The validate works. So I switched trunk to use HASingletonProfileManager instead of HASingletonDeploymentScanner. One concern with the validate is you can get unsatisfied dependencies. Say you have a war in deploy-hasingleton. And say during the 'all' profile deploy the cluster/deploy-hasingleton-jboss-beans.xml file is deployed before jboss-web.sar. That will trigger activation of the deploy-hasingleton profile, and the war will not complete deployment pending dependency on jboss-web.sar. Not a problem, since at the end of the whole thing the dependency will be satisfied and the war will deploy. Except, the validate call during the deploy-hasingleton activation will throw an exception. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4204865#...
