Hi all ,
Thanks in advance,
generally - same as You run it from command line
for example in case of windows
it will be
"cmd /c cscript your file.js"
in case of Mac it will be
Thanks. Am able to run the js file using the command in tsystem as u mentioned , but my issue is to return a value from the js function to any other component or job in talend. I used "echo" statement to throw the value , it worked .But i want to get the return value from the js function into my talend job.
Thanks in advance ,
tSystem have settings for store Standard Output and Error Output - Console and/or variable
Enable store to variables, and in case of standard output - check
Thanks. I used ,
in tjava component after writing the necessary file details in tsystem , it thrown me 'null'. Can you elaborate the method to get the value from js file a bit in detail ?
var getValues = WScript.Arguments; return "The merged values are:"+getValues(0)+"-"+getValues(1)+"."; } test();
This is the sample code on my JS file .
"cmd /c cscript samplefile.js \"test\" \"run\""
This is the code on my tsystem .
this is execution of You example in windows CMD shell
Why You expect anything other than null, if Your script return null :-)
tSystem catch output, but Your script do not have it
I have checked the option to store the tsystem output to global variable , still it throws null. If my method throws null ,what is the correct method to store the tsystem's output in a variable and how to use it in tjava or any other component ? Thanks , Praveen M.
You have some misunderstanding - Your function return information into main part of Your script, but Your script do not return anything to OS console!
tSystem store into variable or on console - Standard or Error Outputs
So for store something need to have this something :-)
My picture it is result run of Your script without talend - just under windows command line ...
because Your script do not send to Output any information ( == print), Talend nothing to store into variable
Thanks , i understand it now.
So how should i write to OS Console from my .Js file ?
I tried using echo , it does not work. Also what should be the code on t_java component to get the value from .js file
