public class MailMessage There are two general approaches to doing this. Here is the first one:
 
 MailMessage message = new MailMessage();
 message.setFrom("me@my.address");
 message.addRecipients("friend1@his.address, friend2@her.address");
 message.setSubject("Greetings");
 message.setBody("Hello everyone!");
 message.send();
 
Here is the second approach:
 
 MailMessage message = new MailMessage();
 message.parse("From: me@my.address\n"
             + "To: friend1@his.address, friend2@her.address\n"
             + "Subject: Greetings\n"
             + "Hello everyone!\n");
 message.send();
 
 You may mix and match the two approaches as desired. For example, you could use the parse method, then the addRecipient method. 
 Note: You must add your mail subsystem information to your server.properties file. An example follows: 
  #======================================================= 
 # Mail subsystem
 #=======================================================
 # Comma-delimited list of all smtp servers capable of
 # relaying mail to the internet
 mail.system.mail.smtp.host: mail
 # What port is the MTA listening on
 mail.system.mail.smtp.port: 25
 # Number of milliseconds to socket connet timeout. When
 # this limit is reached, we try the next mail server.
 mail.system.mail.smtp.connectiontimeout: 2000
 # Base mail template directory
 mail.templateRoot: $webRoot/config/mailTemplates
 # What email account to use when the system sends out
 # mails
