Abstract: A method, apparatus, and system for providing a standard, generic contract between an application server and a message provider which allows the message provider to deliver messages to message endpoints (each of which is associated with a corresponding message application) residing in the application server is disclosed. By generic, it is meant that the contract is independent of the specific messaging style, messaging semantics and messaging infrastructure used to deliver messages. In this way, the contract also serves as the standard message provider pluggability contract that allows any message provider to be plugged into any application server via an associated resource adapter.

Abstract: A method, apparatus and system arranged to provide a connection(s) from an application component to a shared resource only as needed. In this way the total number of connections are limited to only those connections required to execute a particular method thereby saving valuable computing resources. In the described embodiment, after an invoked application component has started a particular transaction, a pre-enlistment notification is returned to the application server thereby putting all resource adapters on notice that a connection may be forthcoming.
