NoClassDefFoundError
Hi,
I am trying to use the mail service of JBoss3.0.6
I have used the MailerBean example specified in the JBoss documentation.
But wierdly when I run the client for the Malier EJB, I am getting NoClassDefFoundError exception. (trace is attached below)
I have double-checked that activation.jar is present in server/default/lib and I also added it explicitly to the JBoss classpath.
I would greatly appreciate if anyone could let me know what I am doing wrong.
Thank you,
Sony
