You don't seem to understand the architecture.
Servlets serve HTTP requests, they're not tied to HTML clients like
browsers, they're tied to HTTP clients (which is what a browser is).
All you have to do is get your C app to generate an HTTP request.
That's not difficult. It simply has to open a TCP socket on the server
(which is beyond the scope of this forum) and send the correctly
formatted HTTP request string down it.
To request an index.html file you might send this over the socket:
GET /index.html HTTP/1.0\r\n
\r\n
The server will then respond with the data.
Basically that's it.
If you need more info try reading some of the stuff on HTTP. There's
a lot of it about. Or look at the source code for one of the free
servlet engines.
