Sending an email thru javax.mail. facing some problem

hi
This is my code and when i run it i'm getting an error stating

Exception in thread "main" java.lang.NoClassDefFoundError: javax/activation/DataSource
        at MailTest.<init>(MailTest.java:31)
        at MailTest.main(MailTest.java:48)
I tried finding out other programs, but that doesn't give particualr exception.
i think the code is perfect
i didn't understand the "javax/activation/datasource"
 i need it very urgently.
i have attached my code also.


regards
Snehal
