The node name can be set by using '-Djboss.node.name' in standalone mode.
In domain mode this is not possible.

The attribute "name" of the server element should be used for that (for SA and domains host.xml)
But current there is no effect if the client use EJBClient.getUserTransaction( node-name ), client error is "No EJBReceiver available for node name
MyNode".
The management console shows the correct server name set by <server name=>.

Also if the system-properties element is used to set "jboss.node.name" this is not reflected by management console
but if an application use System.getProperty("jboss.node.name") the value of the system-property is returned.
