junixsocket is a Java/JNI library that allows the use of Unix Domain Sockets (AF_UNIX sockets) from Java. In contrast to other implementations, junixsocket extends the Java Sockets API (java.net.Socket, java.net.SocketAddress, etc.) and even supports RMI over AF_UNIX. It is also possible to use it in conjunction with Connector/J to connect to a local MySQL server via Unix domain sockets.
The Fressia Project is an effort to develop a framework for testing automation. It's intended for users (testers) who want a simple tool that can be used just out of the box. It was originally conceived as part of the QA efforts at the US National Optical Astronomy Observatory. It has been delivered to the community because, despite it still being at early stages, it has proven to be a useful general purpose testing tool. It is designed to provide functional testing, system testing, system integration testing, white (black) box testing, automated regression testing, acceptance testing, etc.
