JSP's get converted to servlets before execution, so when your using JSP's you're using servlets. Many people, myself included, use servlets for the business logic and use JSP's for the presentation (generating the html). So, in my servlets and filters I'll determine if the user is logged in, has permissions to view whatever page they are attempting to view, query the datastore or memcache for what the data they want to view, etc. Then, I'll forward the data to the JSP page to generate the HTML view. There's nothing that stops you from using JSPs for everything, but most programmers prefer doing the heavy coding stuff in servlets and use the JSP for what they do best which is generating HTML.
