Language Environment support for Java
Language Environment® is a prerequisite for Java™ programs that run in JVMs in CICS®. However, unlike the other languages, Java programs do not require the CICS-Language Environment interface.
Java programs run with Language Environment support using MVS services, not CICS services. Java programs require the Language Environment support provided by the SCEERUN and SCEERUN2 libraries only, which can either be defined in the CICS STEPLIB or included in the MVS linklist. The SCEERUN and SCEERUN2 libraries must also be added to DFHRPL.
