Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
JFileUpload is a Java applet that allows uploading of files and folders to any Web or FTP server. This component can be integrated into any application, whether the server-side technology is JSP/Servlet, PHP, Coldfusion, CGI, or Microsoft ASP. The front-end provides an upload progress bar, a cancel button, and drag-and-drop support. JFileUpload supports very large uploads over 2GB and can resume broken uploads. Its colors, size, and language can be customized.
htrosbif is a tool that actively probes an HTTP server. It prods the Web server in all sorts of old, new, basic, fancy, spec-compliant, and spec-breaking ways. It tries to characterize both the well-spoken educated responses and the seriously deviant babble it receives in return. Signatures contain no user data, only header names and HTTP-level quirks. As a useful side effect, this might detect reverse proxies, HTTP load balancers, intrusion prevention systems, and Web application firewalls.
Syncless is an experimental, lightweight, non-blocking (asynchronous) client and server socket network communication library implemented in Stackless Python 2.6. It contains an asynchronous DNS resolver (using dnspython) and an HTTP server capable of serving WSGI applications. It aims to be a coroutine-based alternative of event-driven networking engines (such as Twisted and FriendFeed's Tornado). It is already about that fast, but it has fewer features and is less stable now.
