Create a new mediation subflow

A mediation subflow can be used in multiple mediation flows.

You create a mediation subflow implementation, and you can then use the subflow in a mediation flow by dropping the subflow implementation onto the mediation flow. This task describes how to create a mediation subflow implementation.

To create a mediation subflow:

Procedure

1. Launch the New Mediation Subflow wizard in one of the following ways:

   • In the Business Integration perspective, click File > New > Mediation subflow.

   • In the Business Integration view, select a module, mediation module, or library. Right-click and select New > Mediation subflow.

   • In the Mediation Flow editor, proceed as follows:
     1. Expand the Mediation Subflow folder in the palette, click the Subflow icon, and drop it onto the canvas.

     2. In the Subflow Selection wizard, click New to create a new mediation subflow.

2. In the New Mediation Subflow wizard, choose the project that will contain the subflow, or click New to create a new project. A mediation subflow can be created in a module, mediation module or library. Create your subflow in a library if you want to share the subflow among modules.

3. Optional: Specify a folder for the new subflow.
4. Provide a name for your subflow.

5. Click Finish. The Mediation Subflow editor opens showing an in node that represents the input terminal of the subflow instance, and an out node that represents the output terminal of the subflow instance.

6. Drag the mediation primitives from the palette onto the canvas and lay them out from left to right in processing sequence.
7. Wire the primitives to the in and out terminals and to each other, and configure the primitives in the properties editor.

8. Optional: Define the message types of the input terminal of the in node and the output terminal of the out node. Click the terminal to select it and right click > Change Message Type.

   

9. Optional: Promote properties that you want to be able to change at run time, or if you want to set the value of the property in the parent mediation flow at development time. For more information, See Promoting properties in a subflow.
10. Save your changes

What to do next

Now, you can use the subflow in a mediation flow.
