The ConnectionRequestInfo interface enables a resource adapter to
pass its own request specific data structure across the connection
request flow. A resource adapter extends the empty interface to
supports its own data structures for connection request.
A typical use allows a resource adapter to handle
application component specified per-connection request properties
(example - client ID, language). The application server passes these
properties back across to match/createManagedConnection calls on
the resource adapter. These properties remain opaque to the
application server during the connection request flow.
Once the ConnectionRequestInfo reaches match/createManagedConnection
methods on the ManagedConnectionFactory instance, resource adapter
uses this additional per-request information to do connection
creation and matching. |
