xLightweb is an easy-to-use HTTP network library to build high performance, highly scalable network applications in Java. xLightweb provides a simple and intuitive API to write client side HTTP applications as well as server side HTTP applications. In contrast to the Servlet API, xLightweb is not only focused on server side programming. xLightweb also supports client side programming by providing high-capacity client side classes such as an HttpClient. It supports both blocking/synchronous programming as well as non-blocking/asynchronous programming.
Chiron was written to demonstrate that you could embed special tokens in an infobots fact file so that recalling/matching a fact causes novel/interesting and hopefully useful behaviour. The 'tokens' gradually gained functionality, and now the factoids themselves are fully programmable. A tracing feature is used to automatically follow instructions, generate the code, and then learn it as a fact. There are many other features, including a hooking system for plugging multiple backend engines in to process what it sees, etc. The current problem with the program is the lack of documentation.
JaMailer is a simple email server. Although small, simple, and easy to use, it supports quite a few options for setting things like socket backlog, max client connections, max mail box size, max email size, where to drop email to unknown accounts or store in a special mailbox, and lists of accounts for which you want to log/spy on the two way communications.
JaMailist is mailing list software that is simple and easy to use. It was produced as an add-on to JaMailer and works well with it, although it should be easy to configure to work with many different setups. It's designed so that a novice can have mailing list services running in seconds.
