In this article, we are going to enhance the structure of the previous example, by making use of a Java Bean.
This structure enhances readability, and separates the code of the user interface from the code to perform computations.
In the case of more complex applications, the structure of the first example would lead to a solution difficult to understand and maintain. The structure of the solution presented in this article is more flexible, readable and so more easy to maintain and evolve.
So, we shall create a Net Beans project, just like in the first example, and make the same modifications to index.jsp. Then, we create the new JSP file (newjsp.jsp):
Contrary to what we saw in the First JSP Example, this file has not embedded the code to obtain the parameters or the calculation of the operation result. It has, instead, a JavaBean component that is no more than a class who are passed the parameters and performs the required calculations.
