Its for reusability purpose.jsp should be only used for
presentation purpose and our html designer,who later design
the page is not aware of java coding will not be comfortable.
and writing all buiseness logic in servlet lets the code
reusable.and for writing buiseness logic in jsp page there
are some other way like using scriplets.so why do the job
with less profit and extra work.

Answer / nishant
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.

Answer / gopika
In layman's terms, JSP is core Java embedded in HTML. Servlet has HTML embedded in core Java. You must be aware that HTML is used to define the page structure of a web page at the client side and it deals with how to present the data in a web page. The purpose of JSP introduction is to add very few lines of core Java to help display the web page at the client side and hence, populating many lines of core Java is not appreciated in JSP.
