Mediators could access the Synapse registry to load resources and configure the local behavior. Refer to the Spring Mediator and Script Mediator implementations for examples on how this could be achieved.
Loading of Extensions by the Synapse Runtime
Synapse loads available extensions from the runtime classpath using the J2SE Service Provider model. This essentially iterates over the available JAR files, for a
