Java development using JCICS

You can write Java™ applications that use the CICS® Java class library (JCICS) to access CICS services. JCICS is the Java equivalent of the EXEC CICS application programming interface (API) that is provided for other CICS supported languages, such as COBOL.

Using JCICS, you can write Java applications that access CICS resources and integrate with programs written in other languages. Most of the functions of the EXEC CICS API are supported. You can get the JCICS library from any of the following places:
  • Start of changeThe com.ibm.cics:com.ibm.cics.server artifact on Maven CentralEnd of change
  • The com.ibm.cics.server.jar file supplied with CICS in the USSHOME directory
  • The CICS Explorer® SDK
Mapping levels change between different levels of the com.ibm.cics.server package and the version of CICS you are using. The mappings are:
  • CICS TS 4.1: com.ibm.cics.server 1.201.0
  • CICS TS 4.2: com.ibm.cics.server 1.300.0
  • CICS TS 5.1: com.ibm.cics.server 1.401.0
  • CICS TS 5.2: com.ibm.cics.server 1.500.0
