In this article, we want to discuss the way to Send email in Java through Gmail Server. We can send emails by using the SMTP server of Gmail. It is good if you are don’t have an SMTP server and reliable. Here we will learn how to send email through the Gmail server by SSL (Secure Sockets Layer). SSL is basically used for security if you are sending emails through a Gmail server.
For a better understanding of this example, learn the steps of sending an email using JavaMail API first. For sending the email using JavaMail API, you need to load the two jar files:
- mail.jar
- activation.jar
download these jar files (or) go to the Oracle site to download the latest version.
