WebObjects
WO

    Apple Computer, Inc.'s application
   server framework for developing dynamic web applications.

   WebObjects applications accept HTTP requests either directly
   (usually on a specific port) or via an adaptor that sits
   between them and the web server.  Adaptors are either CGI
   programs or web server plug-ins (NSAPI or ISAPI).

   The server processes special tags in HTML pages to produce
   dynamic but standard HTML.  Tools are provided to easily set
   and get object properties and invoke methods from these tags.
   Applications can maintain state over multiple HTTP
   request-response transactions (which are intrinsically
   stateless).  Applications can also use Apple's Enterprise
   Object Framework object relational mapping libraries for
   object persistence and database access.

   WebObjects was originally based on Objective C and a simple
   scripting language but now is more likely to be used with
   Java.  Versions are available for OS X, Windows and
   Unix.

   Apple acquired WebObjects from NeXT, along with Steve
   Jobs.
