232 Using IBM WebSphere Message Broker as an ESB with WebSphere Process Server
8.3 Queue manager implementation of WebSphere MQ
WebSphere Message Broker requires a queue manager. For this scenario, the
following queues must be defined on the broker’s queue manager using the
default options. Keep in mind that queue names are case-sensitive.

򐂰 SC4.FINDSUPPLIERS.WS.RESPONSE.IN

򐂰 SC4.REQUEST.SUPPLIER2.IN
8.4 Business integration module
In this section, we focus on the implementation of the business integration
module. The process receives a request that contains an item number as a
string. It sends the message to a WebSphere Message Broker message flow.
The message flow sends the message to multiple suppliers to see if the item is in
stock. The message flow compiles a list of supplier responses and sends the list
back to the requestor.
8.4.1 Business integration module components
The business process is implemented in a business integration module called
ProcessOrder. Figure 8-2 illustrates the assembly diagram for the ProcessOrder
module.
