Actually the main reason behind this when the servlet is
used for both presentation & business logic, the tight
coupling between presentation & business logic creates the
problem to the reusablity, because sometime change in
business logic tends to change in presentation logic. Apart
from that the tags & HTML like enviroment makes the webpage
more dynamic.
Now if we are using jsp page for business logic then
scriptlet will be more inside the JSP page which leads to
heavy maintaince cost. The business techies call it as
MODEL1 Architecture.
The seperate declaration of servlet for business unit will
avoid all above.Say MODEL2 Architecture.
