Document document = SAXReaderUtil.read(journalArticle.getContentByLocale(Locale.ENGLISH.toString()));
Node brandNode = document.selectSingleNode("/root/dynamic-element[@name='content']/dynamic-content");
String content = brandNode.getText();

InternetAddress fromAddress = null;
InternetAddress toAddress = null;

content = StringUtil.replace(content, new String[] { "[$firstName$]", "[$comment$]" },
new String[] { user.getFullName(),description });
try {
fromAddress = new InternetAddress("aaccc@gmail.com");
toAddress = new InternetAddress("bbccc@gmail.com");
MailMessage mailMessage = new MailMessage();
mailMessage.setTo(toAddress);
mailMessage.setFrom(fromAddress);
mailMessage.setSubject("Send mail by Using Tempelate");
