A service application has an associated Service Component Architecture (SCA) module.
You deploy service applications, to WebSphere Process Server,
within EAR (enterprise archive) files.
The kind of SCA modules that enterprise service bus supports
are called mediation modules. Mediation modules allow
you to change the format, content or target of service requests.
Deploying a service application
The process of deploying
an EAR file containing a service application is the same as the process of
deploying any other EAR file. You can modify values for mediation parameters
at deployment time. After you have deployed an EAR file containing an
SCA module, you can view
details about the following.
- The service application.
- The SCA module associated
with the service application.
- You can see how an SCA module is
connected to service requesters and service providers. SCA modules are
connected to service requesters through exports, and to service providers
through imports.
.
Viewing SCA module details
The
SCA module details
that you can view include some of the following. The precise details you can
display depend upon the
SCA module.
- SCA module name.
- SCA module description.
- Associated application name.
- SCA module imports.
- Interfaces.
- Import interfaces are abstract definitions that describe how an SCA module accesses
a service.
- Bindings.
- Import bindings are concrete definitions. They specify the physical mechanism
by which an SCA module accesses
a service. For example, using SOAP/HTTP.
- SCA module exports.
- Interfaces.
- Export interfaces are abstract definitions that describe how service requesters
access an SCA module.
- Bindings.
- Export bindings are concrete definitions. They specify the physical mechanism
by which a service requester accesses an SCA module,
and indirectly, a service.
- SCA module properties.
