  |

  | <domain name="Stateful Bean" extends="Base Stateful Bean" inheritBindings="true">
  | ...
  |       <annotation expr="!class(@org.jboss.annotation.ejb.cache.simple.CacheConfig) AND !class(@org.jboss.annotation.ejb.Clus
  | tered)">
  |          @org.jboss.annotation.ejb.cache.simple.CacheConfig (maxSize=100000, idleTimeoutSeconds=3600
  | )
  |       </annotation>
  | ...
  |    </domain>	
  | [/code ]
