I've got a small problem, couldn't find anything about it:
I'm using TomCat (6.0.20) in Eclipse Europa with WTP. I want to write some small servlets with database access where I want the db information provided by properties-files.
My problem is the following: How can I deploy those resource files so I can find the properties-files in a relative manner? I have tried to include them in the src-directory, as external files, add them to the build path, ... But I don't know where I should put them or how I should publish the small web project to be able to relatively access the resource files. Can someone give me hints on what to do here?

Who is calling the backend object, and is it and/or the backend object
part of the web application?
The point is that ServletContext.getResource(),
ServletContext.getResourceAsStream(), Class.getResource() and
Class.getResourceAsStream() can all provide access to a resource within
a web application using a "path" that is guaranteed to work regardless
of deployment. Assuming the backend object is part of the web
application, a ServletContextListener could pass a ServletContext to the
backend object during web application initialization, or read the
properties and pass a Properties object.
