| |
| A MessageDrivenContainer 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] |
| ---- |
| <Container id="myMessageDrivenContainer" type="MESSAGE"> |
| activationSpecClass = org.apache.activemq.ra.ActiveMQActivationSpec |
| instanceLimit = 10 |
| messageListenerInterface = javax.jms.MessageListener |
| resourceAdapter = Default JMS Resource Adapter |
| </Container> |
| ---- |
| |
| Alternatively, a MessageDrivenContainer 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] |
| ---- |
| myMessageDrivenContainer = new://Container?type=MESSAGE |
| myMessageDrivenContainer.activationSpecClass = org.apache.activemq.ra.ActiveMQActivationSpec |
| myMessageDrivenContainer.instanceLimit = 10 |
| myMessageDrivenContainer.messageListenerInterface = javax.jms.MessageListener |
| myMessageDrivenContainer.resourceAdapter = Default JMS Resource Adapter |
| ---- |
| |
| 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 |
| MessageDrivenContainer a warning will be logged. If a |
| MessageDrivenContainer is needed by the application and one is not |
| declared, TomEE will create one dynamically using default settings. |
| Multiple MessageDrivenContainer declarations are allowed. # Supported |
