The present invention is directed to a system, method, and computer-program product for protecting messaging consumers. According to one embodiment of the invention, a method for protecting messaging consumers can be provided. The method can include intercepting a message prior to arrival at a destination, comparing the message to one or more known message structures to determine the message structure, and determining if a message has a valid message structure for the destination. Intercepting a message prior to arrival at a destination may intercepts a message on a queue before the message is consumed by a consumer. Comparing the message to known message structures compares a message to message schemas, for example, XML schema, Java object definition or C structure format.

Method and system for protecting messaging consumers

A method of queuing messages for communications between a first computer program and a second computer program, comprises: placing a plurality of messages in a queue, wherein each message has a message body; placing selector information on each message, wherein the selector information contains information as to which message is to be processed next; and using the selector information on a message to identify a next message for processing.

Message ordering using dynamically updated selectors

After a client device issues a request, a verification stub component receives the request. Then, the verification stub component obtains a current state of the client device from a client state table. The verification stub component evaluates whether the request is valid or not by analyzing a content and context of the request and checking the request against a protocol matrix. If the request is valid, the verification stub component updates the current state of the client device in the current state table, and forwards the request to a server device. Otherwise, the verification stub component creates a report describing the request is invalid, and evaluates whether the server can process the request. If the server cannot process the request, the verification stub component interrupts the request and forwards the report to the client device. Otherwise, the verification stub component provides the request to the server device.

Method and apparatus to enable protocol verification

A method and system for preserving a message ordering while processing message are discussed. A message ordering manager records an order in which electronic messages arrive at an input queue. An application server processes the electronic messages out-of-order or in parallel. The message ordering manager commits the processed electronic messages in the order in which electronic messages arrive at an input queue. If a processed message cannot be committed because older message(s) are not completely processed, then application server determines whether processing older message(s) is critical or not. If the processing the older message(s) is critical, the application server rolls back the processed message and the older message(s). Otherwise, the message ordering manager commits the processed message before the older electronic messages are committed.
