Reading config.xml from jarfile
Hi,
Is there somebody out there which can provide an example of how I can
load a XML config file from a jar?
The idea is to add i.e. appl.xml to a jar and call
DOMConfigurator.configure("appl.xml") within the application.
I would like to hide part of the configuration from the end-users to
avoid that they make changes to parts of the configuration.
Other ideas are welcome as well.
Another path I walked was to do the 'hidden' part within the code, but I
could find a way to add the rendering info into th repository. So, ideas
or hints on how to do that are welcome as well.
Thanks
-- Eric.

Now I understand why my question didn't show up in log4jxx-user.
I posted the question to log4cxx-user, but configured my news reader to
only fetch log4jxx-user. (Sorry about that)

Thanks for pointing me in the correct direction.

I'll repeat the reply that I sent when you asked this on log4cxx-user:

Did you have a problem with this approach? Your code should look
something like (omitting exception handling code and not checked for
syntax):
String pathInJar = "/appl.xml";
URL configURL = getClass().getResource(pathInJar);
if (configURL != null) {
DOMConfigurator.configure(configURL);
}
FYI: The URL returned from getResource() would look something like
"jar:file:///pathtojar/jarfile.jar#/appl.xml".
