Is this code, part of a servlet/web application or is it a standalone java application?

knarenderreddy,

You don't have to post your comments in "bold". Your first post did not mention whether the lookup code was part of a standalone client or a web application and that was the reason why i asked you that question.

Are you packaging mail.jar as part of your web application, which might be resulting into classloader conflicts? See this http://wiki.jboss.org/wiki/ClassCastExceptions for possible ways to debug the exception. Specifically have a look at the jmx-console method mentioned over there.
