This sample demonstrates how to link to a Spring Boot application running in a CICS Liberty JVM server from a CICS program. It is based on a Spring MVC application that provides both a web front-end and a CICS entry point using the Link to Liberty @CICSProgram annotation. The sample shows how both entry points can share the same application state.
Select the branch for your target environment:
| Spring Boot | Branch | Min Java | Jakarta EE | Build Status | |
|---|---|---|---|---|---|
| 4.x | springboot/v4 | 21 | EE 11 |  |
|
| 3.x | springboot/v3 | 17 | EE 10 |  |
All branches target CICS TS V6.1 or later.
⚠️ Thespringboot/v4branch is a work-in-progress preview. It targets Spring Boot 4.x and Jakarta EE 11, which requires Libertyservlet-6.1support — not yet available in CICS TS. It is not yet recommended for use.
