Hello, I am using JBoss 4.0.3SP1 and I am trying to find out what all happens when I set the CallByValue attribute of the NamingService MBean in the conf/jboss-service.xml file to true. Will that mean I am unmarshalling every single jndi call or are there only certain cases where it does? I am looking at turning this flag on in our production system, but I am concerned about the performance impact. Thanks, Matt View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4003520#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
