Abstract: The .NET attributes bridge in accordance with the present invention provides a simple way to develop distributed middleware applications for the .NET platform with little or no programming. .NET provides a mechanism to extend the meaning of code with metadata with the use of attributes. The present method, system and program provide a set of attributes, which can be used to declaratively specify what features of the middleware API to enable. These features include, but are not limited to, sending and receiving reliable or certified messages, enabling fault tolerant operation, or leveraging distributed queues. As a result, a programmer can leverage the functionality of products of multiple vendors' middleware without having to learn the respective APIs.

Abstract: The method in accordance with the present invention allows any user to compose and transmit email messages using the resources native to the user's computer. In particular, the user can utilize a PDA as a wireless email antenna to transmit messages composed on an attached device, such as the user's laptop or desktop computer without having to directly connect to the Internet, thus providing mobile connectivity, personal resource accessibility and real-time PDA/PC synchronization.
