The setLogging method is straight out of the examples:
private void setLogging() {
Properties props = new Properties();
FileInputStream istream = new FileInputStream(configFile);
props.load(istream);
istream.close();
PropertyConfigurator.configureAndWatch(configFile, 3600000);
// will check for config changes every hour
} // .. setLogging()
In my production method I've added validation and exception handling
code, but these are the functional log4j statements.

Please respond to

Thanks for the help!!!
But can you be a little more specific regarding the method like
setLogging()??

Another approach is to write the initialization servlet to work both
at initialization and when invoked as a normal application servlet.
I did this by writing the init method as:
public void init() {
locateConfigFile(); // establishes the String containing the
fully qualified config file name
setLogging(); // loads the config file with
PropertyConfigurator
} // .. init()
and the "normal" servlet methods as:
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
doService(request, response);
}
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
doService(request, response);
}
private void doService(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
// other code for determining where to dispatch to
setLogging();
// dispatching code
}
Then the servlet can be used to reconfigure logging upon demand when
invoked as a normal part of the application - I use it as part of the
admin functions.
I hope this helps.

Maybe PropertyConfigurator.configureAndWatch helps you.
