You'vre done well on your hunt. :-) Be aware, though, that you might have problems if you have a transaction running and you make an EJB call that ends up going to the in-VM bean. The TxPropagationInterceptor will not handle this well if the (Clustered)IsLocalInterceptor is bypassed. See http://jira.jboss.com/jira/browse/EJBTHREE-1005. This will only be a problem for you if your servlet initiates transactions or your beans make calls from one to another within a tx.
