Small size web app

[subba Sathi]

I would like to develop a small size web app(3-5 screens) that needs to access DB2 table in the backend..

What should be the technology used..

JSP/Servlets/java beans
Here how does the database connection happens
What is the architecture diagram look like? like presentation layer/business logic layer/data access layer etc..


JSP/Servlets/EJB - Does it need EJB for a small size app..


Please advise..

PS. I would like to know different combinations of architecture designs for various types of web applications like small, medium and large applications..

can someone guide me thru this.. i am being exposed to web technologies recently and would know JSP/Servlets only..

Presentation Layer - JSP/Servlets
Business Logic Layer - Java Beans
Data Access layer - JDBC


ThankS

Not really a JDBC question.

A small web application is very unlikely to require EJBs. Do you have specific non-functional requirements you need to meet that would suggest EJBs are a good choice?

Thanks for reply..

Not knowing EJB much, what kind of NFRs EJB supports..

What are the limitations of using JDBC as data access layer..

The screen will have read/Update records from the DB2 table..

Thanks

No offense your questions kind of large and all-encompassing, perhaps you should pick up a book or two on web applications, J2EE servers, and ejbs. I recommend the Head First series.
