If you want to create a job that only runs within the studio client, you need to implement the interface com.coremedia.cap.common.Job. Within the execute method you can perform the wanted operation. You can use the methods of the JobContext object to notify about a success, failure, progress or abort.

When a job gets aborted by the user (or because a job with the same groupId is already running), the method requestAbort will be called and you can stop the execution of your job and then call the notifyAbort method from the JobContext.
