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

    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
    Implementation-Title: javax.mail

    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?
