Receiving Email With Attachment In Java

Receiving email with attachment in Java

As we receive the email, we can receive the attachment also by using Multipart and BodyPart classes found in JavaMail API.

For better understanding of this example, learn the steps of sending email using JavaMail API first.

For receiving or sending the email using JavaMail API, you need to load the two jar files:

• mail.jar
• activation.jar
