Janus SOAP and Sockets Demo
This page is a demonstration program for
Janus Sockets
and
Janus SOAP.
Janus Sockets is a product that provides socket connectivity
between Model 204 and many other tcp/ip bases services. Sockets are the low-level
connection underlying http, ftp, telnet and most other internet services.
SOAP (Simple Object Access Protocol) is a stateless, one-way message exchange
paradigm on which more complex interactions can also be built.
SOAP envelopes contain
XML InfoSets,
and much of the Janus SOAP API is centered on structuring XML documents.
The program that generates this page opens socket connections to other 204
onlines at Sirius Software to check whether they're running.
The remote online responds by sending a short XML document
via Janus SOAP.
The XML is parsed, also via Janus SOAP functions, and the information is
presented here:

This program that responds to the socket call is a small apsy subsystem that
responds by sending an XML document. This code can be seen
