Sending and Receiving Messages with EAI MSMQ Transport

The following procedure describes how to set up your system to send a message to an external system using the EAI MSMQ Transport and receive a synchronous message back from the external system by the EAI MSMQ Transport.

To send a literal to MSMQ and receive a response

1. Access the Windows Computer Management tool by choosing the Start menu, Programs, Administrative Tools, and then Computer Management.

2. Set up an MSMQ queue to receive messages from the Siebel application, and give the queue an easily identified name, such as fromsiebel.

3. Set up another queue to send messages to the Siebel application, and give the queue an easily identified name, such as tosiebel.

4. Set up a workflow in Siebel Tools to send a message out and receive a message back in response using EAI MSMQ Transport. The workflow should contain the following steps, as shown in the following image:

   1. EAI Siebel Adapter (Query)

   2. EAI XML Converter (PropSet to XML)

   3. EAI MSMQ Transport (Send Receive)

   4. XML Converter (XML to PropSet)

   5. Siebel Adapter (Upsert)

   

   Note: For details on the Business Process Designer, see Siebel Business Process Framework: Workflow Guide.

5. Create the following process properties:

   Name	Data Type	In/Out
   Test Message	Hierarchy	In/Out
   Test XML	Binary	In/Out
   Error Code	String	In/Out
   Error Message	String	In/Out
   Object Id	String	In/Out
   Siebel Operation Object Id	String	In/Out

6. Set up the first step of the workflow after Start to use EAI Siebel Adapter with the Query method to query the information from the Siebel Database using the following input and output arguments:

   Input Argument	Type	Value	Property Name	Property Data Type
   OutputIntObjectName	Literal	Sample Employee	Not applicable	Not applicable
   PrimaryRowId	Process Property	Not applicable	Object Id	String

   Property Name	Type	Output Argument
   Test Message	Output Argument	SiebelMessage

7. Set up the second step to use the EAI XML Converter business service with the IntObjHierToXMLDoc method to convert the data extracted from the Siebel Database to XML format, using the following input and output arguments:

   Input Argument	Type	Property Name	Property Data Type
   SiebelMessage	Process Property	Test Message	Hierarchy

   Property Name	Type	Output Argument
   Test XML	Output Argument	<Value>

8. Set up the third step of the workflow, after Start, to use the EAI MSMQ Transport business service with the SendReceive method to receive the incoming XML message, using the following input and output arguments:

   Input Argument	Type	Value	Property Name	Property Data Type
   <Value>	Process Property	Not applicable	Test XML	Binary
   MsmqPhysicalQueueName	Literal	fromsiebel	Not applicable	Not applicable
   MsmqQueueMachineName	Literal	SiebelServer1 Computer name where the Siebel MSMQ Transport is running.	Not applicable	Not applicable
   MsmqRespQueueMachineName	Literal	SiebelServer2	Not applicable	Not applicable
   MsmqRespQueueName	Literal	tosiebel	Not applicable	Not applicable

   Property Name	Type	Output Argument
   Test XML	Output Argument	<Value>

9. Set up the fourth step to use the EAI XML Converter business service with the XMLDocToIntObjHier method to convert the XML message to a Siebel Message using the following input and output arguments:

   Input Argument	Type	Property Name	Property Data Type
   <Value>	Process Property	Test XML	Binary

   Property Name	Type	Output Argument
   Test Message	Output Argument	SiebelMessage

10. Set up the last step to use the EAI Siebel Adapter with the Upsert method to update the Siebel Database, using the following input argument:

    Input Argument	Type	Property Name	Property Data Type
    SiebelMessage	Process Property	Test Message	Hierarchy

11. Save the workflow and run a test using the Workflow Simulator.

    The output property set must have a message in the Value field. Additionally, the EndOfData argument in the property set must be set to True.

    Note: To test this scenario adequately, you must have a partner application that can accept the message and return a response. The correlation ID of the response message must be set to the message ID of the message originally sent by the Siebel application.
