Why Jakarta EE Migration is Critical for Enterprise Java

The transition from Oracle's Java EE to Eclipse Foundation's Jakarta EE represents the future of enterprise Java development. My migration work keeps your applications current, secure, and maintainable while taking advantage of the latest enterprise Java features.

Namespace Migration

Complete migration of javax.* packages to jakarta.* across your entire enterprise application ecosystem, including third-party dependencies and custom libraries.

  • • javax.servlet to jakarta.servlet
  • • javax.persistence to jakarta.persistence
  • • javax.ejb to jakarta.ejb
  • • Custom library updates

Application Server Migration

Migrate from legacy Java EE application servers to modern Jakarta EE 9/10 compliant servers with improved performance and cloud-native features.

  • • WebLogic to WildFly/Payara migration
  • • WebSphere to Open Liberty
  • • Tomcat EE upgrades
  • • Configuration modernization

Dependency Management

Update build configurations, Maven/Gradle dependencies, and third-party libraries to ensure compatibility with Jakarta EE specifications.

  • • Maven/Gradle configuration updates
  • • Third-party library compatibility
  • • Build pipeline modernization
  • • Dependency conflict resolution

Testing & Validation

Comprehensive testing strategies to ensure your Jakarta EE applications maintain functionality while gaining access to new enterprise features.

  • • Automated regression testing
  • • Integration testing suites
  • • Performance benchmarking
  • • Security validation

Cloud-Native Transformation

Transform traditional Jakarta EE applications for cloud deployment with containerization, microservices patterns, and modern DevOps practices.

  • • Docker containerization
  • • Kubernetes deployment
  • • Microservices extraction
  • • Cloud-native configuration

Developer Training

Comprehensive training for your development teams on Jakarta EE concepts, new features, and best practices for ongoing development.

  • • Jakarta EE fundamentals training
  • • Migration best practices
  • • New feature workshops
  • • Development process updates

My Jakarta EE Migration Roadmap

1

Current State Analysis

I analyze your existing Java EE applications, identifying current specifications, custom extensions, and third-party dependencies. My assessment includes compatibility analysis for Jakarta EE migration and identification of potential challenges.

2

Migration Strategy Planning

Based on the analysis, I create a detailed Jakarta EE migration strategy with timeline estimates, risk mitigation plans, and a phased approach that keeps the business running throughout the transition.

3

Namespace & Dependency Migration

I systematically migrate all javax.* imports to jakarta.*, update build configurations, and resolve dependency conflicts. This includes updating Maven/Gradle files and making sure all third-party libraries are Jakarta EE compatible.

4

Application Server Upgrade

I migrate your applications to Jakarta EE 9/10 compliant application servers, update configurations and deployment descriptors, and make sure performance holds up on the new runtime.

5

Thorough Testing

Rigorous testing makes sure your migrated Jakarta EE applications keep all their functionality while gaining new platform capabilities. I run unit testing, integration testing, and performance validation.

6

Production Deployment & Tuning

I manage the production deployment with careful monitoring and provide performance tuning recommendations. I make sure the transition goes smoothly, with full documentation and knowledge transfer.
