IBM WebSphere Multichannel Bank Transformation Toolkit, Version 7.1

Context hierarchy

The contexts used in the application are arranged in a hierarchy starting at the server root context. The root context, in addition to maintaining session tables for all the clients that connect to the server, keeps all the resources (data and services) to be shared by all the processes and operations launched from any session established with the server.

Whenever a session is established on the server, the startUpHtmlSessionOp operation creates an htmlSession context and chains it to the root context. This session context keeps all the resources that operations and processors used during the user session. Services must be properly attached to this context so that they are created only when the session is created instead of being created whenever the user requests an operation.

The toolkit chains all operations and processors used during the session to their own copy of the session context. These contexts store data for the operations and processors. Note the externalized context files should not explicitly chain the contexts for operations and processors.
