J2EE Settings - Including additional files

I am using IDEA 4.5 witht he fairly default J2EE web app settings for building and running my webapp in Tomcat. Everything works fine except now I have added hibernate to my project and I need to place some XML files to be deployed into the WEB-INF/classes folder. But I can't figure out how to tell IDEA to include those files when running the webapp.

Am I going to have to switch to a custom ANT build to do this? I don't mind doing that, I would just like to know before I spend too much more time trying to figure this out.

Thanks.
