Please do not post the same question in multiple forums. This is called cross-posting. It causes confusion and duplication of effort which will annoy the people who would otherwise help you making it less likely that you will get an answer to your question.
I closed the topic in the JSP forum.
If you're not getting an answer to your question, maybe you could improve the question. We have some tips for doing so here

questions 1) and 2) are not same
1) foo.Person p = new foo.Employee(); p.setName("Evan"); request.setAttribute("person",p);
2) foo.Employee p = new foo.Employee(); p.setName("Evan"); request.setAttribute("person",p);
I guess if you visit the SCWCD forum, there is a link which leads you to the errata website. Also note that, any software book will for sure have a site dedicated to errata's. You can be doubly sure of that.
