the difference between both commands is that the command A include the page
in translation time (when the servlet engine create the servlet from the
jsp). The command B is executed when the the servlet is executed. In other
words, if you use command A the servlet generated from test4.jsp will be
inserted inline in the servlet of the parent page. If you use command B the
servlet generated from parent page include un forward to test4.jsp using the
dispatcher.
