Creating the WebService message flows

The WSRR WebService message flows are supplied, but if you prefer to create the message flows yourself, follow the instructions below:

1. In the Message Brokers Toolkit, switch to the Broker Application Development perspective.
2. Create a new message flow project called WSRR Connectivity Message Flows. Add a project dependency to the WSRR Connectivity Message Set project.
   For instructions, see Creating a message flow project [TODO: FIX THIS LINK].
3. Create a new message flow called DemoCustomer_WebService_v10.
   For instructions, see Creating a message flow. [TODO: FIX THIS LINK]
4. In the Message Flow editor, add and rename the nodes listed in the following table.
   For instructions, see Adding a node. [TODO: FIX THIS LINK]

   Palette drawers	Node type	Node name
   Web Services	SOAPInput	SOAP DemoCustomer
   Transformation	Compute	Create WS Response
   Web Services	SOAPReply	SOAP Reply

5. Connect the nodes together as listed in the following table.
   For instructions, see Connecting nodes. [TODO: FIX THIS LINK]
   To check that you have connected the nodes together correctly, see the figure in About the WSRR Connectivity sample.

   Node name	Terminal	Connect to this node
   SOAP DemoCustomer	Out	Create WS Response
   Create WS Response	Out	SOAP Reply

6. Configure the node properties as listed in the following table. Accept the default values for all properties unless an alternative value is listed in the table.
   For instructions, see Configuring a node. [TODO: FIX THIS LINK]

   Node name	Page	Property	Value
   SOAP DemoCustomer	Basic	WSDL file name	Browse to the DemoCustomer_v10.wsdl file imported earlier into the WSRR Connectivity Message Set. Once selected, this will populate the other properties on the Basic page.

7. Double-click the Create WS Response node to open the ESQL editor. Copy and paste the following ESQL code modules to the ESQL file. For more information, see Developing ESQL. [TODO: FIX THIS LINK]

   DECLARE tns NAMESPACE 'http://schemas.xmlsoap.org/soap/envelope/';
   DECLARE intf NAMESPACE 'http://demo.sr.eis.ibm.com';
   
   CREATE COMPUTE MODULE DemoCustomer_WebService_v10_CreateWSResponse
     CREATE FUNCTION Main() RETURNS BOOLEAN
     BEGIN
       CALL CopyMessageHeaders();
       SET OutputRoot.SOAP.Body.intf:updateCustomerResponse.updateCustomerReturn = 'Updated Customer via WebService version 1.0';
       RETURN TRUE;
     END;
     
     CREATE PROCEDURE CopyMessageHeaders() BEGIN
       DECLARE I INTEGER;
       DECLARE J INTEGER;
       SET I = 1;
       SET J = CARDINALITY(InputRoot.*[]);
       WHILE I < J DO
         SET OutputRoot.*[I] = InputRoot.*[I];
         SET I = I + 1;
       END WHILE;
     END;
   
   END MODULE;
   
   CREATE COMPUTE MODULE DemoCustomer_WebService_v20_CreateWSResponse
     CREATE FUNCTION Main() RETURNS BOOLEAN
     BEGIN
       CALL CopyMessageHeaders();
       SET OutputRoot.SOAP.Body.intf:updateCustomerResponse.updateCustomerReturn = 'Updated Customer via WebService version 2.0';
       RETURN TRUE;
     END;
   
     CREATE PROCEDURE CopyMessageHeaders() BEGIN
       DECLARE I INTEGER;
       DECLARE J INTEGER;
       SET I = 1;
       SET J = CARDINALITY(InputRoot.*[]);
       WHILE I < J DO
         SET OutputRoot.*[I] = InputRoot.*[I];
         SET I = I + 1;
       END WHILE;
     END;
   
   END MODULE;
   
   

8. Save the ESQL file.
9. Ensure that the ESQL module property in the Create WS Response node points to the DemoCustomer_WebService_v10_CreateWSResponse module.
10. Save the message flow.
11. Make a copy of the DemoCustomer_WebService_v10.msgflow flow, calling the new flow DemoCustomer_WebService_v20.msgflow.
12. Configure the ESQL module property in the Create WS Response node to point to the DemoCustomer_WebService_v20_CreateWSResponse module.
13. Save the message flow.
    

You can now create the main WSRR Connectivity message flow, which will invoke these Web Services: Creating the main flow.
