You don't choose one or the other. You use both to their best advantages.

Perhaps, this article on web application structure might be helpful.

And quite possibly you should use neither.
If you need to ask this question that's the most likely answer and you should tell them you don't have the skills to complete the project.

hello arun, to begin with, i am an amateur, and have just started a project. i have tried my best to answer.

MVC pattern would be the answer to your question. leave all the business logic to model(POJC, EJB), presentation logic to jsp, and control(servlet) as a mediator between view and model. Though you can call model from view, it' a bad practise.
Think of jsp as a dymnamic HTML page that clients see(ofcourse, that what they are developed for). with dynamism comes the scripting. don't use secripting in jsp, use ELs, tags etc.,instead.

so, to epitomize, use all the three (jsp, servlet, and POJC or EJB).

thank you and see if it's enough, else reply.


have a great day,

Use Servlets to handle the incoming request, inspect the request, and figure out what the heck the client wants you to do.

Use a JSP to format a nice HTML or WML page to be sent back to the user.

If it's not control logic, which sho uld be in the Servlet, or display logic that should be in the JSP, use a JavaBean or POJO or even an EJB.

You can do it, dude!

Here are some good multimedia presentations on creating Servlets and JSPs using WSAD and IRAD. Even if you're not using those tools, the code still applies.

Good luck!
