The first thing you can do is confirm that you've bound the entry into HA-JNDI. If you access the JNDIView mbean from the JMX Console, you can invoke the List method and see if the entry is bound into the HA-JNDI namespace. If it's there, then it should also be bound on your other server. If instead, the entry is bound into the Global JNDI Namespace, it would only be accessible from the other server if you used an HA-JNDI server to perform the lookup. Since you didn't specify a HA-JNDI server in your context, you would need to use auto discovery to accomplish this.
