"Re: Snowdrop and JBoss AS 7.2.0" To view the discussion, visit: https://community.jboss.org/message/790006#790006 -------------------------------------------------------------- The reason of incompatibility Snowdrop subsystem with JBoss AS 7.2.0.Alpha1-SNAPSHOT is the fact ExtensionContext registerSubsystem methods have changed. Changes needed to make Snowdrop subsystem can be registered in JBoss AS 7.1.3 onwards are as follows: 1. In snowdrop-parent.pom change <version.org.jboss.as7>7.1.3.Final</version.org.jboss.as7> 2. amend org.jboss.spring.deployers.as7.SpringExtension class /* * JBoss, Home of Professional Open Source. * Copyright 2010, Red Hat, Inc., and individual contributors * as indicated by the @author tags.
