* $Id: examples.README,v 1.1.1.1 2004/05/23 22:50:39 neumann Exp $ * * This directory contains several simple ActiWeb introductory examples * * * 4 Variations of the counter theme: * 1) Counter.xotcl (22 lines) The class counter is a special HtmlDocument that is made active by adding methods to the document. After starting the program, you can call it from your web browser: http://localhost:8090/counter-1.html http://localhost:8090/counter-2.html 2) Counter2.xotcl (32 lines) The Class Counter is a special WebAgent, with a plain/text interface. Additionally it has an HTML Facade that shields the sub-system and allows to access the web agent with an HTML presentation. The plain/text interface is: http://localhost:8091/c1 http://localhost:8091/c2 The web facades are: http://localhost:8091/web-c1 http://localhost:8091/web-c2 3) Counter3.xotcl (28 lines) This example demonstrates how an existing business logic (here: a small Counter class) can be enhanced with a web representation. A class WebCounter inherits from Counter and from HtmlDocument. The two web counter instances are accessible via: http://localhost:8093/c1 http://localhost:8093/c2 4) Counter4.xotcl (33 lines) The Counter class and a derived persistent counter are independent of any web usage. Two instances c1 and c2 -- that are inpendent from the usage as web counters -- are created. Two proxy object w1 and w2 handle the HTML decoration and forward the calls to the persistent counter instances c1/c2 as the real subjects for handling the calls. Only the proxies are exported, because c1/c2 can not be reached via the web server. Calls: http://localhost:8094/wc1 http://localhost:8094/wc2 * * A simple Multiple Choice Test: MC.xotcl * The multiple choice test implements a simple test and evaluation and a web facade for the test. Calls: http://localhost:8092/Gustaf.html http://localhost:8092/Uwe.html
