Ah, in that case: public abstract class MyEntityQuery extends EntityQuery { | | // Overridden/extra methods | } <component name="fooQuery" class="MyEntityQuery"> | <property name="maxResults">10</maxResults> | <component> - you loose the namespace stuff in components.xml. You could always set up your own namespace for MyEntityQuery if you like. HTH View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044253#...
