Software is open source.
In order to run, Resin needs JDK 1.1.x or 1.2, and supports development for both Windows and Unix platforms. Generally speaking, Resin has two major configuration options. It can serve either as a standalone web server or as a servlet engine running in conjunction with an external server. Resin provides auto-compilation functionality for JSP, Servlets and Beans. This obviates the need for make systems.
