Hi,
I was just wondering if you really have to use a physical configuration file
.....
I mean , If it were just for the information that you want from the outside ....
you can use the initArgs variable in your zone.properties file (if you are using
Apache and I am sure other servlet engines also have a configuration file wich
serve this purpose )
and have your servlet program read that variable for use.
The snippet goes like this ....
servlet.ServletClassName.initArgs=name=value;
and the Servlet code would be :
getServletConfig().getInitParameter("name");
That's just about it for something like passing your drivername,jdbc url etc.
And you can have multiple distinct name's name=value pairs in the configuration
files.
Hope that helps
Rishi.
PS - If you have all the reading of initialization parameters in the init section
code you can refer to it from all your instances .
