Re: How do I do to change the properties file forlog4jintoanother directory?
getting resources from WEB-INF is specific to a servlet application. If
you need to get the config file from both places, then put your config file
back into WEB-INF/classes/config. At that point, the code below will work
and you can change your path in the servlet example to this...
context.getResource(/WEB-INF/classes/config/log4j.properties);

Using your suggestion, I have able to make my Log4j servlet reading the

I know this is a bit out of track, but in another java bean file, I am
using InputStream. Is it a way to change to use the URL just like the
Log4j method which you have pointed out? as I am not able to get it read
from /WEB-INF. Thank you.

It would help if you actually obtained your servlet context. Right
now, it
is null.
ServletContext context = this.getServletContext()

You need to look at my code closer. context is a ServletContext.
You
can use it to access stuff anywhere in the webapp.
URL url = context.getResource(/WEB-INF/config/log4j.properties);
PropertyConfigurator.configure(url);
And, of course, you can also use the InputStream way if you want, but
the
URL way is a bit simpler.
One thing to note. In my original code, I had forgotten to prefix
WEB-INF
with a /. That is fixed in the code above.
