JSP2JSF Performance Test

A focused migration lab comparing a legacy JSP/JSTL dashboard with an equivalent Jakarta Faces (JSF) component-based dashboard.

Objective

Make the JSP-to-JSF modernization story concrete: keep the underlying data and user-facing functionality equivalent, replace view composition with component-based JSF, and establish a disciplined performance measurement process.

Architecture

• Shared model/service: DashboardData and DashboardService feed both views.
• Legacy JSP: src/main/webapp/jsp/dashboard.jsp uses JSP/JSTL.
• Modern JSF: src/main/webapp/jsf/dashboard.xhtml uses Jakarta Faces components and a view-scoped backing bean.
• Benchmark: performance/benchmark.md defines a reproducible comparison protocol.

Run

Requirements: Java 17+ and Maven 3.9+.

mvn clean package

Deploy target/jsp2jsf-performance-test.war to a Jakarta EE 10-compatible runtime and open both endpoints.

Performance story

Run the benchmark under controlled, identical conditions and record the measured results in performance/benchmark.md.

Portfolio framing

Built a comparative Java web application demonstrating migration from JSP/JSTL to JSF, introduced component-based views, and established a reproducible benchmark for validating frontend render-time improvements.

Constraints

• No GitHub Actions.
• No external database is required.
• Both implementations render the same representative dashboard data.
