S stands for Simple and Standard and Springless. Also camel-jms was already taken. ![(smile)](/confluence/s/34gb19/8804/10mvnxf/_/images/icons/emoticons/smile.svg) |

URI format
Code Block |

{code}
h3. URI format
{code}
sjms:[queue:|topic:]destinationName[?options]
{code}
Where {{destinationName}} is a JMS queue or topic name. By default, the {{destinationName}} is interpreted as a queue name. For example, to connect to the queue, {{FOO.BAR}} use: |
...
{code |
}
sjms:FOO.BAR
{code}
You can include the optional {{queue:}} prefix, if you prefer: |
...
{code |
}
sjms:queue:FOO.BAR
{code}
To connect to a topic, you _must_ include the {{topic:}} prefix. For example, to connect to the topic, {{Stocks.Prices}}, use: |
...
{code |
}
sjms:topic:Stocks.Prices
{code}
You append query options to the URI using the following format, {{?option=value&option=value&...}}

SjmsComponent Options and Configurations |
...
Below is an example of how to configure the SjmsComponent with its required ConnectionFactory provider. It will create a single connection by default and store it using the components internal pooling APIs to ensure that it is able to service Session creation requests in a thread safe manner. |
...
{code |
}
SjmsComponent component = new SjmsComponent();
component.setConnectionFactory(new ActiveMQConnectionFactory("tcp://localhost:61616"));
getContext().addComponent("sjms", component);
{code}
For a SjmsComponent that is required to support a durable subscription, you can override the default ConnectionFactoryResource instance and set the *clientId* property. |
...
{code |
}
ConnectionFactoryResource connectionResource = new ConnectionFactoryResource();
connectionResource.setConnectionFactory(new ActiveMQConnectionFactory("tcp://localhost:61616"));
connectionResource.setClientId("myclient-id");
SjmsComponent component = new SjmsComponent();
component.setConnectionResource(connectionResource);
component.setMaxConnections(1);
