30.4.4. High Availability JNDI (HA-JNDI)

download PDF
If you are using JNDI to look-up JMS queues, topics and connection factories from a cluster of servers, it is likely you will want to use HA-JNDI so that your JNDI look-ups will continue to work if one or more of the servers in the cluster fail.
HA-JNDI is a JBoss Application Server service which allows you to use JNDI from clients without them having to know the exact JNDI connection details of every server in the cluster. This service is only available if using a cluster of JBoss Application Server instances.
To use it use the following properties when connecting to JNDI.
Hashtable<String, String> 
  jndiParameters = new Hashtable<String, String>();
jndiParameters.put("java.naming.factory.initial", 
    "org.jnp.interfaces.NamingContextFactory");
jndiParameters.put("java.naming.factory.url.pkgs=", 
    "org.jboss.naming:org.jnp.interfaces");

initialContext = new InitialContext(jndiParameters);
For more information on using HA-JNDI see the Clustering section of the Administration and Configuration Guide for this release of JBoss Enterprise Application Platform.
