The present disclosure relates generally to techniques for improving reliability of message communications. In certain embodiments, techniques are described for facilitating reliable communication of messages between a source (e.g., a client system) and a destination (e.g., a target system) via an intermediary communication handler system. In certain embodiments, a message can include a request to be communicated to a destination for a target service. An intermediary communication handler system can store information indicative of the delivery status for a message to ensure reliable communication. The information indicative of the delivery status for a message can be managed in association with a unique identifier corresponding to the message. The information indicative of the delivery status for a message may also be used to determine whether to retry communication of a message in satisfaction of reliability parameters (e.g., QoS criteria) specified for a communication protocol used for communication of the message.

Techniques for reliable messaging for an intermediary in a network communication environment

A system and method for providing asynchrony in web services, such as Java-based web services, including in some instances use of a distributed in-memory data grid. Embodiments of the system allow a client application or client to make requests upon a server application or service. A queuing feature, such as one or more Java Message Service (JMS) queues, can be used to store incoming requests at the server side, to support asynchronous behavior. In accordance with an embodiment, instead of or in addition to JMS, the system can use a distributed in-memory data grid, such as Oracle Coherence, to provide queuing functionality.
