Series: Upgrading to Jakarta EE 10

Upgrading to Jakarta EE 10 from an older version of Jakarta EE or Java EE can be a bit tricky and may require some extra attention to detail. One of the main things you may encounter is making sure your existing code and libraries are compatible. Some libraries may still be using the javax package, which can cause conflicts when trying to run your applications on a Jakarta EE server like Eclipse GlassFish 7. You might also run into problems with some deprecated APIs that were removed in Jakarta EE 10.

But don’t worry, we’ve got you covered! In this post and the future posts in this series, we’ll explain everything you need to know to upgrade to Jakarta EE 10 successfully and almost in no time.

In our previous article, we explored the initial steps of migrating Java EE 8 or Jakarta EE 8 applications to Jakarta EE 10. We transformed the final binary application using the Eclipse Transformer to deploy it on a Jakarta EE 10 runtime. Building upon that foundation, we now dive deeper into the next crucial phase of the upgrade process: transforming the application’s source code to use the Jakarta EE 10 APIs. This will enable you to use new features in Jakarta EE 10 as well as newer versions of external libraries that require Jakarta EE 10.
