In addition to Web Services that call Nucleus methods, the Oracle ATG Web Commerce platform enables you to create Web Services that send JMS messages through Patch Bay. Many events in the Oracle ATG Web Commerce platform are triggered by JMS messages, so by calling a Web Service that sends a JMS message, a client can start execution of various services and processes. In particular, scenario actions are triggered by JMS messages, so you can use Web Service calls to invoke scenario actions remotely. For example, suppose a new user registers in some application, which invokes a Web Service that sends the registration information to the Oracle ATG Web Commerce platform. The client application could then call a Web Service that sends a JMS message of type atg.dps.Register into Patch Bay, thereby triggering a scenario action that (for instance) sends an e-mail message to the new user.
This section discusses how to create Web Services that send JMS messages, and how to configure components to listen for these messages. For more information about JMS and Patch Bay, see the Dynamo Message System chapter of the ATG Platform Programming Guide.
