Regarding 3) What would this xsd:refine map to in jaxb annotations? My understanding was that using jaxb it generates a schema from the annotations? | It doesn't map to anything . The xsd:redefine, just specifies what is the default behaviour the JBossXBBuilder which is to include types reachable from your hierarchy in your namespace (absent any explicit namepace= in the annotations). anonymous wrote : | Apart from that, if I have understood you correctly, mc-commons.xsd would contain the current bean_deployer_2_0.xsd. | Yes, except the root elements (deployment, bean, etc.) and without a namspace anonymous wrote : | I would then be able to do | | | <aop> | | <bean name="Bean" class="Foo"/> | | <aspect class="MyAspect" scope="PER_VM"> | | <property name="thing">XXX</property> | | </aspect> | | </aop> | | | Correct anonymous wrote : | If I wanted to do this the other way around, I would need to use xmlns on the aop specific elements | | | <deployment> | | <bean name="Bean" class="Foo"/> | | <aspect xmlns:aop="urn:jboss:aop-beans:1.0" class="MyAspect" scope="PER_VM"> | | <property name="thing">XXX</property> | | </aspect> | | </deployment> | | | | I'm not sure what the xmlns should be for property, but apart from that is my understanding correct? The idea is you don't need one. What you defined is probably not correct unless your schema allows urn:jboss:bean-deployer:2.0:property as an element of aspect. The correct usage would be either explicit | <deployment> | <bean name="Bean" class="Foo"/> | <aspect xmlns:aop="urn:jboss:aop-beans:1.0" class="MyAspect" scope="PER_VM"> | <aop:property name="thing">XXX</aop:property> | </aspect> | </deployment> | or change the default namespace | <deployment> | <bean name="Bean" class="Foo"/> | <!-- HERE - simple xmlns --> | <aspect xmlns="urn:jboss:aop-beans:1.0" class="MyAspect" scope="PER_VM"> | <property name="thing">XXX</property> | </aspect> | </deployment> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4134250#...
