This project aims to demonstrate the construction of a web application for indexing PDF files using Struts2, Apache Tika, Hibernate, and Wildfly 10.

This web application provides functionalities for indexing PDF files, including:

• Uploading PDF files for indexing
• Extracting text content from PDF files using Apache Tika
• Storing metadata and extracted text content in a database using Hibernate
• Searching indexed PDF files

The project utilizes the following technologies:

• Struts2: A web application framework for developing Java EE web applications.
• Apache Tika: A content analysis toolkit capable of extracting text and metadata from various document formats, including PDF.
• Hibernate: An object-relational mapping (ORM) library for the Java language.
• Wildfly 10: A lightweight, flexible, and modular application server for Java EE applications.

• Struts2 Actions: Actions for handling user requests and interacting with the backend services.
• Apache Tika Integration: Integration of Apache Tika for extracting text content and metadata from PDF files.
• Hibernate Entities: Entities representing the data model for storing PDF file metadata and text content.
• User Interface: Basic user interface for uploading PDF files and searching indexed PDF files.

To enhance security and manage authentication and authorization, you can set up a JDBC Realm on Wildfly 10. Follow the steps outlined below:

1. Create Security Domain:

   We create a security domain named booksRealm, configuring it to use a default cache type for enhanced performance.

2. Configure Authentication:

   Within the booksRealm security domain, we configure the authentication method as classic, indicating traditional login-based authentication. Two login modules are defined:

   • Database: This module handles authentication by querying a database. It requires specifying the JNDI name of the datasource (java:/jdbc/booksDS), along with SQL queries to retrieve user credentials and roles. Password hashing is performed using the MD5 algorithm with BASE64 encoding.

   • RoleMapping: This module maps roles retrieved from the database to application roles defined in a properties file. The path to the properties file containing role mappings (booksRealm.properties) is provided, along with an option to replace existing roles.
