Hi, I created an online shopping website that sends confirmation email to customers once they finish shopping. I used javamail for sending email to the customers. It is functioning perfectly well on my "javawebserver" testing platform. But i am unable to do the same when i try to implement it on my company's "Novell netware" server. It is displaying the following exception: "500 java.lang.NoClassDefFoundError: javax/mail/Session java.lang.Exception: javax/mail/Session" i did copy the mail.jar to the server's servlet engine lib directory and set the classpath of the env. But it is still giving me the same problem again and again. Please help me how i could solve this problem.
