5.2.6. Interception
To perform actions such as bijection, context demarcation, and validation, Seam must intercept component invocations. For JavaBeans, Seam controls component instantiation completely, and no special configuration is required. For entity beans, interception is not required, since bijection and context demarcation are not defined. For session beans, an EJB interceptor must be registered for the session bean component. This can be done with an annotation, as follows:
@Stateless @Interceptors(SeamInterceptor.class) public class LoginAction implements Login { ... }
@Stateless
@Interceptors(SeamInterceptor.class)
public class LoginAction implements Login { ... }
However, it is better to define the interceptor in
ejb-jar.xml
