About the technology
Enterprise foundation
Jakarta EE is the open standard for building secure, modular enterprise applications on the Java platform. It provides specifications for web interfaces, REST APIs, dependency injection, persistence, transactions, messaging and security. The technology is used where reliability, maintainability and integration matter across long-lived business systems.
Core capabilities
Jakarta EE specialists work across the application layers and choose the right specifications for each service. Their work commonly includes:
- Designing RESTful services with Jakarta REST and JSON processing
- Building server-rendered applications with Jakarta Faces
- Managing persistence with Jakarta Persistence and transaction boundaries
- Connecting systems through Jakarta Messaging and enterprise integration
- Applying authentication and authorization with Jakarta Security
Runtime ecosystem
Jakarta EE applications run on compatible runtimes such as Payara, Open Liberty, WildFly and GlassFish. Professionals also work with CDI, MicroProfile, Maven, Gradle, container images and Kubernetes when services need cloud-native deployment. They understand application servers, configuration, observability and the migration path from older Java EE systems.
When expertise matters
Companies bring in freelance Jakarta EE expertise when an enterprise system needs a controlled change without disrupting critical operations. Typical needs include modernizing Java EE applications, splitting selected services, improving performance, connecting legacy databases or preparing a move to managed infrastructure. In Austria, specialists may also support distributed teams working across German- and English-speaking business environments.
Delivery and collaboration
A strong professional turns business rules into clear service boundaries, testable components and documented interfaces. They can review an existing codebase, plan incremental migration and coordinate with security, database, frontend and operations teams. Remote delivery works well when repositories, environments and decision processes are organized; on-site workshops can help with complex legacy landscapes.
Quality signals
Look for practical evidence rather than familiarity with specification names alone. Strong specialists explain trade-offs between Jakarta EE, Spring and lighter runtimes, keep transactions and security explicit, and test integration behavior under realistic conditions. They should be comfortable with code reviews, automated builds, production diagnostics and clear handover documentation.
Frequently asked questions
Curious about Jakarta EE? Here are the answers that come up again and again.
Jakarta EE is used to build secure, transactional enterprise applications and APIs on the Java platform. It fits systems such as customer portals, financial services, insurance workflows, supply-chain applications and internal business platforms that require reliable integration and long-term support.
Jakarta EE offers standardized specifications that can run across compatible application runtimes, while Spring provides a broad framework ecosystem with its own conventions and tooling. The right choice depends on existing investments, runtime preferences, team skills, operational constraints and the level of vendor portability required.
A strong Jakarta EE specialist usually understands Java, SQL, relational database design, REST, messaging and automated testing. Experience with CDI, JPA, Maven or Gradle, containerization, Kubernetes, CI pipelines and identity standards is valuable for modern delivery.
The answer depends on the system’s risk, age and integration depth. A small API extension may need focused Jakarta EE knowledge, while a migration or mission-critical platform calls for a professional who can assess architecture, application-server behavior, transactions, security and release risks.
Jakarta EE work is often suitable for remote collaboration because code, tests, documentation and deployment pipelines can be shared digitally. On-site sessions may still help when specialists must inspect legacy environments, run stakeholder workshops or coordinate closely with teams in Austria; German or English may be required depending on the organization.
Java EE is the former name of the platform before stewardship moved to the Eclipse Foundation and the Jakarta EE name was introduced. Migration can involve namespace changes, runtime compatibility, dependency updates and specification differences, so a specialist should first map the application and its deployment environment.
Ask for examples of systems they have delivered, the runtime technologies involved and the risks they managed. A capable Jakarta EE professional can explain design decisions clearly, demonstrate testing and observability practices, and show how they handle security, transactions, integration failures and maintainable handover.
Jakarta EE remains relevant when teams want open standards, mature enterprise capabilities and freedom to choose a compatible runtime. Its ecosystem also connects with MicroProfile and cloud-native practices, making it suitable for both established applications and carefully designed new services.
