You can define these in Tomcat by using <Resource /> tags. Again, see the link I sent previously. > Is it possible to use and external independent Naming Service, such as LDAP to > store JMS Admin objects in conjunction with Tomcat? You can connect to an LDAP server, but that has nothing to do with Tomcat. You'd just use the functionality present in the JVM. > The whole idea of > having a Naming Service was to separate objects.

There is no url, server or port required when loading items from JNDI with Tomcat. See the links I previously sent which show how to grab objects from JNDI. > Does Tomcat have a Naming Service running inside it which stores the admin > objects? Yes, it has naming service, but I'm not sure what you mean by "admin objects". Anything you configure with Resource tags will be available to your applications through JNDI. If you don't configure it, it won't be available. > If so, is it accessible via a URL? Yes. Resources are located in JNDI with the URL "java:comp/env/...". The rest of the path depends on what you setup in your Resource tag.
