Running shell script from Activiti

[pintu_2016]

Hi,

We are planning to use activiti for workflow management. As part of this mostly we will execute shell scripts from activiti.
Can I directly call shell scripts from activiti using shell task (without java class)?
And what are the other workaround to execute shell.

Regards

Yes, there is an OOTB shell task: http://activiti.org/userguide/index.html#bpmnShellTask

Hi,

Thanks for your quick reply.
Tried to create a very simple process, While deploying the bpmn file via activiti explorere got below error.

"Create of BPMN XML failed
Errors while parsing:[Validation set:'activiti-execute-process'|Problem:'activiti-servicetask-missing-implementation']: etc…"


Please let me know if I am missing something.

PFB the code of bpmn file.
