Generally available: Java 17 and Tomcat 10.0 on Azure App Service

Published date: April 13, 2022

Earlier this year we announced that the Microsoft Build of OpenJDK was coming to Azure App Service along with Java 17 and Tomcat 10.0. These runtimes are now available on App Service to select during app creation.

Java 17

Java 17 on App Service is distributed via the Microsoft Build of OpenJDK, a no-cost long-term supported distribution of the OpenJDK and Microsoft’s new way to collaborate and contribute to the Java ecosystem. You can learn more about the Microsoft Build of OpenJDK from the documentation.

Tomcat 10.0

Tomcat 10.0 builds on Tomcat 9.0.x, supports Java 8 and later, and is the first Tomcat release to migrate from the Java EE 8 specification to Jakarta EE 9. This means that Tomcat 9.0 or 8.5 applications will require a refactor and rebuild to run on Tomcat 10.0 in almost all cases. Please refer to the official Tomcat 10.0 migration guide on the Apache Tomcat website for guidance on migrating Tomcat 9.0 and 8.5 applications to Tomcat 10.0.
