Examples of org.hornetq.api.core.client.ServerLocator

org.hornetq.api.core.client.ServerLocator
The serverLocator locates a server, but beyond that it locates a server based on a list.
If you are using straight TCP on the configuration, and if you configure your serverLocator to be HA, the locator will always get an updated list of members to the server, the server will send the updated list to the client.
If you use UDP or JGroups (exclusively JGropus or UDP), the initial discovery is done by the grouping finder, after the initial connection is made the server will always send updates to the client. But the listeners will listen for updates on grouping. @author Tim Fox
