Main reasons for using servlet as a controller in struts. why not jsp..

Answer / srinu

jsp means very less code in java.and also their is no tags
for intigrate with other logic.i.e means controll with
other logic just like as connection polling,data accessing
object,persistance logic.suppose u take as jsp as
controller programmer feels lot of complexity.Hence
industry recomended struts as controller.in servlet easy
intigrate with other logic.
Industry recomended as MVC rule servlets as controller,jsp
as view layer.

Answer / rajesh r

As per the Jsp spec we should limit the scriptlets usage.

and Jsp is designed for presentation(VIew) part based on

Answer / christ

If JSP's are using as a controller, then we should break the
rule of MVC. Which is the base for using struts. MVC is used
to divide the application into three part(model part, view
part and controller part). So that in future if we want to
change the view, then you do not need to do much work on
your logic part.

Lifecycle callback annotations are invoked at any time during the processing of an action. 11.Which of the following are the features of the new unified Expression Language?
