摘要:
Client/server middleware processes a source code client application program so that when the application program signifies the beginning of a transaction using a transaction begin command, the transaction is automatically created locally for a recoverable client and remotely for a non-recoverable client. The source code client application program can thus be written without regard to whether the transaction will be created locally or remotely, the middleware takes care of this function.

Methods, systems, and products are disclosed in which port type agnostic proxy support for web services intermediaries is typically provided by receiving in a web services intermediary a request for execution of a web services operation, wherein the request includes parametric information from which an endpoint for a target service that supports the operation can be identified; identifying, in dependence upon the parametric data, the endpoint for a target service that supports the operation; creating a target service request for execution of the operation on the target service; and issuing the target service request to the target service. Exemplary embodiments typically also include the return path of request-response processing receiving in the intermediary a response from the target service; creating in the intermediary, in dependence upon the response from the target service, a response from the intermediary, and returning the response from the intermediary to the requesting client.

A method, system and computer program for addressing a web service defined by a service definition document, such as a Web Services Definition Language (WSDL) document. The method includes, for example, generating a messaging destination for a service element, and each associated port element, of the WSDL document, and providing an invocation mechanism associated with each port destination for invoking the web service. A destination is an addressable location in the messaging configuration, such as a message queue.

The present invention provides a method, apparatus and computer program product which enables a web service gateway or web service server to provide a document, such as a WSDL, describing a target service to a requesting client which contains details which have been tailored for that client. For example, for a target service which provides access at different qualities of service, a WSDL can be returned in response to a client request, the WSDL containing details of how to access the target service at an appropriate quality of service for a user id which was specified with the client request.

Methods, systems, and products are disclosed in which port type agnostic proxy support for web services intermediaries is provided generally by receiving in a web services intermediary a request for execution of a web services operation, wherein the request includes parametric information from which an endpoint for a target service that supports the operation can be identified; identifying, in dependence upon the parametric data, the endpoint for a target service that supports the operation; determining whether the request requires a synchronous response; creating a target service request for execution of the operation on the target service; issuing the target service request to the target service; and waiting for a response from the target service if the request requires a synchronous response.

A method and system for implementing a Restart Service for the Object Transaction Service are described. The present invention provides a method and system which trigger restart of an OTS instance upon system recovery or upon system failure. The Restart Service runs independently of the client or server processes which it restarts. When a client or server enters a pending state for a transaction, a permanent record containing information to allow the OTS instance to be restarted is stored in a Restart Repository. In the event of system recovery being needed, or of a system failure, a Restart Daemon reads information from the Restart Repository and recreates the process context. The Recovery Service is initialized and log data replayed to a Transaction Manager to determine the outcome of pending transactions. Failed objects and instances of the OTS are restarted.
