Selecting the service to Trigger and setting the service parameters
About this task

The callprocess service is one of the most important available services on the list. When you select this service, all Processes you already created in Talend Studio are listed in the Service Parameters area and you can call any of them to transform and cross-reference master data.
The parameters you need to define in the Service Parameters area differ according to the selected service in the service list. Talend Studio simplifies this task for you by creating the underlying XML code for the proper execution of the trigger.
When you select the callJob service, for example, you can access a list of all deployed Jobs directly from the Trigger editor.
