JShell is a UNIX-like shell written in Java, and intended primarily for working with Java programs. It was written to simplify Java development on Psion's 5mx, but can be used with any JDK 1.1.x (or higher) JVM on Windows, Linux, or other Unixes. JShell's features include directory commands (ls, cd, pushd, popd, dirs, etc.), examining and setting environment variables, Java compilation and execution (compilation is done using javac), piping and redirection, support for background jobs (running and killing jobs in the background), and command recall (history, !!, !).
WebTTS is a WWW-based trouble ticketing system designed for businesses that need to track problems in their network, schedule system maintence, and track general customer problems. Most large businesses use a tracking system to help deal with customer problems, but these systems are either non-free, custom written, or simply impossible to install and get working in a reasonable amount of time.
