How to access config file kept in WEB-INF folder

Question

I am new to groovy. and looking for a way to store common configs at one place so my application can access it.

I am keeping configurations for my groovy applications in WEB-INF, how can I access the file from my main application?

I tried this ConfigSlurper().parse(new File("config.groovy").toURL()), but can't get it working, because the path where tomcat is expecting the config.groovy is where tomcat is installed. I have my appBase configured to some other location.

How do I give relative path to new File('') so that it can read the config file?

You want to do this using the ClassLoader and not the filesystem directly. Basically, don't use File. I'm not sure how to do this in Groovy, but in plain-old Java it would look like this:

URL config = request.getServletContext().getResource("/WEB-INF/config.groovy");

... then do whatever you want with the URL. (FYI the getResource method uses the ClassLoader of the webapp). So, maybe in Groovy that might be:

ConfigSlurper().parse(request.ServletContext.getResource("/WEB-INF/config.groovy"))

Sorry I can't give you the exact Groovy syntax... not my world. :)
