Don't download beta8 of hibernate tools - that's old ;) Get beta9a if you want the latests release OR get the nightly build which will have much better integration with latest seam-gen since it automatically picksup the configuration and setup the needed things for hibernate tools too shine. Look here for the nightly http://download.jboss.com/jbosside/builds/nightly/ and tools.hibernate.org for the latest release if you don't like to use nightlies.
