Issue With External Task(command working but not writting the output)

hi

i m using an external task to get the the task's associated with the workflow .finally trying to write the output that are (task's IDs) to a text file using redirect operator in dos.

the external task command is:

CMD.EXE /C $IW_HOME\local\bin\Test1.cmd

and the file Test1.cmd is like this


setlocal

set branch=%1
set iwhome=%2
set task=%4

%iwhome%\bin\iwgetfilejobs %branch%/WORKAREA/myworkarea/htdocs/index.html>C:/iw-home/local/bin/test123.txt %iwhome%\bin\iwcallback %task% 0

The problem is that when we instantiate the workflow ,the task runs and the output file(i.e txt file ) also gets created but without any contents(means to say blank file)...But when we try the command directly on server it executes and also creates the ouput file with the associated task id's.

can somebody let me know what's wrong with the approach...or their is any other approach to followed ......?

thanks in advance......

After creation of the file dynamically, are you changing the file permissions so that the user can write on the file using chmod command?

Also, if possible try to attach the code of the external task.

CMD.EXE /C $IW_HOME\local\bin\Test.cmd $IW_BRANCH $IW_HOME

Have you tried running the command directly from the command prompt instead of it being called from a workflow?

I strongly recommend that you learn Perl
I also suggest you try explaining this line of code:

%iwhome%\bin\iwgetfilejobs %branch%/WORKAREA/myworkarea/htdocs/index.html>C:/iw-home/local/bin/test123.txt %iwhome%\bin\iwcallback %task% 0

as it looks like the programmatic equivalent of a run-on sentence

You can write a ipl in that execute the CLT. Grab the output in a variable then write that variable to a file.

Give the ipl path to external task as a command.

i tried it and its working fine,the command executes and create the txt file and write the output to it........
