I managed to send an email even inside forms with
public static void sendEmail(IPage source, IPage page, IRequestCycle
cycle, String from, String recipient, String subject) {
IForm cform = Form.get(cycle);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
HTMLWriter writer = new HTMLWriter(baos);
cycle.activate(page);
cycle.renderPage(writer);
writer.flush();
String semail = baos.toString();
semail = semail.replaceAll("img src=\"/", "img src=\"http://";
+ cycle.getRequestContext().getServerName() +
((cycle.getRequestContext().getServerPort() == 80)?"":(":"
+ cycle.getRequestContext().getServerPort())) + "/");
semail = semail.replaceAll("href=\"/", "href=\"http://";
+ cycle.getRequestContext().getServerName() +
((cycle.getRequestContext().getServerPort() == 80)?"":(":"
+ cycle.getRequestContext().getServerPort())) + "/");
Context initCtx;
try {
initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
Session session = (Session) envCtx.lookup("mail/Session");
MimeMultipart content = new MimeMultipart("alternative");
//MimeBodyPart text = new MimeBodyPart();
MimeBodyPart html = new MimeBodyPart();
//content.addBodyPart(text);
content.addBodyPart(html);
Message message = new MimeMessage(session);
html.setContent(semail,"text/html;charset=\"UTF-8\"");
message.setContent(content);
message.setFrom(new InternetAddress(from));
InternetAddress to[] = new InternetAddress[1];
to[0] = new InternetAddress(recipient);
message.setRecipients(Message.RecipientType.TO, to);
message.setSubject(subject);
message.setSentDate(new Date());
//message.setContent(content);
Transport.send(message);
s_logger.debug("Message sent from " + from + " to " + recipient
+ ":" + subject);
} catch (NamingException e) {
s_logger.debug(e);
} catch (AddressException e) {
s_logger.debug(e);
} catch (MessagingException e) {
s_logger.warn(e);
}
page.detach();
if (source != null) {
cycle.activate(source);
cycle.setAttribute(IForm.ATTRIBUTE_NAME,cform);
}
}
An official API to render pages anywhere inside a page for this
purpose would be really nice.
