Below I have my servlet using both the attribute and dispatcher methods, the setAttribute() param is an instance of my Employee class. On the jsp file I am getting no output on the page; also, I am not getting any exceptions. I have read on the naming conventions using getters for a Bean but I do not believe that this is the case in this instance? Any help would be appreciated.
