Bindings in WebSphere Integration Developer
Imports and exports in WebSphere Integration Developer need binding information. This binding information will contain the protocol or any other data required by other modules to use this export/import. The meaning of import binding is different from export binding.
Import binding talks about how to access an external service. The default binding method for import is SCA bindings.
An export binding talks about how the service will be published to other modules or other services. An export binding can be HTTP Binding, Messaging Binding(MQ Binding, JMS bindings, MQ JMS etc), SCA Binding and Web Service binding. If the modules are running in same server, it is recommended to use an SCA binding instead of web service or JMS bindings. It is more easy and fast.
