I didn’t see anything in the cgicc page about connected to a java backed.
Parsing a log file every time the cgi script is run will have some limitations:
-it will be hard to know how far back to process (drivers will update as they
see fit, and might not log anything)
-adding support for streaming binary data will be very complicated
-the cgi script will hold duplicate (and possibly outdated) information that is
already held in the drivers
You might be better off using a library that allows direct access to java
(something like http://php-java-bridge.sourceforge.net/pjb/how_it_works.php).
This way the cgi program can issue a direct call to
Coordinator.getRunningDrivers() to get a list of drivers running, and a direct
call to each drivers getWidgetXml() to get the XML data. This way no parsing is
needed, and the drivers do not need to log anything beyond
debugging/warning/error messages. The coordinator will always have up-to-date
information on what drivers are running, and the drivers themselves will always
have the most recent information on the remote modules they control.
Keep in mind that java already includes a built in simple http server
(http://docs.oracle.com/javase/7/docs/jre/api/net/httpserver/spec/com/sun/net/httpserver/HttpServer.html).
It would be pretty simple to parse GET requests and return the results of the
methods above. User verification could tie in with the mysql database.
