Raspberry Pi Java Web (http) Server

Welcome to Raspberry Pi Java Web Server.
This java web server's program is written by fully java code,
then you can have a java program (class or java main program) excute directly
on the Raspberry pi machine from a remote PC browser.
Of course, html files and image files viewing are able.

But, viewing the html files and image files are not an main purpose.
You can easily develop a java cgi program on a developper machine and easily run java cgi program on a Raspberry pi machine.
and develop a java program to access to Raspberry pi hard wear,such as GPIO.
and can easily establish Server and Client java program.

And,perl cgi excution is available (v1.4 update 2014.1.26).
Above,java class pre loading is supported (v1.5 update 2014.1.30).
I think, class pre loading is a little bit faster than other.


Java http server's setting is very simple and prepare of starting is easy.
The interface between Java http server and java cgi program is very simple and easy.

Target Server machine is Raspberry Pi (Raspbian).
Developping Server machine
CentOS 5.X , Eclipse 4.3 and jdk1-7.
Developped and written by Net-Mall Tosa.
