Workflow exit points

In a workflow exit point you can implement custom logic. The workflow in ION contains an activity to start that custom logic. The actual implementation is performed outside ION.

Use an exit point in these situations:

• You want to use logic that is more complex than what is possible in the expression of a Set Parameter activity.
• You require data from outside the workflow that is not provided as input for the workflow.

ION starts the custom logic for your exit point through a web service. An exit point uses a web service operation. The set of workflow parameters is used as input and output for the operation. You do not have to select the required parameters in ION. All available parameters are sent to the exit point. All workflow structures are also available as input data for the exit point. You cannot use the workflow structures as output of the workflow exits.

If you deploy the web service in your own servlet container, you can implement the exit point using the technology of your choice; for example, Java or .NET. If you deploy the web service in the ION Grid, you must write the exit point logic in Java.
