A system and method are provided to perform tentative updating for transactions using the Web Services Reliable Messaging protocol. From a protocol layer of a client side web services framework persists a message from an application transaction (a reversion message) in a persistent storage unit. The web services framework forwards the reversion message as a reliable message to a transport layer to cause a recipient to revert to a state prior to the application transaction, if a triggering event occurs in the web services framework. If no triggering event occurs a confirmation message is forwarded as a reliable message to confirm receipt of the tentative update at the transport layer. Concurrently with the confirmation persisted reversion message is deleted from the persistent storage unit.

Method for processing of application transaction in a web services framework

A method and a system that incorporate Web services reliable messaging in a Web services client application via an application programming interface (API). The method includes obtaining a Web services proxy object from the client application and using this object for creation of a logical sequence from a sequence factory. The Web services client application transmits a reliable message sequence to the Web services provider based on the logical sequence.

Method and a system for incorporating reliable messaging in web services client applications via an API

A method and system for processing Web service messages within an object oriented runtime environment is described. In one embodiment, the method includes steps for invoking a single instance of a state-less protocol for processing inbound and outbound flows of Web services messages. After determining Web services messages have been received out of order, processing of the outbound flow of any remaining messages is suspended until a complete set of messages is received. The messages are rearranged into proper order before completing processing of the outbound flows of the remaining messages.

Method and system for implementing built-in web services endpoints

A method and system for implementing Web service built-in endpoints is described. In one embodiment, the system includes a built-in endpoint manager interface and a built-in endpoint implementation container.

A method is described that involves processing a Web services message within an object oriented runtime environment. The processing involves executing a plurality of protocols to support a Web service that the message pertains to. Each one of the protocols perform one or more operations that contribute to a different part of the processing. The executing involves a first of the protocols receiving from an object WS Addressing information retrieved from the message's header. The executing also involves the first protocol providing the WS Addressing information to a second of the protocols. The executing also involves the second protocol providing the WS Addressing information to at least one of: a third protocol of the protocols; a component that performs an endpoint method of said Web service; software that identifies a new transport level destination address for said message.

WS addressing protocol for web services message processing runtime framework

A system and method for the lifecycle of a protocol processing a message is described. In one embodiment, in a stateless object-oriented runtime environment, an instance of a reliable messaging protocol is used to process a message. The processing including receiving a message and performing operations based on said message.

Runtime execution of a reliable messaging protocol

Method and system for processing single WS-RM sequence by a plurality of clustered application server instances, sharing persisted RM sequence data related to WS-RM protocol. The common RM sequence data, associated with a plurality of RM requests is cached in a buffer that is associated with an application server instance. An independent messaging system is associated with the application server instance to handle RM common data persistence in WS-RM protocol implementation.
