Let's get started. I'll use Maven for this purpose. Create the standard Maven directory structure

This is a script to tail a log file through the web browser. It uses AJAX, apache web server, mod_python, UNIX utilities tail (requires the --lines switch) and wc . The log file may reside on the web server or any other host accessible from the web server through SSH. Although it's written in python, it should be easy to port to other languages such as Perl. Apache httpd.conf :
LoadModule python_module modules/mod_python.so ...Python script:
