We can write any Java Logics in our JSP. Then why we are
using servlets(Controller Layer) to interact with the DAO ?

Answer Posted / babu

ya u can write your java logic's Jsp or u can use Jsp action
tags to implement the business logic. But if u do like this
your source code may be viewed and used by the others, for
restricting or preventing your source code we are using mvc
architecture like in struts so that's why we don't want to
write java code in Jsp.
