A single web service may communicate with multiple clients at the same time, and it may communicate with each client multiple times. In order for the web service to track data for the client during asynchronous communication, it must have a way to remember which data belongs to which client and to keep track of where each client is in the process of operations. In WebLogic Workshop, you use conversations to uniquely identify a given communication between a client and your web service and to maintain state between operations.
Conversations are essential for any web service involved in asynchronous communication. This includes web services that communicate with clients using callbacks or polling interfaces, and web services that use controls with callbacks.
The following sample web services use conversations:
