Jakarta EE Migration
Since the 2025.Q3 release, Liferay DXP is built on Jakarta EE, the successor to Java EE 8. This lets DXP run on modern application servers such as Tomcat 10.1 and JBoss EAP 8 and keeps the platform current and secure.
It is a breaking change: custom code and some dependencies must be updated to the new standard. Liferay provides documentation and tooling that automate many of the required code changes. These answers cover the business and technical questions customers and partners ask most.
