Intercepting Home-Interfaces

[pilhuhn]

Hi,
is it possible to intercept calls to home interfaces with JBossAOP? With the old interceptors, this is fairly easy.

Things that I am thinking of are e.g. measure the timing of entity-Finders.

No, it is not possible with JBoss AOP. The reason? It is because there is no class to massage...Our EJB implementation does not generate any class that implements the home interface. If you implemented BMP customer finders or home methods on the bean class, then yes, JBoss AOP could be used.

Do I understand it correctly, that the HomeInterface is implemented by a proxy? If so, would a $implements (like the $instanceof one) help to do something like

pointcut="call($implements(javax.ejb.EntityHome->findBy*(..)) ?

I think a $implements expression would be nice anyway. :-)

No, that is incorrect. Nothing implements the home interface (not even customer finders and home methods) The EJB container handles home invocations dynamically or these methods are implemented in methods on the Bean class as ejbFindMETHOD or ejbHomeMETHOD methods.
