ok, I have noticed on one page about clustering, the following statement: "Note You cannot currently use a non-JNP JNDI implementation (i.e. LDAP) for your local JNDI implementation if you want to use HA-JNDI. However, you can use JNDI federation using the ExternalContext MBean to bind non-JBoss JNDI trees into the JBoss JNDI namespace. Furthermore, nothing prevents you though of using one centralized JNDI server for your whole cluster and scrapping HA-JNDI and JNP." The last sentence is interesting... "one cetralized JNDI server"... anyone know how? Tanked..... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958544#...
