Class HornetQClient

java.lang.Object

org.hornetq.api.core.client.HornetQClient

public class HornetQClient
extends Object

Utility class for creating HornetQ ClientSessionFactory objects. Once a ClientSessionFactory has been created, it can be further configured using its setter methods before creating the sessions. Once a session is created, the factory can no longer be modified (its setter methods will throw a IllegalStateException.

Method Detail

createServerLocatorWithoutHA

public static ServerLocator createServerLocatorWithoutHA(TransportConfiguration... transportConfigurations)

Create a ServerLocator which creates session factories using a static list of transportConfigurations, the ServerLocator is not updated automatically as the cluster topology changes, and no HA backup information is propagated to the client

Parameters:

transportConfigurations -

Returns:

the ServerLocator

createServerLocator

public static ServerLocator createServerLocator(boolean ha,
                                TransportConfiguration... transportConfigurations)

Create a ServerLocator which creates session factories using a static list of transportConfigurations, the ServerLocator is not updated automatically as the cluster topology changes, and no HA backup information is propagated to the client

Parameters:

transportConfigurations -

Returns:

the ServerLocator

createServerLocatorWithoutHA

public static ServerLocator createServerLocatorWithoutHA(DiscoveryGroupConfiguration groupConfiguration)

Create a ServerLocator which creates session factories from a set of live servers, no HA backup information is propagated to the client The UDP address and port are used to listen for live servers in the cluster

Parameters:

discoveryAddress - The UDP group address to listen for updates

discoveryPort - the UDP port to listen for updates

Returns:

the ServerLocator

createServerLocator

public static ServerLocator createServerLocator(boolean ha,
                                DiscoveryGroupConfiguration groupConfiguration)

Create a ServerLocator which creates session factories from a set of live servers, no HA backup information is propagated to the client The UDP address and port are used to listen for live servers in the cluster

Parameters:

discoveryAddress - The UDP group address to listen for updates

discoveryPort - the UDP port to listen for updates

Returns:

the ServerLocator

createServerLocatorWithHA

public static ServerLocator createServerLocatorWithHA(TransportConfiguration... initialServers)

Create a ServerLocator which will receive cluster topology updates from the cluster as servers leave or join and new backups are appointed or removed. The initial list of servers supplied in this method is simply to make an initial connection to the cluster, once that connection is made, up to date cluster topology information is downloaded and automatically updated whenever the cluster topology changes. If the topology includes backup servers that information is also propagated to the client so that it can know which server to failover onto in case of live server failure.

Parameters:

initialServers - The initial set of servers used to make a connection to the cluster. Each one is tried in turn until a successful connection is made. Once a connection is made, the cluster topology is downloaded and the rest of the list is ignored.

Returns:

the ServerLocator

createServerLocatorWithHA

public static ServerLocator createServerLocatorWithHA(DiscoveryGroupConfiguration groupConfiguration)

Create a ServerLocator which will receive cluster topology updates from the cluster as servers leave or join and new backups are appointed or removed. The discoveryAddress and discoveryPort parameters in this method are used to listen for UDP broadcasts which contain connection information for members of the cluster. The broadcasted connection information is simply used to make an initial connection to the cluster, once that connection is made, up to date cluster topology information is downloaded and automatically updated whenever the cluster topology changes. If the topology includes backup servers that information is also propagated to the client so that it can know which server to failover onto in case of live server failure.

Parameters:

discoveryAddress - The UDP group address to listen for updates

discoveryPort - the UDP port to listen for updates

Returns:

the ServerLocator
