I would suspect that your problem lies in one of two areas:
1) Your web app is not configured correctly. 2) You're not using a build of Tiles 2 that is compatible with the version of Struts. I didn't see the exception you posted so it's hard to determine which. I'll check the archives if I get a chance today. Most people seem to be finding success by following the example of the tiles-test webapp: http://svn.apache.org/repos/asf/tiles/framework/trunk/tiles-test/ and: http://svn.apache.org/repos/asf/tiles/framework/trunk/tiles-test/src/main/webapp/WEB-INF/web.xml HTH, Greg
