On the right side, under the Communications heading, expand the Messaging TAB and click the Message listener service link.
There is a single message listener service and a single corresponding thread pool in each server for all the listener ports defined in that server and used by all the applications.
If we have enough threads in the message listener service thread pool, then we will see four threads processing messages in parallel.
Access to the WSDL of the notification listener service can be provided when the provider's web service is deployed or at runtime by passing a reference to the WSDL on the initial request.
Target (Servlet and MBean) : Provides inbound listener services for transport and document protocols from internal and external endpoints as well as transport-level security functions.
