| <p>The static transport provides a hard coded mechanism to discover other connections using a list of URIs. A connection using this discovery mechanism will attempt to connect to all URIs in the list until it is succesful.</p> |

| |
| <p>As the static transport protocol is for broker discovery, it should not be used by client programs. Clients wishing to failover to a static list of broker instances, should use the <a shape="rect" class="external-link" href="http://activemq.apache.org/failover-transport-reference.html">failover://</a> transport instead. </p></div> |
