JSP is again a servlet which is having HTML syntax with java support.All the code that is written in JSP willbe converted finall into Servlet.
A single servlet cannot respond each and every client request such as Add,delete,update,Search therefore the request and response object is passed onto different servlets with little task completed by each servlet. This controlling part is easier to write in java.As Servlet contains the pure java code and coding is needed to generate the proper user response. So Servlet is used as controller.
