Friends,

I have a design issue. Can you please help me in this regard.
I have a request like this:
<?xml version="1.0" encoding="UTF-8"?>
<msg xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Request.xsd">
<header>
<SchemaVersion>Text</SchemaVersion>
<Action>Purchase</Action>
<OrigSystemID>aaaaaaaaaaaaaa</OrigSystemID>
<TransactionPrioirty>Text</TransactionPrioirty>
<EchoBack>Text</EchoBack>
<TransactionID>Text</TransactionID>
</header>
<body>
<Request>
<PurchaserID>Text</PurchaserID>
<MACAddress>Text</MACAddress>
<EventID>Text</EventID>
<Title>Text</Title>
</Request>
</body>
</msg>

Once this request comes, i need to do a service orchestration which does the following
1.Retrieve AccID
2.Add a work Order
3.Retrieve the MAC address
4. Aggregate and respond.

For acheiveing this sort of workflow in Spring, should I use a OSWorkflow Engine?

Any help is appreciated.

Thanks.
