Hello! The JavaMail API defines the property 'from' based on the value of the fields 'Default User' and 'Default Return Address', which are located in the section JavaMail Sessions of the Glassfish console. You should define the fields with the email address that you want to be the 'from'.

This work excellent, except for a little detail. The mail arrived without a FROM. TO, SUBJECT and TEXT get well, but not the FROM. Default from address is already set in GF javamail session.
Which is the cause?

Thankx a lot

The one provided by the company or my own internet service provider. Maybe Google has some security constraints.

That is the problem, it does not return any error at all. If I specify the port to 465, then it just hang (like your cursor keep spinning), if I dont specify the port, then it does not hang but it does not send mail either. In both cases, no error return to the server log. What hosts do you usually use?

I use several hosts, but I never tried smtp.gmail.com. What is the error message produced by Glassfish? Usually the email server returns a description of the problem. In most of cases, it has nothing to do with the application server.

What Mail host and port do you use? I use smtp.gmail.com with port 465, but it hang. Email never send out, does glassfish 3.1 b25 not work well with smtp.gmail.com?

The main imports are:

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import javax.annotation.Resource;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.ejb.LocalBean;

import javax.mail.Message.RecipientType;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

The parameter "UserAccount" is a simple POJO to represent the user's entity.

hi,
It would be great to specify imports because some of them are a little ambiguous, but great article anyway...

"smtp.bla" doesn't seem to be a valid SMTP server. You need an email service provider, which could be your Internet provider, GMail, Yahoo and many others. They will give you instructions about a smtp address that you have access to, something like "smtp.google.com" or "smtp.aol.com", but you need username and password to access the server. Unless your email service is running in your own machine, which is rare, you should not use localhost too.

I have my resource set up with Mail Host: smtp.bla. However, I am getting a connection failure with the host: localhost. How do I get this to use the resource mail host. I have even tried to add a mail.smtp.host property

That's right. I forgot to mention this small detail. Just mentioning "EJB Session Bean" is not enough.

2010-10-14T13:45:58.650+02:00

i think the class UserAccountBsn has to be a container managed class to make the source from above runnable... In other classes, eg a very simple POJO without any further annotations, @Resource will only inject "null".

Very nice article. I found it extremely useful.
