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.
