[jboss-user] [JBoss AOP] - Hotswapping an interceptor to an EJB

[Giordacchio++]

Hi !

I have a strange erroer when I try use hotswapping. I want to attach dinamically an interceptor to a method of an EJB.

I have prepared the class that I want to intercept with this tag in my jboss-aop.xml:


  | <prepare expr="all(it.webscience.atlasweb.controller.SessionManagerAction)"/>

But when I try to deploy my app I get this strange exception exactly on the EJB that I want to intercept!

Someone knows why the exception says that my EJB has two destroy method when actually it has only one ??

Thx ;-)
