Mvc1 no concept of controller, view directly interacts with model.
This makes both view and model tightly coupled, thereby multiple view technologies are not leveraged. All three factors are opposite in
Mvc2. Mvc2 controller concept is introduced, where it plays a centralized role. Controller is configured to spit any of the predefined
view technologies to name HTML, XML, JSP, WML etc. Controller is also configured on the model it can interact with. Model represents
business layer, so it could talk to any data model like business components (EJBs), JDBC to interact with any database or say Hibernate
Webservices etc. All client requests are configured to land at controller, so it could check security, logging, session handling. Since
servlet is best bet having these characteristics, servlet controller component is introduced in Struts.

According to MVC 2 model View should not know about the model and model should not know about view, both has to be totally independent from each other and servlets serves the purpose of interface between these two bridges because of its powerfull APIs.

 Nice question .

The MVC -2 has decided to use controller as struts and jsp as views because , the view of a site may change from time to time , so its best to keep JSP as view as no need to recompilation of JSP .

The servlet is taken as a view it should be recopiled everytime according to client.

According to MVC2 the purpose of addition of the controller was to just separate the dynamic part of the application from the static part and for that the dynamic part given the name "view" is handled as
JSP's . while the static part as controller (servlets), but we could have used JSP instead of servlets as it may rise some benefits too,
