Chapter 9. Synchronous event

processing (callback)

In many of today’s custom and off-the-shelf applications, a requirement exists to

provide an immediate, or synchronous, response to an internal event within the

application. Although this response could be fulfilled through the existing event

framework, event processing is asynchronous in nature and does not easily

allow an adapter developer to correlate an event with this disparate business

object request that can arrive later.

To overcome this issue, a new method was introduced in the Version 2.1 release

of the WebSphere Business Integration Adapter Framework that allows for

synchronous handling of requests from an application. This method,

executeCollaboration, handles the sending of the request to the broker

automatically and correlates the broker response for reply to the application,

which simplifies the coding requirements for a custom adapter.

This chapter provides details about this new method.
