This project is meant as a support for the A4M36ISS course. It servers as a simulation of three enterprise systems that will be integrated during course exercises.

How to run

mvn clean camel:run

Supported system properties

Name Default Description
broker.port 61617 Port on which external JBoss A-MQ is located to access Shipment system

Inventory

Input

  • CSV file placed in target/inbox/inventory.
  • File structure articleId;amount

Output

  • CSV file placed in target/outbox/inventory.
  • File structure articleId;amountReserved;amountLeft

Behaviour

At the startup the inventory is initiated with articles with ids 1..10 and amount that is the triple of id so 15 pices for article with id 5.

If there is enough pieces of a given article than the appropriate amount is reserved and the number of pices left is reduced and reported back. If there is not enough pieces the nothing is reserved and the current amount in inventory is reported.

Accounting

Input

  • Endpoint exposed at https://localhost:7070/accounting, using POST method
  • Certificate located at src/main/resources/keystore.jks
  • Client side SSL authentication is required
  • Credentials admin/foo
  • Example of JSON message
{
	"id": 1,
	"address": {
		"firstName": "Jiri",
		"lastName": "Novak",
		"street": "Purkynova",
		"city": "Brno",
		"zipCode": "602 00"
	},
	"items": [
		{
			"articleId": 10,
			"count": 30,
			"unitPrice": 3
		}
	]
}

Output

  • Example of JSON message
{
   "invoiceId": 1000001,
   "order":    {
      "id": 1,
      "items": [      {
         "articleId": 10,
         "count": 30,
         "unitPrice": 3
      }],
      "address":       {
         "firstName": "Jiri",
         "lastName": "Novak",
         "street": "Purkynova",
         "city": "Brno",
         "zipCode": "602 00"
      }
   },
   "status": "ISSUED"
}

Behaviour

Accounting either issues invoices (status ISSUED) and assigns invoice id as order id incremented by one million. If the total order price is either zero or less or over 1000 then it rejects invoce (status INVALID) and sets invoice id to -1.

Shipment

Input

  • JBoss A-MQ broker running at localhost:${broker.port} using openwire+ssl protocol
  • Certificate located at src/main/resources/keystore.jks
  • Credentials shipuser/shippwd
  • Queue SHPMNT.REQ
  • order id is stored in orderID JMS header
  • Payload is XML sent as a JMS text message, an example
<address>
	<firstName>Jiri</firstName>
	<lastName>Novak</lastName>
	<street>Purkynova</street>
	<city>Brno</city>
	<zipCode>602 00</zipCode>
</address>

Output

  • Queue SHPMNT.RESP
  • order id is stored in orderID JMS header
  • Payload is XML sent as a JMS text message, an example
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<delivery status="OK"/>

Behaviour

If city is set to Gotham then status returned is FAIL otherwise it is OK.
