Thanks for the quick response, Actually I'm starting the EJB container using EJB3StandaloneBootstrap.boot(); Then I have a EJB3StandaloneDeployer deploy the EJBs. Seam doesn't start the EJB container, but because my EJB package contains the ejb-jar.xml file, the SeamInterceptor gets installed before Seam is initialized. What I'd like to do is to deploy the EJBs in the container without installing the SeamInterceptor, access the EJBs and install the SeamInterceptor just before deploying my webapp (which will initialize Seam). In other words, I'd like to "upgrade" my EJBs to Seam components right before starting Seam. What I don't know is: Is there a way to install the SeamInterceptor in the EJB container (or in the JBoss Micro Container) after it has been started and before Seam gets initialized (or maybe it doesn't matter if the SeamInterceptor is installed after Seam initialization) ?
