Upgrading to Jakarta EE 9 or newer from an older version of Jakarta EE or Java EE can be a bit tricky with the
javax to jakarta prefix change. Some libraries may be still using the javax package, which can cause conflicts when trying to run your applications on a Jakarta EE server like Eclipse GlassFish 7. You will likely encounter the same issues when upgrading to Spring Framework 6 or Spring Boot 3, Quarkus 3, and newer versions of many other frameworks, which now depend on Jakarta EE 9 APIs.
But don’t worry, I’ve got you covered! In this post, I’ll explain everything you need to know to upgrade to Jakarta EE 9+ successfully and in almost no time. By Jakarta EE 9+, I mean either Jakarta EE 9 or 10, which is currently the latest version of Jakarta EE.
