Send Email from Java program using apache commons email

This api allows you to send email from your java progra. You can download the API from the folowing site
Download


Here I am giving you a sample code which lets you to send email fromyuor system

SimpleEmail email = new SimpleEmail();
email.setHostName("localhost");
try {
email.addTo("nimishth@gmail.com","Nimish T");
email.setFrom("admin@localhost");
email.setSubject("test");
email.setMsg("test message");
email.send();
} catch (EmailException e) {
e.printStackTrace();
}

first of all you have to include the downloaded library into u'r class path
after that write a java class and create an instarnce of SimpleEmail
then you have to set the set the host name, from address and to address
after that just add the message you want to send and and set a subject for the
perticular instance of the SimpleEmail class. here after you can call the sen method
which will send the email to the to address you have specified here its nimishth@gmail.com

If u want to send the mail using oter hservice providers such as gmail or oters
u have to change the the host name by the smtp address of the service provider you want to use
but there need authentication also
ie
SimpleEmail email = new SimpleEmail();
email.setHostName("smtp.gmail.com");
try {
email.addTo("nimishth@gmail.com","Nimish T");
email.setFrom("your email address");
email.setAuthentication("yoru email address", "your password");
email.setTLS(true);
//465 or 587 which is the port number here
email.setSmtpPort(587);
email.setSubject("Test");
email.setMsg("test");
email.send();
} catch (EmailException e) {
e.printStackTrace();
}

You will get more details about the mail such as attachment, html mail etc from
User Guide

Send Mail Using JAVA MAIL API

The JavaMail API is a set of abstract APIs that model a mail system. The API provides a platform independent and protocol independent framework to build Java technology based email client applications. The JavaMail API provides facilities for reading and sending email. Service providers implement particular protocols. Several service providers are included with the JavaMail API package; others are available separately. The JavaMail API is implemented as a Java optional package that can be used on JDK 1.4 and later on any operating system. The JavaMail API is also a required part of the Java Platform, Enterprise Edition (Java EE).
You can download Java Mail API from http://java.sun.com/products/javamail/downloads/

An Example program for sending mail using JAVA Mail
------------------------------------------------------------------
Before run the example code please goes through steps given below

1. download java mail API. and add to Classpath
2. Create one Gmail Account ( in this example we use google mail server as server)
3. edit the code "USERNAME = new gmail id" and PASSWORD = "password of new gmail id";
4. edit formAddress and to address.

/**
* CurrencyConverter provides an API for accessing the European Central Bank's
* (ECB) foreign exchange rates. The published ECB rates contain exchange rates
* for approx. 35 of the world's major currencies. They are updated daily at
* 14:15 CET. These rates use EUR as reference currency and are specified with a
* precision of 1/10000 of the currency unit (one hundredth cent). See:
*
* http://www.ecb.int/stats/exchange/eurofxref/html/index.en.html
*
* The convert() method performs currency conversions using either double values
* or 64-bit long integer values. Long values are preferred in order to avoid
* problems associated with floating point arithmetics. A local cache file is
* used for storing exchange rates to reduce network latency. The cache file is
* updated automatically when new exchange rates become available. It is
* created/updated the first time a call to convert() is made.
*
* @version 1.0 2008-16-02
