Answer: You need two jars:

• mail.jar
• activation.jar

If you added both jar in your project please check your version. For maven project below dependency gives exception:

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4</version>
</dependency>

Then change it to 1.4.3 version as below:

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.3</version>
</dependency>

If you are using eclipse change mail.jar to latest version. java.lang.ClassNotFoundException-javax.mail.MessagingException should be fixed.
