Systems and methods for providing targeted event notifications to subscribers are disclosed. In an example embodiment, events may be received from a publisher. The events may be categorized into a plurality of topics. The events may be distributed among brokers to process a topic selected from the plurality of topics based on the events. Further, it may be determined whether the topic exists in a list of topics handled by the brokers. Authentication credentials of the publisher may be validated, based on the determination. Based on the validation, queues of the events may be formed based on an order of receipt of the events. The events present in the queues may be filtered based on subscriptions of the events. For the fileted events, targeted even notifications may be forwarded to the subscribers.

Subscription based event notifications

Systems and methods for filtering and routing event notifications to subscribers are disclosed. In an example embodiment, events from a publisher may be received. Each of the events may be associated with a topic, and the topic may be compared with topics present in broker metadata cache, based on one of prefixes and a fast lookup technique using a hash-table. Further, it may be determined whether the topic associated the events is present in the broker metadata cache based on comparison. Based upon determining, matching nodes for the events may be retrieved. Further, the events may be routed based on routing tables and availability of the matching nodes. Based on the routing, the events may be forwarded to the subscribers.

Routing and filtering event notifications

Systems and methods for dispatching targeted event notifications to subscribers are disclosed. In an embodiment, the system includes a receiver to receive events from a publisher. The system further comprises a router in communication with the receiver to route the events. The system further comprises a director to forward the targeted event notifications to the subscribers based on the routing. The director receives a delivery status of the targeted event notification from the subscribers. The delivery status includes one of success in receiving the targeted event notification and failure in receiving the targeted event notification. The director receives an event notification with the delivery status as failure in receiving the targeted event notification. The director places the targeted event notification in a delayed queue indicative of events to be delivered after a predefined time. The director re-transmits the targeted event notification to the subscribers based on the delayed queue.

Event delivery

Systems and methods for dispatching targeted event notifications to subscribers are disclosed. In an example embodiment, a notification indicating creation of an even subscription by a subscriber may be received. An event source may be invoked to enable publishing of events corresponding to an event topic associated with the event subscription. A response from the event source for publishing of the events may be received and targeted event notifications may be forwarded to the subscribers on receiving the response.

Managing subscriptions for event notifications

Dispatching an incoming message from a queue into message transfer session(s) from which message consumers may draw messages. The message is reversibly received from the queue, whereupon a context of a message is identified. If the context correlates to an existing message transfer session, the message is ultimately assigned to a message transfer session. If the context does not correlate to an existing message transfer session, a new message transfer session is created, and the message is assigned to that new message transfer session. Upon receiving an acknowledgement of successful processing of the message, the removal of the message from the queue-like communication medium is assured. Upon receiving an acknowledgement of unsuccessful processing of the message, the message is restored to the queue-like communication medium.

Queue dispatch using deferred acknowledgement

A business process adapter converts a SOAP (Simple Object Access Protocol) message into a business process message. A body path and a node encoding type are defined for the business process adapter. And, when the SOAP message is received, the business process adaptor extracts the node of the SOAP message at the location defined by the body path and encodes the node according to the defined node encoding type. Additionally, the business process adapter converts a business process message into a SOAP message using a defined content encoding type and a defined format of the SOAP message. When the business process message is received from the business process management server, the business process adapter encodes the body of the business process message according to the defined content encoding type and generates the SOAP message from the encoded body according to the defined format.

Efficient marshalling between soap and business-process messages

A system and method for creating a metadata endpoint for a generic data service provided by a first Service Oriented Environment (SOE) is disclosed. The first SOE is an SOE in which a process that hosts the runtime environment of the data service normally exposes a data endpoint for the data service but does not normally expose a metadata endpoint for the data service. In accordance with one embodiment, the metadata endpoint is created as part of a separate process than the process that exposes the data endpoint. The system and method advantageously enables the data service of the first SOE to be utilized by data services in a second SOE in which both a data endpoint and a metadata endpoint are normally exposed for a data service.
