You are not running this in an application server? Apparently JavaMail is not on your (runtime) classpath. You can find it in maven here:
http://download.java.net/maven/2/javax/mail/mail/
You also need javax.activation, which for some reason you get from maven central:
http://repo1.maven.org/maven2/javax/activation/activation/1.1/
If you don't use maven, you can still get the jars from these urls.
