No its an incallback.


  |     <bean name="UserTransactionRegistry" class="org.jboss.tm.usertx.UserTransactionRegistry">
  | 
  | THIS REGISTERS ALL USER TRANSACTION PROVIDERS
  | 
  |       <!-- Register providers -->
  |       <incallback method="addProvider"/>
  |       <uncallback method="removeProvider"/>
  | 
  | THIS REGISTERS THE LISTENERS (Currently only the CCM)
  | 
  |       <!-- Register listeners -->
  |       <incallback method="addListener"/>
  |       <uncallback method="removeListener"/>
  |     </bean>
  | 

That way you can remove the ejb and jca configs without having to redo
the other configurations.
