Creating a Java Servlet Project: A Step-by-Step Guide

The purpose of this article is to provide a comprehensive guide on creating a Java servlet project that allows customers to browse and search for movie information, add movies to their shopping cart, and check out. In this project, we will focus on implementing the necessary interfaces to facilitate these functionalities.

Database Design

To begin with, let's design our database schema. We will need two tables: `movies` and `customers`. The `movies` table will store information about each movie, including its title, genre, director, and release year. The `customers` table will store information about each customer, including their email address and password.

LIKE Predicate

One of the key features of our project is the ability to search for movies using partial matching. To achieve this, we will use the LIKE predicate in our SQL queries. For example, a query asking for 'term' for the `title` attribute should return movies such as 'Terminal' and 'Terminator'. We can use the LIKE operator in combination with wildcards (`%`) to match partial strings.

Substring Matching

Another important feature of our project is substring matching. This allows customers to search for movies using a subset of characters from the movie title, genre, director, or release year. To achieve this, we will use the LIKE predicate and wildcards (`%`) in combination with each other.

Search Interface

The `Movie list` page will display the results of the search query as a table with at least the following columns: `Title`, `Genre`, `Director`, and `Release Year`. The interface can be customized to include additional columns or styles.

On the `Main` page, customers can choose either to search for movies or browse through the movie list. To log in to the system, customers will need to provide their email address and password. We will use the `customers` table for authentication, not the database login/password.

Implementation

To implement this project, we will create a Java servlet that handles HTTP requests and responses. The servlet will use JDBC to interact with our database and perform searches, retrieve movie information, and update the shopping cart. We will also use HTML forms to collect user input and display search results.

In conclusion, creating a Java servlet project requires careful planning and implementation of the necessary interfaces to facilitate customer interactions with the system. By using the LIKE predicate and substring matching techniques, we can provide customers with a robust and efficient way to search for movies.
