When a JMS client connects to the EI Message Broker, the connection parameters are specified using the connectionfactory interface as shown below.

...

• <transport>: The transport should be TCP.

  Info
  To support more transports, the ''client.transportTransportConnection'' class needs to be updated along with the parsing to handle the transport.

• <host>: The IP address.
• <port>: The default AMQP port of 5672 is used if no port is specified.

• <option>='<value>': Each broker can have additional options that are specific to that broker. The following are the options that are currently implemented:

  Option	Default Value	Description
  retries	1	The number of retry attempts when connecting to the broker.
  ssl	false	Use SSL on the connection.
  connecttimeout	30000	How long (in milliseconds) to wait for the connection to succeed.
  connectdelay	none	How long (in milliseconds) to wait before attempting to reconnect. The recommended value is 30000 milliseconds.

Using the 'failover' option

...

• <method>: Listed below are the supported methods. Note that 'singlebroker' is used when only one broker is present and the 'roundrobin' method is used with multiple brokers. The 'nofailover' method is useful if you are using a 3rd party tool that has its own reconnection strategy that you wish to use.

  Method	Description
  singlebroker	This will only use the first broker in the list.
  roundrobin	This method tries each broker in turn.
  nofailover	[New in 0.5] This method disables all retry and failover logic.
  onetime	This method ensures that a connection of XA transactions does not failover. See Handling Distributed Transactions for more information

  Note
  The <method> value in the URL may also be any valid class on the classpath that implements the FailoverMethod interface.

• <option>: The following options should be used for the failover method.

  Option	Default Value	Description
  cyclecount	1	The number of times to loop through the list of available brokers before failure.
