You may notice a createInstance attribute in the initial receive activity. In this initial receive activity, the createInstance element is set to yes. This starts a new instance of the BPEL process service component. At least one instance startup is required for a conversation. For this reason, you set the createInstance variable to no in the second receive activity.

The following example shows the source code for the createInstance attribute:

    <!-- receive input from requester -->
    <receive name="receiveInput" partnerLink="client"
             portType="tns:LoanBroker"
             operation="initiate" variable="input"
             createInstance="yes"/>
