Workflow Modeler: Shell in external Task

Hi all,

Can someone say me if we can launch some shell script as an external script with a workflow designed with the workflow modeler.

I try to configure my external task with a simple shell which does nothing but i get the following in my logs:

select = 0
NULL TASK

the path to the script is correct and when i launch my script alone it works...

I use TS 6.7.1. SP1.

Thanks in advance,

Yann

Unix or Windows?
What coding language is the script written in? (sh, perl, batch, etc.)
Can you post the script code?

Make sure workflow task owner has proper permission to execute the script.

Thanks for the reply,

for the moment my script is shell and it only do an echo in LINUX.
But meanwhile, i have found what is missing.

I've added a iwcallback command and when launching my script alone with the corresponding taskid, it goes to the next step of my workflow.

My new concern is on retrieving the task id from the workflow. Apparently i need to set some "WF Variables Start Op" to get it.

Upon external task execution WF engine automatically adds the following command line arguments:
- JobID - Decimal
- TaskID - Decimal
- Task's Area Vpath
- List of attached Files in the form of area-relative Paths.
Global iw.cfg switch exists to block File List arguments

No - you need to spend a bit more time reading the manuals and perhaps taking some training - the taskid is being passed to your script - you're just not looking for / using it.

Thanks for your valuable response Fish,

I spent a lot of time reading the manual wfm_1001_user_v01_en.pdf but i'm not able to find this information.
Maybe it's on the workflow dev guide.
