Job Description

Scope:

The Office of Information Services is requesting evaluation and proof of concept of a replacement of the existing eXPRS Java Struts framework and introduction of a new, modern, responsive UI framework. eXPRS currently uses an outdated version of Java Struts that lacks modern features and best practices and has known vulnerabilities. Struts has its own set of maintenance challenges. Over time, eXPRS has grown in technical debt, slowing down maintenance and debugging. Managing Struts-based code has become overly cumbersome, causing the eXPRS M&O backlog to grow and become difficult to manage at the speed for which the business is requiring.

Other problems with Struts include:

• Struts follows a tightly coupled architecture, where changes in one part of the application can impact other parts.
• Struts doesn't seamlessly integrate with other technologies like ORM (Object-Relational Mapping) or dependency injection.
• Struts lacks robust tag libraries for creating dynamic views. Developers often end up writing custom tags or using JSP (JavaServer Pages) directly.
• Struts can become a bottleneck in high-traffic applications due to its heavyweight nature.
• Struts-based applications might lack modern UX features, such as responsive design, dynamic content loading, or smooth transitions.

Introducing a new UI framework will enhance user experience, improve maintainability, increase performance, strengthen security, reduce technical debt, align with current best practices, and offer better community support.

Other advantages of moving to a more modern UI framework include:

• Modern UI frameworks provide loosely coupled modules. This modularity allows developers to work on specific components without affecting the entire system.
• Newer frameworks offer better integration options, making it easier to work with databases, APIs, and other services.
• Modern UI frameworks provide better support for templating engines, making view development more efficient.
• New UI frameworks are designed with performance and scalability in mind, optimizing resource usage and handling concurrent requests efficiently.
• A new UI framework allows developers to create engaging and user-friendly interfaces.
• Newer frameworks prioritize security and provide better mechanisms for input validation, authentication, and authorization.
• A modern UI framework typically offers better developer tools, IDE support, and faster development cycles.
• Developers can focus on business logic rather than dealing with framework intricacies.

The proof of concept is intended to evaluate the existing Struts application to understand its architecture, components, and dependencies, identify the target UI framework, and prove the new architecture that will be used across the entire eXPRS application. The following activities will be completed as part of the proof of concept:

• Research alternative frameworks or technologies that can replace Struts. Consider factors like community support, features, and ease of migration.
• Select a representative part of the eXPRS application to work with during the PoC.
• Install necessary tools, libraries, and dependencies for the new framework (e.g., Spring Boot, Micronaut, or another choice).
• Adapt the existing Struts code to the new framework. Replace Struts-specific components (e.g., actions, forms, and configuration files).
• If the new framework offers additional features, implement them in the PoC.
• Ensure data flows correctly between the new components.
• Evaluate the security features of the new framework. Test for vulnerabilities and ensure proper input validation.
• Write unit tests for the migrated components.
• Test interactions between the new components and existing ones.
• Assess the performance impact of the replacement.
• Work with key OIS technical architects, and lead staff to ensure the new framework adheres to OIS standards, allows for long term maintainability, flexibility, expansion, and portability.

Tasks:

• Develop and deliver updates to eXPRS application to introduce new modern UI framework. This includes software code changes and documentation.
