Medusa provides a framework for implementing asynchronous socket-based servers for TCP/IP, and on Unix, Unix domain sockets. The first release includes HTTP, FTP, and 'monitor' (remote python interpreter) servers. Medusa can simultaneously support several instances of either the same or different server types - for example you could start up two HTTP servers, an FTP server, and a monitor server. Then you could connect to the monitor server to control and manipulate medusa while it is running.
JWAA is a software framework for building dynamic Web applications as networks of first-class Java objects. XML is used for representing information normally coded as HTML. The XML files are automatically reloaded when they change. It has a "persistent forms" feature in which form data automatically persists in the database such that fields behave like pieces of paper that automatically preserve what's written on them. This default behavior is easily overridden. Invalid links are reported at XML load time via the browser, and are also recorded in log files.
PasTmon (Passive Application Response Time Monitor) passively monitors your application servers, measuring and reporting user response times, throughput and congestion. It currently works with HTTP, telnet, rlogin, rsh, FTP (control channel), SMTP, POP3, and IRC. Measurements are recorded in a PostgreSQL database and are presented graphically via a PHP Web front-end using R statistical analysis scripts to create the plots.
Seminole Webserver is a portable Web server designed to be used in embedded systems, where memory space is at a premium. It is written in C++, and has a mechanism to direct requests to application-specific code, complete with the decoding of "CGI" parameters. It also includes a "filesystem" that can package up Web content (and optionally compress it) and store it in a ROM or other "flat" device. It comes with a simple example to make it a standalone Webserver under POSIX platforms for evaluation and testing.
Qexo (Query Expressions for XML Objects aka Kawa-XQuery) is an implementation of W3C's draft XML query language XQuery. XQuery is a high-level expression language whose values are sequences of nodes (as in DOM) and simple values. It includes syntax for embedding XML or HTML results, and a 'for' statement comparable to SQL's 'select'. This implementation uses the Kawa tools to compile XQuery programs to Java bytecodes that can run on any JVM. XQuery programs can run as servlets, as standalone applications, or from the command-line.
