Setting Targets for Message Events

Setting a target for a message event requires a Target object. To create one, you require a target's organization identifier, endpoint identifier and endpoint address. You can find these values by visiting the DSF FHIR server's web interface. In the top right corner, click the Show Bookmarks button, then select Endpoint. You will be taken to a list of all Endpoints available to the FHIR server.
There are two ways of adding targets to the BPMN execution variables:

1. Adding the target in the message event implementation

In your message event implementation (the class extending AbstractTaskMessageSend), you can override AbstractTaskMessageSend#doExecute, add your targets and then call the super-method.

2. Adding the target in a service task right before the message event

This is the preferred method of this tutorial but both methods will work perfectly fine. For our use cases, we usually prefer this one since there is enough complexity to warrant putting it into a separate BPMN Service Task.

In both cases you can access methods to create and set targets through the Variables instance.
