loading configuration on startup

Hey all,
were did i load my own configuration on startup ?

for example the log4j configuration.

I tried to extend the actionservlet and wrap the init method's, but i didn't
receive the init Parameters from web.xml ;-(
Servlet for beginners ?!??

thanks Fredy

Hi

Log4j 1.2.7 can load log4.xml from your classpath

Or you can use jakarta commons-logging, which will load your log4j.xml
automaticaly too

I can't see why can you not pick up the init-params in your serlvet's init()
method. It's so easy.
For each servlet I wrote I provide the config parameter which is an xml
file.
This xml is parsed with Digester.
This is how I do it, and do not be surprised if you see some coincidence
with
the ActionServlet's init() method...

    public void init() throws ServletException {
        String value;

        try {
            LOG.debug("start init");
            // Initialize the context-relative path to our configuration
resources
            value = getServletConfig().getInitParameter("config");
            if (value != null)
                config = value;
            // Acquire an input stream to our configuration resource
            InputStream input =
getServletContext().getResourceAsStream(config);
            if (input == null)
                throw new UnavailableException
                ("config file '" + config + "' is missing");

            Digester digester = null;
            digester = initDigester();
...


Hth,

It is loaded automagically supposing that the log4j.properties resides on
your
CLASSPATH.
