The problem in your case is likely related to your use of annotations for configuration. Activiti inside of Alfresco (the embedded workflow engine) does not support configuration by annotation, and as such, all of your services that you specified via Autowired will not be set, causing NullPointerException upon access. You need to use Spring XML to define an instance of your listener, expose that bean to the Activiti engine, and then use a delegate expression instead of the class name to pick up the configured instance as a listener.</P></BODY></HTML> Tue, 04 Sep 2018 08:16:49 GMT https://connect.hyland.com/t5/alfresco-forum/custom-task-listener-in-java/m-p/70238#M23109 afaust 2018-09-04T08:16:49Z
