Correct, if you deploy an EJB 3 bean it constructs an EJB container without weaving. The configuration for these containers is in ejb3-interceptors-aop.xml. Calls to the ejb are done via the container and go through the stack of interceptors before hitting the ejb.


For example, if you deploy a stateless session bean it will use the 

  | <domain name="Stateless Bean" extends="Intercepted Bean" inheritBindings="true">
  | 

which uses pointcuts to apply the different interceptors that make up the container. e.g. the 

  |        <interceptor-ref name="org.jboss.ejb3.tx.CMTTxInterceptorFactory"/>
  | 
looks for the TransactionAttribute annotations on the different methods and applies the correct transactions.

You can either add to these domains in ejb3-interceptors-aop.xml in which case it will apply to all beans matching your pointcuts, or you can create a custom domain with more bindings and choose to apply it to a particular bean using the @AspectDomain annotation

http://www.jboss.org/ejb3/docs/tutorial/configuration/configuration.html
explains more about this. You can get there by going to http://www.jboss.org/community/wiki/EJB3 and then 'Tutorial' and then 'Custom configuration'
