Why the European Accessibility Act matters for you?

From 28 June 2025, the European Accessibility Act will apply to a wide range of digital products and services including websites, mobile apps, ticketing systems, and e-commerce. Meeting these requirements not only ensures compliance but also creates more inclusive experiences for all users. Aligning with the Act helps organisations avoid potential penalties, legal challenges, or market restrictions, while strengthening brand reputation and customer trust.

Meeting EU accessibility rules usually means following WCAG guidelines (e.g., EN 301 549). Vaadin components are built to meet WCAG 2.1 AA and EU requirements, so buttons, menus, and page layouts work well for people with different abilities. This lets developers create apps that are accessible from the start, without having to rebuild features or add complicated fixes later.

Solution

Ready to migrate your legacy Java applications?

The Vaadin Modernization Toolkit converts old UI code into Vaadin Flow (Java web) without losing the structure, names, or comments you already have. Your team gets clean, familiar code from day one, with no extra “translation” layers to slow things down. The updated app runs on modern Vaadin, so it’s faster, easier to maintain, and ready to work with today’s tools and security standards. You also get built-in mobile-friendly layouts, accessibility support, and a smoother path for future updates.

Step 1: Migrate onto accessible building blocks

Move your legacy Java UI to Vaadin’s WCAG-aligned components that are manually tested with assistive technologies. This eliminates many inherent barriers typical in legacy desktop UIs moved to web.

Step 2: Apply patterns that map to EAA outcomes

Use component features (focus management, ARIA hooks, keyboard navigation, contrast-safe theming) to meet user-journey needs (forms, tables, dialogs, charts). Link to docs patterns.

Step 3: Verify & document

Run automated checks and manual assistive-tech passes; export an accessibility test log + remediation notes for internal compliance files (maps to EN 301 549 evidence).

Step 4: Close gaps

If your app has custom behaviors, Toolkit Fine-tuning extends transformations to raise automation %, keeping your migration accessible by default.

Fine-tuning: Reach your target automation with a fixed-price guarantee

The engineers at Vaadin offer a fixed-price Fine-tuning service to improve the Standard Rules, Custom Rules, and Feature Pack to reach a higher degree of automation for your application. The transpiler can also be iteratively improved to automate a higher percentage of the work.
