javax.mail.internet.InternetAddress[mailarray1.length];
     for (int i=0;i<mailarray1.length ;i++ )
     CCAddress[i]=new javax.mail.internet.InternetAddress(mailarray1[i]);
          msg.setRecipients(Message.RecipientType.CC,CCAddress);
          }catch(Exception ss)
                    System.out.println("CC mail exception is ====>"+ ss.getMessage());     
          msg.setSentDate(new java.util.Date());
          Multipart multipart = new MimeMultipart("related");
          BodyPart messageBodyPart = new MimeBodyPart();
          messageBodyPart.setContent(mailContent, "text/html");
          multipart.addBodyPart(messageBodyPart);
               String fileName = attachFiles.substring(attachFiles.lastIndexOf("/")+1,attachFiles.length());
               if(!fileName.equals(""))
                    messageBodyPart = new MimeBodyPart();
          DataSource source = new FileDataSource(attachFiles);
          messageBodyPart.setDataHandler(new DataHandler(source));
          messageBodyPart.setFileName(fileName);
          multipart.addBodyPart(messageBodyPart);
          msg.setContent(multipart);
          Transport.send( msg );
          catch(MessagingException mex)
               Exception ex = mex;
               if (ex instanceof SendFailedException)
               SendFailedException sfex = (SendFailedException)ex;
Address[] invalid = sfex.getInvalidAddresses();
if (invalid != null) {
if (invalid != null) {
for (int i = 0; i < invalid.length; i++)
System.out.println("Invalid Addresss --------> " + invalid[i]);
try
     Message msg = new MimeMessage(session);
          msg.setFrom(new InternetAddress(from));
          Multipart multipart = new MimeMultipart("related");
     BodyPart messageBodyPart = new MimeBodyPart();      
     messageBodyPart.setContent(mailContent, "text/html");
multipart.addBodyPart(messageBodyPart);
Address[] validUnsent = sfex.getValidUnsentAddresses();
javax.mail.internet.InternetAddress[] toAddress=new javax.mail.internet.InternetAddress[validUnsent.length];                         
if (validUnsent != null) {
for (int i = 0; i < validUnsent.length; i++)
System.out.println("Valid Address ------>"+validUnsent[i]);
String test = validUnsent[i]+"";
toAddress[i]=new javax.mail.internet.InternetAddress(test);
msg.setRecipients(Message.RecipientType.TO, toAddress);
msg.setSubject(mailSubject);
String fileName = attachFiles.substring(attachFiles.lastIndexOf("/")+1,attachFiles.length());
               if(!fileName.equals(""))
                    messageBodyPart = new MimeBodyPart();
          DataSource source = new FileDataSource(attachFiles);
          messageBodyPart.setDataHandler(new DataHandler(source));
          messageBodyPart.setFileName(fileName);
          multipart.addBodyPart(messageBodyPart);
msg.setContent(multipart);
Transport.send( msg );
catch(Exception e)
     System.out.println("Mail Not Send");
          else
                    System.out.println("Mail Server Not Connectd ");
This code is working properly and i am able to send mail with attachment and html formatted content without any problem. But console of server is filled up with too much junk characters because of which the catalina.out file of tomcat server is becoming fully filled.
Sample cosnole display with  junk characters are as follows:

Answer 1

There is no "sendmail" method in the JavaMail API.
The debug flag is set using the Session.setDebug method, or by setting the Session property "mail.debug".
If you're using someone else's helper classes with JavaMail, they may provide another way to set it.
