There are a performance problem with Seam, after migration from 1.1.x to 1.2. One of interceptors, ManagedEntityIdentityInterceptor, for each method call in my backing bean, was calling Transactions.isTransactionMarkedRollback(...), that was trying to lookup for a name (userTransactionName). On tomcat, where there are no JNDI server started, I see a lot of javax.naming.CommunicationException in my logs. It's not a funtional problem, but it's degrading my performance for nothing. There are any option to disable that feature, removing the interceptor or caching an information that the lookup is not working? javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused: connect]] at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:208) at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1092) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:470) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:463) at javax.naming.InitialContext.lookup(InitialContext.java:351) at org.jboss.seam.util.Transactions.getUserTransaction(Transactions.java:149) at org.jboss.seam.util.Transactions.isUTTransactionMarkedRollback(Transactions.java:140) at org.jboss.seam.util.Transactions.isTransactionMarkedRollback(Transactions.java:67) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4046284#...
