Sending and Receiving Messages with the EAI HTTP Transport

You can use the EAI HTTP Transport to send and receive messages. The following procedure illustrates how you can use EAI HTTP Transport with the SendReceive method to query employee information from the Siebel Database, send it out, echo it using the Workflow Utilities ECHO service, and send it back to the workflow to write the response back to a file.

To create a workflow to send and receive messages

1. Create a named subsystem HTTPsendreceive_conn for subsystem HTTPSubSys using the following lines:

   HTTPLoginMethod=GET
   
   HTTPLoginURLTemplate="http://websrvr.example.com:16007/myapplication/
   login.jsp?usr=V1&psw=v2"
   
   HTTPLogoffMethod=GET
   
   HTTPLogoffURLTemplate="http://websrvr.example.com:16007/myapplication/
   logoff.jsp"
   
   HTTPRequestMethod=POST
   
   HTTPRequestURLTemplate="http://websrvr.example.com:16007/myapplication/
   data.jsp"
   

2. Create a named subsystem MyEchoSubsys for subsystem EAITransportDataHandlingSubsys using the following lines:

   DispatchService="Workflow Utilities"
   DispatchMethod=ECHO
   

3. In your eai.cfg file, add the following line in the [HTTP Services] section:

   MyEcho = MyEchoSubsys
   

4. Set up a new workflow in Siebel Tools containing the following steps, as shown in the following image:

   1. Get Employee

   2. Convert to XML

   3. Send and Receive

   4. Write to File

   

   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
   Employee Message	Hierarchy	In/Out
   Employee XML	Binary	In/Out
   Error Code	String	In/Out
   Error Message	String	In/Out
   Object Id	String	In/Out
   Response	Binary	In/Out

6. Retrieve the employee message using the EAI Siebel Adapter with the Query method to query the information from the 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
   Employee Message	Output Argument	SiebelMessage

7. Convert the message to XML using the EAI XML Converter with the Integration Object Hierarchy to XML Document method and the following input and output arguments to convert the message.

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

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

8. Send and receive the converted XML message using the EAI HTTP Transport with the Send and Receive Response method and the following input and output arguments.

   Input Argument	Type	Value	Property Name	Property Data Type
   <Value>	Process Property	Not applicable	Employee XML	String
   ConnectionSubsystem	Literal	HTTPsendreceive_conn	Not applicable	Not applicable

   Property Name	Type	Output Argument
   Response	Output Argument	<Value>

9. Write the message to the file using the EAI File Transport with the Send method and the following input arguments.

   Input Argument	Type	Value	Property Name	Property Data Type
   <Value>	Process Property	Not applicable	Response	Binary
   FileName	Literal	C:\SendRec.txt	Not applicable	Not applicable

10. Save your workflow and test it using the Workflow Simulator.
