Abstract

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.

Claims

1. A method, comprising:

processing a Web services message within a stateless object oriented runtime environment using an instance of a stateless reliable messaging protocol, said processing comprising;

receiving a sequence identification request from an endpoint,

generating the sequence identification for the Web services message,

transmitting the sequence identification to the endpoint,

receiving the Web services message from the endpoint,

serializing message data of the Web services message and state information associated with the instance of the stateless reliable messaging protocol,

creating a messaging system message wherein the messaging system message includes the serialized message data and state information,

persisting the messaging system message,

retrieving the messaging system message,

deserializing the messaging system message, and

resuming the processing of the Web services message using the state information of the messaging system message to continue processing the Web services message from the point at which the execution was halted.

2. The method of claim 1, wherein the processing further comprises:

invoking a timer after the receipt of the Web services message from the endpoint, wherein if the timer expires the processing of the Web services message is terminated.

3. A computing system

a processor;

and

a memory coupled to the processor, the memory to store instructions which when executed by the processor cause the computing system to perform a method, the method comprising;

processing a Web services message within a stateless object oriented runtime environment using an instance of a stateless reliable messaging protocol, said processing comprising;

receiving a sequence identification request from an endpoint,

generating the sequence identification for the Web services message,

transmitting the sequence identification to the endpoint,

receiving the Web services message from the endpoint,

serializing message data of the Web services message and state information associated with the instance of the stateless reliable messaging protocol,

creating a messaging system message wherein the messaging system message includes the serialized message data and state information,

persisting the messaging system message,

retrieving the messaging system message,

deserializing the messaging system message, and

resuming the processing of the Web services message using the state information of the messaging system message to continue processing the Web services message from the point at which the execution was halted.

4. The computing system of claim 3, wherein the processing further comprises:

invoking a timer after the receipt of the Web services message from the endpoint, wherein if the timer expires the Web services processing of the message is terminated.

5. An article of manufacture including program code which, when executed by a machine, causes the machine to perform a method, the method comprising:

processing a Web services message within a stateless object oriented runtime environment using an instance of a stateless reliable messaging protocol, said processing comprising;

receiving a sequence identification request from an endpoint,

generating the sequence identification for the Web services message,

transmitting the sequence identification to the endpoint,

receiving the Web services message from the endpoint,

serializing message data of the Web services message and state information associated with the instance of the stateless reliable messaging protocol,

creating a messaging system message wherein the messaging system message includes the serialized message data and state information,

persisting the messaging system message,

retrieving the messaging system message,

deserializing the messaging system message, and

resuming the processing of the Web services message using the state information of the messaging system message to continue processing the Web services message from the point at which the execution was halted.

6. The article of manufacture of claim 5, wherein the processing further comprises:

invoking a timer after the receipt of the Web services message from the endpoint, wherein if the timer expires the processing of the Web services message is terminated.
