Craving to deploy your Cloud Foundry applications on Tomcat 10 runtime and make use of the latest and greatest Jakarta EE technologies? Got an app using Spring Boot and had to upgrade it to version 3.x due to Spring Boot 2.x EoL? Version 2.x of SAP BTP Security Services Integration Libraries is no longer sufficient as your applications require version 3.x?
No more wait and fear! SAP Java Buildpack 2 is here!
NOTE: - This new major version of SAP Java Buildpack co-exists along with its older counterpart - from now on referred to as SAP Java Buildpack 1 (SJB 1).
- We highly recommend that you migrate your Java applications to SJB 2 as soon as possible as SJB 1 will be removed from SAP BTP, Cloud Foundry landscapes on June 30, 2025.

Now, let's take a closer peek at the core features of SAP Java Buildpack 2:
- The first release provides support for Java 17 (via SapMachine JRE 17).
- You can deploy Java applications on Tomcat 10.1.x. It implements Servlet 6.0, JSP 3.1, EL 5.0, WebSocket 2.1, and Authentication 3.0 specifications (the versions required by the Jakarta EE 10 platform).
- You can use version 3.x of SAP BTP Security Services Integration Libraries.
- Our plans are to gradually add support for Java 21 as well as the latest version of the Apache TomEE runtime (adding support for even more Jakarta EE technologies).
UPDATE! Effective April 4, 2024, SAP Java Buildpack 2 now supports Java 21. See: Release Notes
UPDATE! Effective February 20, 2025, SAP Java Buildpack 2 now supports TomEE 10. See Release Notes and blog post TomEE 10 has landed in SAP Java Buildpack 2!
