Binding information determines how a service connects to and interacts with an application. Specifically bindings are the protocols and transports assigned to imports and exports.
Your applications connect to services through a binding.
Bindings are a critical part of your import and export components. Bindings determine specifically how your import and export components interact with clients outside the module which contains the import and export components. The bindings specify the message format and protocol details for a particular interface.
Use JMS bindings if reliability is an important issue for you. Asynchronous communication using messaging queues is often preferred in business processes where reliability is critical. There is a pairing of import and export components with JMS bindings as you would expect from a message consumer and producer.
IBM® Web Services bindings can also by used with import and export components.
In the case of an import component only, a stateless session enterprise Java™ bean (EJB) binding can be used.
The key bindings when it comes to EIS systems are JMS bindings and EIS bindings.
JMS bindings are used from a module to a module; that is, you can create an export component in a module with a JMS binding or you can create an import component in a module with a JMS binding. You cannot do this with an EIS binding. Since JMS is used for asynchronous communication, you can also use JMS as the binding between an external messaging source and a component in a module.
EIS bindings are used from an EIS system to an application or vice-versa. In the first case, you would develop an export component with an EIS binding. In the opposite case you would develop an import component with an EIS binding. Essentially, EIS bindings are used to access external EIS systems or for external EIS systems to access applications deployed in WebSphere Process Server.
