* $Id: s.examples.README 1.5 01/03/23 22:00:32+01:00 neumann@somewhere.wu-wien.ac.at $
*
* 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
