What about Scout 1.0rc1 it uses xml beans in multiple sources, not just IRegistry implementation: [/home/opalka][/home/opalka/THIRDPARTY/SCOUT/sources/tags]>grep -r "xmlbeans" * | grep -v "\.svn" | grep import v1.0rc1/scout/src/main/java/org/apache/ws/scout/registry/BusinessLifeCycleManagerImpl.java:import org.apache.xmlbeans.XmlObject; v1.0rc1/scout/src/main/java/org/apache/ws/scout/registry/RegistryImpl.java:import org.apache.xmlbeans.XmlCursor; v1.0rc1/scout/src/main/java/org/apache/ws/scout/registry/RegistryImpl.java:import org.apache.xmlbeans.XmlException; v1.0rc1/scout/src/main/java/org/apache/ws/scout/registry/RegistryImpl.java:import org.apache.xmlbeans.XmlObject; v1.0rc1/scout/src/main/java/org/apache/ws/scout/util/ScoutJaxrUddiHelper.java:import org.apache.xmlbeans.XmlObject; Thus it's not just about replacing the IRegistry implementation. Also ScoutJaxrUddiHelper is heavily reused in scout and there's no JVM property for replacing it with custom impl:( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4195238#...
