Just for your information, the above problem occurs with this configuration app/deploy/mywebapp.war app/deploy/app_aspect.aop app/deploy/app_aspect/META-INF/jboss-aop.xml I also tried to deploy the aspect using the other scheme: app/deploy/mywebapp.war app/deploy/app_aspect.jar <- this contains the interceptor app/deploy/app_aspect-aop.xml That provokes the same error. I tried to put app_aspect.aop inside mywebapp.war (as stated somewhere in the docs) but the aspect seems to not get deployed.
