for details regarding deployment), one of
the main things to address is how to manage and configure properties for binding
components packaged inside them. Binding components are network protocols
and mechanisms connecting your composite to external services, applications,
and technologies (such as messaging queues, databases, web services, and so
on). Binding components in Oracle SOA Suite 11g are of two kinds:
•
Services:
Services provide an entry point to the composite and advertise their
capabilities to external applications by exchanging their service metadata in-
formation through a WSDL file. The service bindings define how a client ap-
plication can invoke a composite. Examples of service bindings from the sales
order composite in the preceding screenshot are an HTTP-based web ser-
vice, JCA-based file polling service, and a Direct Binding service.
•
References:
References enable message exchanges between composites
and externally deployed services. Examine the sales order composite dia-
gram in the preceding screenshot to see how an HTTP-based third party web
service, JCA-based database adapter, and
Web Service Invocation Frame-
work (WSIF)
type notification service act as reference bindings in the com-
posite assembly.
Configuring and managing service bindings
Oracle Enterprise Manager Fusion Middleware Control allows you to perform ser-
vice binding administration tasks such as attaching policies, managing errored
out messages, and setting binding properties. Depending upon your preference,
there are two available mechanisms to configure binding properties. The property
