with appearance of mobile devices such as cell phones, PDAs and smart phones, context-aware applications are becoming increasingly popular. Therefore, developers are always seeking for new and powerful developing tools for context-aware programming. Developers prefer to use fast and convenient development tools that can support all required possibilities for implementing a complete and user-friendly context-aware systems. In this paper, we determined some essential principles for developing and implementing context-ware applications. Technologies for context-aware applications programming should support these principles. Among different technologies, we introduced four technologies, which are most practical for developing context-aware applications based on determined principles. Java agent development environment, java context-awareness framework and J2ME are java-based technologies, which were studied in this paper. We also introduced spring.net technology as a new technology for designing context-aware application because of its novel features that can present an easy interactive and easy developing area for context-aware applications. Eventually, the proposed context-aware framework for an intelligent university mobile organizer by using spring.net technology is illustrated. This framework draws on spring.net components for developing a context-aware application.
