Re: SERVLET INTERNEL Error

Tariq.

This error occurs when javax.mail.Message.class is not found in the
classpath.

There is also a mismatch between the input parameters defined with the
method "send" and what you actually use when invoking the method (The
"request" object is not defined). This is not causing the exception, but
your class will probably not compile successfully.
