As an aside, there is no need for the cast to "String", as the return
type is already "String".

I often see people doing the same with "request.getParameter()".  I can
only guess that people get into the habit of putting the cast to "String"
when using "session.getAttribute()" (where it is needed), and extend
that to other servlet methods.
