What are you referring to? CRUD operations to a database? Because that's the only thing I can think of where CRUD actually applies (you don't delete objects in Java; that's what the gc is for).

Perhaps you could clarify.

Isn't it funny how there's always time and money enough to do it WRONG?

I was asking for sample CRUD operation programs which are made using JSP, Servlet and JavaBeans.

Your question doesn't make sense.

As Winston pointed out you don't say what want your CRUD operations to operate on. A MySQL database? Oracle database? List? Map?
The technologies you say you want to use, JSP, Servlet, and JavaBeans, make no sense in this context. They all are used for different reasons, none of which are related to a CRUD API.

Please be much more specific in what you are asking for.

I think the poster means using JDB (or JPA) from a servlet. If one doesn't know about databases yet, those terms wouldn't come up yet.

Rajnish: If that's the case, asking for an example is premature. First you need to learn about databases. Try the JDBC tutorial to get started.
