 * An application may use this annotation to specify a Jakarta Messaging {@code

 * used at the application's deployment to provision the required resource and allows an application to be deployed into
 * a Jakarta EE environment with more minimal administrative configuration.
 * 
 * The {@code ConnectionFactory} resource may be configured by setting the annotation elements for commonly used
 * properties. Additional properties may be specified using the {@code properties} element. Once defined, a
 * {@code ConnectionFactory} resource may be referenced by a component in the same way as any other
 * {@code ConnectionFactory} resource, for example by using the {@code lookup} element of the {@code Resource}
 * annotation.
