Introduction to Service Activator
The purpose of this example is to demonstrate how the WSO2 ESB could be used to implement Service Activator EIP allows an application to design a service to be invoked both via various messaging technologies and non-messaging techniques. Service Activator will interface interfaces methods and services which are in the back-end service layer . Using the Service Activator so that the back-end services can be filtered and displayed to the client. For more information, refer to http://www.eaipatterns.com/MessagingAdapter.html.

Example Scenario for the EIP
In the given This example it scenario demonstrates how WSO2 ESB can be used to activate only a specific amounts of services, which are exposed in the a back-end Axis2 server. Using the publishWSDL the service WSDL file was modified to filter out only a specific amount of services. The ability of the ESB to create proxy services will allow the client to invoke the ESB proxy instead of invoking the service in Axis2 server.
