The source code in the following example provides details about the subscribed event of the Oracle Mediator service component.

<component name="OrderPendingEvent">
    <implementation.mediator src="OrderPendingEvent.mplan"/>
    <business-events>
      <subscribe
         xmlns:sub1="/oracle/fodemo/storefront/entities/events/edl/OrderEO"
         name="sub1:NewOrderSubmitted" consistency="oneAndOnlyOne"
         durable="true" runAsRoles="$publisher"/>
</business-events>
</component>

While not explicitly demonstrated in this example, you can define XPath filters on events. In the following example, the event is accepted for delivery only if the initial deposit is greater than 50000:

    <business-events>
        . . .
        . . .
        <filter>
            <xpath xmlns:be="http://oracle.com/fabric/businessEvent"
                 xmlns:ns1="http://xmlns.oracle.com/singleString"
                   <xpath expression= "/be:business-event/be:content/
                   sub1:AccountInfo/Details[@initialDeposit > 50000]" />
        </filter>
      . . .
      . . .
    </business-events>
