Step 3: Add a Process Starter
A process starter waits for input from an external process and creates a process instance each time the input arrives. For example, the process could be waiting for a document that arrives from an application server using JMS. A process starter could also be polling a directory and start whenever a file is added.
To add a process starter, follow these steps:
Procedure
-
Choose the process to which you want to add the process starter
-
Select the palette for the process starter in the palette panel.
In our example, the
JMS Queue Receiver
is the process starter. -
Drag the process starter into the design panel.
The process starter activity replaces the default Start activity.
-
Specify configuration information, then click Apply.

Note that the default Start
activity that is included with each process you instantiate is not a process starter. A Start
activity must be called explicitly from another process.
