Most Web applications require certain aspects of the system to be secured in some manner. Security requirements are often specified at both the system and functional levels. System requirements may dictate, for example, that entry of sensitive information should be performed over a secure HTTP connection (HTTPS).

One of the major benefits of using the Struts framework is its built-in interface for performing data validations on incoming form data. As discussed in Chapter 4, upon submitting an HTML form, Struts captures the form data and uses it to populate one of your application’s ActionForm subclasses (Form Bean) assigned to the form. The Form Bean’s validate( ) method is then called to perform any necessary validation of the incoming data.

One fundamental principle of programming is that, generally, it is best to swap a logic error for a compiler error. Compiler errors tend to be found in seconds and are corrected just as fast. Syntax errors are a good example. A missing semicolon can make things confusing. If the compiler error is something particularly cryptic, the resolution may take as long as a couple of minutes to discover

In this article, we will examine working with Java Stored Procedures in Oracle database.
The entire code has been tested with only Oracle 10g with version 10.2. It would also support any successive versions after Oracle 8i. But, I didn’t personally check all of those versions.
