| <div class="wiki-content maincontent"><h2>Configuring NMS.Stomp</h2> |
| |
| <p>All configuration is achieved via URI-encoded parameters, either on the connection or destinations. Through the URIs, you can configure virtually every facet of your NMS.Stomp client. The tables below show the comprehensive set of parameters.</p> |
| |
| <h3><strong>Connection URI Parameters</strong></h3> |
| |
| |
| <h5> Example Configuration</h5> |
| |
| <p>Using the Generic NMSConnectionFactory class would look as follows:</p> |
| |
| <structured-macro ac:macro-id="7e46419e-1c01-4a8a-bbe5-d30cb88303c8" ac:name="noformat" ac:schema-version="1"><plain-text-body> |
| var cf = new NMSConnectionFactory( |
| "stomp:tcp://localhost:61613"); |
| </plain-text-body></structured-macro> |
| |
| <p>You can also use the Stomp ConecctionFactory implementation directory:</p> |
| |
| <structured-macro ac:macro-id="c3b5e7f5-7d2d-4617-bb72-0dfe2557f130" ac:name="noformat" ac:schema-version="1"><plain-text-body> |
| var cf = new Apache.NMS.Stomp.ConnectionFactory( |
| "tcp://localhost:61613"); |
| </plain-text-body></structured-macro> |
| |
| <h3>Protocol Options</h3> |
| |
| <table><tbody><tr><th colspan="1" rowspan="1"><p> Option Name <br clear="none" class="atl-forced-newline"> </p></th><th colspan="1" rowspan="1"><p> Description </p></th></tr><tr><td colspan="1" rowspan="1"><p> tcp </p></td><td colspan="1" rowspan="1"><p> Uses TCP/IP Sockets to connect to the Broker. </p></td></tr><tr><td colspan="1" rowspan="1"><p> ssl </p></td><td colspan="1" rowspan="1"><p> Uses TCP/IP Sockets to connect to the Broker with an added SSL layer (Not available on .NETCF). </p></td></tr><tr><td colspan="1" rowspan="1"><p> failover </p></td><td colspan="1" rowspan="1"><p> Uses the Failover Transport to connect and reconnect to one or more Brokers </p></td></tr></tbody></table> |
| |
| |
| <p>You can add the failover option using the Generic NMSConnectionFactory class like this:</p> |
| |
| <structured-macro ac:macro-id="32e8292d-4333-4ec7-a147-52ab3460a9e6" ac:name="noformat" ac:schema-version="1"><plain-text-body> |
| var cf = new NMSConnectionFactory( |
| "stomp:failover:tcp://localhost:61613"); |
| </plain-text-body></structured-macro> |
| |
| <p>You can also use the Stomp ConecctionFactory implementation directory:</p> |
| |
| <structured-macro ac:macro-id="d2c17a8e-d03d-4b02-bbd3-850324c29e1d" ac:name="noformat" ac:schema-version="1"><plain-text-body> |
| var cf = new Apache.NMS.Stomp.ConnectionFactory( |
| "failover:tcp://localhost:61613"); |
| </plain-text-body></structured-macro> |

| <h5>Failover Transport Options</h5> |
| |
| <p>Prior to NMS.Stomp v1.4.0 the failover transport options did not use the transport.* prefix.</p> |
