If your organization has built or customized solutions on Liferay DXP, the upcoming migration from javax.* to jakarta.* namespaces is a critical change that demands attention. This guide outlines what the transition means, why it matters and how Proventeq can help you prepare your Liferay platform for long-term success.
 

What’s changing and why it matters

As part of the Java EE transition to Jakarta EE under the Eclipse Foundation, all enterprise Java APIs are moving from the legacy javax.* namespace to jakarta.*. Liferay DXP is aligning with this shift with future versions no longer supporting javax.*.

For Liferay customers with custom modules, integrations, or extensions, this change is significant. It affects:

  • Custom code referencing javax.* packages

  • Third-party libraries and connectors

  • Compatibility with upcoming Liferay DXP releases

  • Security and maintainability of your platform


Key timeline: Q3 2025 and beyond

Liferay has confirmed that starting Q3 2025, all new versions will require the jakarta.* namespace. If you're planning to upgrade or maintain compatibility, your platform must be migrated before this deadline.

While the Q1 2025 LTS release will still support javax.*, it may not align with your long-term goals, especially if you're aiming to adopt new features, improve performance, or move toward cloud-native architecture.


What this means for your Liferay implementation

  • Custom portlets or modules

  • Extended service layers

  • Integrated third-party systems

  • Legacy Java EE components


Common challenges in the migration process

Liferay customers often encounter:

  • Difficulty identifying all javax.* dependencies
