Abstract: Methods, systems, and computer program products for selecting messages in an enterprise computing environment are described herein. In one embodiment, a method is provided for selecting one or more of a multitude of messages in an enterprise computing environment. The method comprises forming a message-selector chain from a plurality of message selectors, each of the message selectors identifying at least one criteria, and using said message-selector chain to select one or more of said multitude of messages that satisfy the message selector chain. In this embodiment, using said message-selector chain to select one or more of said multitude of messages includes identifying a first of the multitude of messages that satisfies a first of the message selectors, and selecting one or more of the multitude of messages that has a defined relationship to said first of the messages and that satisfies a second of the message selectors.

Abstract: In the context of middleware products, an arrangement wherein a sender tags messages with authorization information identifying those users or groups who are authorized to view or receive the messages. Thus, even if multiple users will be connected to the same queue for reading messages, only specific receivers/consumers will be able to get the messages. Not only is a comfortable degree of security ensured, but the need to waste system resources, e.g., by using multiple queues for different kinds of messages, is summarily avoided.
