Either your mail.jar file is corrupted, or possibly you have two versions of the
javax.mail.* classes in your class path.

Thanks for your response...

I am using eclipse IDE, in that i have build the path for the mail program with mail.jar and activation.jar , but i could not resolve the problem........

Hi!

Do you use some plugins with eclipse IDE, like Tomcat by example or other plugins ... ?
If yes, update mail.jar and activation.jar inside Tomcat or in your lib project Eclipse...

You have a conflict with the class loader that check for security for class javax/mail/MessagingException

See you Manifest.mf inside mail.jar :
(old version here...)

Manifest-Version: 1.0
Implementation-Version: 1.4
Specification-Title: JavaMail(TM) API Design Specification
Specification-Version: 1.3

Do you have j2ee.jar or javaee.jar in your CLASSPATH or in your Eclipse project
along with mail.jar? What other jar files do you have in your project?
