I am new to flowable and trying to replace our existing Bpel process with BPMN. Basically all I am trying to achieve is to invoke some web services that are ssl/ws-secured, via service tasks in a bpmn process, without using java delegates. However, I am not able to figure out how can I add security header with a username token to my web service call. I am aware that it can be done inside java delegates. But my requirement is to do this via using BPMN xml only. Is it even doable without using java delegates? If yes, then can someone show me a sample. I am stuck at this issues since days and have exhausted all resources I could find with no success. Any response is appreciated, please.
