Rule Definition
Struts is a Framework for building Model-View-Controller 2 Web applications. This model is the Blueprints recommended architectural design pattern for interactive applications. It separates design concerns (data persistence and behavior, presentation, and control), decreasing code duplication, centralizing control, and making the application more easily modifiable. MVC 2 also helps developers with different skill sets to focus on their core skills and collaborate through clearly defined interfaces.

Remediation
Review the design to follow this principle.
