Why Jakarta EE Is the Right Choice for Modern Java Applications

Jakarta EE’s Emerging Significance

When the Eclipse Foundation released the Jakarta EE 8 specification in September 2019, Java EE gained renewed relevance for millions of developers worldwide.

Adoption and Market Validation

The 2020 Eclipse Jakarta EE survey showed it become the second‑largest cloud‑native framework, with 35% of 2,200 respondents using it. McKinsey’s 2020 article “Developer Velocity: How software excellence fuels business performance” highlights open‑source software as a key driver of enterprise performance, while Red Hat’s 2020 report found 95% of 950 IT leaders consider open source very important and 77% plan to increase its use.

Deep Industry Integration

Apache Tomcat implements four Jakarta EE specifications (Servlet, Standard Tag Library, WebSocket, Authentication); Spring Boot embeds Tomcat at runtime; Eclipse Jetty implements Servlet, Server Pages, and WebSocket; and MicroProfile implements four Java EE specs and is evolving toward Jakarta EE, illustrating extensive reliance across the Java ecosystem.

Community‑Driven, Vendor‑Neutral Longevity

The Eclipse Foundation’s open, vendor‑neutral model ensures Jakarta EE‑based applications remain important and usable long‑term, with feature development driven by community demand rather than a single vendor’s roadmap.

Strategic Business Benefits

Jakarta EE accelerates time‑to‑market, improves development efficiency, and reduces costs. Its proven stability and backward compatibility are critical—90% of Fortune 500 companies still run enterprise Java, making compatibility a key investment safeguard.

“Boring Software” Philosophy

The platform embraces the “boring software” manifesto, prioritizing reliability over hype and emphasizing community‑shared best practices.

Architectural Flexibility

Developers can use a unified framework for both cloud‑native microservices and traditional monoliths, seamlessly integrating technologies such as MicroProfile, Docker, and Kubernetes, thereby leveraging existing infrastructure while building new cloud‑native applications.

Low‑Risk Innovation

Clear separation between specifications and implementations allows easy swapping of databases or application servers with minimal code impact, saving time, effort, and money while maintaining competitiveness.

Evolution Toward Jakarta EE 10

Upcoming Jakarta EE 10 will introduce additional features. Jakarta EE 9’s namespace change from javax to jakarta simplified migration and opened the path to faster certification and innovation.

Flexible Deployment Models

Developers can choose Uber JAR, Fat JAR, or Hollow JAR packaging, granting freedom and improving deployment efficiency; small payloads can be pushed to the cloud frequently, reducing operational overhead.

Rich Specification Set

Jakarta EE offers over 40 well‑designed specifications—including RESTful Web Services, Persistence, JSON Processing/Binding, CDI, Security, Bean Validation, and Messaging—that are fully integrated and interoperable, enabling developers to build complex applications with minimal boilerplate.

Vibrant Global Ecosystem

Major Java vendors such as Fujitsu, IBM, Oracle, Red Hat, Payara, and Tomitribe, along with many smaller companies, participate in the Jakarta EE Working Group, fostering a collaborative environment that drives continuous evolution.

Survey‑Backed Adoption Trends

The 2020 Jakarta Developer EE survey reported a 55% combined adoption rate for Java EE 8 and Jakarta EE 8, with Jakarta EE 8 accounting for 17% of usage shortly after its September 2019 launch. In December 2020, Jakarta EE 9 was released, marking a milestone with its namespace migration.

Opportunities for Community Participation

Joining the Jakarta EE Working Group protects strategic Java investments, influences the roadmap, and offers learning and sharing of best practices, allowing organizations to align technology decisions with business priorities.
