Cannot deploy warble war

I am trying to use Tomcat7 from within IDEA, starting it using a war generated by Warbler. Tomcat is starting but failing to deploy the war correctly with error messages like

java.io.FileNotFoundException: WEB-INF/lib/properties/myfile.properties (No such file or directory)
java.io.FileNotFoundException: WEB-INF/config/database.yml (No such file or directory)

Those files are in the WAR but not in the exploded directory under ~/.IntelliJIdea11/system/tomcat

Any ideas?
