This paper describes the design and implementation of the platform independent, distributed input method architecture for the Internet, Network Computer, and Java. The architecture and its framework covers wide range of input method service providers and consumers, such as Java, JavaOS, language engines, etc. The framework also includes the Internet/Intranet Input Method Protocol - the platform independent input method protocol, enables the network-based, distributed and scalable input method service by utilizing the existing platform dependent input method implementations. This paper will specially cover how Java supports input method as one of the case study.
