There is a nice feature in the
SAP NetWeaver Application Server Java
, that can help you enhance your application but that for some reasons people are not aware of. Therefore, I have decided to write a blog about it and show you how you can add mailing functionality to your application.
The
SAP NetWeaver Application Server Java
provides a
JavamailClient service
, which ensures mail client features to the components running on the application server . As the J2EE specification requires , there is a
java:comp/env/mail/MailSession
object that is bound to the the application servre's naming envirnonment . This object can be looked up and used to send/check e-mails.
In your application, you need to lookup the java:comp/env/mail/MailSession object and get the appropriate “transport” or “store” protocol , using the Javamail API .

Here is a simple example how to send mail message in a JSP code:
</p>
<textarea name="JSP code" rows="45" cols="90" wrap="virtual">
<%@ page import="java.io.*,
javax.mail.*,
javax.naming.*,
javax.mail.internet.*" %>
<%
Transport tr = null;
try {
InitialContext ctx = new InitialContext();
Session ses = ( Session )ctx.lookup("java:comp/env/mail/MailSession");
tr = ses.getTransport( "smtp" );
// or ses.getTransport( "smtps" ); for SSL connection
tr.connect( "myHost.my", "user", "pass" );
MimeMessage message = new MimeMessage(ses);
message.setSubject("Test", "UTF-8");
message.setContent("This is test", "text/html;charset=UTF-8");
message.setRecipients(javax.mail.Message.RecipientType.TO, "test1@myHost.my");
InternetAddress[] to = new InternetAddress[]{new InternetAddress("bobby@myHost.my")};
message.addFrom(to);
tr.sendMessage( message, message.getAllRecipients() );
out.println("h1. Successfully sent!
");
} catch (Exception ex) {
out.println("<br><pre> Error:");
StringWriter strWr = new StringWriter();
ex.printStackTrace(new PrintWriter(strWr));
out.println(strWr.toString()+"</pre>");
} finally {
if (tr != null) {
tr.close();
}
}
%>
</textarea>
