Develop a robust, enterprise-grade server-side application using Java Server Pages (JSP) and Java Database Connectivity (JDBC) to manage profile modifications for university students (e.g., IGNOU BCA/MCA Students). The application must implement a unified dynamic lookup interface that accepts either a unique Student Enrollment Number or a registered Mobile Number as an input token. Upon successful verification of the student, the interface must securely expose and permit modifications to the student’s data, specifically communication address, mobile contact number, and verified email etc. You need to explicitly state your database schema definition and connection configuration assumptions before presenting the source code.
ii. Design and develop a highly secure, multi-layered RESTful or MVC web application implementing full CRUD (Create, Read, Update, Delete) lifecycle workflows using Spring Boot and Hibernate/JPA frameworks. The system will serve as an automated portal for Online Registration and Fee Payment for an industry-level workshop on "Web Technologies". Furthermore, implement rigorous security configurations (such as Spring Security protocols) to enforce Authentication and Role-Based Access Control (RBAC), while ensuring that updates or deletions to registration rows are structurally validated and restricted according to payment settlement status etc. Make necessary assumptions and list them.
A robust server-side application for student profile modification using JSP and JDBC requires a secure architecture consisting of Presentation Layer (JSP), Business Logic Layer (Java Servlets), and Data Access Layer (JDBC). The application allows students to search their records using either the Student Enrollment Number or Registered Mobile Number. Appropriate input validation, prepared statements, session management, and exception handling ensure secure operation. Assumptions: Database: MySQL named studentdb. Table: students. Connection URL: `jdbc:mysql://localhost:3306/studentdb` Username: `root` Password: `root` Database Schema: ```sql CREATE TABLE students( enrollment_no VARCHAR(20) PRIMARY KEY, student_name VARCHAR(100), address VARCHAR(255), mobile VARCHAR(15) UNIQUE, email VARCHAR(100) ); ``` Connection Configuration: ```java Class.forName("com.mysql.cj.jdbc.Driver"); Connection con=DriverManager.getConnection( "jdbc:mysql://localhost:3306/studentdb", "root","root"); ``` The JSP page accepts either Enrollment Number or Mobile Number. ```html ``` The Servlet performs ________ _____ ________ ____ __________ ______ _______.
