| A Topic can be declared via xml in the `<tomee-home>/conf/tomee.xml` |
| file or in a `WEB-INF/resources.xml` file using a declaration like the |
| following. All properties in the element body are optional. |
| |
| [source,xml] |
| ---- |
| <Resource id="myTopic" type="javax.jms.Topic"> |
| destination = |
| </Resource> |
| ---- |
| |
| Alternatively, a Topic can be declared via properties in the |
| `<tomee-home>/conf/system.properties` file or via Java VirtualMachine |
| `-D` properties. The properties can also be used when embedding TomEE |
| via the `javax.ejb.embeddable.EJBContainer` API or `InitialContext` |
| |
| [source,properties] |
| ---- |
| myTopic = new://Resource?type=javax.jms.Topic |
| myTopic.destination = |
| ---- |
| |
| Properties and xml can be mixed. Properties will override the xml |
| allowing for easy configuration change without the need for $\{} style |
| variable substitution. Properties are not case sensitive. If a property |
| is specified that is not supported by the declared Topic a warning will |
| be logged. If a Topic is needed by the application and one is not |
| declared, TomEE will create one dynamically using default settings. |
| Multiple Topic declarations are allowed. # Supported Properties |
