You can use the SIS REM module to view, remove, configure, or create extension references.

What are SIS extension references?

An extension reference identifies an extension component. There are two types of extension component supported by the SIS:

  • service composition selection extension component, used during the triggering phase

  • interceptor extension component, used in composition interceptors.

SIS extension components are implemented as JAIN SLEE services, and an extension reference identifies an extension component using its SLEE service component identifier.

For details, see Managing Extension References in the SIS Administration Guide.

To manage extension references:


From the SIS instance page, select Extension Refs.

A list of Extension Refs installed in the selected instance displays.
