This scenario describes how to send messages from a Job to a Route using the tRouteOutput component. To do this, we need to build a Job to send the message and then create a Route using the cTalendJob component to call the Job and receive the message.

For more information about how to use the Mediation components, see Talend ESB Mediation Components Reference Guide.

Creating an Data Integration Job

In this section, we will build a Job named RouteCommunication to send the message to a Route.

Dropping and linking the components
  1. Drag and drop a tFixedFlowInput and a tRouteOutput from the Palette onto the design workspace.

  2. Right-click the tFixedFlowInput component, select Row > Main from the contextual menu and click the tRouteOutput component.

Configuring the components
  1. Double-click the tFixedFlowInput component to open its Basic settings view in the Component tab.

  2. Click the three-dot button next to Edit Schema. In the schema dialog box, click the plus button to add a new line of String type and name it body. Click OK to close the dialog box.

  3. In the Number of rows field, set the number of rows as 1.

  4. In the Mode area, select Use Single Table and input the following request in double quotation marks into the Value field:

    Hello from Talend Job!

  5. Double-click the tRouteOutput component to display its Basic settings view in the Component tab.

  6. Make sure that tRouteOutput has one element body. Set its type to Body.

  7. Press Ctrl+S to save your Job.

Creating a Mediation Route

In this section, we will switch to the Mediation perspective and create a Route to receive the message sent from the Job.

Dropping and linking the components
  1. Drag and drop a cMessagingEndpoint, a cTalendJob, and a cLog component from the Palette onto the design workspace.

  2. Link the components with the Row > Route connection as shown above.

  3. Label the components for better identification of their roles.

Configuring the components
  1. Double-click the cMessagingEndpoint component to open its Basic settings view in the Component tab.

  2. In the URI field, enter "timer://myTimer?period=2000" to start message exchanges every 2000 milliseconds.

  3. Double-click the cTalendJob component to display its Basic settings view in the Component tab.

  4. Select Job RouteCommunication from the repository.

  5. The cLog component will monitor the message exchanges and does not need any configuration.

  6. Press Ctrl+S to save your Route.

Executing the Route

Click the Run view to display it and click the Run button to launch the execution of your Route. You can also press F6 to execute it. In the execution log you will see:
