　ofbiz 中使用xpdl定义工作流，所以要看定义语言，另外，ofbiz中的order模块是通过工作流实现的，此流程，首先在网上下订单，然后内部进行处理。 order例子的运行过程processorder--]checkblacklist --]processpayment --]success --] clearchart --] initiateOrderWorkflow --]start the workflow 1.首先根据订单提交时的用processorder，根据ecommerce下的controller.xml发现[request-map uri="processorder"][security https="true"/][event type="java" path="org.ofbiz.commonapp.order.shoppingcart.CheckOutEvents" invoke="createOrder"/][response name="success" type="request" value="checkBlacklist"/][response name="error" type="view" value="checkout"/][/request-map]在调用createOrder成功后，根据success的条件，调用checkBlacklist，同样在根据ecommerce下的controller.xml发现 [request-map uri="checkBlacklist"][security direct-request="false"/][event type="java" path="org.ofbiz.commonapp.order.shoppingcart.CheckOutEvents" invoke="checkOrderBlacklist"/][response name="success" type="request" value="processpayment"/][response name="failed" type="request" value="failedBlacklist"/][response name="error" type="view" value="checkout"/][/request-map] 在checkOrderBlacklist成功后，根据success，转向processpayment[request-map uri="processpayment"][security https="true" direct-request="false"/][event type="java" path="org.ofbiz.commonapp.order.shoppingcart.CheckOutEvents" invoke="processPayment"/][response name="success" type="request" value="clearcartfororder"/][response name="fail" type="view" value="checkoutoptions"/][response name="error" type="view" value="checkout"/][/request-map] processPayment成功后，转向clearcartfororder[request-map uri="clearcartfororder"][security direct-request="false"/][event type="java" path="org.ofbiz.commonapp.order.shoppingcart.ShoppingCartEvents" invoke="clearCart"/][response name="success" type="request" value="initiateOrderWorkflow"/][response name="error" type="view" value="checkout"/][/request-map] 成功后，调用initiateOrderWorkflow，[request-map uri="initiateOrderWorkflow"][security https="true" direct-request="false"/][event type="java" path="org.ofbiz.commonapp.order.shoppingcart.CheckOutEvents" invoke="initiateOrderWorkflow"/][response name="success" type="request" value="checkExternalPayment"/][response name="error" type="view" value="checkout"/][/request-map] 在initiateOrderWorkflow中， dispatcher.runAsync("processOrder", UtilMisc.toMap("orderId", orderId, "orderStatusId", orderHeader.getString("statusId")));启动工作流，对应services_order.xml中的[service name="processOrder" engine="workflow" location="org.ofbiz.commonapp.order.order" invoke="ProcessOrder"][description]Service for testing the workflow engine[/description][attribute name="orderId" type="String" mode="IN" optional="false"/] [attribute name="orderStatusId" type="String" mode="INOUT" optional="false"/][/service]此service的engine为workflow表示是一个工作流的服务， service的定义ProcessOrder中的location表示xpdl定义中的package，[Package Id="org.ofbiz.commonapp.order.order"]invoke对应与在orderProcessXPDL.xml中，[WorkflowProcess Id="ProcessOrder" Name="Processes incoming orders"]
