About the technology
JSF in practice
Jakarta Faces, also known as JSF or JavaServer Faces, is a server-side Java web framework for building form-heavy business applications. It helps teams create reusable UI components, manage view state, and wire pages to Jakarta EE services.
Typical deliverables
- Internal portals and admin tools
- Workflow and approval screens
- CRUD interfaces with validation
- Component-based page templates
- Integrations with existing Java back ends
When specialists help
Companies bring in freelance JSF experts when older applications need repair, extension, or a cleaner structure. That is common in Berlin teams that run long-lived enterprise systems and need support without replacing the whole stack.
Ecosystem and tooling
Strong JSF professionals work with Jakarta EE, Facelets, CDI, JPA, and component libraries such as PrimeFaces or OmniFaces. They also understand managed beans, converters, validators, navigation rules, and the trade-offs of server-side rendering.
What strong work looks like
Good experts keep views predictable, reduce duplicate markup, and avoid fragile page logic. They test navigation, state handling, validation, and integration points carefully. They also know when JSF fits and when a lighter web layer is the better choice.
Hiring signals
- The app uses JSF 2.x or Jakarta Faces already
- Forms are hard to maintain or extend
- Legacy pages need safer updates
- The team needs help with migration or cleanup
- Remote work is fine, but some Berlin projects benefit from close workshop sessions
Frequently asked questions
Need clarity? These are the questions we hear most often about Jakarta Faces.
Jakarta Faces is used to build server-side Java web interfaces, especially business apps with forms, tables, wizards, and validation-heavy screens. Teams use it for internal tools, portals, and enterprise applications where component reuse and stateful pages matter.
Yes. JSF is the common abbreviation, and JavaServer Faces is the older full name. Today the Jakarta EE name is Jakarta Faces, but many teams still use the older terms when they talk about existing applications.
Jakarta Faces keeps more view logic on the server and works well when the back end already lives in Jakarta EE. Compared with Spring MVC, it is more component-driven; compared with modern front ends, it usually needs less JavaScript but gives less client-side flexibility.
A strong Jakarta Faces specialist usually also knows Jakarta EE, CDI, JPA, Facelets, and component libraries such as PrimeFaces or OmniFaces. Database access, validation, security, and integration with existing Java services are often part of the same work.
JSF projects often need someone who has already worked with stateful server-side pages and legacy Java stacks. Simple fixes may be enough for small tasks, but larger modernization or migration work needs deeper knowledge of component lifecycles, navigation, and integration points.
Yes. Jakarta Faces work is often done remotely because the main tasks are code changes, reviews, and testing. For Berlin companies, a hybrid setup can still help when teams want workshops around legacy screens, architecture decisions, or migration planning.
Look for clear answers about view state, navigation, validation, and component reuse in JavaServer Faces applications. Good specialists can explain how they would debug broken pages, reduce duplication, and keep old screens stable while making targeted improvements.
Jakarta Faces is often worth keeping when the application is already stable, the team understands the stack, and the business need is focused on extending existing screens. Replacing it makes more sense when the UI layer is too hard to maintain or the product needs a very different client-side experience.
