So, for Weld we use an interceptor in order to apply the JSR-299 interceptors (bound using @InterceptorBinding) to EJBs.

The requirement is to invoke those interceptors after the standard EJB 3 interceptors. In order to do that, we try to place the additional interceptor last in the list.

http://anonsvn.jboss.org/repos/jbossas/trunk/weld-int/deployer/src/main/java/org/jboss/weld/integration/deployer/metadata/WeldEjbInterceptorMetadataDeployer.java

The line that is supposed to do this is:

{code}

      // Add JSR-299 binding interceptor as the last (all others have to be
      // called first)
      interceptorBindings.add(bindingsIBMD);
 
{code}
