The World Wide Web (WWW) is rapidly evolving from a platform for serving up static documents to a platform for deploying distributed, cross-platform, and language and location independent applications. There is thus a need for appropriate frameworks that would allow not only the deployment but also the development of such applications. In this paper, we describe the Web Request Broker (WRB), a system developed here at Oracle that provides a distributed, scalable, and daemon-independent framework for developing and deploying distributed web-based applications and the advances in application development that it allows. The framework description is along three dimensions. The first dimension is the overall architecture of the WRB. The next dimension is the application programming interface (API) offered by the WRB to applications, and the final dimension is the kinds of programming paradigms that can be used with the above API to develop applications.
