If you want to use the javamail, firstly, you must download the jaf from http://java.sun.com/beans/glasgow/jaf.html from this, you will get the activation.jar file.

after that you must download the javamail from http://java.sun.com/products/javamail to get the mail.jar file.

Let's copy two of the above file into the [%javaHome%]/jre/lib/ext directory. (or you can set classpath as normally if you want). That's all the job that you should have to do to import javax.mail.*

Hope that this will help you... good luck.
